Overview of the new VD4 Medium Voltage Circuit Breaker

The new VD4 Medium Voltage Circuit Breaker is the perfect combination of vacuum interrupter design and manufacturing technology with resin-embedded pole plates and technical excellence in circuit breaker design, engineering and production.

The VD4 medium voltage circuit breaker uses vacuum interrupters embedded in resin pole plates.

Embedding the interrupters in resin poles makes the circuit breaker poles particularly robust and protects the interrupters from shock, dust build-up and moisture.

A vacuum interrupter consists of a contact and an interrupting chamber.

Vacuum interrupters Vacuum circuit breakers do not require an interrupting and insulating medium. In fact, the interrupter chamber contains no ionisable material.

In any case, the arc generated when the contacts separate consists entirely of melted and vapourised contact material.

The arc is supported by external energy until the current disappears near its natural zero point.

At this point, the load density decreases rapidly and the metal vapour condenses rapidly, leading to an extremely rapid recovery of the dielectric properties.

The vacuum interrupter thus regains its insulating capacity and its ability to withstand transient recovery voltages, and the arc is finally extinguished.

Due to the high dielectric strength achieved in a vacuum even at short distances, circuit interruption is guaranteed when the contacts separate a few milliseconds before the current passes through the natural zero point.

The special geometry of the contacts and the materials used, as well as the limited duration of the arc and the low voltage

guarantees minimum wear and a long service life of the contacts. In addition, the vacuum prevents oxidation and contamination of the contacts.

Operating mechanism type EL

The low speed of the contacts, the short running time and the low mass limit www.abb-drive.com the energy required for operation and thus ensure extremely limited wear of the system. Circuit breakers

therefore require only limited maintenance.

VD4 circuit breakers have a mechanical operating mechanism with energy storage and free tripping. These features make opening and closing operations independent of the operator.

The operating mechanism is very simple to conceive and use, can be customised with various accessories and is quick and easy to install. This simplicity makes the equipment more reliable.

Structure

The operating mechanism and the magnetic poles are fixed to a metal frame which also serves as a support for the fixed circuit breakers.

The compact construction ensures robustness and mechanical reliability.

In addition to isolating contacts for connecting auxiliary circuits and flexible cables with plugs, the

The tractable circuit breakers are also equipped with a bracket trolley for putting them into or taking them out of the switchgear or enclosure with the door closed.

The IRB 1200 is one of the latest generation of 6-axis industrial robots from ABB Robotics with a payload of 5 to 7kg.

It is designed for manufacturing industries that use robot-based flexible automation, such as the 3C industry.

The robot’s open architecture makes it particularly suitable for flexible use and allows extensive communication with external systems.

IRB 1200 Type A

Type A – Axis Calibration

The difference between the IRB 1200 and the IRB 1200 Type A is that the Type A uses axis calibration. Each axis has a bushing on which the calibration tool is mounted.

Therefore, the castings of the IRB 1200 and IRB 1200 A models are different.

How do I know the type of robot?

The type label on the robot base indicates whether the robot is axis calibrated or not.

These robots are named IRB 1200 A models.

Robots that are not axis calibrated are simply named IRB 1200 (no type indicated).

IRB 1200 Type B

Type B – SafeMove 2

The IRB 1200 Type B differs from the other IRB 1200 versions in that

Type B supports SafeMove 2.

Therefore, the following components differ from the other versions:

– Base

1.1.1 Construction

Continued

– Drive unit, shaft 2. shaft 3. shaft 5 and shaft 6

– Motor with pulley, shaft 4 and shaft 5

– Robot cable harness

– Battery pack

– SMB unit (replaces EIB unit)

The IRB 1200 B model is based on the IRB 1200 A model and therefore the B model has a bushing for mounting the calibration tool.

Therefore, Type B also has a bushing for mounting the calibration tool.

How do I know the type of robot?

The type label on the robot base indicates whether the robot supports SafeMove 2.

These robots are designated as IRB 1200 Type B.

The particulate emissions of the robot comply with the DIN EN ISO 14644-1 standard for clean room class 3.

Clean room robots are designed to work in a clean room environment.

The robot IRB 1200 is suitable for clean room environments according to IPA test results.

Clean room robots are designed to prevent the robot from emitting particles. For example, frequent maintenance work can be carried out without damaging the paintwork.

The robot is coated with four layers of polyurethane paint. The final layer is a clear coat of paint applied to the tags to simplify cleaning.

The paint has been tested for volatile organic compound (VOC) emissions and is classified according to ISO 14644-8.

IP67/66 rating

The robot is available with an optional IP67 rating. Options will add seals, machined parts, and gaskets.

Foundry Plus 2 Protection Type

Robots with the Foundry Plus 2 option are designed for harsh environments where the robot is exposed to coolants,

lubricants, and metal sprays typically used in die casting applications or other similar applications.

Typical applications include jet insertion and part removal in die casting machines, handling in sand casting and gravity casting, and more.

(see Foundry Prime Robotics for cleaning applications or other similar applications).

In foundry applications and other applications, special attention must be paid to operation and maintenance requirements.

Please contact ABB Robotics Sales if you have questions about the feasibility of specific applications for the Foundry Plus 2 protected robot.

The robot is primed with a two-component epoxy resin for corrosion protection.

To further enhance the corrosion protection, additional rust inhibitors are applied to exposed critical areas.

For example, a special anti-rust coating is applied to the tool flange. Nevertheless, continuous splashing of water or other similar rusting liquids may cause rust to adhere to unpainted areas of the robot,

seams or other unprotected surfaces. In such cases, it is recommended that a rust inhibitor be added to the fluid or that other measures be taken to prevent rust from forming in such areas.

The entire robot, from base to wrist, is IP67 compliant according to www.abb-drive.com IEC 60529. which means that the electrical compartment is hermetically sealed against water and solid contaminants.

All sensitive parts are better protected than with standard products.

Selected Foundry Plus 2 features:

– Improved sealing against ingress into the cavity to ensure IP67 compliance

– Additional protection for cables and electronic components

– Special cover plate to protect the cavity

– Proven connectors

– Black chrome-plated tool flange

– Anti-corrosion treatment of screws, washers and unpainted/finished surfaces

– Extended service and maintenance programme

The Foundry Plus 2 robot can be cleaned using appropriate cleaning equipment according to the robot product manual.

Proper cleaning and maintenance is required to maintain protection, e.g., whether the wrong cleaning method washes away the rust inhibitor.

Continuous supervision of complete trip circuit independent of circuit breaker position

The supervision relay type TCS is intended for a continuous supervision of circuit breaker trip circuit and gives an alarm for loss of auxiliary supply, faults on the trip coil or its wires independent of the breaker position, faults on the breaker auxiliary contacts and faults in the supervision relay. The trip circuit supervision is a crucial requirements as its failure can cause disconnect of possible network fault and eventually have to be cleared by another upstream protection.

In normal condition, the indicator LE D glows green and output relays www.abb-drive.com are in picked-up condition. In the event of a fault, the supervision relay operates (drops-off)after a delay of 0.6 sec and the indicator LED turns red.

TCS relay product range

• Rated voltage: 24V DC, 30V DC, 48V DC, 100-125V AC/DC, 220-250V AC/DC

• Contact configuration: 1NO+1NC+2C/O

Main benefits

• Highly reliable

• Personnel as well as power system safety

• Easy site installation

Main features

• Continuous supervision of trip circuit independent of the circuit breaker position

• Galvanic isolation between auxiliary supply and supervision circuit

• Delayed operation to avoid spurious signals during circuit breaker operation

• Enables use in sensitive or high resistance circuits

• Extremely low burden on auxiliary source

• Complete range of rated voltages either AC/DC

Features

• Continuous supervision of trip circuit independent of the circuit breaker position

• Extremely low burden on auxiliary source

•  Complete range of rated AC / DC voltage

•  Operation indication for trip circuit healthy and unhealthy

•  Low-level measuring current enables application of relay for high burden circuits

•  Delayed operation to avoid spurious signals during circuit breaker operation

•  Galvanic isolation between auxiliary supply and supervision circuit

Applications

In a protection system the tripping of circuit breaker is crucial. Should an interruption occur in a trip circuit a possible network fault would not be disconnected and the fault would have to be cleared by another up-stream protections in the power system. The supervision function is particularly important when there is only one tripping coil. CB tripping is vital, for instance, for generator circuit breakers or other important circuit breaker in distribution networks.

The supervision relay type TCS is intended for a continuous supervision of circuit breaker trip circuit and gives an alarm for loss of auxiliary supply, faults on the trip-coil or its wires independent of the breaker position, faults on the breaker auxiliary contacts and faults in the supervision relay itself.

Design and principle of operation

The supervision relay TCS is designed to be used for the supervision of trip circuits and other important control and monitoring circuits. Block diagram of the relay is shown in Fig. 1. The supervision function is based on low-level (~ 3 mA) current injection principle.

The injected current is sensed by two opto couplers. The supervision function in three

steady states of circuit breaker-trip circuit can be seen from fig.2. 3 and 4. In normal condition the indicator LED glows green and output relays are in picked-up condition.

If in the event of a fault, the measuring current goes below the operating value of the relay  (0.3 – 0.7 mA) or completely stops flowing, the supervision relay operates (drops-off) after a delay of 0.6 sec and the indicator LED turns red.

The supervision relay, for its functioning requires and auxiliary voltage (AC or DC) of rated value to be connected to the terminals “a” and “b”. This voltage can be the same as that of the supervised circuit or it could be a separate source with same magnitude (ac or dc). Should a fault occur in the auxiliary voltage supply the LED does not glow and the output relay drops off. Relays with differing rated voltage for supervision circuit and auxiliary supply can be supplied as special execution.

Introduction

The AZ100 Zirconia Oxygen Analyzer is a versatile system designed primarily for the OEM boiler and burner controls market.

The system is a low-temperature type www.abb-drive.com designed to work in process temperatures up to 800 °C (1472 °F) and with a maximum sensor mounting flange temperature of 400 °C(752 °F).

The analyzer provides oxygen computation, with readout and retransmission, based on the probe mV output signal. The output signal (E mV) is Nernstian in form and follows the equation:

E (mv) = 0.0496T(log10 P0 / P1) ± CmV

Where:  T = Absolute temperature

P0 = Reference O2 partial pressure

P1 = Sample O2 partial pressure

C = Cell constant (mV zero offset)

0.0496 = Faraday’s gas constant

Probe design

The probe uses the proven and innovative ABB electrode and cell design technology which has been so reliable in other ABB zirconia probe designs.

The flexible probe design gives a range of intake tube lengths to suit all applications and an optional filter/flame arrester making it safe for use where groups IIB and IIC gases may occur in the process being measured. The probe has options of male thread NPT or BSPT mountings. As with all previous ABB designs of low temperature probes, the AZ100 probe is site-serviceable.

As the sensor housing is located on the outside of the duct wall, diffusion of reference air into the sensor housing is sufficient; thus eliminating the need for an air pump or instrument air supply.

The reference air diffuses into the housing through a porous membrane which restricts entry to air only and maintains the IP66 (NEMA 4X) protection.

Transmitter design

The transmitter has, as standard, high/low alarm relays and a single linear or logarithmic isolated retransmission. Display features include %O2. cell temperature, heater control output, cell mV, alarm set points, calibration sequence diagnostics and output settings.

At system startup the transmitter controls the level of power to the mains-powered heater within the probe to eliminate the risk of thermal shock to the sensor.

Based on the proven 4600 Series of transmitters, the AZ100 transmitters are environmentally protected to NEMA 4X (IP65)*, and meet the requirements EN61326 for industrial locations.

The AZ100 transmitters have a green, backlit LCD display and four tactile membrane switches for operation and programming. The measured value display is a 5-digit, 7-segment LCD, while the information display is a 16-character, single line, dot-matrix.

The information display can be user-programmed for display in English, French, German or Spanish.

Real-Time Clock RTU560 Standard Time Synchronization with Longwave Transmitter DCF7

Applications

RTU560 product line units can be synchronized with the standard time of the longwave transmitter DCF77 using the module 560RTC02.

The RTU560 reads the time and date from the module 560RTC02 and synchronizes its internal clock with standard time via minute pulses.

The RTU560 synchronizes its internal clock with standard time by means of minute pulses. The use of the module 560RTC02 ensures that the indications of several end devices are synchronized when they contain time information.

Features

The longwave DCF 77 transmitter can be reliably received within a distance of approx. 1500 kilometers from Frankfurt/Main in West Germany, as well as in many parts of Europe.

If the reception level is sufficient, the module 560RTC02 will synchronize with standard time and receive the date and time within three minutes.

The communication unit (CMU) is synchronized with DCF 77 via the MIN1 pulse front. the CMU reads the time and date via the RTU system bus.

In the event of radio interference or DCF 77 interruption, the clock on the 560RTC02 will continue to use a high www.abb-drive.com precision quartz clock. The internal condenser allows the

560RTC02 to continue to control the clock (approximately 150 hours), even when the station is turned off. Upon power-up, the RTU560 will have valid time immediately.

If the DCF 77 signal fails for more than 2.5 hours or the 560RTC02 is not synchronized, the alarm relay contacts close.

In addition to the minute pulse output for RTU560 synchronization, there is also a minute pulse output which is connected to the module via an optocoupler (MIN2).

The time, date and status can be read out every minute via the serial data output interface RS232.

Four light-emitting diodes on the front panel of the 560RTC02 real-time clock are used to indicate the following operating states:

– ST: Brief board alarm

– FR: Free-running 560RTC02 not synchronized with DCF 77

– CD: Carrier Detect Carrier Detect

Receiver signal strength level; optimal positioning of the antenna for maximum reception

– MN: Pulse per minute blinking
