The next generation in ANSI medium voltage vacuum circuit breaker technology.

The AMVAC is the next generation of ANSI medium voltage vacuum circuit breaker, 

utilizing magnetic actuation technology to provide a more reliable and longer lasting solution to the industry. 

This is made possible by the simplicity of the magnetic actuator design features such as one moving part and built-in safety features.

Benefits

•Simple open and close coils, an electronic controller and capacitors for energy storage

•Requires the least maintenance of all medium voltage vacuum circuit breaker designs on the market today

•High number of operations between breaker servicing

•Increases safety by reducing personnel time in front of switchgear lineups

Features

•Rated at up to 15 kV, 3000 A, 50 kA and 27 kV, 2000 A, 25 kA

•Low-maintenance magnetic actuator mechanism and electronic controller

Although many refinements have been made throughout the 80-90

year history of the medium voltage circuit breaker, there have

been only four generations of circuit breaker design. Early circuit

breakers were spring charged units with separate close and trip

springs. These units were used for older air-magnetic breakers.

The second generation used the same mechanism modified for

use with a vacuum bottle.

New third-generation technology – Emax 2 Harness dual power conversion system

– Embedded control system for more efficient power switching

– Intuitive user interface and user-friendly human-machine interaction

– Comprehensive safety features

The Emax 2 Harness dual power conversion system is designed for ‘two inlets and one busbar’ power supply lines.

Using ABB’s latest third-generation circuit-breaker power conversion solution, the Emax 2 Harness eliminates the need for a traditional external stand-alone controller.

Emax 2 Harness can be directly through the intelligent off-trigger embedded logic to achieve efficient cooperation between the circuit breaker control, while supporting a variety of control modes, wiring, and so on.

The Emax 2 Harness supports multiple control modes, simple wiring, high reliability, shorter changeover times and intuitive control.

Emax 2 Harness is a high-performance automated power conversion system on the Emax 2 Ekip intelligent protective circuit breakers.

It provides safer and more reliable power switching without the need for additional control equipment, whilst providing circuit protection.

In industrial and power applications where efficiency and performance are delivered through digital communications, ABB is reinventing the way digital systems are embedded to help users achieve more efficient, safe and reliable power conversion.

Function Modules

Ekip Power Modules

The Ekip Power Module supplies power to all Ekip striker and modules present on the terminal box and circuit breakers from multiple auxiliary power sources (AC or DC) available in the switchgear.

The Ekip Power Module supplies power to all Ekip strippers and modules present on the terminal box and circuit breakers.

The module is mounted in the terminal box to allow installation of other advanced modules.

It can be installed in the field at any time.

Two versions are available depending on the control voltage:

– Ekip Power Module (110-240V AC/DC)

– Ekip power modules (24-48V DC)

Ekip 2K Signalling Module

The Ekip 2K signalling module is supplied with 2 input and 2 output contacts and can be used to remotely control and indicate alarm messages and circuit breaker tripping.

It can be programmed via the tripper’s display or via the Ekip Connect software.

In addition, the combination of events can be freely configured when using Ekip Connect.

The module is suitable for all Ekip Touch and Hi-Touch circuit breakers for distribution and generator protection.

Three versions of the Ekip 2K signalling module are available: Ekip 2K-1. Ekip 2K-2 and Ekip 2K-3.

E2.2. E4.2 and E6.2 can be fitted with up to 3 modules simultaneously; E1.2 can be fitted with up to 2 modules simultaneously.

Conversion Function

Automatic Operating Mode

The Harness system can be put into automatic conversion mode by using the operating mode selection button on the operation panel.

In the automatic conversion mode, the system will automatically detect the two power sources and judge whether the two power sources are normal or not.

When one of the power supply fails, the system will carry out automatic power conversion; at the same time, in order to adapt to the fluctuation of the power grid, the conversion process can support the action delay setting.

Self-input and self-recovery

When one of the two power sources fails, the system will automatically disconnect and switch to the other one to supply power to the load.

When the faulty power supply returns to normal, it will automatically return to the state where the two power supplies are powered separately.

Self-throw without self-recovery

When one of the two power supplies fails, it will automatically disconnect and switch to the other one to supply power to the load.

When the faulted power supply returns to normal, it is necessary to select the self-recovery button or operate manually to return to the state of ‘CB1 closing/CB3 opening/CB2 closing’.

Manual switching of operating modes (non-parallel)

The Harness system can also be operated manually via the control panel, which allows manual control of the CB1 closing/ CB3 opening/ CB2 closing by means of the closing and splitting buttons.

The manual mode of operation is a ‘non-parallel’ mode, which supports electrical interlocking to prevent manual operation. At the same time, it supports the function of disconnection blocking, which guarantees the safety of the power supply system.

The power supply system is safe and secure. The parallel switching mode is used for planned maintenance or power failure of the incoming power supply line.

The CB1/CB2 is operated in the form of a ‘close first, split second’ mode to ensure that there is no interruption of power supply during the conversion process.

(The parallel connection time of power supply 1/2 is not more than 200ms.) At the same time of parallel connection operation, the synchronisation verification module detects the synchronisation condition of the two power supplies.

If the two power supplies are in the synchronous state, the synchronous indicator will light up automatically, and you can enter the manual parallel conversion operation;

If the conditions for parallel connection are not sufficient, the synchronisation indicator goes out, the circuit breaker automatically locks the closing function of the mother switch, and the parallel conversion operation cannot be completed.

Symphony Plus controllers seamlessly integrate field devices via the PDP800 PROFIBUS interface module.

This allows access to a wide range of intelligent field devices, including transmitters, actuators, motor control centres (MCCs), flame scanners, intelligent electronics and more.

These devices come from ABB and other third-party vendors.

PROFIBUS I/O and associated control strategies are configured using ABB’s extensive field-proven standard function code algorithms and S+ Engineering’s graphical design tools.

In addition, these data are made available to other S+ system nodes (i.e. Control, Operations, Engineering and Information) via a redundant plant network (PN800).

PDP800 PROFIBUS interface features include

– Support for PROFIBUS DP V0. V1. V2

– Support for PROFIBUS PA devices via DP/PA linked devices

– Support for 1 ms device timestamps via PROFIBUS DP V2

– Support for electrical and fibre optic media for PROFIBUS DP links

– PROFIBUS DP link rate up to 12 Mbps

– PROFIBUS DP connections over fibre optics up to 15 km

Comprehensive I/O Support

The PDP800 module connects Symphony Plus controllers to the S800 I/O via PROFIBUS DP V2. The S800 I/O offers options for all signal types.

The S800 I/O offers options for all signal types, from basic analogue and digital inputs and outputs to pulse counters and intrinsically safe applications.

PROFIBUS DP V2 supports the S800 I/O Event Sequence function, which time stamps events at the source with a 1 ms accuracy.

In addition, the PDP800 supports the connection of Symphony Plus controllers to S+ Turbine dedicated modules.

Specifically, via PROFIBUS DP V2. the HPC800 supports powerful turbine control solutions.

such as turbine protection (TP800), valve positioning (VP800), automatic synchronisation of generators (AS800) and condition monitoring (MCM800).

With fibre-optic extension, PROFIBUS I/O modules and devices can be placed up to 15 km away from the PDP800.

In addition, the PDP800 modules can be located up to 3 km away from the controller via redundant HN800 fibre optic communication.
