ABB Unigear type ZVC switchgear Breaker AIS ABB MV Products

Medium voltage, arc-proof, air-insulated switchgear

UniGear-ABB's medium voltage air-insulated switchgear, is the result of ABB's global know-how integrated into a single technological solution and is also ABB's answer to the range of solutions demanded by global markets. The switchgear complies with IEC 62271-200 standards. Made in ABB, UniGear comes with the same design and quality standards across 5 continents, and offers the best solutions for all installations including power plants, power distribution substations, compact Motor Control Centers, double-level, duplex and special-unit switchgear.

Salient Features

  • Metal-clad, four-sided internal arc-proof construction (IAC AFLR)
  • Designed in conformance with the highest in class for minimum Loss of Service Continuity LSC-2B with metallic partitions
  • Constructed with pre-galvanized sheets without welding points, making it the most reliable switchgear in its range
  • REF542 and other high-end communicable relays offer intelligent solutions for all installation requirements
  • It is virtually maintenance-free and all circuit breaker operations can be carried out with the door closed
  • Earthing-switch is provided as an option. It is rated for full making capacity and is provided with safe and reliable position indicators
  • All compartments can be accessed from the front, hence the switchgear can be placed against the wall
  • The switchgear is provided with conventional or integrated protection and measurement systems
  • It is fitted with conventional instrument transformers or new generation sensors

Apparatus which can be installed in UniGear Switchgear

VACUUM CIRCUIT-BREAKER – CASSETTE VERSION

  • Circuit-breaker for all fields of application
  • Vacuum Interrupters, using radial magnetic field contact system, rotate arc column over the complete contact periphery  to give the best current-interruption performance at all current values
  • Epoxy resin poles for greater protection of the interrupters

VACUUM CIRCUIT-BREAKER FLOOR-ROLLING VERSION

  • Circuit-breaker for all fields of application
    • Vacuum Interrupters, using radial magnetic field contact system, rotate arc column over the complete contact periphery to give the best current-interruption performance at all current values
    • Epoxy resin poles for greater protection of the interrupters

VACUUM CIRCUIT-BREAKER WITH MAGNETIC DRIVE

  • The magnetic actuator is a bi-stable system with electromagnetic coils for driving the armature and permanent magnet for latching on to the end positions
  • All functions like charging, switching, controlling and self-diagnostics are carried out from an integrated electronic controller
  • Equipped with multi voltage feeder in direct and alternating current

VACUUM CONTACTORS

  • Optimal solution for motor and transformer switching and switching of capacitor bank for power-factor control
  • Fitted with medium voltage fuses according to DIN and BS Standards
  • Availability of operating mechanisms with electric or mechanical latching functions
  • Equipped with multi voltage feeder in direct and alternating current

Each switchboard consists of a single switchgear, which can be equipped with a circuit-breaker or contactor along with all accessories required for the switchgear. Each switchgear is provided with a metering compartment, placed in the upper part, for auxiliary instrumentation. The units can be coupled together with either ZVC or double- level units, with the possibility of extension on both ends of the switchgear. The switchgear can be accessed from both, front and rear sides for installation and maintenance purposes.

All the service operations are carried out from the front.

UniGear type ZVC switchgear for motor switching and control

Each unit is equipped with a with draw able vacuum contactor with fuses. The use of medium voltage protection fuses strongly limits the let-through fault energy, making it possible to reduce the cross-section of the connection cables to the motor. This characteristic contributes to safeguarding the insulation levels and increasing the electrical life of the cables and the machine connected. For users with high consumption levels, it is possible to fit the contactor with two fuses in parallel for each of the phases. The units can be coupled directly with the main switchgear, with the possibility of extension on both ends.

The switchgear offers:

  • Configuration for all types of motor starting
  • Reduction in the width of the switchgear and of the surface area occupied (the typical unit is 325 mm wide), also using more than one contactor for complex motor start-ups
  • The same service and maintenance procedures as the UniGear type ZS1 switchgear
  • Full access from the front
  • Typical motor start-ups: direct, reversal of direction, reactor, autotransformer, star
