Product Description

The 11-36KV Vacuum Circuit Breaker Panel consists of manual/motor operated spring charged mechanism of stored energy type. The closed state of breaker can perform the duty operation. You can also hand charge the springs in the event of control supply failure in less than 15 sec. Electrical Anti-pumping feature is also provided. The 11-36KV Vacuum Circuit Breaker Panel mechanism is trip free and suitable for rapid Re-closing. It also has a vacuum interrupters and is capable of switching capacitive currents and small Magnetizing current.

Salient Features:
  • Conforms to IS2147. IEC-62271-100, IEC-60298 & IEC-60694.
  • Fully compartmentalized & internal arc compliance as per standards.
  • Emergency tripping arrangement without opening the breaker chamber front door.
  • Extensible & modular construction.
  • High reliability, Re-strike free, Horizontal isolation, horizontal drawn-out.
  • Self aligning type cluster contacts for robust design.
  • Stored energy type spring closing mechanism and fully interlocked for operational safety.
  • The Metal clad VCB cubicles are fabricated using steel sheet & in house production of all critical components. It is dust & vermin proof and with degree of protection IP4X as per IS 2147 for indoor panel & IP55 for outdoor VCB Kiosk panel.
  • The Vacuum Circuit Breaker panel consists of 4 chambers namely, Breaker chamber, Metering chamber Bus Bar Chamber, CT/PT, Cable Chamber.
Breaker Chamber:
  • It consist of VCB mounted on a trolley, horizontal draw out type with self aligning type moving contacts. Fixed contacts are covered automatically by movable shutters while drawing out the VCB to ensure no direct contact with live parts.
Bus Bar Chamber:
  • The switchgear panel is provided with single/double busbar configurations with high electrical Grade Copper / Aluminum. The 3 phase Bus bars and are supported on strong epoxy insulation are fixed in delta configuration which minimises electro mechanical stresses under short circuit conditions. Bus bars are provided with H.T. Sleeve insulation.
CT/PT, Cable Chamber:
  • The CT/PT & Cable chamber is located at the rear side of the panel & ready access is available by operating the rear cover with safety weld mesh. It is possible to mount Core balance CTs with in the cubicle.
Outdoor VCB Kiosk:
  • It offers Outdoor Vacuum Circuit Breaker Kiosk for direct installation on a plinth. The power supply can be taken either through roof bushings or cable box or a combination of roof bushing and cable box. The CTs/PTs and relays are in built in the metal enclosure.
Earthing (Options):
  • Earthing is provided through a draw-out truck with solid links on the bus bar/feeder side.
  • They are provided such that breaker closing is prevented in intermediate position between service & test/isolated positions.
  • Mechanical interlocks to prevent truck racking in/out when beaker is in closed position.
  • Breaker can be inserted only when control plug & socket is in proper position.
  • Control plug & socket can be removed only in isolated position.
  • Mechanical castle interlock with upstream/downstream isolators can be provided on request.
