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.

Construction:

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.

Interlocks:

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.

Advanced Interlocking and Protection

This panel includes comprehensive electrical and mechanical interlocking to ensure safe and reliable operations, reducing the risk of accidental faults or misoperations. Equipped with state-of-the-art numerical or static protection relays, operators benefit from precise, responsive fault detection and isolation, safeguarding both equipment and personnel during high-stress network conditions.

Flexible, Durable Construction

Designed for a variety of environments, the panel is housed in a robust enclosure with IP4X protection (panel) and IP2X (compartment). It supports electrolytic copper or aluminum busbars and offers single or double busbar configurations upon request. Its construction meets the rigorous standards of IEC 62271-200 and IEC 62271-100, ensuring dependable performance in industrial and utility applications.

Superior Operation and Control

This vacuum circuit breaker panel facilitates seamless monitoring and control through SCADA/RTU interfaces. Featuring spring-charged, manual, or motorised operation mechanisms, users can select configurations to match their application. Six NO and six NC auxiliary contacts (typical) enable integration with wider control schemes, supporting efficient and flexible operations.

FAQs of 11-36KV Vacuum Circuit Breaker Panel:

Q: How does the vacuum circuit breaker panel ensure safe operation during switching?

A: The panel is equipped with both electrical and mechanical interlocking features that prevent unsafe operation sequences. These interlocks help to protect personnel and equipment by ensuring breakers cannot be closed or opened accidentally when earthing or isolation is engaged.

Q: What types of protection relays are available, and how do they improve safety?

A: This panel supports both numerical and static relay options, allowing customers to choose the protection system that best suits their requirements. These relays provide quick and accurate fault detection, minimizing downtime and ensuring rapid response to electrical hazards.

Q: When should I select a single or double busbar arrangement for my installation?

A: The selection depends on your operational flexibility and redundancy needs. Double busbar configurations are ideal for critical loads or where maintenance without complete shutdowns is required, while single busbar solutions suit standard distribution systems where such flexibility is unnecessary.

Q: Where can the vacuum circuit breaker panel be installed?

A: The panel is designed for indoor, floor-mounted installations. With its high degree of protection (IP4X for the panel and IP2X for compartments), it is suitable for industrial, utility, and commercial applications requiring robust medium voltage control and protection.

Q: What process ensures compliance with international safety standards?

A: Each panel is manufactured and tested in accordance with IEC 62271-200 and IEC 62271-100 standards. The process includes routine and type tests on insulation, mechanical life cycles, operational safety, and fault performance, guaranteeing adherence to required global norms.

Q: What are the main benefits of using a vacuum arc quenching medium?

A: A vacuum arc quenching medium offers fast, reliable interruption of current, minimizes contact wear, and facilitates extended mechanical life (up to 10,000 operations). This results in reduced maintenance, lower operational costs, and enhanced safety for switching high voltage currents.
