12kV 24kV Vacuum Circuit Breaker Isolation Handcart for switchgear
Product Description
A vacuum circuit breaker (VCB) handcart is a withdrawable trolley-type component for indoor AC high-voltage switchgear, supporting convenient installation, maintenance and testing. Equipped with five-prevention safety interlocks, it enables safe disconnection from busbars and fast replacement of circuit breakers or voltage transformers (PT) in integrated switch cabinets.
Key Features
Withdrawable Structure: Allows fast maintenance and replacement through guide rails.
High-Safety Interlock System: Complies with GB3906, IEC and other stringent standards; withdrawal is only permitted in test or isolated positions.
Wide Application: Suitable for 12kV, 24kV and 40.5kV power systems in power plants, substations, industrial and mining enterprises.
Complete Configuration: Normally equipped with chassis truck (propulsion mechanism), voltage transformers (PT), fuses and lightning arresters.
Strong Interchangeability: Supports easy replacement for various circuit breakers such as VD4 types.
Main Types
VCB Handcart: Designed for mounting vacuum circuit breakers.
PT Handcart: Used for installing voltage transformers and matching fuses.
Isolation Handcart: Applied for circuit isolation, usually without circuit breakers.
