Abstract

The invention discloses a solid insulation switch cabinet with an insulation bus system and a vacuum circuit breaker handcart. High-voltage live parts of a controller, the vacuum circuit breaker handcart, a voltage transformer, the insulation bus system, an insulation cable inlet and outlet system, and an isolation switch or a grounding switch are all provided with solid insulators used for realizing mutual insulation between phases and between the phases and a grounding system. Problems of low safety and reliability and large occupied area of armored mobile vacuum solid insulation switch cabinet equipment in the prior art are solved. According to the solid insulation switch cabinet, high-voltage live terminals of components such as the vacuum circuit breaker handcart, the isolation switch, the grounding switch, the cable inlet and outlet system, the insulation bus system, and the voltage transformer are all surrounded by insulation materials, the phases and the grounding system are mutually insulated from each other, functions of conduction, isolation, grounding protection, metering, load short circuit protection, and electric appliance connection between cabinets are realized, and the requirement of the power supply and distribution system for users is met.

Description

technical field [0001] The invention relates to a high-voltage switchgear, in particular to a solid insulated switchgear with an insulated busbar system and a vacuum circuit breaker handcart. Background technique [0002] High-voltage AC vacuum solid insulated switchgear is mainly used for power distribution in industrial and mining enterprises and secondary substations in power systems, power receiving, power transmission, reactive power automatic compensation devices, and large-voltage motor startup, etc., to implement control, protection, and monitoring. use. [0003] The traditional armored mobile vacuum high-voltage solid insulated switchgear has complex wiring between equipment, low equipment integration, large floor space and required space, large installation engineering, cumbersome equipment debugging process, long construction period, and heavy operation and maintenance workload. Moreover, the insulation distance between the live parts and between the live parts a...
