Abstract

The invention belongs to the field of high-voltage electric device sets and in particular relates to a high-voltage switch cabinet. The high-voltage switch cabinet comprises a cabinet shell, a bus room, a circuit breaker handcart room, a cable room and a relay meter cabinet, wherein the bus room is provided with a bus, a bus sleeve covers the bus, the circuit breaker handcart room is provided with a circuit breaker handcart, an arrester, a cable and a grounding switch are arranged in the cable room, and a current transformer is arranged on the back wall of the cable room. The high-voltage switch cabinet disclosed by the invention has the advantages that the bus sleeve covers the bus so that the insulation distance between buses and the insulation distance between each bus and the cabinet shell are reduced, and the size of the high-voltage switch cabinet is shortened; a cable room cabinet door is changed from a traditional clapboard type into a rotary shaft type, so that the cable room cabinet door can be conveniently opened and the cable room can be conveniently overhauled; and in addition, the safety performance of the high-voltage switch cabinet is increased through components, such as a voltage leaking device and the arrester.

Description

technical field

[0001] The invention belongs to the field of high-voltage complete sets of electrical equipment, in particular to a high-voltage switchgear.

[0002] Background technique

[0003] High-voltage switchgear is a complete set of switchgear and control equipment. As a power center and main power distribution device, it is mainly used for control, monitoring, measurement and protection of power lines and main electrical equipment. It is often installed in substations and power distribution rooms. . The electrical components in the cabinet include primary electrical components (main circuit equipment) and secondary components (also known as secondary equipment or auxiliary equipment, which refer to low-voltage equipment that monitors, controls, measures, adjusts and protects primary equipment).

[0004] There needs to be a certain distance between the busbars of the high-voltage switchgear in order not to interfere with each other and ensure electrical safety. Mi...
