Bus chamber structure of high-voltage miniaturized air-insulated switch cabinet

Abstract

The invention belongs to the technical field of switch cabinet bus chamber structures, and particularly relates to a bus chamber structure of a high-voltage miniaturized air insulation switch cabinet. The structure comprises a machine body and an air bellow, a bus area is installed on the outer side of the machine body, an installation plate is arranged on the outer wall of the bus area, and a bus sleeve is arranged on the outer side of the installation plate. A main bus is installed on the outer wall of the bus sleeve, a clamping groove is reserved in the outer wall of a damp-proof plate, a fixing block is fixed to the outer side of the clamping groove, a pressure relief channel is formed in the top of the fixing block, a spring is installed on the outer side of the pressure relief channel, a telescopic ladder is arranged on the outer wall of the spring, and a bottom plate is fixed to the bottom of the telescopic ladder. Compared with an existing switch cabinet bus chamber structure, the high-voltage miniaturized air insulation switch cabinet bus chamber structure guarantees higher insulation strength and mechanical strength of parts through structural optimization design, facilitates normal use of a circuit after insulation connection, is not prone to causing faults such as short circuit and the like, and facilitates long-term safe use.

Description

Technical field[0001]The present invention relates to the technical field of switchgear bollar chamber structures, in particular, a high-pressure miniaturized air insulated switchgear mobar chamber structure.Background technique[0002]The existing high-insulating performance is large, but the user is required to reduce the size of the switching equipment as much as possible, which requires that the switch equipment manufacturer is designed to manufacture smaller volume, but performance is Products that cannot be reduced, existing 12kV air insulated switchgear is mostly 800mm, minimum is 650mm wide, blind reduction product size will bring product performance, especially product insulation strength, this pair of high pressure Switching equipment is fatal, the decline in the insulation intensity will cause damage to the equipment for a long time, causing a short circuit to be lowered and lost.[0003]Now the market is not strong enough, and the electrical performance, mechanical propertie...

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-voltage miniaturized air-insulated switchgear busbar compartment structure to solve the problem of the general switchgear busbar compartment structure proposed in the above background technology, which is not convenient for the insulation strength and mechanical strength of the parts, so that it is not easy to connect with the insulation. The normal use of the circuit may easily cause faults such as circuit short circuit, which is not convenient for long-term safe use.
