Abstract

The invention provides a 6KV isolation switch protection device, relating to the technical field of isolation switches, and solves the problems that in the prior art, in the practical application process, the effective heat radiation effect cannot be realized on the isolation switch, switch aging is easily aggravated due to heat accumulation, and a user feels uncomfortable due to the fact that hotair in an isolation hood cannot be emptied when a maintainer opens the isolation hood to overhaul an isolation switch. The protection device comprises a sliding mechanism which is connected to the front side of a protection box in a sliding mode, and a protection box which comprises a box body, a limiting plate, a limiting sliding groove and a limiting column. According to the invention, after the wire harness is connected with the isolation switch, a clamping block can automatically clamp the wire harness under the elastic force of the reset spring, and each wire externally connected with the isolation switch can be placed in a partitioned manner according to the design, so that the problem of fire caused by mutual contact of zero and live wires of the isolation switch in use is avoided.

Description

technical field [0001] The invention belongs to the technical field of isolating switches, and more specifically relates to a 6KV isolating switch protection device. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. It is generally used as a high-voltage disconnector, that is, a disconnector with a rated voltage above 1kV. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for working reliability, it is very important for the design, establishment and maintenance of substations and power plants. The impact on safe operation is greater. The ma...
