Cleaning device for disconnecting switch

Abstract

The embodiment of the invention provides a cleaning device for a disconnecting switch. The cleaning device comprises an upper rod, a lower rod with the grinding function, and a lower rod with the spraying sweeping function, wherein the upper rod comprises an outer hollow rod, and an inner rod which is inserted into the outer rod and can rotate around the extending direction; the lower rod with the grinding function and the lower rod with the spraying sweeping function are selectively connected to the lower end of the upper rod; the lower rod with the grinding function comprises an outer hollow rod, and an inner rod which is inserted into the outer rod of the lower rod with the grinding function and can rotate around the extending direction; the lower rod with the spraying sweeping function comprises an outer hollow rod, and an air tube which is inserted into the outer rod of the lower rod with the spraying sweeping function. The device further comprises a coupling assembly and an air tube connector; the inner rod of the upper rod and the inner rod of the lower rod with the grinding function are linked through the coupling assembly. The device further comprises an air blowing bar and a grinding bar which are rotatably connected to the upper end of the upper rod.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution, and in particular relates to a cleaning device for an isolating switch. Background technique [0002] High-voltage disconnectors are the most widely used high-voltage switchgear in power systems, usually 2 to 4 times the number of high-voltage circuit breakers used. During use of the isolating switch, its contact finger is prone to heat. After research, there are three main causes of heat generation and treatment methods: 1. Poor contact due to oxidation of the contact finger. The treatment method can be to polish the oxide layer to remove dirt; 2. Burning of the contact finger leads to poor contact. The treatment method is to replace the contact finger; 3. , The finger pressure is not enough and the connection part is loose. The solution is to replace the spring and tighten the screw. [0003] In the maintenance work of the isolating switch, in addition to the probl...

Problems solved by technology

[0004] In the process of dealing with the problem of finger fever, based on the existing scheme, it is necessary to operate after a power outage, and the time spent waiting for power outages and arranging safety measures and permits accounts for about 50% of the entire processing process. Refers to the operation time for sanding and removing dirt, which only accounts for 20% of the total processing time
