Process for treating leaks on tops of substation outdoor electric isolating switch operation boxes

Abstract

The invention provides a process for treating leaks on tops of substation outdoor electric isolating switch operation boxes. The process comprises the following steps: performing rigorous basic derusting and dedusting treatment by use of a steel derusting agent; compactly winding a polyfluortetraethylene tape round a leak; using an HGM901 quick-acting plugging agent to render; performing repairingtreatment by use of a TS2111 super-metal repairing agent as an industrial repairing agent; and treating appearance after finishing a curing process. An on-site repairing technique implemented on thebasis of the prior isolating switch operation box has the characteristics of convenient operation, low cost and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of physics, and further relates to a repair process for leaks on the top of an outdoor electric isolating switch operation box of a substation. Background technique [0002] At present, there are mainly the following methods for dealing with large gaps and leaks on the top of the outdoor electric isolating switch operation box of the substation: [0003] 1. Overall replacement: the cost is high and the work requires a power outage. After the replacement, it is necessary to carry out corresponding anti-rust and painting work on the newly replaced parts. The required equipment costs and maintenance costs are high, and the working hours are relatively long. long and low economic efficiency. [0004] 2. Use oil sludge to seal: After such measures are taken to seal, although a large amount of rainwater will not enter temporarily, the disadvantage is that after being exposed to wind and sun, it will appear dry an...

Problems solved by technology

[0003] 1. Overall replacement: the cost is high and the work requires a power outage. After the replacement, it is necessary to carry out corresponding anti-rust and painting work on the newly replaced parts. The required equipment costs and maintenance costs are high, and the working hours are relatively long. long, less economical

[0004] 2. Use oil sludge to seal: After such measures are taken to seal, although a large amount of rainwater will not enter temporarily, the disadvantage is that after being exposed to wind and sun, it will appear dry and cracked, and the good effect cannot be maintained for a long time.

During the operation of the substation, due to the large rainfall in summer and autumn, rainwater seeps into the auxiliary switch in the operation box of the electric isolating switch from the crack, resulting in DC grounding, which brings great unsafe factors to the safe operation of the substation. Isolation switch operation box, causing DC grounding accounted for more than 65% from 2007 to 2008, serious water accumulation caused DC system grounding and large area of ​​corrosion in the operation box

If the operation box of the electric isolating switch is replaced, the equipment must be powered off, which will not only cause a power outage to the outside world, but also increase the maintenance cost due to the replacement of the entire set of electric isolating switch operation box
