What common faults will happen at the GIS station?
The advantages of GIS equipment have the advantages such as high operational reliability, low maintenance workload, and long maintenance cycle, have been demonstrated. However, some faults occur mainly in the following aspects:
Gas leakage: This is quite common and requires frequent replenishment of gas in the GIS. In severe cases, it can cause the GIS to be forced to shut down.
High moisture content: The increase in moisture content of SF6 gas is usually associated with gas leakage. External moisture seeping into the GIS room can lead to an increase in moisture content, which is the main cause of flashover of insulators or other insulating components.
Internal discharge: Internal discharge can occur due to uncleanliness inside the GIS, accidental collisions during transportation, and poor quality of insulating components.
Internal component failure: The internal components of GIS include circuit breakers, disconnectors, load switches, grounding switches, lightning arresters, transformers, bushings, busbars, etc. Failures of these internal components occur from time to time. For example, the failure rate of switch basin insulators is 30%, and the failure rate of busbars is 15%, etc.
How to test the failures at the GIS station?
There are some methods and test equipment that can solve the problem with GIS. Wuhan Huayi Electric Power Technology is a professional manufacturer of test equipment for GIS, with more than 20 years of experience in the industry. There are common test equipment, including SF6 gas analyzer, SF6 gas filling and recovering machine, Partial discharge tester, hipot tester, Circuit breaker analyzer, and so on. Through these testing equipment. It is easy to diagnose the faults and resolve them promptly.
