Abstract: Aiming at an internal discharge fault of tank circuit breaker, this paper analyzed each link of the fault tank circuit breaker onsite collapse, test and disintegration of returning to the factory, to find out the reason of the discharge inside the equipment. From the corner of product design and manufacturing, transportation and installation process in security, this paper researched on the influence of the fault, presenting a detailed scheme of fault handling and product improvement. Practical application verifies the correctness and rationality of the improved scheme.
Key words: tank circuit breaker; internal discharge; compressed air cylinder
