摘要

Datang Chencun hydroelectric power plant was built and operated/generated electricity in 1970. Because SN4-10G breaker of the No.1 generator of the plant was found many problems during long-term operation, HGI-2 (S) generator breaker of SF_6 was selected as the replacement by techno-economic analysis of replacing the type of generator breaker. Operating analysis of the new type breaker during the next five-year operation in the field indicates that HGI-2 (S) generator breaker has high reliability in operation, meets the need of hydro-plant of regulating peak load, clears the concealed trouble and improve the level of the plant safety operation in power system. At the same time this paper advancing some appropriately improved advice according to the secondary fault of breaker control circuit.
