Abstract
With the substation integrated automation improvement developing in Ningxia power grid, 220 kV double bus bars reversal switch operation will be more and more frequently. Through the selection of switch operating sequence of bus bars connection circuit breaker control power source and bus bars isolating switch in the bus bars reversal switch operation, and the analysis of dangerous points bringing causes of poor contact or no contact on the auxiliary contact of bus bars isolating switch, puts forward precaution and control measure for the dangerous points in bus bars reversal switch operation. The application result shows that dangerous point analysis in bus bars reversal switch operation is helpful to improve operators’standardization switching operation level and prevent misoperation hap-pening.关键词
