Analysis and Improvement of A 10 kV Switch Control Circuit Fault
The 10 kV high-voltage switch is widely used in industrial and trade enter-prises,the normal operation of its control circuit is a prerequisite for the opening and clos-ing action of the high-voltage switch,and its integrity affects the safe operation of the power supply system.Taking the failure of 10 kV high-voltage switch control circuit of a coal mill in an ironmaking plant as an example,the paper analyzes the causes of this fail-ure and the deficiencies of the switch,and puts forward the improvement measures,which provides certain references for the design of the control circuits of the related equipments and the troubleshooting.
