Abstract
High voltage vacuum contactors are widely used in high voltage power system of power plant.In order to help the field workers correctly and promptly treat the common faults of high voltage vacuum contactors
this paper introduced the working principle of high voltage vacuum contactor operating mechanism
detailedly described the common faults and treatment methods in previous operation and maintenance
and analyzed the causes of the faults.In addition
suggestions were offered to reduce the fault rate of high voltage vacuum contactors.
