Abstract
High voltage switches are indispensable in power system which will control and protect the high voltage lines. According to the research of high voltage switch equipment accident rate in the international conference on power grid for according, the high voltage switch equipment mechanical failure accidents accounted for more than 70%. Thus, it is meaningful to research the switch monitoring technology and develop an integration device with easy installation and reliable data transmission. In this paper, a new type of non-contact current sensor is used to develop the online monitoring system for the mechanical characteristics of HV switches, which will monitor and analyze the action characteristics of the opening coil, closing coil and energy storage motor.
