Position detection protection device for novel double-throw high-voltage isolating switch

Abstract

According to the scheme, along with on-off rotation of a double-throw high-voltage isolating switch, when the isolating switch rotates to a turn-off position, if the isolating switch is accurately inplace, after a sensing block is close to a sensing region of a proximity switch signal device, a sensing signal can be generated and transmitted to a PLC controller, and the PLC controller can determine a position and a stroke of the sensing block. If the isolating switch is not accurately in place, the sensing block is not close to the sensing region of the proximity switch signal device, no sensing signal is generated, and the PLC controller can determine a deviation position and a stroke of the sensing block. Moreover, a height position of the proximity switch signal device on a base of thedouble-throw high-voltage isolating switch is adjustable, and meanwhile, a height position of the sensing block on a rotating shaft is regulated, so that detection of a position detection protectiondevice on any height can be implemented. The position detection protection device provided by the invention completely meets functional requirements and has the characteristics of simple structure andconvenience and flexibility for checking, replacement and regulation.
