Abstract

The invention provides a plate error prevention device and a working method thereof used for commissioning and ceasing state detection of a relay protection plate and an error prevention operation of the relay protection plate, and problems of error commission, error cease, missed commission, missed cease and the like of the plate are solved. The plate error prevention device comprises an intelligent plate, a plate controller, a transmission adapter, a computer key and a computer management system. A plate intelligent part detects commissioning and ceasing states of a plate commissioning and ceasing function part and transmits commissioning and ceasing state information to the plate controller through a communication circuit, and the plate controller uploads collected commissioning and ceasing state information of the plate to the computer management system. When the plate is needed to be operated, the computer management system forms an operation order and sends the operation order to the computer key through the transmission adapter. The computer is inserted into the corresponding plate controller. The plate controller transmits operation information to the the plate needing to be operated. An indicator light of the plate needing to be operated is on and operating the plate is prompted. After the operation of the operation order is completed, the computer key is transmitted to the computer management system back.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and specifically relates to a technology for controlling a pressing plate device for switching on and off of a relay protection device in electric power secondary equipment, especially a pressing plate error prevention device and a working method thereof. Background technique [0002] Substation switching operation is divided into primary equipment and secondary equipment, and the switching and withdrawal of protective pressure plates are the main items of secondary equipment operation. The protection pressure plate is also called the protection connecting piece. In various traditional protections, the pressure plate is used to connect or disconnect a certain circuit. It is the bridge and link for the protection device to connect with the external wiring, which is related to the function of the protection and the action outlet performance. function properly, so it is very importa...
