Secondary clamping board device for electrical power system relay protection

Abstract

The invention relates to a relay protection secondary pressure plate device for an electric power system. The relay protection secondary pressure plate device mainly comprises a pressure plate connecting column and a pressure plate column which are adjacently arranged, and a pressure plate main body formed by pressure plates connected between the pressure plate connecting column and the pressure plate column, wherein the pressure plate main body is placed on a pressure plate seat, a pressure plate cover body for covering the pressure plate main body is matched on the pressure plate seat, and an anti-malfunction locking body matched with a lock catch arranged on the pressure plate seat is arranged on the pressure plate cover body; an anti-malfunction locking code pairing frame with a lock code plate is arranged at the upper part of the pressure plate cover body, and an anti-malfunction locking head matched with the anti-malfunction locking body is arranged at one side of the pressure plate cover body; and the invention has simple structure and convenient and reliable use, can effectively prevent the incorrect manipulation accident of the secondary pressure plate in the electric power system, solves the problem the electric power system only has primary equipment for anti-malfunction and does not take reliable secondary anti-malfunction measures for long term, extends the application field of the anti-misoperation system of the microcomputer, improves the investment efficiency and especially provides assurance for safe operation of the electric network.

Description

technical field [0001] The invention relates to a secondary pressing plate device for controlling the input and exit of a relay protection device or changing the operation mode in secondary equipment of a power system, which belongs to a relay protection operation device. Background technique [0002] The relay protection device in the secondary equipment of the power system is the basic equipment to ensure the safe operation of the power primary equipment. By operating the secondary pressure plate of the relay protection, the input and exit of the protection device can be controlled, or the operation mode of the protection device can be changed. The misoperation of the secondary pressure plate may cause the power primary equipment to lose protection and endanger the safe operation of the power grid. At present, the form of pressing plate generally used in the secondary pressing plate, such as Figure 1 As shown, it includes the adjacently arranged pressure plate connecting ...

AI Technical Summary

Problems solved by technology

[0003] The anti-misoperation measures for the secondary pressure plate generally only take some measures in operation management, such as standard double naming of the secondary pressure plate for relay protection, color code management, and installation of anti-mis-touch covers, but these measures can only To remind the operator to a certain extent, it is impossible to fundamentally prevent the operator from taking the wrong interval or reversing the order of operations and causing misoperation

It can be said that technically the current secondary platen has no effective anti-misoperation measures.
