A state monitoring terminal and monitoring system for a protective platen

Abstract

The invention provides terminals and a system for monitoring protection pressing plate states. According to the terminals for monitoring the protection pressing plate states, upper covers at different positions are adopted for the throwing and receding states of protection pressing plates, the throwing and receding states of the protection pressing plates are monitored, signals are output, the throwing and receding states of the protection pressing plates can be protected, the terminals for monitoring the protection pressing plate states can be directly installed on insulating bases of the installed protection pressing plates, the position and the structure of an existing protection pressing plate do not need to be changed or replaced, and installing is easy and convenient. According to the system for monitoring the protection pressing plate states, a pressing plate signal centralized collector collects and transmits information of all the terminals for monitoring the protection pressing plate states to a monitoring computer, inspectors can easily and visually check the throwing and receding states, displayed by the monitoring computer, of the monitored protection pressing plates, and therefore the states of the pressing plates can be conveniently known in real time, and operation can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of substation equipment state monitoring, in particular to a protection pressure plate state monitoring terminal and a protection pressure plate state monitoring system using the terminal. Background technique [0002] The protective pressure plate is the most widely used in domestic protective devices because of the visibility of the connection and disconnection points after operation. At present, a large number of protective pressure plates are installed on the protection screens of power plants and substations that have been put into operation. Due to the intuitive disconnection point, the operating personnel can judge the state of the relay protection device circuit and provide protection for maintenance and operation. Great convenience. According to the position of the secondary circuit of the access protection device, the protection pressure plate can be divided into two categories: protection functio...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a protection clamp state monitoring terminal, and a protection clamp state monitoring system using the protection clamp state monitoring terminal, which is used to replace the installed protection In the case of the pressure plate, the monitoring and monitoring of the throwing and withdrawing status of the protective pressing plate is realized, so as to solve the difficulty in identifying and monitoring the throwing and withdrawing state of the installed protective pressing plate in the prior art, and it is impossible to effectively prevent the wrong throwing and wrong switching of the protective pressing plate. Problems with withdrawal and poor contact
