Concentrated automatic power supply switch on and off control system for fault recorder

Abstract

A concentrated automatic power supply switch on and off control system for a fault recorder comprises an information remote transmission system mainframe, a power supply switch on and off concentrated controller, a intermediate relay and a fault recorder microcomputer processor, wherein the information remote transmission system mainframe and a power supply switch on and off concentrated controller are mounted inside a information remote transmission screen, the intermediate relay and the fault recorder microcomputer processor are mounted in a fault recorder screen, the information remote transmission system mainframe is connected with the power supply switch on and off concentrated controller through a serial port, the power supply switch on and off concentrated controller is connected with the intermediate relay through a power supply control line, the information remote transmission system mainframe is connected with the fault recorder microcomputer processor through an Ethernet switch, and the power input line of the fault recorder microcomputer processor is controlled by the intermediate relay. The concentrated automatic power supply switch on and off control system has the advantages that the problem that when the fault recorder microcomputer processor is halted, manual power off and rebooting must be performed is solved effectively, and power and rebooting of the fault recorder microcomputer processor can be performed at the first time when the processor is halted.

Description

technical field [0001] The invention belongs to the technical field of automatic control of the host computer of substation information substation, and in particular relates to a centralized automatic power switching and switching control system for fault recorders. Background technique [0002] The fault recorder is an automatic recording device that is put into operation all the year round to monitor the operation status of the power system. When the system fails, the device starts up and directly records the electrical quantities (current, voltage) and digital quantities reflecting the system faults where the device is installed. (Switch displacement, protection action, etc.) displacement is a reliable basis for analyzing system accidents. However, in actual use, the microcomputer processor of the fault recorder often crashes. If this happens, the protection personnel need to go to the scene to cut off the power of the fault recorder and restart it, and then it can retur...

AI Technical Summary

Problems solved by technology

However, in the actual use process, it often occurs that the microcomputer processor of the fault recorder crashes.

If this happens, the protection personnel need to go to the scene to cut off the power of the fault recorder and restart it, and then it can return to normal; Time, this treatment not only increases the fault elimination time of the fault recorder, increases the possibility that the fault recorder cannot record normally when the power grid fails, but also increases the on-site work intensity of the protection personnel, and also increases the fault recording time. Defect elimination cost
