Five-prevention universal unlocking key intelligent box of transformer substation

Abstract

The invention discloses a five-prevention universal unlocking key intelligent box of a transformer substation, comprising a box body. The box body is internally provided with a microcomputer controller and a universal unlocking key, wherein the surface of the microcomputer controller is provided with a display screen, a selection button and a digital button, the box body is provided with a box door, and an electromagnetic lock is arranged at the open and close part of the box door and connected with the microcomputer controller through a signal line. The opening and closing of the box door are controlled by the microcomputer controller. The box door has simple structure, small volume, low energy consumption, strong control function and is flexibly expanded; the management flow of the box body is simple and the records can be checked; because a direct-current system is adopted by the box body power, people do not worry about power failure; thousands of passwords are stored in the microcomputer controller and saved in a coder, thereby being convenient for finding passwords; a piece of glass is clamped in the middle of the box door and can be broken in special circumstances for usingthe universal unlocking key to carrying out the operation of the five-prevention locking device.

Description

technical field [0001] The invention belongs to the technical field of "five defenses" in electric power systems, and in particular relates to a "five defenses" universal unlocking key smart box for a substation. Background technique [0002] "Five-proof" locking devices are widely used in modern power systems, and the "five-proof" devices are used to avoid various misuse accidents, and the unlock key is an important part of the "five-proof" devices. Due to the lack of maintenance of the "five-defense" locking device, the computer key program sometimes becomes confused, which makes it impossible to use the key to unlock the lock according to the steps. In addition, in order to shorten the processing time, reduce power outages and equipment damage in accident handling or abnormal situations, it is necessary to Operations under non-program conditions require the use of the "five defenses" master key. However, the non-standard use of the "five-defense" master key, or the unaut...

AI Technical Summary

Problems solved by technology

Due to the lack of maintenance of the "five-defense" locking device, the computer key program sometimes becomes confused, which makes it impossible to use the key to unlock the lock according to the steps. In addition, in order to shorten the processing time, reduce power outages and equipment damage in accident handling or abnormal situations, it is necessary to In the case of non-program operation, you need to use the "five defenses" master key

However, the non-standard use of the "five-proof" master key, or the private expansion of the use of the master unlocking key, has led to frequent misuse accidents and caused many hidden dangers to safety.
