Problems solved by technology

[0003] (1) Since the real-time self-inspection information is not uploaded to the electrical operator, and the detected fault of the anti-malfunction device itself is not alarmed and displayed, so once the fault-preventing device itself fails, the operator will not be able to know immediately
Therefore, if it cannot be dealt with in time, this will cause the failure of the anti-mistake function, and even mislead the operator and guide the misoperation, which is extremely dangerous.
[0004] (2) Since there is no microcomputer networking, it cannot meet the needs of comprehensive automation and modernization of the power system, and cannot meet the needs of sustainable development of the power system

Abstract

This invention relates to a new type of intelligent electric error-proof system turning the existing mechatronic error-proof device to a new system with networking function and realtime monitor of the high-low voltage switch cabinets including: a multiplane display unit displaying every cabinet field state, a realtime monitor alarm unit and a field video monitor unit truly realizing realtime monitor and multiplane display to clearly look up the realtime state information of each cabinet and each lock which has the functions of self test, automatic alarm and alarm- points display avoiding error operation resulted from the fault of the error-proof device also the functions of collecting video images and networking.

Description

technical field [0001] The invention relates to a device for preventing misoperation of a high and low switch cabinet in a power system, in particular to a device for preventing a misoperation of an electromechanical integration. Background technique [0002] At present, there are mainly three types of misoperation prevention devices for high and low switch cabinets in power systems: mechanical locks, microcomputer locks, and mechatronic locks (also known as electromagnetic locks, electric locks), which are widely used, but in practical applications more or less There are some problems, among which the electromechanical integration anti-mislocking (device) mainly has the following deficiencies: [0003] (1) Since the real-time self-inspection information is not uploaded to the electrical operator, and the detected malfunction of the anti-malfunction device itself is not alarmed and displayed, once the anti-malfunction device itself fails, the operator will not be able to kno...
