Problems solved by technology
However, the problem of electric energy waste of electric locks is more prominent, and the electric anti-malfunction device basically supplies power around the clock throughout the year, which has caused a large waste of electric energy and caused economic losses that should have been avoided for the country.
At the same time, it also reduces the service life of the anti-mistake system, and the unsafe hidden dangers that occur from time to time.

Embodiment Construction
[0020] During normal operation, as long as the start button QA is pressed first, the A1N1 of the security section of the generator set will be introduced into the system. At this time, the red light HD is on, indicating that the current power supply is the working power supply. Otherwise, the green light LD is on, indicating that the current power supply is the backup power supply A2N2, and A2N2 is an AC 220V power supply from the security section of another unit. At this time, we can turn the transfer switch ZK on the "1" or "2" position, where the "1" position is for dealing with system defects or when power supply is required for a long time, and the "2" position is for energy saving files. It is the gear used in normal use, and we hit the "2" gear.
[0021] 1. Energy saving function
[0022]Assuming that the general operation time of our electrical operators to stop and send power does not exceed 20 minutes, we set the timer time to 20 minutes. When the system is working...

An intelligent energy-saving power supply system relates to the field of electrical misoperation prevention devices for high and low voltage switch cabinets in power systems. It is a brand-new, intelligent and energy-saving overall solution for the electrical error prevention of high and low voltage switchgear in power plants and substations. The invention is composed of an infrared human body monitoring unit, a DC power supply unit, a switching power supply unit, an intelligent interlocking anti-power-down unit, a DC power-saving unit, an intelligent charging and discharging unit, and an intelligent energy-saving unit. Realization: Intelligent recognition of the situation of personnel on site, when someone enters the site, the anti-mistake system is automatically activated, and after the personnel completes the operation and leaves the site, the electrical anti-mistake system is automatically completely powered off, which saves more than 95% of electric energy and improves the current situation. The service life of the electric anti-misoperation device improves the stability and reliability of the anti-misoperation device. At the same time, the present invention also has the function of intelligent interlocking to prevent power failure, intelligent charging and discharging, and DC power saving, which realizes the real-time and continuity of the error prevention function.
Description
technical field [0001] The invention relates to an electrical misoperation prevention device for high and low voltage switchgears in a power system, in particular to a power supply part of the electrical misoperation prevention device for high and low voltage switchgears in power plants and substations. Background technique [0002] After retrieving relevant documents, no power system with the same structure and method as the present invention has been retrieved yet. [0003] At present, there are three kinds of anti-mistake devices commonly used in power systems: microcomputer locks, electric locks, and mechanical locks. Microcomputer locks are not a big problem because they are controlled by microcomputer software programs, so they are more energy-saving, while mechanical locks are not at all. There are such problems. The problem of electric energy waste of electric locks is more prominent, and the electric anti-misoperation device basically supplies power around the cloc...
