High-/low-voltage switch intelligent control system, controller and control method

Abstract

A high- / low-voltage switch intelligent control system, a controller and a control method are provided. The high- / low-voltage switch intelligent control system includes a controller, a low-voltage switch measuring device and a high-voltage switch measuring device. The controller includes a main control module, a communication module, a timing module, a storage module and a power supply module. Thelow-voltage switch measuring device is installed at a low-voltage switch to be controlled and electrically connected with the controller, and is used for measuring the current and voltage signals of the low-voltage side and the opening / closing state signal of the low-voltage switch. The high-voltage switch measuring device is installed at a high-voltage switch to be controlled and electrically connected with the controller, and is used for measuring the current and voltage signals of the high-voltage side and the opening / closing state signal of the high-voltage switch. The main control moduleprocesses the received current and voltage signals of each phase at the low-voltage side / high-voltage side and the opening / closing state signals of the low-voltage switch / high-voltage switch to get fault information. The communication module sends the real-time data of the equipment, the opening / closing state information of the low-voltage switch / high-voltage switch and the fault information to the background, and receives operation instructions from the background.

Description

technical field [0001] The invention relates to the field of switch intelligent control, in particular to a high and low voltage switch intelligent control system, controller and control method. Background technique [0002] In modern society, electrical equipment is widely used in various fields of production and life. At the same time, the corresponding electrical automation control has greatly improved production efficiency and produced greater economic and social security benefits. Traditional electrical controllers cannot simultaneously realize linkage remote control of high-voltage line equipment and low-voltage line equipment. In the existing technology, if it is necessary to shut down the switch at the upper and lower ends of a certain transformer, it is necessary to manually carry a high-voltage insulating operating rod and wear insulating gloves and insulating shoes. Go to the site to switch on the low-voltage side switch at the lower port of the transformer, and t...

AI Technical Summary

Problems solved by technology

When the transformer is overloaded, it cannot be found and adjusted or shut down in time. Most of the dangers are not known until there is a failure or burnout, which leads to frequent on-site repairs by electric power workers. Especially in the peak summer season, it is easy to cause frequent personal safety accidents for workers.

To sum up, the current operating methods of transformers and high-voltage and low-voltage switches at the upper and lower ends still have the above-mentioned defects and potential safety hazards, as well as no-load waste, failure to save energy and reduce emissions in time, and low labor efficiency, which is not conducive to overall control and safe use of electricity.
