Intelligent control method of electrified operation mechanism of high-voltage switch

Abstract

The invention relates to an intelligent control method of an electrified operation mechanism of a high-voltage switch. The method includes the steps of importing configuration files and historical data of a motor to form a stepping curve in the motor transmission and energy storage process in a fitting mode, monitoring the real-time process amount of the motor and the dynamic process of switching on and switching off of the switch, performing analysis in combination with the stepping curve of the transmission motor to obtain a soft contact signal of the position of the switch and a soft contact signal of energy storage of a spring, if the switch operation is not in place and a hard contact signal of the switch is consistent with the soft contact signal, calculating and outputting the position of a movable contact of the switch and the triggering angle of a rectification power supply of the transmission motor, and returning to the step of monitoring the real-time process amount of the motor and the dynamic process of the operation mechanism. While self-diagnosis is achieved, speed changing control is performed on the motor, the phenomena such as coil burnt damage caused by frustration of an operation process or being not in place of the opening state are avoided, and the motor is protected to the maximum. The intelligent operation of the operation mechanism can be achieved without changing the original structure, and the method is easy and convenient to use and high in performance cost ratio.

Description

technical field [0001] The invention relates to a high-voltage switch control technology in a power system, in particular to an intelligent control method for an electrified operating mechanism of a high-voltage switch. Background technique [0002] High-voltage switchgear refers to indoor and outdoor AC-DC switchgear used in power systems, used in high-voltage power grids (including power plants, substations, power transmission and distribution lines, and industrial and mining enterprises, etc.) The switch puts a part of the power equipment or line into or out of operation, and can also quickly remove the faulty part from the power grid when the power equipment or line fails, so as to ensure the normal operation of the non-faulty part of the power grid and the safety of equipment and operation and maintenance personnel. Therefore, high-voltage switchgear is a very important power transmission and distribution equipment, and its safe and reliable operation is of great signif...
