Abstract

The invention relates to a high-voltage switch and a control method thereof. The method comprises the following steps of: dividing a tripping stroke and / or a closing stroke of a high-voltage switch into at least two sections; setting a direction of a force applied by the winding to control the high-voltage switch to perform a tripping or closing action; and setting the windings of different sizesin each interval to control the speed of the different high-voltage switches to perform the opening and closing operations, wherein the force subjected by the windings in the interval in the initial stage of the opening stroke or the closing stroke is greater than the force subjected by the windings in the interval in the ending stage. The invention adjusts different parameters for different voltage grade products, that is, according to the requirements, the direction and size of the different windings are set in each interval, so that different magnetic mechanisms are not needed for the mechanical characteristics of the high voltage switches of different voltage levels, thereby meeting the requirements of different mechanical characteristics of different voltage grades, and realizing thedifferential customization of different high voltage switches.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electric power engineering, and in particular relates to a high-voltage switch and a control method thereof. Background technique [0002] Since the 1990s, in order to speed up the development of my country's power industry, realize the automation of distribution networks, and meet the needs of users for power quality, various power companies have successively increased their investment in distribution networks. As the most important switching equipment in the power grid, the high-voltage circuit breaker can complete the breaking action in time and remove the fault when a short-circuit fault occurs in the power grid, so as to ensure the safe and reliable operation of the power grid. Therefore, the reliability and intelligence of the high-voltage circuit breaker have great impact on the power system. Stability and degree of automation are of great importance. [0003] Among them, the operatin...
