Electronic electromagnetic type intelligent switch for high-voltage electric power system

Abstract

The invention provides an electronic electromagnetic type intelligent switch for a high-voltage electric power system. The electronic electromagnetic type intelligent switch comprises an arc extinguishing device consisting of an insulated arc-resisting grid assembly and a coil, wherein the lower part of the arc extinguishing device is provided with a failure current tripping assembly with contacts and is provided with a matched operation mechanism, during the failure, the failure current is utilized for pushing a movable conducting rod, in addition, electric arcs are introduced into an arc extinguishing chamber for arc extinguishing, meanwhile, switches can be directly tripped off according to the failure property by the energy of the failure current, and in addition, the matched operation mechanism is adopted, so the reliability is very high, the arc extinguishing speed is extremely high, the switch operation intelligentization is realized, and the safe and stable operation level of the electric power system is improved.

Description

technical field [0001] The invention relates to a power switch, in particular to an electronic electromagnetic intelligent switch used in a high-voltage power system. Background technique [0002] The applicant disclosed an electronic electromagnetic smart switch in the utility model application with the application number 201120435098.5, including an electronic electromagnetic smart combination switch. Although this switch can achieve a certain intelligent control effect, it is not perfect enough. There are the following problems: first, the movement distance of the parallel conductive rods is relatively short, so the discharge distance for higher voltages is shorter, which makes the stability of the arc zero crossing relatively poor; second, the arc contact assembly cannot be used as an independent switch. It does not involve the cooperation of the corresponding operating mechanism. Contents of the invention [0003] In order to overcome the deficiencies in the above te...
