A high voltage arc extinguisher

Abstract

The invention discloses a high-voltage arc extinguishing cover. The high-voltage arc extinguishing cover comprises a cover body, a baseplate and an arc blowing coil; the cover body comprises a shell, a plurality of insulating plates, a plurality of arc striking corners, a plurality of deflecting plates and two first installation plates; the shell is respectively provided with a first installation plate at two sides of the length direction; the plurality of deflecting plates are arranged in the shell along the width direction of the cover body; the plurality of insulating plates are arranged between every two deflecting plates along the length direction of the cover body; the arc striking corners are appressed to the lower ends of the deflecting plates; simultaneously, the arc striking corners are appressed to the two end faces of the deflecting plates; furthermore, the two ends of the arc striking corners are towards the upper ends of the deflecting plates; the baseplate comprises a basal plate, a plurality of magnetic conduction plates, a plurality of guide plates and two second installation plates; the baseplate is installed on the lower end face of the cover body; simultaneously, each second installation plate is fixedly connected with each first installation plate; the arc blowing coil is arranged along the length direction of the cover body; and furthermore, the arc blowing coil is installed between two third magnetic conduction plates. The arc extinguishing coil disclosed by the invention can elongate electric arc to the arc striking corner, so that a part of electric arc energy can be consumed.

Description

technical field [0001] The invention relates to the technical field of arc extinguishing hoods, in particular to the technical field of high voltage arc extinguishing hoods. Background technique [0002] Existing arc extinguishing hoods can only extinguish arcs generated by small voltages; in order to extinguish arcs at high voltages such as DC1000V, DC2000V, DC3000V, DC4000V, etc., a high-voltage arc extinguishing hood is now designed, which can quickly generate high voltage The arc is extinguished to protect the safety of personnel and equipment. Contents of the invention [0003] In view of the above problems, a high-voltage arc extinguishing cover is now provided to protect the safety of personnel and equipment. [0004] In order to achieve the above purpose, the technical scheme adopted is as follows: [0005] A high voltage arc chute, including: [0006] A cover body, the cover body includes a shell, a number of insulating plates, a number of arc strike angles, a ...
