Abstract

The invention discloses a GIS (Gas Insulated Switchgear) novel arc extinguishing structure comprises a first gas-guide cylinder and a second gas-guide cylinder, wherein the first gas-guide cylinder and the second gas-guide cylinder discharge top and bottom and are fixedly connected through bolts; a plate is arranged above the first gas-guide cylinder and on the inner wall of an arc extinguish chamber, and the plate has a plurality of circular holes; the first gas-guide cylinder and the second gas-guide cylinder are arranged in the arc extinguish chamber; the plate is made of brass materials; the first gas-guide cylinder and the second gas-guide cylinder both comprise round pipes and fixed rings; the fixed ring has the plurality of circular holes; the lower end of the second gas-guide cylinder is provided with a plurality of avoiding openings. The device disclosed by the invention has the advantages of simple structure, good arc extinguishing property, reliability in movement and long service life, reduces the operation work of a mechanism and the height of an integral static contact and is favorable to the development of miniaturization.

Description

technical field [0001] The invention relates to a novel arc extinguishing structure of GIS. Background technique [0002] GIS switchgear needs an arc extinguishing device. The performance of the arc extinguishing device directly affects the safe operation of the GIS switchgear. At present, the structure of the arc extinguishing device in the GIS switchgear is relatively complicated, the arc extinguishing is not accurate enough, and the arc extinguishing effect is poor. A new GIS arc extinguishing device with good arc extinguishing effect is needed. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention discloses a new GIS arc extinguishing structure. The device has simple structure, good arc extinguishing performance, reliable action, long service life, and reduces the operating work of the mechanism and the height of the entire static contact. Conducive to the development of miniaturization. [0004] To achieve the ...
