After technique scheme, left arc-chutes and right arc-chutes are all equipped with single run-on tab, and run-on tab is provided with
First partition and the second partition, effectively prevent string arc, and the first surge chamber and the indoor gold with some through holes of the second buffering
Belong to the charged particle that division board can absorb in thermal current, and reduce gas flow temperature, the reflection of thermal current can be prevented, suppress it
Back commutation, thus weakening or eliminating the electric arc producing during electric switch process, is prevented effectively from the generation of three-phase shortcircuit, separately
Outward, the second partition top is less than striking foot portion to the vertical dimension of arc extinguishing grid pieces to the vertical dimension touching bridge, can effectively keep away
Exempt from striking foot scaling loss, arc extinguishing grid pieces one end is provided with protuberance, electric arc enters from (front end) striking foot, after protuberance again
Go out from another striking foot, striking guiding is clearly convenient and striking effect is more preferable.
