Description
【Technical field】
The utility model is related to the disconnecting switch on air insulated switch equipment in a kind of power transmission and distribution industry, especially
It is a kind of air insulation cabinet disconnecting switch.
【Background technology】
According to industry survey and patent retrieval, the integral installation of the supporting air insulation disconnecting switch of general-purpose type transmission ＆ distribution switch cabinet
Arrangement size is larger, it is impossible to meet realize on the premise of electric insulation miniaturization install with it is supporting, when the overall width of switch cubicle
During less than or equal to 500mm, cannot also realize electrically installing and corresponding five anti-designs.Some conventional rotation double-pole double breaks are opened
Though the design of point isolation moving contact can also be met less than the demand on 600mm width, but because double-pole double break prescribes dynamic touching
The whole height that head revolution space needs reaches 622mm, electric insulation space hold more than 420mm, so as to result in switch cubicle
Whole height increase.Particularly when this disconnecting switch is designed to lower buffer action, increase because this double-pole rotates
Height directly results in the artificial operation of supporting killer switch highly exceed corresponding code requirement, while directly affecting electricity
The setting height(from bottom) of cable room cable, less than the required value of technical specification, is that the operation maintenance at scene brings extremely inconvenience.
In order to overcome above-mentioned problem, we have developed a kind of air insulation cabinet disconnecting switch.
