Abstract
The utility model relates to a sulfur hexafluoride load switch housing, which comprises an upper insulating cover and a lower insulating cover, wherein a wiring post is respectively arranged on the upper insulating cover and the lower insulating cover. The housing is characterized in that the wiring post on the lower insulating cover adopts an outer convex structure with a skirt edge. Since the wiring post on the lower insulating cover adopts the outer convex structure with a skirt edge, water log and dust accumulation are avoided, and the sulfur hexafluoride load switch can also effectively guarantee safe operation in case of being mounted upside down.
Description
Technical field
The utility model relates to switch case, is a kind of sulphur hexafluoride on-load switch housing specifically.
Background technology
Along with China power transmission and transforming equipment in modern age requires to improve constantly, the applicability of sulphur hexafluoride on-load switch there has been further requirement, remove old formal dress, under the last inlet wire outside the mode of outlet, also had upside-down mounting, the requirement of outlet method on the following inlet wire, and the ratio that this mode is occupied is increasing.And existing sulphur hexafloride circuit breaker housing is divided into indent formula structure owing to following insulating lid wiring pile head, and under the upside-down mounting mode, recess meeting ponding laying dust easily causes short trouble in it, cannot say for sure to demonstrate,prove safe operation.Therefore design a kind of simple in structure and can guarantee that the sulphur hexafluoride on-load switch housing of safe operation is very necessary.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure and can guarantee the sulphur hexafluoride on-load switch housing of safe operation.
For achieving the above object, the utility model adopts following technical scheme: a kind of sulphur hexafluoride on-load switch housing, comprise insulating lid, following insulating lid, last insulating lid is provided with the wiring pile crown, following insulating lid is provided with the wiring pile crown, and the wiring pile crown under it is characterized in that on the insulating lid is an evagination band shirt rim formula structure.
Because the wiring pile crown under the utility model on the insulating lid is an evagination band shirt rim formula structure, has avoided the generation of ponding laying dust, therefore, even when the upside-down mounting of sulphur hexafluoride on-load switch, also can effectively guarantee safe operation.
