Fig. 5 illustrates a high voltage switchgear static contact service panel support device (hereinafter referred to as support device) 200 according to one embodiment of the present utility model, which generally includes a first insulating cross arm support 210, a second insulating cross arm support 220, and a longitudinal link. Specifically, the second insulating crossarm support 220 is disposed parallel to the first insulating crossarm support 210, and the longitudinal link is disposed to be supported between the first insulating crossarm support 210 and the second insulating crossarm support 220. In the embodiment of the present utility model, the longitudinal links include a first longitudinal link 230 and a second longitudinal link 240 that are parallel to each other such that the first insulating crossarm support 210, the second insulating crossarm support 220, the first longitudinal link 230 and the second longitudinal link 240 are connected to each other to form a rectangular frame. The first insulating cross arm support 210 and the second insulating cross arm support 220 are made of insulating materials, and can be directly contacted with the baffle in the use process without worrying about the occurrence of an electric leakage event; the first and second longitudinal links 230, 240 are positioned between the first and second insulating cross arm supports 210, 220 to provide support, and may be made of a relatively rigid material without direct contact with the baffles.
In an embodiment of the present utility model, as shown in fig. 6, an end of the first longitudinal link 230 is taken as an example, and may include a threaded section 231, a positioning nut 232 and a locking nut 233. Specifically, the thread segments 231 are located at both ends of the longitudinal link and are provided with external threads; a positioning nut 232 is fixed to an end of the threaded section 231 adjacent to the middle of the longitudinal link; a lock nut 233 is detachably connected to the threaded section 231. In the installed state, the threaded section 231 extends through the through hole of the first or second insulating crossarm support 210 or 220, and the positioning nut 232 and the locking nut 233 restrict the first or second insulating crossarm support 210 or 220 from moving in the direction along which the longitudinal link extends to lock its position.
Preferably, the first longitudinal link 230 is a threaded section 231 to which an adjustment nut 234 may also be removably attached. In the mounted state, the adjustment nut 234 and the lock nut 233 restrict the first insulating crossarm support 210 or the second insulating crossarm support 220 from moving in the longitudinal link extension direction, and the positioning nut 232 restricts the maximum displacement of the adjustment nut 234 in the longitudinal link extension direction. The adjustment nut 234 may be used to adjust the height of the first insulating crossarm support 210 or the second insulating crossarm support 220.
