AI Technical Summary
In remote mountainous areas, animals climbing on the supports of fallen fuse circuit breakers frequently cause short circuits, affecting the safe operation of the power grid.
A design includes a support plate, which is electrically insulated to increase the distance between the drop-out fuse and the support carrier. The support plate has mounting holes and is connected to the connecting group on the drop-out fuse via screws and brackets. The design adopts an insulated bracket structure, which increases the size of the drop-out fuse's metal frame plate. The metal frame plate is wrapped inside an electrically insulating outer layer. The inner wall of the through holes on the metal frame plate is wrapped by the electrically insulating outer layer to form mounting holes. The upper and lower surfaces of the support plate are equipped with rodent-proof plates.
The design of the insulated support structure and rodent barrier prevents short circuits caused by small animals climbing on the equipment, thus improving the safety of electrical equipment.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of electric power equipment support technical field, specifically to a kind of drop-out fuse support. BACKGROUND
[0002] At present, in power line construction, whether in urban area or in remote mountainous area, most electric power optical cables are basically laid in overhead mode, mainly for safety and not to affect ground building, in addition, also can prevent from being destroyed by animal gnawing. However, especially in remote mountainous area, there are more animals, for the rodent with strong climbing ability, only overhead cannot solve the problem, for drop-out fuse, it is no exception, when small animal climbs to the support of drop-out fuse through support carrier, short circuit phenomenon is easily caused, which greatly affects the safe operation of power. SUMMARY
[0003] The utility model aims at providing a kind of drop-out fuse special insulating support to avoid short circuit phenomenon.
[0004] To solve the above technical problem, the technical scheme adopted by the utility model is:
[0005] A kind of drop-out fuse special insulating support, including support plate, the plate face of the support plate and close to its two ends are respectively provided with mounting hole, the mounting hole of the one end of support plate is connected with the connecting group on drop-out fuse by screw, the mounting hole of the other end of support plate is connected with support carrier by screw, the support plate is electrically insulating support plate.
[0006] Further, the electrically insulating support plate includes electrically insulating outer layer and metal framework plate, metal framework plate is wrapped in electrically insulating outer layer, metal framework plate is provided with through-hole, the inner wall surface of the through-hole is wrapped by electrically insulating outer layer to form the mounting hole.
[0007] Further, the upper surface of the support plate is provided with upper mouse baffle.
[0008] Further, the lower surface of the support plate is provided with lower mouse baffle.
[0009] The utility model has the beneficial effects that:
[0010] The application adopts the structure form of insulating support for drop-out fuse, increases the distance between drop-out fuse and support carrier, when small animal climbs to the support of drop-out fuse, short circuit phenomenon occurs. In order to further improve safety, mouse baffle is additionally arranged on insulating support. BRIEF DESCRIPTION OF DRAWINGS
