The casting lug thereon arranging is fixing for laminar disconnecting link, because casting lug thereon is nearer with respect to the distance of movable holddown and lower wing plate, when running into laminar disconnecting link, the stroke that hold-down bolt is less with respect to upper flange just can be fixed on laminar disconnecting link on the utility model, is conducive to improve operating efficiency of the present utility model.
On described movable holddown and lower wing plate, be provided with perpendicular to the cambered surface groove of length direction separately, and the lowermost end of cambered surface groove all intersects with the center line of hold-down bolt.
The cambered surface groove arranging is arranged to radian and treats that fixing tubular cartridge fuse or disconnecting link outer wall radian are identical, increases the contact area of the utility model and tubular cartridge fuse or disconnecting link, is conducive to improve the stability of the utility model clamping tubular cartridge fuse or disconnecting link.
The thickness of described lower wing plate, upper flange and movable holddown all at 12 millimeters within the scope of 16 millimeters, the thickness of described web at 18 millimeters within the scope of 25 millimeters.
When this thickness setting is intended to guarantee the utility model intensity, select thinner thickness, be conducive to save material usage of the present utility model.
Also comprise adjustment disk, described adjustment disk is in the form of annular discs, and adjustment disk is fixedly connected on hold-down bolt away from one end of movable holddown, and the cross section radius of adjustment disk within the scope of 35 millimeters, and is provided with asperities on the side of adjustment disk at 25 millimeters.
The adjustment disk convenient operation librarian use hand arranging directly rotates hold-down bolt, and the asperities of setting is conducive to increase the skin-friction force between adjustment disk and hand.
The material of described framework and movable holddown is glass fiber reinforced epoxy resin based composites.
Glass fiber reinforced epoxy resin based composites is according to having physics, stable chemical performance, the feature that insulation property intensity is high.
The utlity model has following beneficial effect:
1, in the utility model, the hold-down bolt arranging by adjusting, cartridge fuse or disconnecting link are fixed between movable holddown and lower wing plate reliably, like this, when live line working, can effectively prevent that the arc light producing produces harm, the fail safe of operating personnel and equipment while being conducive to improve live line working like this to operating personnel and equipment because cartridge fuse or disconnecting link come off suddenly.
2, in the utility model, the hold-down bolt arranging by adjusting, is fixed on cartridge fuse or disconnecting link between movable holddown and lower wing plate reliably, compared to existing insulating cord fixedly cartridge fuse or the disconnecting link of utilizing, the utility model fixed efficiency is high, is conducive to reduce operating personnel's labour intensity.
3, the utility model is simple in structure, easy to use, and processing and manufacturing easily and the cost of material is low.
