Abstract
The utility model relates to a wire clamp used for short circuit grounding of substation equipment, in particular to a closed-seam ground wire clamp. The closed-seam ground wire clamp comprises a clamp body shaped like a frame body, wherein an opening is formed in one side frame. A branch ground wire is connected to the clamp body. A clamping lip extends vertically from one end of an upper opening of a top frame of the clamp body towards one end of an opening of a bottom frame. Friction patterns are arranged on the inner surface of the top frame of the clamp body. A spring is fixed to the inner surface of the bottom frame of the clamp body. The other end of the spring is fixed to the bottom surface of an inner half clamp shaped like a plate. Friction patterns are arranged on the top surface of the inner half clamp. The top surface of the inner half clamp makes contact with the inner surface of the top frame of the clamp body. The distance between the clamping lip of the clamp body and another side frame is 2 mm larger than the width of the inner half clamp. A groove is formed in the inner surface of the top frame of the clamp body between two horizontal transverse edges, wherein the cross section of the groove is of a semicircular shape. The closed-seam ground wire clamp is composed of the clamp body and the inner half clamp, and can effectively prevent a wire, especially a flat wire, from sliding off.
Description
Technical field
The utility model relates to substation equipment short circuit grounding wire clamp used, is specially enclosed seaming earthing clamp.
Background technology
When station; much equipment all wants three-phase shortcircuit ground connection to carry out safeguard protection, and in the time of wiring, three wire clamps are clipped in respectively on the three-phase conducting wire of equipment; after being merged into a dry ground wire, the ground wire that three wire clamp tails connect is connected with earth wire pile, the three-phase shortcircuit ground connection of finishing equipment.The wire clamp using is now hinged together by two and half folders, and staff pulls open two halves through parts and clamps after wire, looses one's grip, and wire clamp is by spring force clamping wire.The two halves folder of existing wire clamp is equal in length, the seaming that becomes to clamp down on wire on wire clamp is open type seaming, there is wire slippage and potential hazard of going out from two halves wire clamp in open type seaming, the tabular wire clamp particularly being formed by orthogonal friction line, when clamping strip conductor (copper bar wire, aluminium row wire), because wire clamp and strip conductor are vertical state, the slippage moment that wire clamp deadweight forms strip conductor, full moment of friction of producing by wire clamp clamping face is carried out balance, as because of carelessness, pull ground connection main line, wire clamp clamping face deficiency, just has the dangerous situation of wire clamp slippage to produce.
Summary of the invention
The utility model is clamped wire especially when strip conductor in order to solve existing wire clamp, and wire clamp holds eely problem, and enclosed seaming earthing clamp is provided.
The utility model is to adopt following technical scheme to realize: enclosed seaming earthing clamp, comprise the clamp of the frame shaped of a side frame opening, on clamp, be connected with a ground wire, one end of clamp top margin frame upper shed place is vertically extended with tabular folder lip towards one end of boundary frame area opening part, the inner surface of the top margin frame of clamp is provided with friction line, on the inner surface of the boundary frame area of clamp, be fixed with spring, the other end of spring and tabular interior half bottom surface pressing from both sides are fixed, the end face of interior half folder is provided with friction line, and the inner surface of interior half end face of folder and the top margin frame of clamp contacts.
When use, half folder in pressing down, the top margin frame of interior half folder and clamp departs from, in wire is placed in, between half folder and the top margin frame of clamp, half folder in unclamping, under the elastic force effect of spring, the top margin frame of interior half folder and clamp is firmly clamped wire, because wire clamp deadweight forms slippage moment to wire, but folder lip on clamp top margin frame can prevent that wire is from slippage between interior half folder and the top margin frame of clamp, particularly anti-slip very effective to strip conductor; The utility model utilizes the wire clamp of clamp and an enclosed seaming of interior half folder composition, can effectively prevent the slippage of wire, particularly strip conductor.
Above-mentioned enclosed seaming earthing clamp, the distance between folder lip and the opposite side frame of described clamp is than the large 2mm of width of interior half folder, wire clamp clamping wires effective.
Above-mentioned enclosed seaming earthing clamp, friction line on the inner surface of the top margin frame of clamp is that cross section is the left twill of equilateral triangle, friction line on the end face of interior half folder is that cross section is the twill left to right of equilateral triangle, left twill is vertical with twill left to right antarafacial in 90 °, the angle of the horizontal horizontal edge of the base of left twill and clamp top margin frame is 45 °, the moment of friction that wire clamp produces is like this large, the good clamping effect of wire clamp.
Above-mentioned enclosed seaming earthing clamp, has the groove that cross section is semicircle between two horizontal horizontal edges on the inner surface of clamp top margin frame, the vertical inner surface across top margin frame of groove, facilitates wire clamp to clamp round conductor.
The utility model provides a kind of enclosed seaming earthing clamp, and the utility model utilizes the wire clamp of clamp and an enclosed seaming of interior half folder composition, can effectively prevent the slippage of wire, particularly strip conductor.
