Abstract
The utility model discloses a multifunctional grounding wire clamp composed of a lateral U-shaped fixed clamp plate and a moving tongue plate which is provided with a control rod. The moving tongue plate is sheathed in the lateral U-shaped fixed clamp plate through the control rod, the upper half part of the control rod adjusts up-and-down displacement of the moving tongue plate in the lateral U-shaped fixed clamp plate with a threaded structure, the lower half part of the control rod is made of insulation material, and the lateral U-shaped fixed clamp plate and the moving tongue plate are made of conductive material. The multifunctional grounding wire clamp is characterized in that the an upper semicircular groove is arranged in the top part of the lateral U-shaped fixed clamp plate, and a lower semicircular groove corresponding to the upper semicircular groove is arranged in the upper surface of the moving tongue plate. The multifunctional grounding wire clamp is suitable for clamping circular wires, rectangular wires and rectangular multi-layer bus-bars of different functions, is convenient to operate, safe and reliable, and can be used for changing the present situation of wide-variety and non-uniform grounding wires of a substation, effectively reducing the labor intensity of workers and improving the work efficiency.
Description
Technical field
The utility model relates to a kind of security tool that can clamp high-voltage conducting wires, high voltage bus row, specifically a kind of multifunctional grounded wire clamp.
Background technology
Hanging earthing conductor bleeds off residual charge on the high-tension apparatus after having a power failure on high-voltage conducting wires or the bus bar, is one safety curtain of protection maintainer operation on high-tension apparatus, can prevent that the unexpected incoming call of high-tension line is to the injury of human body.For a long time, the high-voltage grounding wire wire clamp transformer station uses mainly contains two kinds of single flat mouth type and single hook type, opens between the jaws up and down apart from 5 centimetres of less thaies.There is drawback in these two types of earthing clamps: the one, and round conductor can only be pressed from both sides and maybe the single rectangular wire can only be pressed from both sides, can not be mutually general, use for on-the-spot hanging earthing conductor operation and make troubles, increased the work burden, operating efficiency is not high.The 2nd, the present 35kV of transformer station, 10kV bus bar be for satisfying the large requirement of discharge capacity, uses multilayer (two-layer, three layers) rectangular conductor comprehensively, and thickness is all above 5 centimetres, and flat mouth originally, round mouth earthing clamp A/F can't meet the demands.
Summary of the invention
The utility model is the weak point that exists for overcoming prior art, a kind of multifunctional grounded wire clamp that can be satisfied with simultaneously uses such as hanging round conductor, rectangular conductor, multilayer rectangle bus bar is provided, the difficult problem that substation grounding wire clamp kind is many to solve, the multilayer rectangle wire can't direct general hanging earthing conductor, reduce the operating personnel changes the earth connection type back and forth at Substation Operating time, thereby increase work efficiency, fall the light work burden.
The utility model is that the technical solution problem adopts following technical scheme to be:
A kind of multifunctional grounded wire clamp of the utility model forms by the U-shaped strap of side with the movable hyoplastron of control lever; Described movable hyoplastron utilizes described control lever to be sleeved in the U-shaped strap of described side, and the first half of described control lever is to regulate the upper and lower displacement in the U-shaped strap of side of described movable hyoplastron with helicitic texture; The latter half of described control lever is the insulation material, the U-shaped strap of described side and movable hyoplastron are conductive material, the top that it is characterized in that the U-shaped strap of described side is provided with the upper semi-circle connected in star, and the upper surface of described movable hyoplastron is provided with the lower semi-circular groove that corresponds to the upper semi-circle connected in star.
The characteristics of the multifunctional grounded wire clamp of the utility model also are: when described movable hyoplastron) when being positioned at the bottom of the U-shaped strap of described side, aperture pitch between the top of the U-shaped strap of described side and the described movable hyoplastron upper surface is more than or equal to 10cm, and the helicitic texture length of described control lever is not less than 10cm.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1. the upper surface of the top of strap of the present utility model and movable hyoplastron is with semi-circular groove, all round conductor requirements of folder had both been satisfied, satisfy again the requirement of folder rectangular conductor, on-the-spot easy to use and flexible, reduced the time that the operating personnel of transformer station changes the earth connection type back and forth, increase work efficiency, reduced operating personnel's labour intensity.
2. open between strap of the present utility model and the movable hyoplastron port apart from large, solved the deficiency that transformer station's multilayer rectangle wire, super thick bus bar can't ground connection, for upkeep operation personnel job safety provides guarantee.
3. the utility model adopts brass material to make, and is used in conjunction with corresponding earth connection, has that discharge capacity is large, the characteristics that conduct electricity very well, and is easy to process, be applicable to various electric pressure equipment power failure ground connection operations.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: the U-shaped strap of 1 side, 2 movable hyoplastrons, 3 control levers, 4 upper semi-circle connected in stars, 5 lower semi-circular grooves, 6 bolts, 7 connect wires.
Embodiment
As shown in Figure 1, in the present embodiment, a kind of multifunctional grounded wire clamp is to be engaged in the requisite a kind of security tool of electrical installation, must be used in conjunction with just valuable with earth connection, be used for the high pressure bus bars such as high-voltage conducting wires or transformer station, switchyard, current conversion station, after will having a power failure on the high-tension apparatus residual charge bleed off, guarantee the upkeep operation personal security.This multifunctional grounded wire clamp is that the batt joint ground clamp pattern in the prior art is the basis, comprises by the U-shaped strap 1 of side with the movable hyoplastron 2 of control lever 3 forming; Movable hyoplastron 2 utilizes control lever 3 to be sleeved in the U-shaped strap 1 of side, and the first half of control lever 3 is helicitic texture, is used for adjusting activity hyoplastron 2 in U-shaped strap 1 upper and lower displacement of side; When movable hyoplastron 2 is clamped wire with the top of the U-shaped strap 1 of side, utilize the fastening movable hyoplastron 2 of control lever 3 rotations, the latter half of control lever 3 is set to the material that insulate, the U-shaped strap 1 of side and movable hyoplastron 2 are conductive material, for example adopt brass, its design feature is that the top of the U-shaped strap 1 of side is provided with upper semi-circle connected in star 4, the upper surface of movable hyoplastron 2 is provided with the lower semi-circular groove 5 that corresponds to upper semi-circle connected in star 4, both satisfy all round conductor requirements of folder, satisfied again folder rectangular conductor, substation bus bar row requirement.
When movable hyoplastron 2 is positioned at the bottom of the U-shaped strap 1 of side, aperture pitch between the top of the U-shaped strap 1 of side and movable hyoplastron 2 upper surfaces is more than or equal to 10cm, solved the deficiency that transformer station's multilayer rectangle wire, super thick bus bar can't ground connection, accordingly, the helicitic texture length of control lever 3 is not less than 10cm, to guarantee moving freely of movable hyoplastron 2, aperture pitch is adjusted in flexibility.
