Abstract
The invention relates to a UC-shaped flat screw multi-purpose grounding wire end clamp. The clamp comprises a U-shaped flat screw grounding wire end clamp, wherein a connecting rod is mounted on one side of the U-shaped flat screw grounding wire end clamp; the top end of the connecting rod is connected with a fixed pressure plate, and the bottom end of the connecting rod is connected with a screw rod seat; the top end of a screw rod penetrates the screw rod seat to be connected with a movable pressure plate; the bottom end of the screw rod is connected with a connecting handle; and the movable pressure plate can slide up and down along the connecting rod under the action of the screw rod. The clamp provided by the invention can be used for hanging not only a steel-cored aluminium strand, but also a transformer outlet horizontal bus bar or a distribution line vertical bus aluminium bar of the transformer and a circuit breaker, and achieves the purpose that the grounding wire is multi-purpose. As an anti-slip hook is arranged on the outer side end of the fixed pressure plate and the grounding wire is not easy to fall off in fixed rotating, the effective contact area can meet the standard. As proved by field experiments, the new grounding wire is not easy to fall off during mounting and rotating, the operation is convenient and simple, and the effective contact area can meet the requirement of the grounding wire.
Description
Technical field
The present invention relates to a kind of earth connection head-clamp, especially relate to a kind of UC type plain end screw formula and use the earth connection head-clamp more.
Background technology
Old-fashioned U type earth connection the end of a thread folder can only be used for the suspension of steel reinforced aluminium conductor, allots line vertical bus aluminium row and is prone to come off when the flat hard bus row of suspension or capacitor, circuit breaker, can not guarantee power failure equipments maintainer's safety.Old-fashioned C molded lines folder belongs to non-bearing type lead and connects gold utensil.This C molded lines folder, by C shape element, two of the connection of working in coordination press piece; Connecting bolt and nut are formed, and C shape element is C type cross section, and two ends have the rectangular circulus of circular arc inner surface wing lug; Two press piece one side end and are indent circular arc wire casing; And another side end is respectively dumbbell shaped end structure cylinder and cooperate the opening circular groove of suit with it, press interblock to be connected, and certain angle rotates relatively; Correspondence position at correspondence position that presses piece and C shape element has perforate, connecting bolt and nut be connected C shape element with press piece.Can only be applied to substation transformer outlet horizontal bus row or capacitor, circuit breaker is allotted line vertical bus aluminium row, and very easily come off during fixing rotation, and effectively contact area has certain potential safety hazard less than 1/2nd.
Summary of the invention
The technical problem that the present invention will solve provides a kind of UC type plain end screw formula and uses the earth connection head-clamp more, and this earth connection head-clamp can usefulness more than one, and difficult drop-off during fixing rotation is safe and reliable.
In order to solve the problem that prior art exists, the technical scheme that the present invention adopts is:
UC type plain end screw formula is used the earth connection head-clamp more; Include U type plain end screw formula and draw ground clamp, U type plain end screw formula draws a side of ground clamp that connecting rod is installed, and the top of connecting rod links to each other with fixation clip; The bottom of connecting rod links to each other with screw bolt seat; The top of screw rod links to each other with movable pressing board after passing screw bolt seat, and the bottom of screw rod links to each other with connection handle, and movable pressing board can slide up and down along connecting rod under the drive of screw rod.
The outboard end of described fixation clip is provided with the anti-slip hook.
Advantage and effect that the present invention had are:
UC type plain end screw formula of the present invention how with the earth connection head-clamp because U type earth connection the end of a thread that will be old-fashioned presss from both sides and C molded lines chuck unites two into one; Not only can hang steel reinforced aluminium conductor but also can hang transformer outlet horizontal bus row or capacitor, circuit breaker are allotted line vertical bus aluminium row, can play the multiduty effect of a ground wire.And because the outboard end of described fixation clip is provided with the anti-slip hook, difficult drop-off during fixing the rotation, and effectively contact area can reach standard-required.Through field experiment, new earth connection difficult drop-off in rotary course is installed, convenient and simple for operation, effectively contact area meets the earth connection requirement.Simple in structure, cost is extremely cheap, and practicality is strong especially, has most importantly increased the serviceability of ground wire and has improved the utilization rate of every earth connection greatly, has accomplished that a winding ground wire can accomplish the transformer station of 220kV and 66kV administration general.Also for operations staff's changeable power plant operation has alleviated little by little trouble, help operation simultaneously.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Among the figure: U type plain end screw formula is drawn ground clamp 1, ground wire metal flexible joint part 11, metal earth anchorage clip 12, connection handle 13, anti-slip hook 4, connecting rod 3, fixation clip 2, screw bolt seat 6, movable pressing board 5, screw rod 7, connection handle 8.
Embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description:
As shown in Figure 1; How UC type plain end screw formula of the present invention is that old-fashioned U type earth connection the end of a thread folder and C molded lines chuck are united two into one with the earth connection head-clamp; It includes U type plain end screw formula and draws ground clamp 1; U type plain end screw formula draws ground clamp 1 to include ground wire metal flexible joint part 1, metal earth anchorage clip 2 and connection handle 13, is connected with insulating bar with connection handle 13 during the installing ground wire.The side that U type plain end screw formula draws ground clamp 1 to be provided with connection handle 13 is equipped with connecting rod 4; The top of connecting rod 3 links to each other with fixation clip 2; The bottom of connecting rod 3 links to each other with screw bolt seat 6, and the top of screw rod 7 is passed screw bolt seat 6 backs and linked to each other with movable pressing board 5, and the bottom of screw rod 7 links to each other with connection handle 8; Connection handle 8 is connected with insulating bar during the installing ground wire, and movable pressing board 5 can slide up and down along connecting rod 3 under the drive of screw rod 7.
The outboard end of described fixation clip 2 is provided with anti-slip hook 4; Anti-slip hook 4 can play backstop action in rotary course is installed; Prevent that ground wire from coming off from power failure equipments, effectively contact area meets the earth connection requirement, guarantees maintainer's life security.
