Abstract
The invention discloses a ground lead and belongs to the technical field of ground wires. The ground lead comprises a conductor grip and a brake pull-rod, wherein the conductor grip is provided with a ground cable. The lower end of the conductor grip is connected with an insulation rod provided with an inner hole, a vertical groove hole communicated with the inner hole of the insulation rod is formed in the wall at the lower end of the insulation rod, and a transverse groove hole communicated with the inner hole of the insulation rod is formed in the upper end of the vertical groove hole; a T-shaped clutch bolt is arranged at the upper end of the brake pull-rod and the T-shaped clutch bolt is matched with the inner hole, the vertical groove hole and the transverse groove hole of the insulation rod. The ground lead further comprises ground band iron and the ground cable is connected between the conductor grip and the ground band iron. According to the ground lead, the conductor grip is connected with the insulation rod through the T-shaped clutch bolt on the brake pull-rod and the T-shaped clutch bolt can be rapidly separated from the brake pull-rod when the ground lead is installed; when the conductor grip is detached, the T-shaped clutch bolt and the brake pull-rod can be rapidly combined into a whole, so that the conductor grip retreats from a transmission conductor; the ground lead is safe, convenient and rapid to operate and capable of relieving the labor intensity and improving work efficiency.
Description
Technical field
The present invention relates to earth connection technical field.
Background technology
Earth connection is to be connected on the positions such as electric equipment shell timely by the circuit of the unsafe electric charge producing because of a variety of causes or leakage current derivation.In the maintenance process of transmission line, after line outage, must connect ground wire.High-voltage grounding wire is for circuit and Substation construction, for preventing from closing on the use that guarantees safety when electrified body produces electrostatic induction electric shock or false switching.By regulation promulgated by the ministries or commissions of the Central Government, earth connection must be that the above naked copper flexible cord of 25mm * 2 is made.The step of hanging earthing conductor: (1) first links earth clip, after connect wire clamp; While removing earth connection, must first tear wire clamp open by follow procedure, after tear earth clip open.(2) ground connection annealed copper wire is fixed on the copper lug in wire clamp, the other end connects the copper lug on earth connection and is fixed on ground connection band iron, forms a set of complete earth connection.(3) examine the electric pressure of earth connection and whether the electric pressure of operating equipment is consistent.Before earth connection, should first electrical verification confirm to have a power failure, on equipment, confirm to carry out after no-voltage.In prior art, portable high-voltage grounding wire is comprised of insulating bar, wire clamp, ground connection naked copper flexible wire cable, earth terminal, earth clip etc.During installation or removal ground wire, between the insulating bar of wire clamp lower end and brake pull-rod, by three-jaw spring clip, connect, three-jaw spring clip is conductor, and coefficient of safety is low, if there is misoperation, easily sends out security incident.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of earth connection, has on transmission line when installing or removing ground wire, and brake pull-rod can be connected or depart from fast with wire clamp, makes operation safe, feature easily and efficiently.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of earth connection, comprises wire clamp and brake pull-rod with ground wire cable; In described wire clamp lower end, connect the insulating bar with endoporus, on the wall of insulating bar bottom, be provided with the vertical slotted eye being connected with the endoporus of insulating bar, in the upper end of described vertical slotted eye, be provided with the horizontal slotted eye being connected with the endoporus of insulating bar; Described brake pull-rod upper end is provided with T-shaped clutch bolt, and the endoporus of described T-shaped clutch bolt and insulating bar, vertical slotted eye and horizontal slotted eye are suitable.
The further improvement that the present invention is done is: also comprise ground connection band iron, described ground wire cable is connected between wire clamp and ground connection band iron.
The beneficial effect that adopts technique scheme to produce is: wire clamp of the present invention is connected with insulating bar by the T-shaped clutch bolt on brake pull-rod, and when ground wire is installed, wire clamp hangs on transmission pressure, and T-shaped clutch bolt and brake pull-rod can depart from very soon; When removing ground clamp, T-shaped clutch bolt and brake pull-rod can be combined as a whole very soon, and wire clamp is exited from transmission pressure; This earth connection handling safety, convenient and swift, can reduce labour intensity, raises labour efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
As shown in the figure: 1 ground connection band iron, 2 ground wire cables, 3 wire clamp, 4 insulating bars, 5 horizontal slotted eyes, 6 vertical slotted eyes, 7T type clutch bolt, 8 brake pull-rods.
Embodiment
Contrast Fig. 1 is used step to be described further to operation of the present invention:
An earth connection, comprises wire clamp 3 and brake pull-rod 8 with ground wire cable 2; In described wire clamp 3 lower ends, connect the insulating bar 4 with endoporus, on insulating bar 4 bottom walls, be provided with the vertical slotted eye 6 being connected with the endoporus of insulating bar 4, in the upper end of described vertical slotted eye 6, be provided with the horizontal slotted eye 5 being connected with the endoporus of insulating bar 4; Described brake pull-rod 8 upper ends are provided with T-shaped clutch bolt 7, and described T-shaped clutch bolt 7 is suitable with the endoporus of insulating bar 4, vertical slotted eye 6 and horizontal slotted eye 5.Also comprise ground connection band iron 1, described ground wire cable 2 is connected between wire clamp 3 and ground connection band iron 1.
Using method: when ground wire is installed, first go up push-and-pull restrictor bar 8 and makes brake pull-rod 8 and insulating bar 4 combinations by T-shaped clutch bolt 7, wire clamp 3 is clamped and rotated brake pull-rod 8 after transmission pressure and make T-shaped clutch bolt 7 exit vertical slotted eye 6 and insulating bar 4 disengagings; When removing ground wire, make the endoporus of the T-shaped clutch bolt 7 aligning insulating bars 4 on brake pull-rod 8, upper act and rotate brake pull-rod 8 make vertical slotted eye 6 and laterally slotted eye 5 block T-shaped clutch bolt 7, now insulating bar 4 connects 8 with brake pull-rod and is integrated, upper push-and-pull restrictor bar 8 drives wire clamp 3 to depart from transmission pressures.
