Abstract
The utility model discloses a 10kV insulation-piercing electricity-testing grounding ring. The 10kV insulation-piercing electricity-testing grounding ring includes an insulation-piercing wire clamp and an electricity-testing grounding ring; the electricity-testing grounding ring is a polygon grounding ring formed by a conductive rod; the insulation-piercing wire clamp includes a first clamping hole and a second clamping hole, wherein the first clamping hole is used for clamping a power transmission wire, and the second clamping hole is used for clamping the electricity-testing grounding ring; and the surface of the conductive rod arranged in the second clamping hole is coated with an insulating layer, and other parts of the conductive rod is exposed. The 10kV insulation-piercing electricity-testing grounding ring of the utility model has the advantages of simple structure, convenient installation, small contact area of the electricity-testing grounding ring, high contact quality, reduction of the work intensity of workers, reduction of power outage time and improvement of power supply reliability.
Description
Technical field
The utility model relates to electric equipment electrical verification, earthing device, especially a kind of 10kV insulating puncturing electricity testing grounding ring.
Background technology
(being 10kV and following electric pressure) generally all adopts aerial insulated wire to lay in the mid ﹠ low-voltage line of present urban distribution network; and when maintenance circuit or equipment; identify circuit for the security needs that guarantee the maintainer and hang the ground protection line after without electricity; this just requires, and earthing clamp must contact with electric wire reliably when hanging earthing conductor; and insulated wire can not be hung, so adopt electricity testing grounding ring.For many years, electrical verification before to the maintenance of 10 KV distribution transformer, hanging earthing conductor, because traditional electricity testing grounding ring exposed part of installing is vertical with the operating personnel present position, all need operating personnel to tilt than the electrical verification of wide-angle ability, hanging earthing conductor at bar, labour intensity is large, fail safe is unreliable.
The utility model content
In view of this, the purpose of this utility model provides a kind of 10kV insulating puncturing electricity testing grounding ring, solves electrical verification, hanging earthing conductor hard problem.
The purpose of this utility model is achieved through the following technical solutions:
A kind of 10kV insulating puncturing electricity testing grounding ring, comprise insulation puncture line clamping and electricity testing grounding ring, the polygon ground loop of described electricity testing grounding ring for being consisted of by contact rod, described insulation puncture line clamping comprises the first holes for clamping and the second holes for clamping, described the first holes for clamping is used for clamping power transmission line, described the second holes for clamping is used for clamping electricity testing grounding ring, and the contact rod surface that is arranged in the second holes for clamping is surrounded by insulating barrier, and the contact rod of other parts is exposed contact rod.
Further, described contact rod is copper rod.
Further, the cross-sectional area of described copper rod is 50mm
2-100mm
2
Further, also comprise insulation crust, the insulating puncturing electricity testing grounding ring is positioned at insulation crust.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy for installation, and the electricity testing grounding ring contact area is large, contact quality good, but decrease staff's working strength reduces interruption duration, improves power supply reliability.
Description of drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is insulating puncturing electricity testing grounding ring structure chart.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, a kind of 10kV insulating puncturing electricity testing grounding ring, comprise insulation puncture line clamping 1 and electricity testing grounding ring 2, the polygon ground loop of described electricity testing grounding ring 2 for being consisted of by contact rod, described insulation puncture line clamping 1 comprises the first holes for clamping 5 and the second holes for clamping 4, and described the first holes for clamping 5 is used for clamping power transmission line 3, and described the second holes for clamping 4 is used for clamping electricity testing grounding ring 2, the contact rod surface that is arranged in the second holes for clamping 4 is surrounded by insulating barrier, and the contact rod of other parts is exposed contact rod.Select polygon exposed ground loop can increase the area of contact, make the staff convenient when articulating earth connection, select the insulating barrier of the destruction insulated conductor that insulation puncture line clamping 1 can be the least possible, prolong the useful life of insulated conductor.
Present embodiment is chosen the good copper rod of conductance as contact rod, and the cross-sectional area of described copper rod is 50mm
2-100mm
2Can increase the ground loop contact area, improve contact quality.
As the improvement to present embodiment, the insulating puncturing electricity testing grounding ring also comprises insulation crust, and the insulating puncturing electricity testing grounding ring is positioned at insulation crust, so that whole device is effectively protected, improves the useful life of insulating puncturing electricity testing grounding ring.
Described electricity testing grounding ring 2 is trapezoidal or square, if be trapezoidal, the second holes for clamping of insulation puncture line clamping is used for clamping trapezoidal long limit.
Explanation is at last, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from the utility model claims limited range.
