Abstract
The utility model discloses a kind of all insulation puncture earthing device, have ambroin and ground connection aluminium ring, the outside of ground connection aluminium ring is arranged with the insulating cover with insulating effect, and insulating cover can open and close, and time closed, ground connection aluminium ring is closed therein; When opening, ground connection aluminium ring exposes in atmosphere, and, form acute angle or obtuse angle between the length direction of described ambroin and the length direction of ground connection aluminium ring.Advantage of the present utility model: after thrusting earthing clamp installation, closes weather-proof plastic insulation cover, and such ground connection aluminium ring is all under the protection of insulating cover; Danger Electric shock risk can be avoided; ground connection aluminium ring can also be made to avoid being oxidized in atmosphere, and useful life, order was longer, and reliability improves.When carrying out using grounding system, pull open insulating cover, ground connection aluminium ring can be exposed and ground connection hook carries out ground connection.
Description
Technical field
The utility model relates to electric equipment electrical verification, earthing device, is specifically related to a kind of all insulation puncture earthing device.
Background technology
In the mid & low-voltage line of current urban distribution network, (i.e. 10kV and following electric pressure) generally all adopts aerial insulated wire to lay; and when overhauling circuit or equipment; in order to ensure that the security needs of maintainer identify circuit without hanging ground protection line after electricity; this just requires that earthing clamp must contact reliably with electric wire when hanging earthing conductor; and insulated wire can not be hung, so adopt electricity testing grounding ring.
As shown in Figure 1, be in the Chinese patent of 201320272312.9 at application number, disclose a kind of 10kV insulating puncturing electricity testing grounding ring, comprise insulation puncture line clamping and electricity testing grounding ring, described electricity testing grounding ring is the polygon ground loop be made up of contact rod, described insulation puncture line clamping comprises the first holes for clamping and the second holes for clamping, described first holes for clamping is for clamping power transmission line, described second holes for clamping is for clamping electricity testing grounding ring, the contact rod surface being arranged in the second holes for clamping is surrounded by insulating barrier, and the contact rod of other parts is exposed contact rod.Its structure is simple, easy for installation, and electricity testing grounding ring contact area is large, contact quality good, significantly can reduce the working strength of staff, reduces interruption duration, improves power supply reliability.
But, existing like product, as shown in Figure 1, generally comprise insulation puncture line clamping 1, ground connection aluminium ring 3 and be enclosed within the insulating plastic layer 2 of ground connection aluminium ring 3 portion outboard, owing to will be connected with ground connection drag hook, therefore ground connection aluminium ring 3 is barish, therefore, all there is following shortcoming in this product:
1, ground connection aluminium ring 3 is outside exposed, easily causes oxidation, and contact resistance increases, and impact is connected with ground connection drag hook.
2, ground connection aluminium ring exposes and easily causes electric shock accidents dangerous.
3, when ground connection aluminium ring and ground connection drag hook are installed, be not easy to put in place, likely make ground connection drag hook touch ambroin 2 causes contact insufficient or affect its performance.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides one and can avoid ground connection aluminium epoxidised all insulation puncture earthing device.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of all insulation puncture earthing device, has ambroin and ground connection aluminium ring, it is characterized in that, the outside of described ground connection aluminium ring is arranged with the insulating cover with insulating effect, described insulating cover can open and close, and when described insulating cover closes, ground connection aluminium ring is closed therein; When described insulating cover is opened, ground connection aluminium ring exposes in atmosphere,
Further, acute angle or obtuse angle is formed between the length direction of described ambroin and the length direction of ground connection aluminium ring.
Further, described insulating cover is connected in hinged mode by bolt with one end of described ground connection aluminium ring.
Further, the described insulating cover draw ring that comprises weather-proof ambroin cover and be fixedly connected with described weather-proof ambroin cover one end.
Further, described draw ring is arranged on the position of close bolt on described weather-proof ambroin cover.
The beneficial effect that the utility model has:
After thrusting earthing clamp installation, closed by weather-proof plastic insulation cover, such ground connection aluminium ring, all under the protection of insulating cover, can avoid Danger Electric shock risk, and ground connection aluminium ring can also be made to avoid being oxidized in atmosphere, and useful life, order was longer, and reliability improves.When carrying out using grounding system, pull open insulating cover, ground connection aluminium ring can be exposed and ground connection hook carries out ground connection.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing all insulation puncture earthing device;
Structural representation when Fig. 2 is the utility model all insulation puncture earthing device inactive state;
Fig. 3 is the structural representation of the state of the insulating cover of Fig. 2 when opening completely.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
Shown in composition graphs 2, Fig. 3, a kind of all insulation puncture earthing device, has insulation puncture line clamping 1, ambroin 2, ground connection aluminium ring 3 and is set in the outside of ground connection aluminium ring 3 and has the insulating cover 4 of insulating effect.Insulating cover 4 can open and close, and when insulating cover 4 closes, ground connection aluminium ring 3 is closed therein, does not directly contact with air; When insulating cover 4 is opened, ground connection aluminium ring 3 exposes in atmosphere, also can be convenient to be connected with ground connection drag hook.
Insulating cover 4 is connected in hinged mode by bolt 6 with one end of ground connection aluminium ring 3, and namely insulating cover 4 rotates around bolt 6, achieves opening and closing.
The draw ring 7 that insulating cover 4 comprises weather-proof ambroin cover 5 and is fixedly connected with described weather-proof ambroin cover 5 one end.Pull with hand draw ring 7, insulating cover 4 can be opened and closed, and draw ring 7 is arranged on the position of close bolt 6 on weather-proof ambroin cover 5.Certainly, as long as draw ring 7 also can substitute with any device that other can realize insulating cover 4 opening and closing.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
