Abstract
The utility model relates to a strain earthed lightning-proof clamp device, which comprises a self-plug type strain clamp, a multiuse ring connected with the strain clamp and an insulated protective case covered outside the strain clamp, wherein the multiuse ring comprises an earthed ring and a starting rod extended from the earthed ring.
Description
[technical field]
The utility model relates to field of electrical equipment, relates in particular to the strain insulator ground connection lightning protection line clamping device in the overhead insulating distribution line.
[background technology]
Strain clamp is widely used in the overhead insulating distribution line, and its effect is that suspended insulated guide wire is fixed on the insulator of corner or terminal strain insulator bar, thereby aerial condutor is fixed or strained.In addition, also be provided with an insulating shield and strain clamp usually and be used, to play the effect of insulating protection.
Usually also an electricity testing grounding ring can be set in the overhead insulating distribution line, it can be used as the electrical verification and the temporary grounding device of suspended insulated guide wire when the maintenance construction.Above-mentioned strain clamp can with the ground loop global design, and insulating shield is directly injection-moulded on the wire clamp, plays waterproof effect.
Yet above-mentioned strain clamp and ground loop are provided with respectively, and not only construction and installation complexity, circuit is in disorder, construction cost is high, and the contact area of equipment and lead is big, easily damage wires.In addition, this set does not have lightning protection function, is easy to equipment is caused damage in the time of thunderbolt.
Therefore be necessary to design a kind of new strain insulator ground connection lightning protection line clamping device, to avoid above-mentioned defective.
[utility model content]
The purpose of this utility model is to provide a kind of aerial condutor strain insulator ground connection lightning protection line clamping device that can possess the earthing and lightning protection function simultaneously.
In order to reach aforementioned purpose, the related strain insulator ground connection lightning protection line clamping device of the utility model comprise from bolt type strain clamp, be connected from bolt type strain clamp many with ring and be located at insulating shield from the bolt type strain clamp outside, describedly manyly comprise ground loop and the starting rod that extends from ground loop with encircling.
Lower end at starting rod is equipped with earth connection.
Described ground loop is a frame shape structure.
Described starting rod is tilted to down from the lower position of ground loop and extends.
Described have the voussoir locking mechanism from bolt type strain clamp.
Many with the outer setting of encircling the insulating barrier made from organic composite material.
Compared with prior art, advantage of the present utility model is: strain insulator ground connection lightning protection line clamping device of the present utility model has possessed the function of clamp, ground connection, lightning protection simultaneously, and is little without simple installation, lead contact area, and simple in circuits.
[description of drawings]
Fig. 1 is the floor map of the utility model strain insulator ground connection lightning protection line clamping device.
[embodiment]
See also Fig. 1, a kind of execution mode of the strain insulator ground connection lightning protection line clamping device that the utility model is designed comprise from bolt type strain clamp 1, be connected from bolt type strain clamp many with ring 2 and be located at insulating shield (not shown) from bolt type strain clamp 1 outside.
Described have the voussoir locking mechanism from bolt type strain clamp 1, can pass and lock lead for built on stilts insulated conductor.Should have characteristics such as simple installation is reliable, the circular arc large tracts of land is held tightly, grip is big, the difficult wriggling of lead, no electric energy loss from bolt type strain clamp 1.In the present embodiment, select for use non magnetic high-strength, antioxidant aluminum alloy materials to make from bolt type strain clamp.
How to comprise ground loop 20 and the starting rod 22 that extends from ground loop downwards with ring 2.Described ground loop 20 is a frame shape structure greatly most, its upper end be connected from bolt type strain clamp 1, described starting rod 22 is tilted to down extension and forms from the lower end of ground loop 20.In many outsides with ring 2, be provided with the insulating barrier made from organic composite material, can improve its insulation property.
At the about 15-20mm in the lower end of starting rod 22 place, the earth connection (not shown) is installed, when thunderbolt took place, starting rod 22 caused electric arc on the earth connection and discharges.Thereby the protection insulated conductor is injury-free.In addition, in non-high minefield, also earth connection can be set, even be struck by lightning once in a while, the electric arc of the generation of being struck by lightning also can be protected insulated conductor in roomy discharging from bolt type strain clamp and use between the ring more.
Insulating shield is located at from the outside of bolt type strain clamp 1, and it adopts organic material to make, and has good insulation performance performance, ageing resistace and flame-retardant energy, can play the good insulation performance protective effect.
In sum, strain insulator ground connection lightning protection line clamping device of the present utility model has possessed the function of clamp, ground connection, lightning protection simultaneously, and is little without simple installation, lead contact area, and simple in circuits, is convenient to install other electric components.
