Abstract
The utility model discloses a lightning-protection electric-testing ground connector, which has functions of grounding, lightning protection and arc striking. The lightning-protection electric-testing ground connector comprises wire clamps, a connection bar, a grounding ring, an insulation protective cover and an arc striking device. One end of the connection bar is connected with the wire clamps, and the other end thereof is connected with the grounding ring. The insulation protective cover is covered outside the wire clamps. The arc striking device is arranged at one end of the grounding ring and is a circular projection. The circular projection is arranged on one side of the lower end of the grounding ring. The arc striking device can be an arc striking bar extending from the lower end of the grounding ring to the oblique direction or an arc striking bar extending from the lower end of the grounding ring to the horizontal direction. The lightning-protection electric-testing ground connector has functions of grounding electric testing and lightning protection, is convenient to mount, simple in structure and capable of protecting the wires from damage.
Description
Technical field
The utility model relates to the electrical verification earthing device of power distribution circuit, particularly relates to a kind of lightning protection electrical verification grounding device.
Background technology
Copper below the 10kV and aluminium insulated overhead line often need electrical verification and temporary grounding device when the maintenance construction, the electrical verification grounding device is a common tool.In addition, taken place by the situation of lightning-caused breaking for preventing insulated conductor, need flash guard be installed in the load-side of the post insulator of circuit, preserve from guardwire, existing electrical verification grounding device does not possess the function of striking lightning protection.
The utility model content
The purpose of the utility model is to provide a kind of lightning protection electrical verification grounding device that can possess the earthing and lightning protection function simultaneously.
For overcoming the defective of prior art; The technical scheme that the utility model adopts is: it comprises wire clamp firmware, pitman, ground loop, insulating shield, arc-initiating device; Pitman one end is connected with the wire clamp firmware; The other end is connected with ground loop, and it is outside that insulating shield is located at the wire clamp firmware, is provided with arc-initiating device in ground loop one side.
For making the striking effect better, as one of optimal way of the utility model, arc-initiating device is a circular protrusions, and circular protrusions is arranged on ground loop lower end one side.
The insulator that be to be fit to the different angles direction is as two of the optimal way of the utility model, the starting rod of arc-initiating device for extending to oblique lower direction from the ground loop lower end position.
The insulator that be to be fit to the different angles direction is as three of the optimal way of the utility model, the starting rod of arc-initiating device for extending to horizontal direction from the ground loop lower end position.
Compared with prior art, the advantage of the utility model is: the utility model has possessed the function of ground connection electrical verification, lightning protection simultaneously, simple installation, simple in structure, simple in circuits, and effectively guardwire is injury-free.
Description of drawings
Fig. 1 is the structural representation of one of the utility model execution mode;
Fig. 2 is two a structural representation of the utility model execution mode;
Fig. 3 is three a structural representation of the utility model execution mode;
Fig. 4 is the sketch map of installing and using of one of the utility model execution mode.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; The utility model mainly comprises wire clamp firmware 2, pitman 3, ground loop 4, insulating shield 1, circular protrusions 5; Pitman 3 one ends are connected with wire clamp firmware 2 bottoms; The other end is connected with ground loop 4 upper ends, and insulating shield 1 is located at the outside of wire clamp firmware 2, and circular protrusions 5 is arranged on ground loop 4 lower ends one side as arc-initiating device.Wire clamp firmware 2 is used for the clamping lead, prevents that lead from rocking, and insulating shield 1 is installed on the wire clamp firmware 2, plays the function of waterproof and insulation protection.As shown in Figure 2, arc-initiating device 5 can be the starting rod that extends to oblique lower direction from the ground loop lower end.As shown in Figure 3, arc-initiating device 5 can also be the starting rod that extends to horizontal direction from the ground loop lower end.As shown in Figure 4, the utility model is clamped on the lead 6, makes the following steel pin of its arc-initiating device 5 near insulator 7; When being struck by lightning; Flashover discharge between 7 times steel pin of arc-initiating device 5 and insulator, near the electric arc that continues discharge burning arc-initiating device 5 reaches avoids burning out with guardwire.
