Existing short-circuit grounding wire generally comprises wire clamp, earth lead and earth rod, and wherein the lower end of wire clamp is fixed on the upper end of earth rod by rivet, and the link of earth lead is welded on a side of wire clamp.This short-circuit grounding wire stable connection, intensity are high, are a kind of version the most common.
But, we know in each transformer station have different equipment, therefore in use, often need the wire clamp of different model and the earth lead of different model to mate different equipment, and the connected mode between each parts in existing this short-circuit grounding wire is unfavorable for repetition dismounting, causes restringing chuck and earth lead very inconvenient, and length consuming time, the prolongation of grid switching operation time and the prolongation of equipment interruption duration can be caused, simultaneously also may be accidents caused.Therefore, some transformer stations take to be equipped with many earth rods, and the method for every root earth rod being installed the wire clamp of different model and the earth lead of different model solves the problems referred to above, can find out, this solution cost is high, utilization rate of equipment and installations is low, and carry storage inconvenience, be unfavorable for management.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of composite type short-circuit grounding wire suit, and this suit can be combined into the short-circuit grounding wire of multiple band different model wire clamp and different model earth lead, and each parts stable connection, easy accessibility.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: composite type short-circuit grounding wire is set with, comprise the wire clamp of two or more different model, the earth lead of more than two different models, the earth rod of more than one and multiple wing bolt, the link of every root earth lead is equipped with conducting strip, described conducting strip has more than one through hole, one side of each wire clamp all has and described number of openings, the corresponding screwed hole in position, the lower end of each wire clamp all has a cylindricality connecting portion, the relative two sides of described cylindricality connecting portion are respectively equipped with a projection, the upper end of described earth rod has the tubular connecting portion that can hold described cylindricality connecting portion, a perpendicular spring put is provided with in the inner chamber of described tubular connecting portion, the relative both sides of described tubular connecting portion also have a concave shape groove, one end of described concave shape groove extends to the upper surface of described tubular connecting portion to form opening, the other end is closed.
Further, described composite type short-circuit grounding wire suit also comprises the wire clamp for placing two or more different model, the first-hand suitcase of multiple wing bolt and the second-hand's suitcase for the earth lead of placing more than two different models.
The beneficial effect of the utility model composite type short-circuit grounding wire suit is:
1. the utility model composite type short-circuit grounding wire suit can be combined into the short-circuit grounding wire of multiple band different model wire clamp and different model earth lead, thus the service requirements met distinct device, compared to existing technology, greatly reduce Equipments Setting quantity, and reduce cost, improve utilization rate of equipment and installations, and the utility model can when not needing by other instrument, complete the assembly and disassembly of short-circuit grounding wire quickly and easily, thus effectively shorten the operating time.
2. the utility model composite type short-circuit grounding wire suit can select suitable wire clamp and earth lead and earth rod to carry out assembled in situ by the height residing for the electric pressure of field apparatus, form and equipment, avoid the short-circuit grounding wire because configuring in transformer station cannot mate with field apparatus and need to change the time delay that short-circuit grounding wire brings, reducing equipment interruption duration.
