Abstract
The utility model relates to a portable short circuit grounding device. The transformer district ground wire comprises two pincer-like wire clamps that are hinged at middle parts, wherein the tail of each wire clamp is provided with a handle, and the head of each wire clamp is provided with grooves. The transformer district ground wire has the characteristics of safety, convenience, and reliability in usage.
Description
Technical field
The utility model relates to a kind of pocket short circuit grounding apparatus.
Background technology
In the prior art; The short circuit grounding apparatus of pocket generally uses the short circuit earth rod; The major defect of its existence is: 1, can only on the low-voltage insulation lead, ground loop be installed earlier; Then, so not only increased workload and cost of investment, but also destroyed the performance of insulated conductor at suspension low pressure earth connection.2 if low-voltage cable is had no way of handling especially and is hung the low pressure earth connection, can only assign a workmen to guard to the switch place, has avoided people's mistake to run the pass jointly.If 3 on downtown roads ground, be difficult to find the ground stud insert division.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned defective of prior art, and a kind of safe in utilization, convenient, reliable platform district earth connection is provided.
The utility model comprises two Pincerlike cable clamps that the middle part is hinged, and the afterbody of wire clamp is provided with handle, and the head of wire clamp is provided with groove.
The further technical solution of the utility model is that the groove on described two wire clamps is symmetrically set, and the groove on a wire clamp is several, and one of them groove is square, and a groove is a circular arc.
Adopt the platform district earth connection of said structure to have following advantage: 1, " platform district earth connection " need pile crown under switch hangs and gets final product, and need not step on bar, has also reduced the work of high aerial transmission earth connection simultaneously.Whether 2, " platform district earth connection " wire clamp adopts the tong-like pattern, makes crimping reliable, be convenient to inspection and contact with copper bar and put in place.Ground connection is taked square toes wire clamp pattern ground connection, makes ground connection more reliable.Reduce simultaneously because high aerial when transmitting earth connection, transmit contacting and destruction between rope and the earth connection.3, " platform district earth connection " avoided original " short circuit earth rod " big and heavy shortcoming, 1/2nd of its shortage in weight " short circuit earth rod " weight." platform district earth connection " adopts handheld versions, and be easy to carry, the phenomenon of difficult elephant the " short circuit earth rod " insulating bar fracture in transportation.Because there is earth electrode in " short circuit earth rod ", its easily and earth connection and insulating bar touch and breakoff phenomenon take place.4, " short circuit earth rod " needs the operating personnel to carry out work high above the ground, and this just makes the operating personnel all the time within this dangerous spot is fallen in the high-altitude.And in case in the process of electrical verification, get an electric shock, or hang earth connection the time get an electric shock, can make the power supply of breaking away from that operating personnel's very first time can not instinct equally.Even broken away from power supply, can not implement the first aid of getting an electric shock rapidly, this has just delayed the quality time of first aid." platform district earth connection " reduced the danger of pole-climbing ascend operation, the phenomenon that does not exist the high-altitude to fall; In a single day get an electric shock simultaneously, also can break away from according to operating environment instantaneous time at that time.5, reduce interruption duration, improve power supply reliability.Do not need pole-climbing, high-altitude electrical verification, high-altitude to transmit earth connection, aerial suspension earth connection, high-altitude dismantling earth connection or the like just because of " platform district earth connection ", the activity duration is significantly reduced, shortened the time that has a power failure.6, grounded part adopts it is clipped on the ground connection band iron of distribute-electricity transformer district, can avoid like this since geology can't ground connection possibility.
Description of drawings
Further illustrate the particular content of the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1: the structural representation of present embodiment.
Embodiment
As shown in the figure, present embodiment comprises two Pincerlike cable clamps 1 that the middle part is hinged, and the afterbody of wire clamp 1 is provided with handle 2, and the head of wire clamp 1 is provided with groove 11,12.Groove 11,12 on described two wire clamps 1 is symmetrically set, and the groove on a wire clamp has two, and one of them groove 11 is square, and a groove 12 is a circular arc.
Claims (3)
1. a platform district earth connection comprises two Pincerlike cable clamps that the middle part is hinged, and the afterbody of wire clamp is provided with handle, and the head of wire clamp is provided with groove.
2. according to claim 1 district's earth connection, it is characterized in that: the groove on described two wire clamps is symmetrically set.
3. according to claim 2 district's earth connection is characterized in that: the groove on a wire clamp is several, and wherein at least one groove is square, and at least one groove is a circular arc.
