Shorting stub, its one end is connected with copper bar clip, and the other end is connected with connector.
The present invention compared with prior art, has the following advantages:
The present invention have use flexibility high, volume is little, lightweight, outward appearance is exquisite, simple to operate, quick lock in, safe and reliable feature.
Accompanying drawing explanation
Fig. 1 is the parts explosion of a kind of cranking test general-purpose combination of the present invention short-circuit device;
Fig. 2 is a kind of cranking test general-purpose combination of the present invention short-circuit device overall structure figure.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, a kind of cranking test general-purpose combination short-circuit device, comprises: earthing bar parts, 3 phase line copper bar parts and connector 2; Described earthing bar parts are connected with 3 phase line copper bar parts respectively by connector.The earth connection 12 that described earthing bar parts comprise earthing bar clip 11 and are connected with earthing bar clip 11.Described connector 2 one end is provided with earth connection connecting hole 21.Described earth connection 12 is inserted in earth connection connecting hole 21.
Each described phase line copper bar parts comprise: copper bar clip 31; Shorting stub 32, its one end is connected with copper bar clip 32, and the other end is connected with connector 2.
Please refer to Fig. 2, when the present invention carries out big current field experiment, earth connection 12 is inserted in earth connection connecting hole 21, earthing bar clip 11 is clipped on the grounding contact in switch storehouse, 3 corresponding 3 phases of copper bar clip 31,3 copper bar clips 31 are clipped on the 3 phase contacts in switch storehouse, thus complete the short circuit of 3 phase contacts and grounding contact.
In sum, a kind of cranking test general-purpose combination of the present invention short-circuit device, has and uses that flexibility is high, volume is little, lightweight, outward appearance is exquisite, simple to operate, quick lock in, safe and reliable feature.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
