What the utility model was brought has the beneficial effect that：Compared with prior art, the utility model makes traditional short circuit grounding
Line possesses and has electricity prompting and blocking function, and when operating personnel hang the ground wire to when having electric equipment, ground wire top is detected
Mechanism action, after testing agency's action, due to the electrical potential difference between ground wire and charging equipment, equipment will be to insulation shell top
Electrode discharge, form obvious electric arc and frizzle, play the effect of obvious prompt alarm, remind operating personnel's equipment to have
Electricity, must off-ground operation immediately；
Due to the metering function of impedor, make the arc current very little for flowing through it, arc short-circuit will not be caused, if
Operating personnel continue operate by force, due to the arc current by electrode, impedor, coil, be grounded into ground, will not to behaviour
Damaged as personnel, after coil electricity can excitation immediately, be additionally, since compressor arm and be made up of ferrous material, greatly lifted
The magnetic of coil, under the attraction of coil, clamp barb and be attracted and is contacted with compressor arm, now operating personnel can not continue handle
Ground wire is put into conductor grip, serves the effect of forced blocking, fundamentally avoids pernicious thing caused by hanging earthing conductor by mistake
Therefore.
