At.In use, being series at fuse by protection circuit, when being more than specified value by the electric current of protection circuit, and by certain
After time, the heat fusing melt generated by melt itself disconnects circuit, to play the role of protection.
Currently, the lookup for 10kV line-to-ground fault, or graded insulation is carried out to route using 2500V megameter
Resistance measurement substantially determines line fault range.Its working principle: megameter passes through the route or equipment that have been substantially discharged
Connection " L ", " E ", " G " three wiring piles Hi-pot test Line To Line road pressurizeed to measure its insulating resistance value.
The operating risk of this measurement insulating resistance value is larger, and route is without the interim three-phase ground line of installing, especially thunderstorm
When season, insulation measurement is carried out to faulty line or equipment, route is easy to produce induction incoming call, and operating personnel can not take precautions against
There is the possibility that person electric shock can occur in the danger for incuding incoming call.
Summary of the invention
The present invention is directed to solve above-mentioned technical problem at least to a certain extent, Hi-pot test line wire clamp is provided, prevents million
During Europe table measures insulation resistance, induction incoming call injures operator.
The technical scheme is that Hi-pot test line wire clamp, including conducting wire, the wire clamp being connect with conducting wire, wherein also wrap
Device for fusing is included, device for fusing is connected on conducting wire, and conducting wire connects megameter.
In the present invention, by being arranged device for fusing in Hi-pot test line wire clamp lower part, when test line or equipment have
When induction incoming call, fuse can fuse immediately, disconnect the connection with megameter, prevent induction incoming call along Hi-pot test line, wound
Evil arrives megameter operator.The Hi-pot test line wire clamp is detachable, if having fuse or wire clamp damage, can be replaced in time.
Further, the wire clamp includes insulation division and conductive clamp, and conductive clamp is fixed in the insulation division side,
Other side connecting wire.
In the present invention, insulation division can prevent operating personnel's electric shock using the material such as rubber etc. of insulation.Conductive clamp is direct
Clamp test line.
Further, the insulation division includes insulation division main body, connection handle portion, effect handle portion, the insulation
Portion's body side is fixedly connected with conductive clamp, other side fixed function handle portion and connection handle portion；
The connection handle portion connecting wire, effect handle portion are vacantly arranged.
In the present invention, insulation division main body is main component, and conductive clamp can be inserted into the inside of insulation division main body, thus with
Conducting wire connection.Connection handle portion is columnar structure, is coated on outside conducting wire, plays the function of insulation.Act on handle portion to
Outer extension, can be with the hand contact action of human body.
In use, the thumb press of human body is in connection handle portion or effect handle portion, in addition 4 finger pressings act on hand
On shank or connection handle portion, so that clip be made to open or close, test line is clamped.
Further, the angle between the axis of the connection handle portion and the axis for acting on handle portion is 30 degree -60
Degree.Above-mentioned angle setting rationally, meets the hand profile of human body.
Further, sawtooth is additionally provided on the conductive clamp.Sawtooth can increasing friction force, to preferably be pressed from both sides
It holds.
Further, the material of the conductive clamp is metal.Conductive effect can be just played in this way.
Compared with prior art, beneficial effect is: during the present invention prevents measurement insulation resistance by megger, induction incoming call
Operator is injured.A kind of protection is also formed to measuring devices such as megameters.
Detailed description of the invention
Fig. 1 is overall structure of the present invention.
Specific embodiment
