Description

Portable piercing short-circuit grounding wire
Technical field
The utility model relates to the structure technology in power industry maintenance technology field, particularly a kind of portable grounding wires.
Background technology
For improving reliability and the fail safe of power supply, high and low pressure insulated conductor is just used more and more widely, but the insulated conductor section construction of fixed grounding wire clamp be not installed, in order the insulated conductor short circuit grounding of fixed grounding wire clamp not to be installed, current way is: first, staff's ascend operation removes the insulating barrier of insulated conductor with peel manually; Then, divesting on the plain conductor of insulating barrier after electrical verification, then the plain conductor that divests insulating barrier is being clamped in by between earth terminal and wireplint, to complete short-circuit grounding wire.
The consequence of this operation is: the one, destroyed the insulating barrier of wire, and left hidden danger to insulated conductor safe and stable operation from now on; The 2nd, unofficial whether true no-voltage wire insulation when peel manually removes, has brought serious hidden danger to staff's personal safety.Therefore, existing earth connection, does not have short circuit grounding performance to high and low pressure insulated conductor, does not reach the object of protection workmen life security.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, handled easily, portable piercing short-circuit grounding wire that fail safe is good.
The utility model comprises that upper end arranges the insulating bar of screw mandrel, the screw mandrel of insulating bar is threaded with the underarm that is provided with the earth terminal of tiger's jaw, one wireplint is set in the tiger's jaw of described earth terminal, the lower end of described wireplint is connected with the screw mandrel upper end in being inserted into tiger's jaw, it is characterized in that being fixedly installed the downward upper puncture needle of needle point on the described earth terminal surface towards wireplint, towards on the wireplint upper surface of puncture needle be fixedly installed the lower puncture needle that needle point makes progress.
When carrying out wire grounding connection, without the insulating barrier divesting in advance outside wire, and only need carry out two step operations: first, use electroscope to measure, prove the true no-voltage of the equipment that will overhaul on portable piercing electrical verification wire clamp; Then, the equipment short circuit grounding that should use rapidly portable piercing short-circuit grounding wire to overhaul, be about to directly be inserted in tiger's jaw with the wire of complete insulating barrier, by rotating insulated bar, tighten up tiger's jaw, wire clamp is held in tiger's jaw, owing to being provided with puncture needle, when tightening up tiger's jaw, upper and lower puncture needle is through insulating barrier, make the conductor dbus wherein cross upper and lower puncture needle and wireplint and earth terminal conducting, just completed the object of using the equipment short circuit grounding that the utility model will overhaul rapidly.
The utility model utilizes the insulating barrier of upper and lower lancet puncture wire, and the metal part that makes insulated conductor therewith earthing clamp connects, and reaches the object that repair apparatus can short circuit grounding.The utility model is simple and reasonable for structure, convenient and swift operation, and short circuit grounding performance is good.
In order to match with the wire that is mostly circular cross-section, the lower surface of the upper arm of described earth terminal and the upper surface of wireplint arrange respectively cambered surface.
For convenient, produce and repacking, described upper puncture needle is fixedly installed on an arc, and described arc is bolted on earth terminal.
Also can on earth terminal, offer through hole, the other end set bolt of arc, described bolt is set in through hole, and the nut that is threaded in through hole upper end is fixed strengthening.
For convenient, produce, install and use, also make the interlock of screw mandrel and wireplint, lower puncture needle improve, the utility model is also offered stepped hole at described wireplint center, the epimere internal diameter of described stepped hole is greater than hypomere internal diameter, described lower puncture needle is nested with in stepped hole by the needle handle coordinating with described stepped hole, and the needle handle lower end of described lower puncture needle is connected with the wire rod thread that is arranged on wireplint below.
