Description

Prevent the grounding wire device of charged hanging earthing conductor

Technical field

The utility model belongs to the improvement of grounding wire device structure, particularly prevents the grounding wire device of charged hanging earthing conductor.

Background technology

Now use traditional earth connection, the ground connection hook and the insulating bar of its conductor part are an indivisible integral body.(serviceability itself do not need insulating bar except), earth connection is to can not determine whether the equipment that will install has voltage when installing, thereby before installing, must use electroscope to advance to use electrical verification, only after determining the true no-voltage of being installed of equipment, just fill and permitted to install earth connection, the operating personnel that have in practical operation follow the line of least resistance and dislike trouble, can not strictness follow operating instructions, just often define no-voltage with oneself subjective judgement, skip the electrical verification program and directly install the operation of earth connection, like this in case go to the wrong way at interval or because other various reasons causes installed equipment to have voltage, will cause the generation of the pernicious misoperation fault of charged hanging earthing conductor, work the mischief for life and equipment, and have influence on the safe operation of electrical network.

The utility model content

The purpose of this utility model is to provide a kind of grounding wire device that prevents charged hanging earthing conductor, it is rational in infrastructure, combined by electroscope and grounding wire device, substitute the insulation hook stick in traditional earth connection, finish the installing earth connection jointly, reach the effect that electric early warning is arranged simultaneously, thereby prevent the generation of the pernicious misoperation fault that charged hanging earthing conductor brings with closing the ground lock.

The purpose of this utility model is achieved in that a kind of grounding wire device that prevents charged hanging earthing conductor, comprise the ground connection hook and the electroscope that have lead-in wire and wire clamp, at ground connection hook root the connection pipe box is being set, connect pipe box and match by the external screw thread that is provided with on the internal thread that is provided with on its inner tubal wall and the pitman head periphery tube wall, pitman one end stretches into the tube connector casing cavity with ground connection conductive hook and pitman Joint; Pitman matches by the internal thread that is provided with on the external screw thread that is provided with on its afterbody periphery wall and the tube connector head internal perisporium, and the tube connector tube chamber is stretched in the pitman bottom, with pitman and tube connector Joint, cooperates in the tube connector tube chamber middle part electroscope is installed; The external screw thread that is provided with on the internal thread that Zhou Guanbi is provided with in the tube connector afterbody and the ground connection holding rod head end perisporium matches, and the ground connection holding rod stretches into tube connector afterbody tube chamber, and tube connector is fixed on the ground connection holding rod head end; Electroscope matches by lead with the ground connection hook and is connected.

The utility model operating principle is: in the process that the ground connection of installing earth connection is linked up with, ground connection hook with by the distance of installing conductor by as far as closely, connect until the zero distance contact, also more and more nearer with the conductor distance of installing earth connection thereupon with the electroscope in the electroscope that ground connection hook is connected, like this, when the conductor of installing earth connection has voltage, electrical verification signal generator in the electroscope can be sensed the electric field signal that energized conductor produces by the conductive pitman and the ground connection hook that are connected with it, the electrical verification signal generator is produced reports to the police, thereby make the operating personnel of installing earth connection no longer the ground connection hook be installed conductor near quilt, reach electric early warning is arranged, stop the behavior of misoperation, simultaneously can make operating personnel in time correct act of violating regulations again, come back in the normal procedure of electrical verification, to have found out electric reason.The utility model is rational in infrastructure, easy and simple to handle, it is with the insulating bar cancellation of traditional earth connection, make new earth connection insulating bar not arranged, the substitute is galvanoscopic insulating bar, the mechanical strength of galvanoscopic insulating bar is improved, make the requirement of the mechanical strength that can only satisfy the operation of mounting or dismounting earth connection, and install the operating function part additional at galvanoscopic head, and make to be merely able to match with the ground connection hook, connect the operation of finishing the mounting or dismounting earth connection, will make operating personnel's electrical verification by force when installing earth connection like this, reaching has electric early warning, stops the purpose of installing operation, thereby has prevented the generation of the pernicious misoperation fault of charged hanging ground-wire.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is looked the sectional structure schematic diagram for the utility model master.

Embodiment

A kind of grounding wire device that prevents charged hanging earthing conductor, as shown in drawings, comprise the ground connection hook 1 and the electroscope 8 that have lead-in wire and wire clamp 14, link up with 1 root ground connection connection pipe box 13 is being set, connecting pipe box 13 matches by the external screw thread 4 that is provided with on the internal thread that is provided with on its inner tubal wall and the pitman 5 head periphery tube walls, pitman 5 one ends stretch into and connect pipe box 13 tube chambers, with ground connection conductive hook 1 and pitman 5 Joints; Pitman 5 matches by the internal thread that is provided with on the external screw thread 6 that is provided with on its afterbody periphery wall and tube connector head 7 internal perisporiums, the tube connector tube chamber is stretched in pitman 5 bottoms, with pitman 5 and tube connector Joint, cooperate in the tube connector tube chamber middle part electroscope 8 is installed; The external screw thread 10 that is provided with on the internal thread that Zhou Guanbi are provided with in the tube connector afterbody 9 and the ground connection holding rod 11 head end perisporiums matches, and ground connection holding rod 11 stretches into tube connector afterbody tube chamber, and tube connector is fixed on ground connection holding rod 11 head ends; Electroscope 8 and ground connection hook 1 matches by lead and is connected.

Connect the screw 2 that is provided with on pipe box 13 tube walls and be connected cooperation with the screw flight of wing bolt 3, the screw end head of wing bolt 3 stretches into and connects pipe box 13 tube chambers, cooperate roof pressure on the externally threaded periphery wall of being provided with of pitman 5, wing bolt 3 can be used for fixedly being wound in the conduction copper cash on its screw rod.The blind hole that is provided with on pitman 5 barred bodies with internal thread with stretch into wherein screw rod 12 and be threaded and cooperate.
