Abstract
The utility model relates to a ground wire operating lever, belonging to the commonly used tool in the electric power system, which essentially consists of a lead clamp and an insulation pole; one end of the lead clamp is provided with a connector which has a connecting terminal, the lead clamp and the insulation pole realize solid connection by use of the connecting head, and the outer surface of the insulation pole is provided with a light coating. The utility model is used for the line operations of maintenance, hanging and ground wiring, which reduces the phenomena that the ground cable often drop to the line, thereby avoiding the serious maloperation accident of the ground cable knife brake.
Description
Technical field
The utility model designs a kind of earth connection action bars, belongs to the electric power system common tool.
Background technology
In the electric power system construction, particularly in the maintenance of high-tension electricity conveying circuit, often need the ground connection operation, often the instrument that uses is the earth connection action bars.Its method of operation is the main power source that stops this working line earlier, then with electroscope identify really do not have electricity after, hang the sealing-in ground wire again, to guarantee this line construction personnel's safety.Yet, in real work, often occur earth connection drop phenomenon on the line, especially when carrying on construction work at night, because working line is longer, be difficult to make uniform and hang the earth connection of envelope, still have earth connection to lose when causing this circuit to send electricity and hang on the circuit, the generation that causes the band ground wire to close the serious misoperation fault of disconnecting link.
Summary of the invention
The purpose of this utility model is to provide a kind of earth connection action bars, is used for the earth connection operation, has avoided earth connection drop phenomenon on the line.
The purpose of this utility model realizes in the following manner.The earth connection action bars mainly is made up of lead dop and insulating bar, and the lead dop is a metal material, and the end is provided with connector, is provided with binding post above, and the lead dop is fastenedly connected by connector and insulating bar, at the extexine of insulating bar luminescent coating is arranged.
No matter by day or night the utility model compared with prior art has following technological progress:, the faint fluorescence that insulating bar sends can point out people to also have the earth connection of the envelope of hanging on which bar circuit, reduce the generation of misoperation fault, alleviated the work difficulty of construction simultaneously.
Description of drawings
What Fig. 1 provided is structural representation of the present utility model.
The implication of each label representative is as follows among the figure:
1, lead dop 2, two tongue piece 3, making leaf spring 4, connector 5, binding post 6, insulating bar 7, luminescent coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.The earth connection action bars of the present utility model that provides referring to accompanying drawing 1, in its upper end is lead dop 1, be made with metal material, the centre of lead dop 1 is two tongue pieces 2 of card line, the 3rd, the elastic pressuring spring sheet, be useful on the connector 4 that links to each other with insulating bar 6 in the lower end of lead dop, be provided with binding post 5 on connector 4, the extexine of insulating bar 6 has luminescent coating 7.
Luminescent coating 7 is a fluorescent material layer, and its principle is that fluorescent material can reflect faint light beam, can make action bars reflect very bright refract light, after work is finished, when checking circuit, be very easy to find drop earth connection on the line, generally its reflective life-span is about 5 years.
In addition, luminescent coating 7 can also be the noctilucence coating of energy storage.Its operation principle is, Noctilucent material absorbs heat energy by day, and can send light night.
Luminescent coating performance that these two kinds of materials make and the designing requirement that can both satisfy action bars useful life.Manufacture craft is simple, is fit to suitability for industrialized production.
The withstand voltage properties of earth connection action bars, humidity resistance and mechanical distortion and tensile property all comply with relevant regulations.
