For the operation of 66-220 kV power transmission line, it is generally necessary to conduct an electric inspection first, and then connect the grounding wire: first use the telescopic electroscope to inspect the electricity, and the operator installs the grounding end of the grounding wire on the pole tower, and then connects the grounding wire. Install the wire end of the grounding wire on the wire by means of outlet, throwing, hanging, etc. When the grounding wire is recovered after the operation, the grounding wire can only be pulled back by dragging, pulling, etc. This method will have considerable damage to the wire. Excessive wear and tear may cause wire breakage over time. These methods are time-consuming and labor-intensive, and pose a considerable threat to the safety of operators. the

Existing electroscopes can only perform electrical inspection alone, and the subsequent operation of connecting the ground wire also requires manual wiring or hanging and throwing installation. These two kinds of operations need to be carried out independently, the operation process is complicated, the labor intensity of the operators is increased, and the safety of the operators is reduced. the

Preferably, the electroscope is screwed to the telescopic rod. the

Preferably, the electroscope contact is configured as a clamp, connected to the electroscope as a rotating shaft, and the width of the electroscope contact is smaller than the width of the through hole at the wire end. the

Preferably, at the connection with the telescopic rod, the electroscope is provided with internal threads and external threads; the telescopic rod is provided with external threads. the

Preferably, the end of the telescopic rod is provided with an internal thread connected with an external thread of the electroscope. the

Compared with the prior art, the utility model has the advantage that the telescopic electroscope is used in conjunction with the ground wire, and after the electroscope, the wire end of the ground wire is installed on the wire by using the electroscope; the operation is completed Finally, use the electroscope and contacts to retrieve the lead end of the grounding wire, so as to reduce the working intensity, reduce the working time, improve the reliability of power supply, and improve the safety of operators. the

The utility model transforms the electric testing contact into a clamp shape, and uses the electric testing contact to hang the grounding wire at the through hole of the lead wire end to place the grounding wire during operation. The through hole of the clamp can make the grounding wire leave the working point, and the electric test contact acts as an auxiliary tool for the installation and removal of the wire end of the grounding wire. the

The use of telescopic insulating rods can extend enough length during use to carry out operations; it will not affect storage when it is usually retracted; in addition, this structure can also be used for the connection of other appliances that use insulating rods, only need to modify the connecting equipment. Can. the

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. the

An electroscope as shown in Figures 1, 2 and 3, including an electroscope contact 1, an electroscope 2, a telescopic rod 3 and a grounding device, the electroscope contact 1 is fixed on the upper end of the electroscope 2, and the electroscope The lower end of 2 is threaded on the telescopic rod 3; wherein the connecting end of the electroscope 2 and the telescopic rod 3 is set as a double thread structure: an internal thread and an external thread, the internal thread is connected with the external thread of the telescopic rod, and the external thread is connected with the telescopic rod Internally threaded connection at the end. The grounding device includes a ground wire 5 and a wire end 4 that can be connected to the operating point. The wire end 4 is set as a clamp, and an ear piece 41 that can be flexibly connected to the electric test contact is provided at the rear end of the clamp. There are through holes. the

As shown in Figure 2, the electroscope contact 1 is set in the shape of a clamp, connected to the electroscope 2 as a rotating shaft, and the width of the electroscope contact 1 is set to be smaller than the width of the through hole on the lug 41, which is convenient for the electroscope 1 clamp; at the same time, according to the position of the ear piece 41, the electric test contact 1 can be rotated to facilitate connection with the ear piece 41. Use the electric test contact 1 to directly clamp the operation point, and then the electric test operation can be carried out. After this operation and other follow-up operations are completed, the grounding operation can be performed only by clamping the wire end 41 to the operation point; after all operations are completed Finally, clamp the electric testing contact 1 to the two lugs 41 of the wire end 41 clamp, so that the wire end 41 clamp falls off, thereby assisting the installation and removal of the ground wire end 41 . the

Compared with today's electroscope and grounding wire, the product of the utility model needs to be operated step by step because the existing two products are operated separately. This product transforms the telescopic electroscope, and uses the electroscope to install the wire end of the grounding wire on the wire side, which can greatly reduce the time used when connecting the grounding wire, and reduce the time for operators to connect the grounding wire when going out. danger.
