The utility model adopts a pincer chuck. When working, set the test lead wire on the wire insertion hole of the thin rod, and then press the lower jaw of the pincer chuck through the pressure equalizing ring of the lightning arrester, so that the terminal rod clamps or loosens the lightning arrester. pressure ring. The wiring mode of the utility model replaces the wiring mode of bucket arm truck and manpower cooperation, and the wiring time is 1 minute, which greatly shortens the wiring time and improves the work efficiency.

Description

Terminal rods for lightning arresters

technical field

The utility model relates to an electric appliance, in particular to a connecting rod used for a lightning arrester. the

Background technique

110kV and above surge arresters with grading rings are outdoor equipment. This type of arrester is generally placed at a relatively high position. When conducting high-voltage tests on arresters, it often takes a lot of time, manpower and material resources, which reduces work efficiency. When encountering windy weather, the test leads are often scraped off, which brings great safety hazards to test personnel and equipment. the

At present, the method of hanging the test lead wire on the pressure grading ring of the arrester is used to carry out the high-voltage test wiring, and the following shortcomings are found in actual work:

1. The voltage equalizing ring of the surge arrester is placed at a high position, and it is inconvenient to connect the test lead wires, so it needs to be completed by means of a bucket arm truck. the

2. The bucket arm truck occupies a large area and has a long arm, so it is difficult to maintain a sufficient safety distance from the live equipment. the

3. It takes a long time to operate the bucket arm truck, and the personnel involved in monitoring, commanding, and operating etc. invest a lot. the

4. The test leads connected to the pressure grading ring of the arrester are easily affected by external forces. In windy weather, the test leads are easily scraped off, which seriously threatens the safety of test personnel. the

The existing test lead wires are inconvenient to hang, and the connection is not firm, which brings inconvenience to the test process, affects the test data, is easily affected by the outside world, and seriously threatens the safety of people and equipment. the

Utility model content

The technical problem to be solved by the utility model is to provide a simple structure, convenient installation, beneficial to test wiring, not easy to damage, safe and reliable wiring rod used for lightning arresters. the

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A terminal rod for a lightning arrester, comprising a rod body, a rod body fixed on the top of the rod body, a pliers-shaped chuck arranged on one side of the rod body, and a thin rod, and one end of the thin rod is provided with a wire insertion hole , the other end of the thin rod is threadedly connected to the rod body, and the thin rod and the pincer chuck on the rod body are opposite to each other; the lower jaw of the pincer chuck is longer than the upper jaw, and the overall shape of the pincer chuck is C shape. the

Preferably, the rod body is fixedly mounted on the top end of the rod body through screw connection. the

The utility model adopts a pincer chuck. When working, set the test lead wire on the wire insertion hole of the thin rod, and then press the lower jaw of the pincer chuck through the pressure equalizing ring of the arrester, so that the terminal rod clamps or loosens the arrester. pressure ring. The wiring mode of the utility model replaces the wiring mode of bucket arm truck and manpower cooperation, and the wiring time is 1 minute, which greatly shortens the wiring time and improves the work efficiency. the

The utility model has the advantages of being rust-resistant, wind-proof, simple in structure, easy to install, not easy to damage, and easy to carry, and can further improve test reliability and safety. Due to its simple structure and convenient operation, it can reduce vehicle investment and labor workload, and improve work efficiency. the

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Can know from the utility model embodiment shown in Fig. 1:

A terminal rod for a lightning arrester, comprising a rod body 1, a rod body 2 fixedly mounted on the top of the rod body 1 through threaded connection, a pincer chuck 3 arranged on one side of the rod body 2, a thin rod 4, and one end of the thin rod 4 is provided There is a wire hole, the other end of the thin rod 4 is threadedly connected with the rod body 2, and the thin rod 4 on the rod body 2 and the pincer chuck 3 are opposite to each other; the lower jaw of the pincer chuck 3 is longer than the upper jaw, This pliers chuck 3 is C-shaped as a whole. the

The utility model adopts the pincer chuck 3. When working, set the test lead wire on the wire insertion hole of the thin rod 4, and then press the lower jaw of the pincer chuck 3 through the pressure equalizing ring of the arrester, so that the connecting rod is clamped or loosened. Open the voltage equalizing ring of the arrester. The wiring mode of the utility model replaces the wiring mode of bucket arm truck and manpower cooperation, and the wiring time is 1 minute, which greatly shortens the wiring time and improves the working efficiency. the

In summary, the content of the present utility model is not limited to the above-mentioned embodiments, and those skilled in the art can easily propose other implementations according to the guiding principles of the present utility model, and these implementations are all included in the scope of the present utility model Inside. the
