Description

Telescopic high-altitude test connector

technical field

The invention belongs to the technical field of electrical testing, in particular to a device for working at heights.

Background technique

At present, the high-altitude test wiring generally uses insulated bucket trucks or artificial climbing wiring, which not only has a greater risk of high-altitude operations, but also insulated bucket trucks are limited by the site. The traditional high-altitude test connectors are all in the form of external wires. During the test, the current terminal and the voltage terminal of the test clamp are connected to the current test line (cross-sectional area up to 10mm ² ) and the voltage test line respectively, and then clamp it to the equipment under test. Terminals. Taking a 220 kV circuit breaker as an example, the height is generally 8 meters. Due to the self-weight of the attached line, the pole lifter bears a lot of gravity. More than two people are required to lift the test pole, and the test pole sometimes breaks. And it is easy to dump and accidentally touch the adjacent charged intervals, and the work safety is reduced. In addition, the winding work before and after the test is cumbersome and inefficient.

Contents of the invention

In order to solve the problem of operation risk in artificial climbing wiring, the following technical solutions are proposed.

A telescopic high-altitude test connector, its special feature is to install wiring pliers on the top of the telescopic insulating rod, the test line passes through the insulating rod and then connects to the wiring pliers, and the bottom of the telescopic insulating rod is fixed on the winding box On the top, a winding reel is installed in the winding box, the lower end of the test line is wound on the winding reel, and leads to the terminal connected to the test instrument, and a winding handle is provided on the winding reel.

The so-called insulating rod is tubular, and the middle is empty, and the test line can pass therethrough.

When using the telescopic high-altitude test wiring connector for wiring, place it directly below the terminal of the equipment under test, pull the telescopic insulating rod upwards, and drive the test wires wound on the winding reel, when the height is sufficient, put the wiring pliers Clamp the terminal of the equipment under test, and connect the bottom end of the test line to the test instrument for testing. After the test is completed, disconnect the test line from the test instrument, loosen the clamp, retract the telescopic insulating rod, and wind the test line on the winding reel at the same time.

The present invention has the following advantages

The telescopic high-altitude test connector effectively solves the disadvantages of the traditional high-altitude connector. When wiring, by stretching and retracting the telescopic insulating rod, the telescopic form of straight up and down is adopted to improve the wiring method of the traditional high-altitude connector after connecting 4-5 insulating rods and lifting them horizontally, eliminating the possibility of touching the adjacent electrified by lifting the rod horizontally interval security risk. The test line is wound on the winding shaft, which reduces the tedious work burden of winding the line before and after the test, and can be easily operated by one person, which not only ensures safety, but also improves work efficiency.

Detailed ways

Example

A telescopic high-altitude test connector, which is to install a wiring clamp 1 on the top of a tubular telescopic insulating rod 2, a test line 3 passes through the insulating rod 2 and is connected to the wiring clamp 1, and the bottom of the telescopic insulating rod 2 is fixed On the winding box 7, a winding reel 4 is housed in the winding box 7, and the lower end of the test line 3 is wound on the winding reel 4, and the connecting terminal 6 connected to the testing instrument is drawn out. Wire handle5.

When in use, fix the base and winding box 7 below the terminal of the equipment under test, connect the upper part of the test line 3 to the wiring pliers 1 on the top of the telescopic insulating rod 2, and pull the telescopic insulating rod 2 upward to drive its internal test line 3 And winding disc 4 rotates. When the height is sufficient, connect the wiring clamp 1 to the terminal of the equipment under test for testing. After the test is completed, first loosen the wiring pliers 1, retract the telescopic insulating rod 2 downwards, and turn the winding handle 5 at the same time to wind the test line 3 to complete the test work.
