Description

A special tool for secondary cable alignment

Technical field:

The utility model relates to electric power construction tools, in particular to a special tool for secondary cable alignment.

Background technique:

During the construction and transformation of the substation, the secondary cable alignment is an essential project. The length of the secondary cable is relatively long, and the number of internal cables is large. During the test, simple one-time tools are used for alignment. , generally use batteries, wires and light bulbs, and judge by whether the light bulbs emit light. When the cable distance is long, testers need to shout to each other, or be equipped with walkie-talkies. Poor, easy to make mistakes, not conducive to the construction of the secondary cable alignment, affecting the construction efficiency.

Invention content:

The purpose of the utility model is to design a special tool for secondary cable alignment with reasonable structure and convenient use.

The technical scheme of the utility model is a special tool for secondary cable alignment, which includes a wire clip and a box body. The parallel circuit composed of , indicator light and buzzer is connected in series, the positive pole of the battery is connected to the wire test terminal, the parallel circuit composed of a small vibrator, indicator light and buzzer is connected to the wire ground terminal, and the wire test terminal and the wire ground terminal are connected in parallel. There are wire clips respectively. the

The utility model has reasonable structure and is convenient to use, and can quickly complete the secondary cable alignment operation, thereby improving the construction efficiency. the

Description of drawings:

Fig. 1 is a schematic structural diagram of the utility model, and Fig. 2 is a schematic circuit diagram of the utility model.

Detailed ways:

The embodiment is described in detail in conjunction with the accompanying drawings, a special tool for secondary cable alignment, which includes wire clamps 3, 4, and a box body 2. A battery is arranged in the box body. The parallel circuit composed of , indicator light and buzzer is connected in series, the positive pole of the battery is connected to the wire test terminal 5, the parallel circuit composed of a small vibrator, indicator light and buzzer is connected to the wire ground terminal 6, and the wire test terminal and the wire are connected in parallel. The ground terminal is respectively provided with wire clamps 3, 4, and the utility model can also be provided with a hanging ring 1, which is convenient for the operator to carry. When the utility model is in use, it is necessary to use two special tools for secondary cable alignment at the same time to detect the secondary cable to be tested. Connect the grounding wire of the secondary cable alignment tool, and then connect any cable in the lead test end cable of one of the secondary cable alignment special tools, and connect the lead test end of the other secondary cable alignment special tool with each cable in the cable. Touch, when the special tool for secondary cable alignment flashes, sounds and vibrates, it means that the cable you are touching is the same cable as the cable being tested by another special tool for secondary cable alignment. Just mark it, and then continue to test other cables one by one. The utility model has reasonable structure and is convenient to use, and can quickly complete the secondary cable alignment operation, thereby improving the construction efficiency.
