Description

High voltage cable distribution box

technical field

The utility model belongs to the technical field of cable branching devices, in particular to a high-voltage cable branching box.

Background technique

High-voltage cable distribution box is a kind of electrical equipment used for outdoor cable distribution in power systems, improving power supply reliability and saving investment. It is widely used in urban streets, residential quarters, high-rise buildings, parks, schools and other places.

The box body of the high-voltage cable distribution box is provided with a box cover, and cables are arranged in the box body. During normal operation, the cable connection has high voltage when it is working. If the box cover is opened at this time, an electric shock accident may occur. And sometimes for maintenance, the box cover must be opened. If it is not possible to determine whether the cables in the box are live before opening, it is very dangerous.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a high-voltage cable distribution box, which can display whether the cables inside the box are electrified.

In order to solve the above technical problems, the utility model is solved by the following technical solutions: a high-voltage cable distribution box, including a box body, a cable is arranged in the box body, a live display device is arranged on the box body, the One end of the charged display device is connected to the detection device, and the other end is grounded. When the cable in the box is electrified, the detection device detects the voltage, and then the charging display device makes a corresponding display according to the detection result of the detection device.

In the above technical solution, preferably, the charged display device includes a dial and an indicator light, the dial is fixed on the upper part of the box, and the indicator light is fixed inside the dial. When the detection device detects that the cable is live, the indicator light will be bright.

In the previous technical solution, preferably, the detection device includes a metal sheet, and the metal sheet is close to the cable. Generally, alternating current is passed into the cable. After the metal sheet approaches the cable, a capacitance is formed between the cable and the capacitor, and the capacitor passes through alternating current. Therefore, as long as there is current in the cable, the metal sheet can transfer the current to the indicator light, making the indicator light The lights glow.

The beneficial effects of the utility model are: when the cable in the box is energized, the detection device detects the potential, and then the charging display device makes a corresponding display according to the detection result of the detection device, and warns personnel to avoid danger.
