Uninterrupted operation system of low-voltage distribution box

Abstract

The invention provides an uninterrupted operation system of a low-voltage distribution box. The system comprises a bypass distribution box, a low-voltage distribution box and an insulation tool. The system is characterized in that the system comprises a circuit breaker, an incoming connection cable and an outgoing connection cable; the incoming busbar of the low-voltage distribution box is a segmented busbar combination structure; a first busbar is connected with an incoming circuit breaker; a second busbar is connected with an incoming cable, and a connection hole is reserved in the busbar; the outgoing busbar of the low-voltage distribution box is in a segmented busbar combination structure; the first busbar is connected with an outgoing circuit breaker; the second busbar is connected with an outgoing cable, and a connection hole is reserved in the busbar; when the low-voltage distribution box needs maintenance, an insulation tool is used to connect the incoming connection cable andthe outgoing connection cable of the bypass distribution box and the reserved connection holes of the incoming busbar and the outgoing busbar of the low-voltage distribution box to provide power for the load of the low-voltage distribution box; and uninterrupted operation during the maintenance of the low-voltage distribution box is truly realized.

Description

technical field [0001] The invention relates to the field of electric power maintenance live work, in particular to a low-voltage power distribution box non-stop operation system. Background technique [0002] With the development of our country's economy and the improvement of people's living standards, the importance of electricity is getting higher and higher, and there are higher requirements for the continuity of power supply. As an important part of the power supply system, the low-voltage distribution box is actively and regularly maintained. It is a very important task, especially the circuit breaker in the low-voltage distribution box, to ensure the normal power supply of the low-voltage distribution box, overload, short circuit, etc. Disconnecting the line under certain circumstances plays a decisive role, precisely because it has such a protective function, disconnecting the line under the condition of short circuit and high current, it is easy to generate an arc ...

Problems solved by technology

Although the power outage is planned and users are prepared to deal with it in advance, even so, it will still cause losses to many users, and even when the power supply is restored, electric shock accidents may occur to lower-level users
