Problems solved by technology

[0011]However, a large number of distribution boxes currently in use are directly connected to copper bars without protection, which will lead to:
[0012]① If someone touches the exposed copper wire, it will directly lead to the danger of electric shock;
[0013]② If any branch circuit breaks down, the whole branch box is in crisis;
[0015]④ If a fault occurs, it is very troublesome to find it, and it must be searched one by one
However, this patent still adopts ordinary copper bars for incoming and outgoing lines, which does not solve the problem of exposed copper bars, and is prone to the risk of electric shock when outgoing lines

Embodiment 1

[0089] A low-voltage cable branch box inlet and outlet connection method, adopting a modular structure, divides the low-voltage cable branch box inlet and outlet connections into three parts: busbar system 1, inlet module 2 and outlet module 3. The low-voltage cable branch box enters and exits The line connection is three busbars (three-phase); including one set of inlet module 2 (three-phase) and multiple sets of outlet module 3 (each set of three-phase), which can be divided into one input and three output, one input and four output, one Five in, one in and six out, etc., adopt modular combination; for example, a branch box of a real estate, one corridor is equipped with one outgoing line, and there are several outgoing lines in several corridors. Users can choose one in and out according to the number of corridors, and Choose the length of the bus according to the number of times. The incoming line is connected to the busbar system 1 through the incoming line module 2, and t...

Abstract

The invention discloses a method and a device for connecting an inlet wire and an outlet wire of a low-voltage cable branch box. A modular structure is adopted; the connection of the inlet wire and the outlet wire of the low-voltage cable branch box is divided into three parts, i.e. a bus system, an inlet wire module and an outlet wire module; the inlet wire is connected to the bus system through the inlet wire module; and the outlet wire is also connected to the bus system through the outlet wire module. The connection way of the inlet wire and the outlet wire comprises the steps that an inlet wire cable is connected to the inlet wire module, the module is connected to the bus system, meanwhile the outlet wire is connected to the outlet wire module, the outlet wire module is connected to the bus system, and the whole connection of the inlet wire and the outlet wire is finished. The method and the device have a high protection level, a load switch can switch total load current and certain short-circuit current; an obvious off point is provided to reducing the probability of shock accidents; due to a plugging way, the device is simply and conveniently mounted; due to high reliability, the power-off area is reduced during a failure; due to moveable parts, the device is free of maintenance and can be applied in a severe environment; and due to modularization, the device is easy to expand.

Description

technical field [0001] The invention relates to an electrical connection method and device, in particular to a connection method and device for incoming and outgoing lines in a low-voltage cable branch box, mainly used for cable connection of incoming and outgoing lines outdoors, in cable wells and in corridors. Background technique [0002] Cable branch box With the development of distribution network cabling process, when the distribution of independent loads with small capacity is relatively concentrated, cable branch boxes have been widely used to connect multiple branches of cables, because the branch box cannot directly operate each channel. It is only used as a cable branch, and the main function of the cable branch box is to branch or transfer cables. The so-called cable branching refers to: there are many small-area cables on a relatively long-distance line, which often leads to waste of cable use. Therefore, when going out to the power load, the main large cable is...
