A low-voltage cable branch box inlet and outlet busbar system and its installation method

Abstract

The invention discloses a low-voltage cable branch box inlet wire and outlet wire bus system and a mounting way thereof. The system is characterized by being a modular structure which is formed by arranging a plurality of bus box modules in parallel in a low-voltage cable branch box, wherein each bus box module is a power supply item, the bus box modules form a plurality of power supplies; a plurality of bus mounting boxes 1 are arranged in each bus box module in parallel, and the bus system into which a plurality of inlet wire modules or outlet wire modules can be inserted in parallel is formed; buses are arranged in the bus mounting boxes, the bus mounting boxes are of enveloped structures of which the front surfaces are grids, and the buses are enveloped in the bus mounting boxes; and a plurality of parallel plugging sockets are arranged on the front surfaces of the bus mounting boxes, and a fixed screw hole is formed in the bus mounting box between every two plugging sockets. The system has high protection level, so that the probability of shock accidents is reduced; due to a plugging way, the system is simply and conveniently mounted; due to high reliability, the power-off area is reduced during a failure; due to moveable parts, the system 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...

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] ①In case 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] ④If 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
