Embodiment 1）

[0040] See Figure 1 to Figure 4 , The quick-plug cable branch box of this embodiment is mainly composed of a box body 1, an insulator 2, a copper bar 3, a connecting wire 4, a T-shaped cable terminal 5, a straight line adapter 6 and an insulating partition 7.

[0041] The box body 1 is in the shape of a cuboid as a whole, and the interior of the box body 1 is hollow. In this embodiment, the external dimensions of the box body 1 are preferably 680mm×535mm×1150mm (length×width×height) according to the practical experience of the operation, so as to adapt to the maintenance of the ring network cabinet Sometimes the working site is narrow and irregular, and the reserved length of the original line and cable of the ring network cabinet is not enough. The front of the upper part of the box body 1 is provided with a box door 11 which can be opened and closed. An openable cable passage door 14 is provided; 4 rollers 15 with foot brakes are fixedly installed at the four corners of th...

Abstract

The invention provides a rapid plugging / pulling cable branching box. The branching box comprises a box body, three insulators, three copper bars, three connection wires, three T-shaped cable terminals, three straight line adapters and an insulation separation plate, wherein the insulators, the copper bars, the connection wires and the T-shaped cable terminals are arranged in the box body. Each of the straight line adapters comprises a conductive rod, an insulation layer, a rapid clamping head and a housing. One end of each of the straight line adapters is electricallyconnected with one T-shaped cable terminal in the box body correspondingly. The straight line adapters, the T-shaped cable terminals, the connection wires and the copper bars form a three-phase electric access. In use, the copper bars are correspondingly connected with three phase wires A, B and C of a ring main unit incoming cable. The straight line adapters are quickly clamped with rapid joints of three bypass cable joints via the rapid clamping heads. The branching box is simple in structure, low in cost and convenient to achieve. Laying distances of flexible bypass cables can be greatly reduced in use, so a difficulty in remote laying of power supply points and flexible bypass cables is solved and rush repair efficiency is increased.

Description

technical field [0001] The invention relates to the field of power supply line bypass operation equipment, in particular to a quick-plug cable branch box used for bypass operation and maintenance of a ring network cabinet. Background technique [0002] During the bypass operation of cable lines, the bypass cable and related equipment are generally used to quickly connect a bypass power supply line on site, across the cable line section or equipment for maintenance or emergency repair, and the bypass line replaces the original line by switching the gate Power is supplied to users, and at the same time, construction personnel maintain, repair and replace the original cable line to be repaired or equipment under power failure. When bypassing the ring network cabinet for maintenance, there are two main difficulties in the construction of the bypass cable system: one is to have a power point: generally connected to the spare interval of the nearby ring network cabinet; Frequent ...
