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 linear adapter 6 and an insulating partition 7.

[0041] The box body 1 is in the shape of a cuboid as a whole, and the inside of the box body 1 is hollow. In this embodiment, the external dimension of the box body 1 is preferably 680mm×535mm×1150mm (length×width×height) according to the practical experience of operation, so as to adapt to the maintenance of the ring network cabinet. When the working site is small and non-standard, the reserved length of the original line cable of the ring network cabinet is not enough, etc. The upper front of the box body 1 is provided with a box door 11 that can be opened and closed, and the box door 11 can be locked by the box cover lock 12; the lower side surfaces of the box body 1 are provided with heat dissipation windows 13; There is...

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 bypass operation equipment for power supply lines, in particular to a quick-plug cable branch box used for bypass operation and maintenance of a ring main unit. Background technique [0002] In the process of cable line bypass operation, bypass cables and related equipment are generally used to quickly connect a bypass power supply line on site, and cross the cable line section or equipment to be repaired or repaired, and the bypass line is replaced by the original line through the switch. Supply power to users, and at the same time, construction personnel maintain, overhaul and replace the original cable line to be repaired or equipment under power outage. When overhauling the ring main unit during bypass operation, there are two main difficulties in the construction of the bypass cable system: First, there must be a power point: generally connected to the nearby ring network cabinet as a spare interval; Cross th...
