Abstract
The utility model discloses a cable distribution box of a low-pressure cabinet, which comprises a row of low-pressure cabinets and distributing boxes containing cables; the top surfaces of the row of the low-pressure cabinets are contacted and connected with a row of distributing boxes; each distributing box is internally erected with at least two layers of horizontal cable brackets; the top surface of each low-pressure cabinet is provided with a threaded hole; one side surface of the distributing box is provided with a cable outlet hole; each strand of cables enters the distributing box from the threaded hole, is supported by the cable bracket and penetrates out from the cable outlet hole; and the distributing box is provided with a box door in which a longitudinal partition plate is not arranged. The arrangement of the design space is neater, can improve the percent of pass of the bending radius of cable laying, reduces the use of customized tee joints of a cable tray, shortens cable route, saves the using amount of cables, and can be widely applied in cable distribution of the low-pressure cabinets adopting the cable outgoing and distributing modes, and is especially suitable for complex low-pressure cable outgoing of large-scale industrial substations and civil construction substations.
Description
Technical field
The utility model relates to a kind of low-voltage cabinet and the casing that holds outgoing cable.
Background technology
In the prior art, the mode that the low-voltage cabinet outlet adopts cable testing bridge to join threeway is usually carried out distribution, for simple cable arrangements, generally adopts the single-layer cable crane span structure to be equipped with threeway and carries out distribution; Outlet situation for complexity: adopt double-deck crane span structure to be equipped with threeway and carry out distribution.Cable testing bridge is furnished with two kinds of form: A: " superimposed " arranges, promptly two-layer crane span structure projection overlaps; The shortcoming of wiring mode is that the threeway outlet of up/down perforation has taken the big quantity space of lower floor's crane span structure, causes the cable plot ratio to raise.The code requirement plot ratio is not more than 40%.B: " staggering " arranges that promptly two-layer crane span structure projection is parallel; The shortcoming of this wiring mode be crane span structure stagger install after, the number of times of quarter bend increases during cable laying, the Cable Bending Radius qualification rate is difficult to more guarantee that difficulty of construction strengthens.
Summary of the invention
The purpose of this utility model provides a kind of low-voltage cabinet cable distribution box, and the cable use amount is big in the time of solving conventional low cabinet cable outlet, and the bending number of times is more when laying, the technical problem that difficulty of construction is big.
For achieving the above object, the utility model adopts following technical scheme:
A kind of low-voltage cabinet cable distribution box, comprise row's low-voltage cabinet and the distributing cabinet that holds cable, it is characterized in that: the end face of described row's low-voltage cabinet is connected with row's distributing cabinet contact, the distributing cabinet internal frame be provided with two-layer at least level to cable tray, the end face of each low-voltage cabinet has through wires hole, there is wire hole a side of distributing cabinet, each strand cable enters distributing cabinet from each through wires hole, supported by cable tray and pass from wire hole, distributing cabinet is connected with chamber door, no longitudinal baffle in the case.
Described low-voltage cabinet and distributing cabinet are that inner frame adds the coaming plate structure, and cable tray is connected with the framework of distributing cabinet, and the upright of frame projection of distributing cabinet overlaps with the upright of frame of low-voltage cabinet.
Height≤the 800mm of described distributing cabinet, with the wide uniform thickness of low-voltage cabinet, and all there is chamber door front and back.
The chamber door of described distributing cabinet is double door or single open-door.
The interlamellar spacing of described cable tray can be 180～200mm.
Described cable tray can be angle steel or channel-section steel.
Compared with prior art the utlity model has following characteristics and beneficial effect:
(1) owing to can support be set according to cable specification and reasonable quantity in the distributing cabinet, cable arcing point range of choice in distributing cabinet increases, and has guaranteed the bending radius of cable, improves the bending radius qualification rate of cable laying.
(2) owing to cancelled cable testing bridge, reduce the use of customization threeway; Shorten the cable route, saved the cable consumption, accelerated the installation progress of low-voltage cabinet outlet cable.
(3) owing to adopt vertical skeleton of low-voltage cabinet and basic channel-section steel to carry out load-bearing, reduce suspension bracket and other annexes, reduce the steel use amount of erection bridge, make low-voltage cabinet cable installation cost reduced rate reach 50%;
(4) distributing cabinet by integral body has replaced stacked crane span structure, and spatial placement is more neat, has promoted the whole impression quality of switchgear house engineering.
The utility model has overcome that cable plot ratio in the conventional low cabinet outlet method is big, during cable laying quarter bend often, the Cable Bending Radius qualification rate is difficult to shortcomings such as assurance, difficulty of construction increasing.
The utility model can be widely used in adopting the low-voltage cabinet cable wiring of outlet wiring mode, is particularly suitable for the complicated low pressure outlet of large scale industry and Civil Building Transformer Station.
