Description
Technical field
The present invention relates to cable special equipment technical field, more particularly to a kind of high protective cable distribution box.
Background technique
With the increase of supply load, power cable is widely used.In long range laid processes, need more
Root cable connection can be only achieved using required length, and in practical laid processes, larger-diameter high-tension cable length is often
It is transported, the restriction of the factors such as mounting and installation difficulty, the size of cable reel, it is bigger to cause power cable line footpath, the company of use
The radical connect will be more.
At present multi-cable connection mode be generally directly connected to using middle connector, intermediate joint of electric cable because
The factors such as construction technology, construction personnel's quality, construction environment, influence construction quality, are easy to happen puncture short accident, cause fire
Calamity.Since cable laying space is smaller, cable separation distance is smaller, certain cable in cable shaft or tunnel punctures
Or when short circuit accident, often involve cable all in entire cable shaft or tunnel, serious influence electric system
Safe operation, also brings biggish economic loss for power consumer.
In face of the above problem, power supply unit or unit in charge of construction often use high-voltage cable middle joint box to cable intermediate joint into
High-tension cable intermediate connector is enclosed in inside armored cassette shell by row disposition, once cable intermediate joint is hit
Explosion accident is worn, periphery can be effectively protected other electric power facilities, be prevented secondary under the protection of cable explosion-proof box
The generation of injury.Cable intermediate joint after construction is protected, anti-explosion box for cable middle connector is generallyd use and carries out the later period
Protection, there are two types of currently used cable explosion-proof boxes, linear cable explosion-proof box and flexible cable armored cassette, be metal manufacture
Or glass steel making, product appearance is in strip column, without flexible dilatability.Due to cable be disk contracting or be laid in cable duct or
In cable shaft, general cable intermediate connector construction and laying can all lead to cable torsional deformation, exactly because cable distortion becomes
Irregular curved state is presented in shape, and after causing cable intermediate joint to construct, cable explosion-proof box is unable in appropriate cable indirectly
Cable intermediate joint, cannot effectively be fastened in shell, cause cable explosion-proof box that can not install or install by the torsional deformation of head
It is difficult.The connection type that cable flexible explosion-proof box is cooperated in structure using convex ribs and groove gap, preferably realizes explosion-proof
Box and the curved technical requirements of cable synchronizing, reduce difficulty of construction, facilitate site operation.Although flexible cable armored cassette can
Preferably cable intermediate joint is effectively protected, but if cannot be facilitated when encountering electric power transformation or increasing route
Slave cable connection punish out duplexure, be unfavorable for adding for the engineered and branched line in later period.
Therefore, it develops that a kind of sealing protection effect is good, the high protective cable distribution box that lines branch is added may be implemented
The problem of being those skilled in the art's urgent need to resolve.
Summary of the invention
The present invention is directed to solve one of above-mentioned technical problem in the prior art at least to a certain extent.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of high protective cable distribution box connects at least two sections of high-tension cables；Further include: cabinet, cover board, cable accessory,
For being connected to the bilateral casing seat of two sections of high-tension cables；
Side opening on the cabinet；
The cover board is interlocked with the box opening side；
One end of the cable accessory is connect with one end of the high-tension cable, and the other end is connected with the double end casing
It connects；
The both ends of the cabinet are equipped with the conducting wire connecting cylinder being pierced by for the high-tension cable other end；
The bilateral casing seat sets there are three and is placed side by side the box house；There are two being set on the bilateral casing seat
Interface connects one to three cable accessory on one interface of the bilateral casing seat.
Beneficial effect by adopting the above technical scheme is that medium and high voltage cable of the present invention is attached by two-tube block set, double
The interface of logical casing seat can connect 1-3 cable accessory simultaneously, can increase high-tension cable branch by bilateral casing seat, real
Now to the transformation of Voltage Cable Lines Construction.
Preferably, the bottom surface of the box house is equipped with mounting plate, and the bilateral casing seat is U-shaped, three bilaterals
Top in the middle part of casing seat is equipped with metal bead, and the metal bead connect with the mounting plate by fixing bolt and fixes institute
State bilateral casing seat.Bilateral casing seat is connect with mounting plate, can be by pair on mounting plate after mounting plate is taken out out of cabinet
Logical casing seat takes out together, convenient that bilateral casing seat and route are overhauled and safeguarded.
Preferably, it includes: preceding plug-in cable fittings and rear plug-in cable fittings that the cable is attached, and the preceding plug-in cable fittings are with after
Plug-in cable fittings respectively connect the high-tension cable, and the preceding plug-in cable fittings are connected with the interface of the bilateral casing seat
Logical, the rear plug-in cable fittings are connect with the preceding plug-in cable fittings.After being sequentially inserted into 1-2 on preceding plug-in cable fittings
Plug-in cable fittings realize adding for high-tension cable branch.
Preferably, three piece cable surfaces of the box inside at the conducting wire connecting cylinder are enclosed with high-tension cable three
Fingerstall plays a protective role to the high-tension cable bifurcation.
It preferably, further include rubber seal semi-ring for sealing the high-tension cable, two rubber seal semi-rings
It is interlocked and is placed in the conducting wire connecting cylinder, the two sides of the rubber seal semi-ring are provided with extruding metal item, and the rubber is close
The inside of envelope semi-ring is equipped with bolt, and the extruding metal item of the two sides of the rubber seal semi-ring is bolted.Pass through two
A extruding metal item squeezes rubber seal semi-ring, and rubber seal semi-ring can protrude after being squeezed to periphery, and then keep rubber close
Seal the more tight of the external sealing of semi-ring and high-tension cable.
Preferably, the cable for positioning to high-tension cable is equipped with close to the side of the conducting wire connecting cylinder in the cabinet
Fixing clamp, the fastening clip for cable of the positioning and the sidewall weld of the cabinet are fixed.After construction of high voltage cable, cable
