Technical field
This practical information is related to transformer station's technical field, and in particular to a kind of dual-open type cable trench box.
Background technology
During current Substation Design, to reduce transformer station's floor space, reducing investment outlay, capacitor becomes with ground connection
High-tension cable and low-voltage cable one cable duct is often only set, under the limitation of this condition, height is laid if thinking to separate completely
Voltage cable and low-voltage cable, it is common practice to which the high-tension cable that capacitor becomes with ground connection is laid along cable duct, and low-voltage cable is adopted
Laid with pipe laying mode to neighbouring secondary cable ditch.Separate system of laying, the cable fire-proof generally used according to incomplete
Groove lays secondary cable.Both approaches have some following drawback：Need the steel pipe distance laid longer, by multiple bending,
Plumb joint is excessive, and seal is poor；And it is difficult that, in land marking, during reorganization and expansion may dig disconnected early stage has laid
Low-voltage cable；Secondary cable pipe laying needs guiding through cable duct when laying, and is made troubles to construction and O＆M；It is difficult to reduce enlarging
Degree, need to shift to an earlier date the reserved place embedded steel tube in enlarging equipment；During reorganization and expansion, lay new after need to groove box be opened
Low-voltage cable, this equally causes greatly difficult and security threat to construction.So under limited condition limitation, reasonable Arrangement
Cable duct structure, carries out a secondary cable subregion, it is to avoid high-low pressure cross-operation is particularly important.
Cable layment common method lays method including groove box, and groove box is put into a ditch as linear quadratic control cable
Groove box is laid altogether with power cable with laying for power cable, i.e. low voltage control cable.Due to the limitation of groove box space, it is difficult to meet
Fire protection requirement.
Utility model content
The purpose of this utility model is to be directed to above-mentioned deficiency, it is proposed that one kind solves the problems, such as height voltage cable ditch, O＆M altogether
Overhaul convenient dual-open type cable trench box.
The utility model is specifically adopted the following technical scheme that：
A kind of dual-open type cable trench box, including cable area and trench area, the wherein top in cable area are provided with the first lid
Plate, the top of trench area is provided with the second cover plate, the first cover plate with the second cover plate in same level and the second cover plate length
Degree is more than the length of the first cover plate, the low-voltage cable area in cable area including top and the high-tension cable area of bottom, the first cover plate with
Low-voltage cable area surrounds the cable chamber of closing, and the second cover plate surrounds the trench cavities of closing, high-tension cable area and groove with trench area
Area is interconnected.
Preferably, the top in the cable area and trench area is provided with cover plate framework, and the first cover plate is arranged at the second cover plate
On cover plate framework.
Preferably, the side in the low-voltage cable area is provided with the strut angle for stretching to the first cover plate and the second cover plate junction
Steel.
Preferably, the low-voltage cable area is provided with low-voltage cable area drainpipe, and the bottom of trench area is provided with main sewer, low
Voltage cable area drainpipe is connected with main sewer.
Preferably, the middle of the low-voltage cable area sets fire barrier.
Preferably, it is equipped with handle on first cover plate and the second cover plate.
The utility model has the advantages that：
After dual-open type cable trench box, when operating personnel carries out operation, if to high-tension cable operation, opening the
Two cover plates enter trench area, and low-voltage cable will not be touched by mistake；When carrying out operation to low-voltage cable, it is only necessary to open the first cover plate, nothing
It need to enter in trench area, secondary cable detours to secondary cable ditch without a cable duct is needed guiding through, and fundamentally solves engineering
The complexity that pipe laying is laid in work progress；In work progress, high-low pressure cross-operation is reduced, operation people is greatly protected
The safety of member.
Brief description of the drawings
Fig. 1 is the dual-open type cable trench box structural representation under the first cover plate and the second cover plate closing state；
Fig. 2 is the dual-open type cable trench box structural representation under the first cover plate and the second cover plate opening.
Wherein, 1 is cable area, and 11 be low-voltage cable area, and 12 be high-tension cable area, and 2 be trench area, and 3 be the first cover plate, 4
It is low-voltage cable area drainpipe for the second cover plate, 5,6 be main sewer, and 7 be support angle steel, and 8 be cover plate framework.
Embodiment
Embodiment of the present utility model is described further with specific embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of dual-open type cable trench box, includes the top of cable area 1 and trench area 2, wherein cable area
