Description
Technical field
The invention belongs to cable resist technology in power domain, be specifically related to a kind of buried cable line dehumidification system.
Background technology
Buried cable transmission and disttrbution accounts for the critical role of electric power transmission, the especially underground near substation control system
Cable is than comparatively dense, and in order to protect buried cable and affiliated facility, moisture-proof anticorrosive is one of important means.Currently for underground
Cable moisture-proof anticorrosive measure generally uses isolation method, but isolation can only stop cable not to be immersed in water, it is impossible to thoroughly avoid
Moist.
Summary of the invention
The present invention is directed to the problem that current buried cable line is easily corroded because of humidity, it is provided that a kind of buried cable line removes
Wet system.
Technical scheme: a kind of buried cable line dehumidification system, many spool docking form total spool, in bus
Cable being distributed in pipe, seals being connected to the adapter that dehumidifies between adjacent spool, described dehumidifying adapter includes can be with line
The joint of pipe ferrule docking and auxiliary tube, described auxiliary tube external diameter is more than spool external diameter so that auxiliary tube least significant end is less than
Spool least significant end；The upper end of auxiliary tube inner chamber connects has suction branch, auxiliary tube lower end to be provided with and the pipe of spool inner space
The mouth of a river under in；At least in an auxiliary tube connect have drying device, the suction branch of remaining auxiliary tube successively with the house steward that bleeds
Connection, the house steward that bleeds connects with negative pressure ventilation device.
The bottom discharge mouth of the extraneous connection in bottom.Bottom discharge mouth is provided with check valve.
Descend in described pipe at the mouth of a river or bottom discharge mouth or suction branch and be provided with drainage screen.
Between described spool and dehumidifying adapter, telescopic compensator is set.
Beneficial effects of the present invention: the present invention by means of dehumidifying adapter, it is possible to by be divided into inside spool spool intracavity space and
Multiple dehumidifying adapter interlayer cavity spaces, can not only uniformly bleed dehumidifying by multistage, and the adapter interlayer cavity that dehumidifies can be deposited
Storage excessive moisture, makes excessive moisture enter inside dehumidifying adapter interlayer cavity, prevents cable to be soaked in water and cause corrosion etc.
Problem.It is additionally provided with bottom discharge mouth, it is possible to outside making to ooze with spool under unnecessary hydrops bottom dehumidifying adapter interlayer cavity.
Accompanying drawing explanation
Fig. 1 is the attachment structure schematic diagram of the present invention；
Fig. 2 is B portion structure for amplifying schematic diagram in Fig. 1；

Detailed description of the invention
Buried cable line 2 dehumidification system as described in Figure 1, many spool 1 docking form total spool 1, divide in total spool 1
It is furnished with cable 2, seals between adjacent spool 1 being connected to the adapter 3 that dehumidifies.
Dehumidifying adapter 3 as shown in Figures 2 and 3, including the joint that can dock with spool 1 ferrule and auxiliary tube
31, described auxiliary tube 31 external diameter is more than spool 1 external diameter so that auxiliary tube 31 least significant end is less than spool 1 least significant end.Auxiliary tube 31
The upper end of inner chamber connects has suction branch 7, auxiliary tube 31 lower end to be provided with the lower mouth of a river 35 with in the pipe of spool 1 inner space.Make
In spool 1 in the unnecessary hydrops interlayer cavity 32 automatically into dehumidifying adapter 3.
At least connect in an auxiliary tube 31 and have drying device 4, preferably arrange dry in total spool 1 one end or middle part
Device 4.The suction branch 7 of remaining auxiliary tube 31 connects with the house steward 6 that bleeds successively, bleeds house steward 6 with negative pressure ventilation device 5 even
Logical.
Manage and be provided with drainage screen 33 at the interior lower mouth of a river 35 or bottom discharge mouth 34 or suction branch 7.Can also spool 1 with
Between dehumidifying adapter 3, telescopic compensator is set.Telescopic compensator can use existing compensator.
Embodiment 2: on the basis of embodiment 1, the bottom in dehumidifying adapter 3 interlayer cavity 32 has been in communication with the outside bottom again
Discharge outlet 34.See Fig. 2 and Fig. 3, bottom discharge mouth 34 is provided with check valve.
