Description
Technical field
The invention belongs to cable protection techniques in power domain, and in particular to a kind of buried cable line dehumidification system.
Background technology
Buried cable transmission and disttrbution accounts for the underground near the critical role of power transmission, especially 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 use isolation method, but isolation can only prevent cable from not being immersed in water, and can not thoroughly avoid
It is moist.
Invention content
The present invention for current buried cable line easily because humidity by corrosion the problem of, a kind of buried cable line is provided and is removed
Wet system.
Technical scheme of the present invention：A kind of buried cable line dehumidification system, more spool docking form total spool, in bus
Cable is distributed in pipe, to being connected to dehumidifying connector, the dehumidifying connector includes can be with line for sealing between adjacent spool
The connector and auxiliary tube of pipe ferrule docking, the auxiliary pipe outside diameter are more than spool outer diameter so as to be less than auxiliary tube least significant end
Spool least significant end；The upper end of auxiliary tube cavity is connected with suction branch, and auxiliary tube lower end is provided with the pipe connected with spool inner cavity
Interior collector nozzle；Drying device at least is connected in an auxiliary tube, the suction branch of remaining auxiliary tube is successively with being evacuated manifold
Connection, pumping manifold are connected with negative pressure ventilation device.
The bottom discharge mouth of bottom external world connection.Check valve is installed on bottom discharge mouth.
In the pipe filter screen is provided at collector nozzle or bottom discharge mouth or suction branch.
Telescopic compensator is set between the spool and dehumidifying connector.
Beneficial effects of the present invention：The present invention can will be divided into cavity space in spool by means of the connector that dehumidifies inside spool
Between and multiple dehumidifying connector interlayer cavity spaces, can not only multistage be uniformly evacuated dehumidifying, and dehumidifying connector interlayer cavity energy
Excessive moisture is enough stored, excessive moisture is made to enter inside dehumidifying connector interlayer cavity, cable is prevented to be soaked in water and causes corruption
The problems such as erosion.Dehumidifying connector interlayer cavity bottom is additionally provided with bottom discharge mouth, can make to ooze under extra ponding with outside spool.

Specific embodiment
2 dehumidification system of buried cable line as described in Figure 1, the more docking of spool 1 form total spool 1, divide in total spool 1
Cable 2 is furnished with, sealing is to being connected to dehumidifying connector 3 between adjacent spool 1.
Dehumidifying connector 3 as shown in Figures 2 and 3, including the connector and auxiliary tube that can be docked with 1 ferrule of spool
31,31 outer diameter of auxiliary tube is more than 1 outer diameter of spool so as to which 31 least significant end of auxiliary tube be made to be less than 1 least significant end of spool.Auxiliary tube 31
The upper end of inner cavity is connected with suction branch 7, and 31 lower end of auxiliary tube is provided with collector nozzle 35 in the pipe connected with 1 inner cavity of spool.Make
Extra ponding is automatically into the interlayer cavity 32 of dehumidifying connector 3 in spool 1.
Drying device 4 at least is connected in an auxiliary tube 31, preferably in total 1 one end of spool or middle part setting drying
Device 4.The suction branch 7 of remaining auxiliary tube 31 connects successively with pumping manifold 6, and pumping manifold 6 connects with negative pressure ventilation device 5
It is logical.
In pipe filter screen 33 is provided at collector nozzle 35 or bottom discharge mouth 34 or suction branch 7.Can also spool 1 with
Telescopic compensator is set between dehumidifying connector 3.Existing compensator can be used in telescopic compensator.
Embodiment 2：It is in communication with the outside on the basis of embodiment 1, and in the bottom of dehumidifying 3 interlayer cavity 32 of connector and has bottom
Discharge outlet 34.Referring to Fig. 2 and Fig. 3, check valve is installed on bottom discharge mouth 34.
