Referring to Fig. 2～Fig. 4, in the interior undermost lower compartment 33 of cabinet 1, be provided with damp-removing device 4, damp-removing device 4 comprises the Balance device 41 on base plate 40, base plate 40 is placed on the bottom in cabinet 1, on the two ends of the crossbeam 411 of Balance device 41, is supported with the first platform 421 and the second platform 422 respectively by the first roller 412.The bottom of the first track 431, the first tracks 431 that wherein the first platform 421 peripheries are provided with annular is supported on by leg 441 on the base plate 40 of cabinet 1 bottom, and the second platform 422 peripheries are provided with the second track 432 of annular.Each track limits respectively the platform of corresponding side can only do vertical moving up and down, and is provided with the second roller 433, the second rollers 433 and fits on four sides with corresponding track inwall on each platform and between corresponding track.
On the first platform 421, be provided with the first contact terminal 451 of the first contactor 45 of contact, on the second platform 422, be provided with silica gel box 46, the silica gel (not shown) of using for placing the moisture absorption in silica gel box 46, the bottom of silica gel box 46 is provided with electric-heating-wire-heating device 461.
On the dividing plate 2 of separation intermediate compartment 32 and lower compartment 33, the position relative with silica gel box 46 is provided with opening 21, dividing plate 2 belows are provided with seal cover 47, the size and shape of seal cover 47 and opening 21 adaptations, seal cover 47 can move along horizontal direction by drivings such as motors, open or seal opening 21, and certain transmission mechanism can be set, when transmitting motor actuating force, can support seal cover 47 again, make it remain on dividing plate 2 belows.Being provided with the first corresponding position of contact terminal 451 the first contact chip 452, the first contact terminals 451 that coordinate with it and contacting with the first contact chip 452 and can make the first contactor 45 conductings of dividing plate 2 bottoms and the first contactor 45.
The second position corresponding with the second contact terminal 481, contact terminal 481, the second platform 422 bottoms that is also provided with the second circuit switch 48 of contact on base plate 40 is provided with the second contact chip 482.The second platform 422 belows are also provided with solenoid 49, are fixed on base plate 40.The second contact terminal 481 contacts and can make 48 conductings of second circuit switch with the second contact chip 482.Usual the first contactor 45 with second circuit switch 48 all in not contacting the state of not conducting.
Lower compartment all offers respectively louvre 331 on 33 two sides, louvre 331 seals by sealing plate 332, sealing plate 332 can paste the inside sidewalls of compartment 33 to do moving horizontally of front and rear direction, thereby seals or open louvre 331, and sealing plate 332 can drive by motor.The interior both sides of lower compartment 33 are also respectively equipped with fan 333, same, and fan 333 can paste the madial wall of compartment 33 to do moving horizontally of front and rear direction, and this fan 333 also can drive by motor.
Above-mentioned motor, contactor and solenoid are all controlled by control module.
During use, the silica gel of the moisture absorption is imported in silica gel box 46, and the balance of accurate adjustment Balance device 41, make now two platforms keep balance.In power distribution cabinet, produce condensed water, and silica gel absorbs after steam for a long time, mass penalty, can cause thus Balance device 41 imbalances, the second platform 422 of now placing silica gel box 46 sinks slightly, and the first platform 421 quilt upwards arches upward, after this, the course of work of damp-removing device 4 is as follows:
1) the first contact terminal 451 contacts with the first contact chip 452, the first contactor 45 conductings, and control module is controlled the motor action that drives seal cover 47 thus, makes seal cover 47 move to opening 21 and by opening 21 sealings;
2) control module is controlled the motor action that drives sealing plate 332 again, and sealing plate 332 is removed from the position of sealing louvre 331, and controls the motor action of drive fan 333, dispels the heat in the position that fan 333 is pulled to louvre 331;
3) control module is controlled solenoid 49 energisings, solenoid 49 is inhaled the second platform 422 downwards, the second contact terminal 481 is contacted with the second contact chip 482,48 conductings of second circuit switch, control module is controlled thus electric-heating-wire-heating device 461 and is started, and under default time and temperature parameter to the silica gel heating in silica gel box 46 (silica gel activating), silica gel is evaporated completely the steam of absorption with suitable temperature and time, and this silica gel activating process will be assisted and accelerate to the fan 333 of both sides;
4) after the silica gel activating process set is complete, control module is controlled solenoid 49 power-off, therefore silica gel make Balance device 41 balance again because recovering to absorb steam quality before, the first platform 421 declines and makes the first contact terminal 451 and the first contact chip 452 separately, the first contactor 45 disconnects, after this, control module is controlled the motor action that drives seal cover 47, make seal cover 47 remove opening 21 is opened from opening 21, control the motor action that drives sealing plate 332 simultaneously, after being moved, sealing plate 332 again seals louvre 331, fan 333 is pushed back original position.So far, whole power distribution cabinet will recover whole sealing status again.
Under the outside of power distribution cabinet, can be provided with liquid level detection device, when power distribution cabinet during by water logging silica gel activating process will can not carry out, and only at water, step back just and can carry out silica gel activating process.
