Provided with overflow valve 36 in 40, the hinged place of the switch cabinet body 1 and body door 33 is provided with torsion spring.
When the moisture that the humidity sensor 9 in switch cabinet body 1 is experienced in switch cabinet body 1 is too high, signal is transmitted
To centrifugal blower 8, centrifugal blower 8 receives signal and simultaneously started, after wind-force is dried by drier, by solenoid directional control valve 7, so
Afterwards again by the access switch cabinet body 1 of dehumidification pipe 13, by the moisture in switch cabinet body 1 by being discharged except wet hole, so that will
Moisture in switch cabinet body 1 is removed, and when the ammeter 15 in switch cabinet body 1, detects the electrical equipment member in switch cabinet body 1
Part causes its electric capacity to decline because temperature is too high, and when excessive by the electric current of electric elements, centrifugal blower 8 starts, and electromagnetism is changed
Commutate, the wind-force of centrifugal blower 8 is entered in switch cabinet body 1 by driving tube 6, and pass through three-way connection 5 to valve 7
Respectively enter in the fixed cover 4 at switchblade knife 2 and earthing switch blade 3, by the air admission hole on fixed cover 4, enter actuating sleeve
In 25, the air admission hole in the present embodiment is connected with the first arc air inlet duct 24 first, due to first baffle 22, second baffle
28 and third baffle 26 cavity volume of actuating sleeve 25 is divided into three cavitys, when air pressure is excessive in one of cavity, will push away
Dynamic third baffle 26 rotates, because the radian in the center of circle to the center of circle of second row stomata 27 of the air admission hole is more than 90 °, therefore at least
Need to be rotated by 90 °, when such air admission hole is turned in the first arc air inlet duct 24 more than 90 °, air admission hole and second row stomata 27
It just can turn on, therefore need to overcome magnet 32 to be rotated by 90 ° the attraction of switchblade knife 2, the air pressure in such driving chamber passes through
Through hole 31 on two steam vents 27 and cover plate 30 with the corresponding position of second row stomata 27 discharges, and air pressure is in gentle state, this
When positioned at the opposite side of switchblade knife 2 magnet 32 it is attractive to switchblade knife 2 because switchblade knife 2 rotation exceed
90 °, there is the face of interaction, the relative magnetic with original side with switchblade knife 2 positioned at the magnet 32 of the opposite side of switchblade knife 2
The suction of iron 32 is larger, therefore by switchblade knife 2 toward opposite side adhesive, switchblade knife 2 is closed, and similarly earthing switch blade 3 is also closed,
So as to which controlling switch cabinet automatically powers off protection, without using fuse, now centrifugal blower 8 is closed, and the now quilt of actuating sleeve 25
90 ° are have rotated, because first row stomata 23 and second row stomata 27 are opened up along the axisymmetrical of actuating sleeve 25, works as actuating sleeve
When 25 180 ° of rotation, the position of second row stomata 27 is replaced by first row stomata 23, the second arc air inlet duct 29 and air inlet
Hole is connected, and when closure switch plug-in strip 2 and earthing switch blade 3 is needed, as long as restarting centrifugal blower 8, wind-force is to second gear
The active force of plate 28, because the power acted on first baffle 22 can not rotate switchblade knife 2 and earthing switch blade 3, therefore can only be right
The actuating pressure of second baffle 28, so that actuating sleeve 25 is reversely rotated, because first row stomata 23 instead of second row stomata 27
Position, and the position of the air admission hole on fixed cover 4 is constant, therefore air admission hole and second row stomata 27 are still radian is more than 90 °
Thus need to reversely rotate more than 90 ° of angle, such switchblade knife 2 and earthing switch blade 3 are flipped up more than 90 °, similarly
Attracted by the magnet 32 of top, to drive shaft in air pressure when being drained, the suction shaft plug-in strip 2 of magnet 32 and earthing switch blade 3 are inhaled
Splice grafting leads to, while drive shaft have rotated 180 ° of resets again, so only needs to control the startup and closing of centrifugal blower 8, can just control
Closure and the unlatching of switchblade knife 2 and earthing switch blade 3 processed, its is simple in construction, without unnecessary equipment, makes also simple, without
Electric elements in switch cubicle just can be effectively protected by fuse, with dehumidifying and automatic opening closure switch plug-in strip 2
With the function of earthing switch blade 3, and when the air pressure in switch cabinet body 1 is excessive, opened in the overflow valve 36 in second channel 40,
Air pressure is by second channel 40, into the second locking slot 39, to the active force of push pedal 37 in the second locking slot 39, promotes push pedal
Latch segment 42 is ejected the second locking slot 39 by 37, and switch cabinet body 1 and body door 33 block 42 that is no longer locked are stuck, switch cubicle sheet
Air pressure in body 1 pushes body door 33 open a gap and carries out pressure release, after pressure release is finished, torsion spring release reseting elasticity, by body
Door 33 resets, and one end that the latch segment 42 in the present embodiment stretches into the second locking slot 39 is hemispherical, the one of such latch segment 42
End stretch into again in the second locking slot 39, switch cabinet body 1 is closed, play pressure release effect and automatically reset effect, when want
When artificial unlatching switch cabinet body 1, start blower fan and simultaneously open the first stop valve 41, wind power direct was connected first passage 35 and entered
Enter the second locking slot 39 to push latch segment 42 open, body originally can be opened, body door 33 is opened and closed by wind-force, also prevented
Stopped switch cubicle by malicious sabotage, controller can also be set in the present embodiment in switch cabinet body 1, for it is overall control it is whole
Individual dehydrating unit.
Preferred described remove in wet hole of the present embodiment is provided with the first check valve 20, by above-mentioned technical proposal, can keep away
Exempt from the extraneous moist air of tool when usually dehydrating unit is not actuated, pour in down a chimney in switch cabinet body 1, so as to when switch
Moisture is difficult accumulation in cabinet body 1.
Preferred first check valve 20 of the present embodiment is connected with inclined mozzle 19, one end of the mozzle 19
Vertical header is connected with, the bottom of the header is connected with water storage box 16, and the water storage box 16 is connected with cooler pan
Outer wall laminating at pipe 18, the cooling coil 18 some electric elements corresponding with switch cabinet body 1, when moisture is single from first
When discharge into valve 20, blown to by drainage tube on vertical header, vapor adhesion is formed on the inwall of header
Droplet, is collected, it is to avoid the moisture containing steam reenters centrifugal blower 8 so that the bottom of header is flowed into water storage box 16
It is interior, repeat to dehumidify, improve the efficiency of dehumidifying, and the condensed water of collection is cooled down in switch cabinet body 1 by cooling coil 18
Electric elements, effectively make use of resource, energy-conserving and environment-protective.
The preferred dehumidification pipe 13 of the present embodiment, which is provided with heater box 11, the heater box 11, is provided with copper mesh 12, by
Generation cupric oxide can be reacted in copper and oxygen, therefore again after air water removal, can be by oxygen by copper mesh 12 hot in heater box 11
