The wall bushing 2 of the present embodiment is the column structure of an entity, and the junction of the wall bushing and tank body 1 uses close
Flange connection is sealed, wall bushing is full skirt at remaining.The overall length of wall bushing 2 of the present embodiment is 2.64 meters, stretches into the inner side of tank body 1
It is long 1.28 meters, the part long 0.4m of junction long 1.36 meters positioned at the outside of tank body 1；The maximum of this wall bushing 2 can be resistant to
550kV lightning impulse voltage, 500kV or so operating impulse voltage.During experiment, because the both ends of wall bushing 2 are installed respectively
On high-tension side sparking electrode and high-voltage connection, therefore the both ends of wall bushing are high-pressure side；And the plate electrode 11 inside tank body 1
For low-pressure side, to ensure tank body 1 and low-pressure side, connected between tank body 1 and plate electrode 11 using metal.
The air dry-set of the present invention is connected by two-stage filter with normal air compressor to be formed, two-stage filter
Export and be connected as the outlet of air dryer with vapor into valve.The two-stage filter of the present embodiment uses the U.S.
Xinteks companies, model XT-107F high-precision two-stage filter, the two-stage filter are included mainly by slightly imitating filter screen, honeybee
The first order of nest shape water trap, the water trap being connected with the water trap bottom and the automatic drain valve composition being connected with the water trap
Filter element, and using stainless steel wire and second level fibrous filter net made of special cotton；Second level fibrous filter net passes through
Pipeline is connected with the vapor intake valve 15 in the side wall of tank body 1.
The specific workflow of the present embodiment air dry-set is：In the starting stage of the regulation air pressure inside of tank body 1, contain
Having the Ordinary Compression air of water or various impurity, (high voltage has suction-operated to some impurity in air, so High-Voltage Experimentation
The air quality of room is all relatively poor) enter first order filter element and produce coalescence effect, more than 95% in compressed air
Water droplet, oil droplet and bulky grain will be attracted on thick effect filter screen, and moisture can condense into larger water droplet；Subsequently into sky
Gas and moisture separation phase, compressed air speed slow down so that impurity particle is assembled with water droplet on cellular water trap, carries
The water droplet of impurity particle flows to the device of draining along water trap bottom, and is discharged it by automatic drain valve, and now, compression is empty
More than 95% water droplet and large granular impurity are filtered out by first order filter element in gas, subsequently into second level fiber filter
Net.After air enters second level fibrous filter net, produced by the fibre structure air of the screen pack thousands of small
Whirlpool, while air is accelerated decades of times, and no-man's-land is centrally formed in whirlpool, and be not filtered out through first order filter element
Water droplet is vaporized, changes, filtered out again, and small to 5 μm of impurity particle is also filtered out completely by second level screen pack.Program institute
The source of the gas used can gather materials on the spot for compressed air.
In addition, in the case of air pressure needed for tank in vivo studies is less than 3 atmospheric pressure, air dry-set of the invention is also
Can use can provide hydrone concentration less than 3ppm, oxygen content 21% (volume), the high-purity of nitrogen content 79% (volume)
Synthesis of air compressor realize.The program decouples the effect of regulation compared with such scheme more preferably to humidity, air pressure, it is contemplated that is adopted
The volume and quantity factor of high-purity gas mixing gas cylinder, it can be adopted when air pressure needed for tank in vivo studies is less than 3 atmospheric pressure
Use this programme.
Fig. 5 is that two-stage filter+normal air source, high-purity synthesis of air source and untreated tank is respectively adopted
Between interior air pressure and relative humidity relation comparison diagram (respectively as figure orbicular spot, triangle and it is square shown in), as shown in figure 5,
It is obvious between the air pressure and humidity in tank body 1 to decouple substantially after two solutions are increased.Due to being used at source of the gas
Synthesis dry air, the content of this synthesis of air reclaimed water is considerably less, in 1m3Synthesis of air in only no more than 5mL
Water, therefore decoupling effect is optimal.
The atomizer of the present embodiment uses the tantalum metal atomization device of Beijing Puxi General Instrument Co., Ltd, model
B305002-01-01-00.Liquid water tank, rubber dropper, atomizer, the thin mouth that the atomizer mainly includes being sequentially connected are defeated
Switch valve is respectively equipped with tracheae, thick mouth appendix and compressed air gas cylinder, atomizer and thin mouth appendix, and is atomized
Nozzle is prepared by metal tantalum using common process, and thick mouth appendix is provided with switching valve；The atomizer is located at outside main tank body 1,
The atomizer of the atomizer is connected with the vapor of tank body 1 into valve 15.Atomizer is to be based on Venturi ejector principles, profit
High velocity air is formed by thin mouth appendix with compressed air, caused negative pressure drives aqueous water to spray together, and in atomizer
It is internal to be sprayed through making liquid water droplets become the particulate that nebulizes to surrounding splashing under high-speed impact from atomizer.
The temp.-humidity measuring apparatus of the present embodiment connects by the display main frame outside tank body 1 and installed in tank wall is reserved
Temperature Humidity Sensor at mouthful, which is connected, to be formed, and the probe of sensor is located inside tank body 1；Wherein, by showing the screen of main frame
The temperature and relative humidity at sensor are shown respectively；The measurement accuracy of temperature sensor is ± 0.5 DEG C, the survey of humidity sensor
Accuracy of measurement is ± 3%RH；The sealing shell maximum of sensor probe can bear 0.8MPa gas pressure intensity.
When reducing humidity in tank body 1 at ambient pressure, because tank body volume itself is larger, and gas pressure test is being changed
When, the absolute humidity in tank body is dropped into 3g/m as much as possible3Or it is following, present invention employs the method for a variety of wet downs mutually to tie
Close.It is logical into valve 15 in vapor by the way of continuously ventilation is filled when the humidity of tank body is much larger than extraneous ambient humidity
Enter the compressed air after double-filtration, (gas passes in and out valve when opening, if in tank for the gas outlet 14 of opening gas disengaging valve 13
Gas atmosphere superatmospheric and not toward ventilating in tank body, then the gas outlet outlet), so can be by the sky of high humility in tank body
Gas is gradually discharged, and will soon drop to the humidity in tank body near ambient humidity, and the speed that humidity declines afterwards starts to slow down,
At this moment drier can be put on the plate electrode in tank body by opening observation window, be further continued for filling ventilation, after a while,
Humidity will drop to a minimum, and this minimum is usually 3g/m3Left and right；Another way is first to take out to fill again, pumping
When at most allow to take out an atmospheric pressure, so the used time being pumped to using negative pressure pump near vacuum is very short, substantially on 10 minutes left sides
The right side, dry compressed air or synthesis of air are then filled with into main tank body again, are inflated on high pressure air gauge and show 1.2 greatly
Air pressure, gas outlet is then opened again, stand main tank body and discharge internal excessive gas, return to normal pressure.Due to main tank body volume
It is larger, when judging whether air pressure is normal pressure in main tank body, it is impossible to only merely also carefully to be listened to by the registration on air gauge
