Description
Technical field
The present invention relates to one kind to utilize six-component force balance, ensures the method and dress of direct charging type electric sprayed insulation
Put.Belong to the protection field of electron spray mechanical device.
Background technology
The factor of droplet carrying capacity is influenceed in electrospray techniques the structure type of electrode, charging modes, charging liquid
Physical property and surrounding environment.Wherein charging modes mainly have direct charging, induction charging, corona charging.It is directly rechargeable
Mechanism be point effect, metal electrode directly contacts with liquid medium, and in the presence of external electrical field, dielectric shows electricity
The effect of dipole, that is, polarize.Polar molecule turns over an angle, arrangement is tended to be neat, obtains the polarity of macroscopic view, shape
Into orientation polarization;The positive and negative charge of non-polar molecule is opened distance by the effect of opposite direction electric field force, also obtains macroscopic view
Polarization, formed displacement polarization.
When directly charging and corona charging produce arc discharge, droplet positively charged.Directly charging makes the charged effect of droplet
Preferably, next to that corona charging, the charging effect of induction charging are minimum.But in actual applications for security consideration, typically
Corona charging or induction charging can be selected.Safety problem is mainly reflected in:
First, the insulated lengths that ensure in inlet channel can ensure or entirely supply water that spraying system is isolated with ground;
2nd, directly charging high-field electrode and the direct touch-safe hidden danger of container are big, dangerous high.
Therefore electron spray feedwater insulation water valve is exactly to ensure the whole spraying system that supplies water using the insulating properties of sulfur hexafluoride
The key component of the isolation of system.Sulfur hexafluoride separated and identified what is come by Moissan and Lebeau first in 1900.It is
Burnt by sulphur in gas fluorine, followed by with aqueous slkali washing reaction product, prepared by removing less fluorinated compound.Until 70 years
In generation, it is best insulant that sulfur hexafluoride, which has been recognized,.Its dielectric strength is big, and safety, equipment volume is small, moderate cost etc.
Deng.Therefore, it is external to have increased since the sixties quickly using the number of devices of six-component force balance.
The content of the invention
The present invention is divided into machinery and controls two parts with single-chip microcomputer.Function primarily as direct charging type electric sprayed insulation
Water valve in water work.The key technology of invention is exactly to solve the difficulty that common water valve can not insulate under high voltages when closed
Topic.
The technical solution adopted in the present invention is:First magnetic valve (1), second solenoid valve (2), the 3rd magnetic valve (3),
Four magnetic valves (4) are attached using threaded connection with pipeline.Air gauge (5), water pressure gauge (6) top are connected through a screw thread and managed
Road connects.Correlation photoelectric sensor (7) is connected using threaded connection with water valve ectosome, fixes rear correlation photoelectric sensor
(7) with the horizontal 30 ° of angles.Transparent resin water pipe (8) is connected by being glued connection with pipeline.Water valve ectosome (9) uses glue
Connect and be connected with pipeline in succession.
Singlechip control part includes:Valve switch, correlation photoelectric sensor and 89C51 single-chip microcomputer I/0 mouth inputs
Connection.First magnetic valve (1), second solenoid valve (2), the 3rd magnetic valve (3), the 4th magnetic valve (4) and 89C51 single-chip microcomputers I/0
Mouth output end connection.
Electron spray feedwater insulation water valve of the present invention is realized in insulation.In the design of mechanical part as shown in figure 1,
In order to ensure having enough gas length in whole switch pipeline to ensure insulating properties, the air pressure of system is just greater than hydraulic pressure.Institute
Determine that air pressure is more than hydraulic pressure with the numerical value for needing to check air gauge 3 and water pressure gauge 4 before whole switch is started.
When switching unlatching, the 3rd magnetic valve 3, the 4th magnetic valve 4 are closed, and the first magnetic valve 1, second solenoid valve 2, which are opened, protects
Demonstrate,prove the proper flow of water;The first magnetic valve 1, second solenoid valve 2 are first shut off the flowing of exclusion of water, the 3rd magnetic valve when closed
3rd, the 4th magnetic valve 4 is opened.3rd magnetic valve 3, which is opened, to form sulfur hexafluoride gas-insulating in sulfur hexafluoride gas filling line
Post, while the water in pipeline is discharged.Waste water is discharged via the 4th magnetic valve 4.Now in order to ensure the sulfur hexafluoride in pipeline
The length of gas-insulated post can completely cut off high-tension electricity, need to measure the length of sulfur hexafluoride gas-insulating post.Existing measurement liquid level
Sensor be divided into direct contact-type and non-contact type.Direct contact type sensor need to be arranged in pipeline, come for the present invention
Say and do not apply to.And non-contact type price too expensive, considerably increase cost of the invention.So the design is used to penetrating
Formula photoelectric sensor, light is passed through using transparent material in the pipeline portions for setting up correlation photoelectric sensor, and inclined
Correlation photoelectric sensor is tiltedly set so that has the water time to reflect in the duct, sensor no signal.As shown in Figure 1 this
Partial pipeline be U-tube road such as the principle of linker, if ensure to have in pipeline water can be gathered in bottom ensure it is lithium
The length of sulphur gas-insulated post.Therefore correlation photoelectric sensor is arranged on the length of the sulfur hexafluoride gas-insulating post in U-tube
Spend the opening position of enough insulation.The principle of correlation photoelectric sensor detection liquid level is as follows, when being the air time in pipeline herein
Curb straightline propagation sensor does not react, and illustrates that the length of sulfur hexafluoride gas-insulating post is inadequate when in pipeline being herein water
There is no guarantee that insulation.Now because the refraction action light path of water changes, sensor, which is not received by light, will send signal.
Increase the length of sulfur hexafluoride gas-insulating post by adjusting air pressure again.
Technique effect:Sulfur hexafluoride gas has an excellent insulating properties, and dielectric strength is 3 times of air, arc extinction performance
It is 100 times of air, for uniform gap, the breakdown electric field of sulfur hexafluoride is about 89kV/cm when in 0.1MPa pressure.Water valve
The middle sulfur hexafluoride gas-insulating post that 10cm length be present, the dielectric strength of water valve are at least 10KV.
