Abstract
The utility model discloses a humidity generator which comprises an air inlet and outlet pipe; the air inlet and the air outlet of the air inlet and outlet pipe are respectively provided with a diverter three-way pipe and a confluence three-way pipe; one air outlet pipeline of the diverter three-way pipe is provided with a plurality of air flow regulators, and another air outlet pipeline is subsequently provided with a water glass tube which is filled with water and a moisture flow regulator; and the air outlets of a dry air flow regulator and the moisture flow regulator are respectively connected with the confluence three-way pipe. The humidity generator obtains appropriate humid air which meets requirements by adjusting the flow of the dry air and the moisture, so as to check if the change tendency of a humidity sensor is correct or not; because the accessories adopted are simple and convenient to be installed, the humidity generator has higher price than the prior humidity generators and is convenient to be carried.
Description
Technical field
The utility model relates to a kind of humidity generator that produces the moisture that requires when being used for that humidity sensor carried out verification.
Background technology
SF6 gas has stronger insulating properties, be widely used in the high voltage electric equipment, along with rapid development of national economy, SF6 gas high-voltage electrical apparatus is very universal in application on power system, but, use equipment for many years, be subjected to site environment, the influence of aspects such as weather conditions, the content of the minor amount of water in the SF6 gas often exceeds standard, and the content of the minor amount of water in the SF6 gas is unusual important index, and it not only influences the insulating properties of equipment, and moisture is under arcing, in gas, can decomposite poisonous or harmful suboxides material, equipment and materials is played corrosiveness, therefore need regularly the micro-moisture in the SF6 gas to be detected.
Test to the micro-moisture in the SF6 gas at present mainly is to use the little water tester of SF6, adopt the humidity sensor of import, and the verification of this humidity sensor is generally undertaken by provincial metrological service, used humidity generator price is more expensive, the verification expense is than higher, check-verifying period is also longer, causes enterprise's use cost to rise.
The utility model content
The technical problems to be solved in the utility model is: a kind of humidity generator is provided, and it obtains suitable satisfactory humidity gas by adjusting the flow of dried humid gas, and whether be used for the variation tendency of verification humidity sensor accurate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of humidity generator, has gas turnover pipeline, inlet end and outlet side at gas turnover pipeline are respectively arranged with diversion three-way and conflux threeway, one road outlet pipe of diversion three-way is provided with the dry gas flow accommodometer, be disposed with waterglass pipe and flux of moisture accommodometer that water is housed on another road outlet pipe, the outlet side of dry gas flow accommodometer and flux of moisture accommodometer is inserted the threeway of confluxing respectively.
For preventing gas backstreaming, lead at diversion three-way on the pipeline of waterglass pipe and on the pipeline of dry gas flow accommodometer outlet side and be respectively arranged with check valve, the pipeline of threeway outlet side of confluxing is provided with the sky glass tube, utilize water proportion greater than gas, the moisture that contains in the gas of giving vent to anger can be collected in the sky glass tube.
The beneficial effects of the utility model are, the utility model utilizes two flow-controlling meters to regulate to be passed through does, the flow of moisture, thereby obtains required humidity gas, because its used accessory is simple, easy for installation, so the also more existing humidity generator of price is cheap, and carry easily.

Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The 1. diversion three-ways 2. threeway 3. dry gas flow accommodometers 4. waterglass pipes 5. flux of moisture accommodometers 6. check valves 7. empty glass tubes that conflux among the figure
The specific embodiment
A kind of humidity generator as shown in Figure 1, has gas turnover pipeline, inlet end at gas turnover pipeline is provided with a diversion three-way 1, one road outlet pipe of diversion three-way 1 is provided with dry gas flow accommodometer 3, be used to regulate the dry gas flow that is flow through, be disposed with waterglass pipe 4 and flux of moisture accommodometer 5 that water is housed on another road outlet pipe, become the moisture that contains moisture behind the dry gas process waterglass pipe 4, moisture inserts the threeway 2 of confluxing that is arranged on gas turnover pipeline outlet side through flux of moisture accommodometer 5 backs again, simultaneously, the dry gas that flows through from dry gas flow accommodometer 3 also accesses to the threeway 2 of confluxing and mixes the back outflow with moisture, in addition in order to prevent to produce the gas backstreaming phenomenon, lead at diversion three-way 1 on the pipeline of waterglass pipe 4 and on the pipeline of dry gas flow accommodometer 3 outlet sides and be respectively arranged with check valve 6, from the mist that flow out threeway 2 outlet sides of confluxing because of containing a certain amount of moisture, so the pipeline of threeway 2 outlet sides of confluxing is provided with sky glass tube 7, utilize water proportion greater than gas, the moisture that contains in the gas of giving vent to anger can be collected in the sky glass tube 7.
During use, dry gas in the steel cylinder enters system from inlet end, through diversion three-way 1 separated into two parts, part process check valve 6 is to the waterglass pipe 4 that water is housed, the gas humidity that comes out from waterglass pipe 4 is bigger, again through entering the threeway 2 of confluxing behind the flux of moisture accommodometer 5, another part directly enters dry gas flow accommodometer 3, behind check valve 6, also enter the threeway 2 of confluxing, the dried wet mixture body in back that confluxes flows out through empty glass tube 7 backs, the many moisture that contain in the gas are then stayed in the sky glass tube 7, size according to the needed moisture of verification humidity sensor, adjust two flow-controlling meters, the humidity that obtains after this is calculated is exactly the humidity value of gas of giving vent to anger.
The utility model utilizes two flow-controlling meters to regulate to be passed through does, the flow of moisture, thereby obtains required humidity gas, simple in structure, easy to use.
