Background technique
The insulation of oil-filled power equipment (such as transformer, reactor) is mainly by mineral insulating oil and leaching in the oil Organic insulating material is formed.Wherein mineral insulating oil, that is, transformer oil is a kind of fraction products of petroleum.Operating normally shape Under state, due to oil and solid insulation can gradually aging, rotten, minimal amount of gas can be decomposited.Occur inside power equipment When Superheated steam drier, discharging fault or dampness situation, the yield of these gases can increase sharply.Empirical evidence, oil dissolved gas Various composition content number and failure property and degree it is directly related.Therefore in equipment running process, periodic measurement Gas structural constituent and the content being dissolved in oil, for finding that Hidden fault existing for oil-filled power equipment inside has early Very important meaning.
Gas in transformer oil is separated from transformer oil first, is then fed into gas chromatograph and is carried out gas content And the detection of gas componant, gas need quantitatively to be sent into chromatograph.In the prior art, draw gas is quantified using syringe cylinder Injecting chromatograph, it is not only inconvenient for operation, but also quantitative inaccuracy.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of transformer oil abjection gas The quantitative automatic sampling device of body.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of transformer oil abjection gasometry automatic sampling apparatus, including sealing room, seal room upper opening, seal room Top is connected with pressing plate, and pressing plate is fixedly connected with sealing room, and pressing plate will seal the sealing of room upper opening.The inside of sealing room is equipped with Diaphragm, diaphragm are divided into upper cavity, lower chamber for room is sealed.
Lower chamber is airtight cavity, is filled with inert gas in lower chamber.Upper cavity is common by pressing plate, diaphragm and sealing room It surrounds.Air inlet, gas outlet are offered on pressing plate respectively, air inlet connects admission line, and admission line connects in transformer oil The gas separated is equipped with intake valve on admission line;Gas outlet connects outlet pipe, and outlet pipe connects gas-chromatography Instrument is equipped with air outlet valve on outlet pipe.Pressure sensor is installed on pressing plate.Pressure sensor protrudes into upper cavity, is used to Detect the pressure inside upper cavity.
Intake valve, air outlet valve and pressure sensor are electrically connected with control unit, control unit receive intake valve, air outlet valve and The feedback information of pressure sensor, and control the movement of intake valve, air outlet valve and pressure sensor.
The lower part side of the sealing room offers pre- inflating port, and plugging device is equipped at pre- inflating port, and pre- inflating port is used Carry out pre- filling with inert gas, is tightly blocked pre- inflating port using plugging device after the completion of inflation.
The diaphragm is made of elastic material.
The diaphragm is made of rubber material.
The intake valve, air outlet valve select solenoid valve.
The use principle of the utility model are as follows:
Under normal condition, the upper cavity and lower chamber pressure balance, diaphragm for sealing room are not deformed.
When work, intake valve is opened, closes air outlet valve, the gas isolated from transformer oil is pressurizeed by pressurizing device Afterwards, it is sent into the upper cavity of sealing room by admission line by air inlet, seals indoor setting diaphragm, the gas to be detected being filled with Diaphragm deflection is oppressed, diaphragm is pressed gradually downward, and the compressed volume of the inert gas of lower chamber becomes smaller.
Because pressure value is directly proportional to the amount of gas, according to amount preset pressure, pressure sensor needed for gas to be detected When detection reaches preset pressure, control unit is fed back to, control unit control closes intake valve, opens air outlet valve, outlet pipe Connect gas chromatograph, because being normal pressure in chromatograph, the intracorporal inert gas of cavity of resorption is compressed gas, therefore, in lower chamber by The inert gas of compression generates reaction force and oppresses diaphragm, and diaphragm squeezes the intracorporal gas to be detected of epicoele, makes gas to be detected It is extruded, is sent into chromatograph, diaphragm is gradually recovered original shape, and the gas to be detected of set amount enters chromatograph by gas outlet.
The utility model beneficial effect achieved is:
Gasometry to be detected can be automatically fed into gas chromatograph and detect by the utility model, compared with prior art, side Just quick, and more precisely.
