Description
Technical field
The utility model relates to a kind of Gas in Oil of Transformer on-line monitoring system device, especially a kind of simple in structure, control is reliable, be easy to safeguard the Gas in Oil of Transformer on-line monitoring system carrier gas bottle automatic switching control equipment of can reduce labor strength, increasing work efficiency.
Background technology
The Gas in Oil of Transformer on-line monitoring system is to the content on-line monitoring of the dissolved gas in the transformer used oil (hydrogen, carbon monoxide, methane, ethane, ethene, acetylene etc.), analyzes and carry out the equipment of fault diagnosis, can be used for the oil-immersed and high-voltage equipment such as power transformer, arc furnace transformer, reactance transformer and mutual inductor.The Gas in Oil of Transformer on-line monitoring system all is provided with oily cycling element, degas module, gas sample separative element, gas sample signal gathering unit, data analysis unit and control module mostly at present.During installation, the oil-in of oily cycling element and the fuel tank of oil return opening and transformer are joined, make the oil circuit that forms circulation between pick-up unit and the oil tank of transformer.During monitoring, at first open inlet valve and oil return valve and start circulating oil pump, the oil in the degas module degas chamber is replaced into the oil of transformer inside, afterwards the gas in the oil is deviate from; The gas of deviating from enters in the chromatographic column of gas sample separative element and separates, and with converged by the carrier gas of carrier gas bottle to chromatographic column input, formation enters in the gas sample signal gathering unit with the gas at carrier gas interval, by sensor each concentration of component value in the gas is converted into corresponding electric signal, by by data transmission wires signal being inputed to data analysis unit after the analog to digital conversion, data analysis unit is analyzed the signal that obtains, output (uploading) analysis result, export simultaneously control signal, control corresponding warning device and each way solenoid valve etc.Because existing carrier gas is to be inputted to chromatographic column in turn by reduction valve separately respectively by two carrier gas bottles, need the operator to observe at any time, after finding that one bottle of carrier gas is finished, just need to manually be replaced by another bottle carrier gas, exist the problem that operator's labour intensity is high, waste time and energy, affect work efficiency.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical matters of prior art, provide a kind of simple in structure, control is reliable, the Gas in Oil of Transformer on-line monitoring system carrier gas bottle automatic switching control equipment that can reduce labour intensity, increase work efficiency.
Technical solution of the present utility model is: a kind of Gas in Oil of Transformer on-line monitoring system carrier gas bottle automatic switching control equipment, be provided with housing, the left and right sides is respectively equipped with the first air chamber and the second air chamber in the housing, described the first air chamber is provided with the first carrier gas inlet and the first pressure probe, described the first air chamber is provided with the second carrier gas inlet and the second pressure probe, the first air chamber and the second air chamber all join by self-sustaining valve and carrier gas efferent duct, output and the control circuit of described the first pressure probe and the second pressure probe join, control circuit output signal control self-sustaining valve and warning circuit.
The utility model can automatically detect carrier gas bottle pressure and realize the automatic switchover carrier gas according to the pressure signal that detects, after being finished, last bottle carrier gas automatically sends alerting signal, remind the staff to change carrier gas, simple in structure, control is reliable, be easy to safeguard, can reduce labor strength, increase work efficiency.
