In addition, the Main Function of transformer oil chromatographic online monitoring device examining system is that the ruuning situation monitoring transformer in real time prevents paroxysmal fault, current monitoring device tests once for one to two days, and can not realize thinking in one day to carry out test analysis to electric power transformer oil tens of times, so just be difficult to the ruuning situation of real-time monitoring power electric transformer, be difficult to the catastrophic discontinuityfailure finding power transformer.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of transformer oil chromatographic on-line monitoring special-purpose air generator, and this air generator volume is little, and its gas purity produced is high and measure unrestricted, and this device can manpower-free be safeguarded.
In order to solve the problem, the technical solution of the utility model is: a kind of transformer oil chromatographic on-line monitoring special-purpose air generator, its design feature is, this air generator comprises air compressor, primary purifying unit, retaining valve, air accumulator, reduction valve, secondary purification unit and M8 × 1 joint, air in described air compressor input environment, the input end of primary purifying unit is connected with the output terminal of air compressor and exports purified gas, export gas and enter air accumulator by retaining valve, air accumulator is connected with secondary purification unit by reduction valve, and M8 × 1 joint is connected with secondary purification unit output terminal.
Wherein, surrounding air is transported in equipment by air compressor, primary purifying unit tentatively removes particle, moisture and carbon dioxide in air, retaining valve can prevent air return, air accumulator then prevents air compressor frequent starting, reduction valve makes the output pressure of air held stationary, and secondary purification unit then removes methane, carbon dioxide and particle further, makes output gas meet the technical requirement of transformer oil chromatographic on-line monitoring.
Preferably, described primary purifying unit comprises air strainer and desorption pipe, and the gas output end of described air strainer is connected with the input end of desorption pipe.The particle of air strainer removing more than 20um, the water in desorption pipe removing gas and carbon dioxide.
Preferably, described secondary purification unit comprises except hydrocarbon device, purge drying pipe, tensimeter, flow controller and accurate filter, wherein gas enters purge drying pipe after except hydrocarbon device removing methane gas, the output terminal of purge drying pipe is connected with tensimeter, and the tensimeter other end is connected with flow controller, gas is exported by flow controller and enters accurate filter to remove the particle of more than 0.01um.The effective carbon dioxide removed in gas of described purge drying, tensimeter and flow controller monitor gas output pressure, thus make gas export certain flow.
Compared with prior art, this uses novel beneficial effect to be: substitute bottled high pure air with air generator instrument, methane gas in surrounding air is about 0.1uL/L that 1.7uL/L falls and following, carbon dioxide are about 0.0uL/L that 397uL/L falls, particle falls 0.01um and following, gas flow is unrestricted, can repeatedly test the short time, realize the test of tens of times in a day of transformer oil chromatographic on-Line Monitor Device, the ruuning situation of real-time monitoring power electric transformer.Manpower-free safeguards, normally run for many years after installation, purity is high, and meet the technical requirement of chromatography online monitoring system for transformer oil completely, volume is little, can be built in transformer oil chromatographic on-Line Monitor Device cabinet, does not take on-the-spot more space.
