Description
Technical field
The present invention relates to oil immersed power transformer measuring and adjusting field, is a kind of oil immersed power transformer pernicious gas separator.
Background technology
The root that oil immersed power transformer insulation oil dissolved gas mainly produces is: when certain fault of the inner existence of transformer, and near oil the trouble point and the solid insulating material gas that cracking produces under fuel factor or electrical fault stress effect.Oil and solid insulating material decompose to produce under the effect of hot or electrical fault has hydrogen, methane, ethane, acetylene, ethene, carbon monoxide and carbon dioxide to the harmful gas of transformer; These gases can endanger transformer and normally move, and it is imperative effectively to reduce in the oil pernicious gas content.
Existing power system mainly is to change transformer insulation oil through the back of stopping transport to the harmful gas removing of transformer oil; Though this method is effective; But stoppage in transit itself will bring a lot of losses; And generally to when big light maintenance, could stop transport, during this in oil pernicious gas also can constitute a threat to the transformer safe operation.At present also useful transformer insulation oil is carried out the device that on-line cleaning is got rid of well cuts and pernicious gas, but it mainly is to lean on experience, irregularly carries out, and can not carry out in real time, the while cost is also higher.A kind of rational in infrastructure, practical, oil immersed power transformer pernicious gas separator that cost is low is provided; Under the situation that transformer is not stopped transport; Pernicious gas is that those skilled in the art are expected to solve always in the timely online removing transformer insulation oil, but still unsolved technical barrier.
Summary of the invention
Technical problem to be solved by this invention is, prior art is improved and innovated, provide a kind of rational in infrastructure, practical, cost is low, can effective online removing transformer insulation oil in the oil immersed power transformer pernicious gas separator of pernicious gas.
The technical scheme that solves its technical problem employing is: a kind of oil immersed power transformer pernicious gas separator; It is characterized in that: transformer insulated fuel tank is connected with conservator; Conservator is connected with the Oil-gas Separation bucket; The Oil-gas Separation bucket is connected with the gas collecting box through flexible pipe, and gas collecting box gas outlet is connected with aspiration pump with motor-operated control valve; Said Oil-gas Separation bucket comprises staving, on staving, is connected with bung, and support tube is set in staving, and one deck polymeric membrane for separation at least is set in support tube; Built-in pressure sensor, data collecting card and the control computer of said gas collecting box is electrically connected in proper order, and the control computer is electrically connected with motor-operated control valve and aspiration pump.
Oil immersed power transformer pernicious gas separator of the present invention; The unidirectional osmosis principle of utilizing polymeric membrane to divide for oil gas; Under suitable vacuum state; Pernicious gas can come out through permeable polymeric film in the oil, and insulating oil can't pass through polymeric membrane, thereby can pernicious gas be separated with insulating oil; Can the pernicious gas of separating in the transformer insulation oil be collected in the gas collecting box; Pernicious gas collecting box pressure maintains in the scope less than the transformer internal pressure all the time; Usually pressure limit is 1000Pa to 8000Pa, when pressure differential starts motor-operated control valve and aspiration pump during less than 1000Pa, in time through aspiration pump it is discharged; Thereby timely online eliminating pernicious gas is guaranteed the safe operation of transformer; Have rational in infrastructure, practical, low cost and other advantages.
Description of drawings
Fig. 1 is an oil immersed power transformer pernicious gas separator structural representation.
Fig. 2 is an Oil-gas Separation barrel structure cross-sectional schematic among Fig. 1.
Among the figure: 1 transformer insulated fuel tank, 2 conservators, 3 Oil-gas Separation buckets, 4 flexible pipes; 5 gas collecting boxs, 6 pressure sensors, 7 aspiration pumps, 8 data collecting cards; 9 control computers, 10 motor-operated control valves, 31 stavings, 32 ground floor molecular separation membranes; 33 second layer polymeric membrane for separation, 34 bungs, 35 support tubes.
The specific embodiment
With reference to the accompanying drawings the present invention is further specified.
The transformer insulated fuel tank 1 of oil immersed power transformer pernicious gas separator of the present invention is connected with conservator 2, above conservator 2, has a hole, and Oil-gas Separation bucket 3 is installed in the top, hole, and staving 31 is welded on the top, hole of conservator 2, and its somewhat larger in diameter is in the diameter in hole.Support tube 35 is set in staving 31, one deck polymeric membrane for separation at least is set in support tube 35, two-layer polymeric membrane for separation is set in this specific embodiment, be i.e. ground floor polymeric membrane for separation 32 and second layer polymeric membrane for separation 33.On staving 31, be connected with bung 34; The venthole of bung 34 is connected with flexible pipe 4; The other end of flexible pipe 4 is connected with the air intake of gas collecting box 5; The gas outlet of gas collecting box 5 is connected with motor-operated control valve 10, aspiration pump 7, and gas collecting box 5 built-in pressure sensor 6, data acquisition board 8, control computer 9 orders are electrically connected, and control computer 9 is electrically connected with motor-operated control valve 10, aspiration pump 7.Polymeric membrane for separation adopts hollow-fibre membrane.
During work; By pressure sensor 6 measurement gas collecting boxs 5 internal pressures that place in the gas collecting box 5, pass to control computer 9 through data collecting card 8, when recording gas collecting box 5 internal pressures and be lower than the not enough 1000Pa of the pressure differential of the pressure in the transformer; Control computer 9 sends instruction to motor-operated control valve 10 and aspiration pump 7; Motor-operated control valve 10 is opened, and aspiration pump 7 work are bled to gas collecting box 5; When recording pressure differential that gas collecting box 5 internal pressures are lower than the pressure in the transformer greater than 8000Pa; Control computer 9 sends instruction to motor-operated control valve 10 and aspiration pump 7; Motor-operated control valve 10 is closed, and aspiration pump 7 quits work, and the work of bleeding of gas collecting box 5 is stopped.So circulation just can in time be got rid of the pernicious gas in the transformer insulation oil.
Electronic control air bleeding valve 10, aspiration pump 7, pressure sensor 6, data collecting card 8, control computer 9, polymeric membrane for separation are the common product in market, and monitoring is the technology that computer realm is known with the control software programming.
