Principle of operation
When the oil-immersed transformer normally works, the oil inlet pipe 35 and the oil outlet pipe 34 are communicated with each other in the fan-shaped cavity wall 27, the fan-shaped cavity wall 27 is connected with the sealing connection groove body 33 through the sealing sliding block 28 to seal the inside of the fan-shaped cavity wall 27 with the outside, oil is pumped in the box body 10 through the oil hole connecting pipe 19 by the oil pump machine 44 to flow into the fan-shaped cavity wall 27 and then flow back to the box body 10 through the oil inlet pipe 35, the circulation is performed, the first pump machine 36 does not work at the moment, and the thermosensitive memory rod 26 is in a bending state at the moment.
When the volume of the transformer oil expands or decreases along with the temperature of the oil, the oil quantity is adjusted through the flexible film 31, the effect that the transformer oil tank is filled with the oil frequently is guaranteed, the flexible film 31 is extruded to protrude outwards when the oil expands, and the flexible film 31 contracts inwards when the volume of the oil decreases.
When the performance of the transformer oil is reduced, the temperature in the transformer is overhigh, the oil liquid continuously expands, the soft film 31 protrudes outwards to enable the heat conduction block 32 to be contacted with the thermosensitive memory rod 26, the oil temperature is transmitted to the thermosensitive memory rod 26 through the heat conduction block 32 to enable the thermosensitive memory rod 26 to be heated and straightened, after the thermosensitive memory rod 26 is straightened, the conduction interface 25 is inserted into the conduction groove seat 23, the rotary connection block 21 is electrified and rotated to drive the rotary shaft 22 to rotate to enable the fan-shaped cavity wall 27 to rotate to a certain distance to be hermetically connected with the sealed connection groove body 33 on one side, meanwhile, the oil inlet pipe 35 is communicated with the outer side of the fan-shaped cavity wall 27 in the oil change box 12 to carry out oil change operation, or when the transformer oil is deteriorated, the pH value of the transformer oil is detected through the acid-base detector 29, when the problem is detected, the feedback motor 30 feeds back to the driving motor 38, the rotary shell 20 is controlled by the driving motor 38 to enable the rotary connection block 21 to rotate, and performing oil change operation.
When the transformer oil insulation effect is invalid, the current detection module 37 senses the internal current and feeds the internal current back to the driving motor 38, so that the transformer stops working, and meanwhile, the fan-shaped cavity wall 27 rotates to pump new oil through the first pump 36 for replacement.
When the oil well pump 44 is controlled by pressing the manual button 39 during manual maintenance, the oil well pump 44 is driven by the manual button 39 to switch the output port to be communicated with the temporary oil storage tank 52, the transformer oil flows into the expandable sealing bag in the temporary oil storage tank 52 through the oil well pump 44 to be filled, the expansion rod 55 can be lifted upwards after the filling, when the extrusion plate 56 extrudes the expandable sealing bag, the transformer oil is in contact with the top oil block 58 to be extruded, and redundant gas in the transformer oil is discharged through the exhaust hole 60, the oil absorption cotton 59 can prevent the hydraulic oil from seeping and prevent external gas from entering the temporary oil storage tank 52, and after the maintenance, the hydraulic oil in the expandable sealing bag flows back into the tank body 10 through the oil inlet pipe 35 through the oil outlet pipe 34.
When oil is changed, oil in the box body 10 is pumped out through the oil pump 44, because no other passage is arranged in the fan-shaped cavity wall 27 at the moment, the internal pressure is increased, the second one-way valve body 50 is opened to flow the waste oil into the elastic thin bag 47 through the oil outlet connecting pipe 45, the elastic thin bag 47 is gradually filled, meanwhile, the elastic thin bag 47 discharges the air in the waste oil storage box 46 outwards through the waste oil box exhaust hole 48, the oil inlet pipe 35 is communicated with the new oil storage box 61, the new oil in the new oil storage box 61 is reduced through the oil in the box body 10 to form negative pressure, the new oil flows into the oil inlet pipe 35 through the new oil box connecting pipe 66 and is filled into the box body 10, the filter screen 67 can filter the new oil, impurities in the new oil are prevented from entering the box body 10, the new oil can be effectively separated from the old oil through the negative pressure generated by pumping out the waste oil, and the new oil and the waste oil are reduced to be mixed, effectively prolonging the service life of the transformer oil.
When new oil flows out, the sealing compression bag 65 contracts, the oil delivery plate 63 is lifted upwards, and when the new oil in the new oil storage tank 61 is lower than a certain value, the oil delivery plate 63 extrudes the oil quantity detection rod 69 to enable the oil quantity warning rod 70 to move upwards and warn maintenance personnel outwards to remind the maintenance personnel of adding new oil.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
