Description
Technical field
The utility model relates to the oil immersed power transformer field, is a kind of oil immersed power transformer oil changing device.
Background technology
The quality of the insulation oil of oil immersed power transformer is directly connected to the fail safe and the reliability of transformer operation; The power transformer operation characteristic has determined it to be in operation can produce all gases, when accident, more can produce a large amount of gases, and these gas majorities are dissolved in the insulating oil; Can make degradation of insulation; Along with transformer increases running time, also have a lot of impurity in the insulating oil and decompose therein simultaneously, the impurity of these gases all can injure the safe operation of transformer.
The existing existing oil quality analysis software that oil is carried out on-line monitoring; Can understand the oily situation of insulation at any time; But oil immersed power transformer generally operates in the high voltage rank, is difficult in not stop its ruuning situation and go down to change insulating oil, and the transformer overwhelming majority that changes oil is after transformer is stopped transport; Change by the maintainer is artificial; And transformer is stopped transport and can be had influence on the industrial and agricultural production of its supply district, therefore, how is not stopping and influencing that to change insulating oil under the oil immersed power transformer ruuning situation be problem demanding prompt solution.
Summary of the invention
The utility model technical problem to be solved is, prior art is improved and innovated, and provides a kind of transformer under the situation of not stopping transport, at any time by artificial or change the oil immersed power transformer oil changing device of insulating oil automatically.
The technical scheme that solves its technical problem employing is: a kind of oil immersed power transformer oil changing device; It is included in the built-in transformer insulated fuel tank of oil immersed power transformer and is connected through communicating pipe with the transformer insulation oil conservator; It is characterized in that: also comprise the car of changing oil; High position at the vehicle carriage of changing oil is provided with the fresh oil filler tank; Low level at the vehicle carriage of changing oil is provided with old oily collection box; The bottom of described fresh oil filler tank is connected with communicating pipe through second by-pass valve control, and described old oily collection box reaches the transformer oil sample valve that is provided with in transformer insulated fuel tank bottom and is connected with transformer insulated fuel tank bottom through first by-pass valve control, and described fresh oil filler tank is connected through oil pump with described old oily collection box.
Said first by-pass valve control, second by-pass valve control, transformer oil sample valve and oil pump all are connected with the computer input port through the control line interface.
The oil immersed power transformer oil changing device of the utility model can be realized changing oil under the situation that oil immersed power transformer is not stopped transport, and can realize changing oil automatically through computer control, and its operating efficiency is high.
