According to the provisions of the Ministry of Standards JB / T10112-1999, the service life of this oil pump is five years, that is, after the oil pump has been used for five years, the power department must cut off the power to replace the pump, which will inevitably result in power failure and human, material and material resources required for replacement. In addition, there is a hidden danger of oil leakage between the pump body and the base, which affects the smooth operation of the transformer

The invention relates to a transformer oil pump of power-plant used to constrain the oil circulation cooling in great large-scale and medium size transformer, rectiformer, reactor, and electric locomotive transformer. It includes pump body, impeller, electric machine, base plugger, connection box, sealing piece, and so on; it uses octapole disk type electric machine, and pairing bearing with centripetal thrust force; it encapsulates by electric welding between oil pump body and plugger, arbor and plugger, it can decrease synchronous speed 250r / min, decrease buzz 5-10dB, prolong service life.
Description
technical field [0001] The invention relates to a transformer oil pump used in large and medium-sized transformers, rectifier transformers, reactors and electric locomotive transformers for forced oil circulation cooling power devices. Background technique [0002] The existing transformer oil pump mainly includes pump body, impeller, motor, base, plug cover, junction box and sealing connector, etc. The motor is generally a six-pole disc motor with a synchronous speed of 1000r / min. Bolt on. According to the provisions of the Ministry of Standards JB / T10112-1999, the service life of this oil pump is five years, that is, after the oil pump has been used for five years, the power department must cut off the power to replace the pump, which will inevitably result in power failure and human, material and material resources required for replacement. In addition, there is a hidden danger of oil leakage between the pump body and the base, which affects the smooth operation of the t...
