Abstract
The invention discloses a diaphragm type oil conservator for a transformer. The diaphragm type oil conservator comprises a cabinet body, a diaphragm, a discharging plug, a viewing window, a water draining plug, a connecting pipe, a sewage collecting box, an oil pipe joint, a semicircular flange, a flange sealing element and a gas relay, wherein the cabinet body consists of two half-cylindrical structures; two half cylinders are connected with each other through an upper half semicircular flange and a lower half semicircular flange; the flange sealing element is arranged between the upper half semicircular flange and the lower half semicircular flange, and is used for enhancing the sealing strength of the oil conservator; the periphery of the diaphragm is press-mounted between upper and lower cabinet edges; the inner side of the diaphragm is attached to an oil surface; the outer side of the diaphragm is communicated with the atmospheric air. According to diaphragm type oil conservator for the transformer provided by the invention, adaptability to a transformer of over 8,000 kV.A is enhanced by taking the flange sealing element in the semicircular flanges as a second seal, and the transformer is better protected through the gas relay.
