Abstract

The invention discloses a transformer oil level gauge calibration method and a related device. The method comprises the following steps: acquiring the initial oil level height of an oil conservator and the initial oil level height of an external hose; after the oil conservator is inflated and boosted through the pressure regulating tool, the boosted oil level height of the oil conservator and the oil level height of the corresponding boosted external hose are obtained; calculating an oil level pressure coefficient according to the initial oil level height, the initial external hose oil level height, the boosting oil level height and the boosting external hose oil level height; under the condition that expansion deformation of an expander of the oil conservator is prevented, the oil level height of the hose at the verification point is calculated according to the initial oil level height, the initial oil level height of the external hose, the oil level pressure coefficient and the oil level height of the verification point; and according to the oil level height of the hose at the verification point, inflation boosting or exhaust depressurization verification is carried out on the expander of the oil conservator, and a verification result is obtained. The technical problems of low verification universality and efficiency caused by long time consumption, large workload and high cost in the prior art can be solved.

Description

technical field [0001] The present application relates to the technical field of transformers, in particular to a method for calibrating a transformer oil level gauge and related devices. Background technique [0002] Transformer oil plays the role of insulation and cooling in the operation of oil-immersed transformers. If the oil level of the transformer is too high, it may cause excessive pressure in the oil tank at high temperature or under heavy load, resulting in oil overflow or the action of the pressure relief valve; if the oil level of the transformer is too low, the high pressure part may lose the protection of oil and be exposed Cause breakdown, discharge, and transformer damage; at the same time, the oil level can also reflect the sealing condition of the oil tank, which is convenient for timely detection of oil leakage or oil leakage. Therefore, timely and accurate monitoring of the oil level is very important for the safe operation of the transformer. [0003]...
