Problems solved by technology
The controller is generally composed of a controller, a matching device, and a secondary instrument. The cost is relatively high, but the actual application is less, and it is generally not connected to the non-electric control circuit, and because the mechanical part is easy to rust, the potentiometer in the controller is easily damaged. , the meter structure is complex, expensive, and difficult to repair, which seriously affects the local meter indication and the temperature display of the monitoring system

The invention discloses a transformer temperature control method. The method comprises the steps of collecting the three-phase pile head temperature of a transformer; acquiring the oil surface temperature; calculating the unit time heat dissipating capacity of the contact part of the bottom surface of the transformer and a supporting part; obtaining the calibration temperature of an oil surface temperature calibration sensor; judging whether the difference between the oil surface temperature and the calibration temperature exceeds the standard or not; calculating the transformer winding temperature and the transformer life; judging whether the transformer life exceeds a preset life value; sending the predicted life value of the transformer to a cloud server, and carrying out life cycle classification on the transformer by the cloud server; enabling the cloud server to calculate the heat dissipating capacity of the transformer shell and the cooling coefficient of the transformer; acquiring the wind speed of a transformer cooling fan; enabling a controller to correct the winding temperature of the transformer according to the collected wind speed of the cooling fan and the cooling coefficient of the transformer; and calculating the heat dissipating capacity of the transformer according to the winding correction temperature of the transformer.
Description
technical field [0001] The invention relates to the field of transformers, in particular to a transformer temperature control method and a transformer. Background technique [0002] The power transformer is an important electrical equipment in the power system, and its operation status affects the overall safety and reliability of the power system. Transformer insulation aging due to over-temperature operation of windings accounts for a large proportion of transformer failures in power systems. Therefore, the measurement of transformer oil temperature is extremely important for preventing transformer failures. At present, the measurement of power transformer oil temperature mainly depends on the transformer thermometer and its supporting related devices. In the long-term operation and use process, the accuracy of the thermometer will decrease with the use time, resulting in errors or even errors in the detection results, thus losing effective monitoring of the transformer t...
