Temperature control type transformer and control method thereof

Abstract

The invention discloses a temperature control type transformer and a control method thereof. The temperature control type transformer comprises a water tank and a transformer body, cooling fins used for cooling are arranged on the two sides of the transformer body, and mounting assemblies used for mounting the water tank are arranged on the two sides of the lower end face of the water tank; two mounting vertical rods are fixedly connected to the two side faces of the water tank, the transformer body is mounted between the upper ends of the mounting vertical rods on the two sides of the water tank, an oil pump is fixedly connected to the lower end of one side of the transformer body, and the input end of the oil pump communicates with the interior of the transformer body; and according to the invention, the temperature sensor is arranged, the temperature of oil in the transformer body can be monitored, and when the transformer body works in a full-load mode to generate high temperature, the water tank can be rapidly cooled through spraying of the cooling fins and circulating water cooling and air cooling of the oil in the transformer body; the transformer body is prevented from working in a high-temperature area for a long time.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a temperature-controlled transformer and a control method thereof. Background technique [0002] Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). The main functions of transformers are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc., and can be divided into power transformers and special transformers according to their uses. Oil-immersed transformers use oil as the main insulation method of the transformer and rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation. [0003] In existing transformers, oil circulation and air cooling are generally used to dis...

AI Technical Summary

Problems solved by technology

[0003]In the existing transformers, oil circulation and air cooling are generally used to dissipate heat from the transformer. However, when the transformer is working at full load, the temperature inside the transformer will rapidly increase. At this time, it is difficult to reduce the temperature of the transformer oil by the oil circulation plus air cooling heat dissipation method, and it is difficult to effectively take away the heat inside the transformer. The heat dissipation effect is limited, and the transformer is kept at high temperature for a long time, which greatly increases the failure rate of the transformer and seriously affects the service life of the transformer. Based on the above-mentioned problems, we provide a temperature-controlled transformer and its control method
