Automatic cooling device for transformer

Abstract

The invention discloses an automatic cooling device for a transformer. A partition plate is horizontally arranged in a device shell body, and the device shell body is divided into a transformer installing bin on the upper part and a cooling bin on the lower part; an air inlet and a plurality of heat dissipation holes are formed in the device shell body; the air inlet is formed in the lower part ofthe partition plate; the transformer is arranged on the partition plate and is located in the transformer installing bin; a recycling water box is arranged in the cooling bin; one end of a water inlet pipe is connected with an exterior water source, and the other end of the water inlet pipe extends into the device shell body and is connected with the upper part of the recycling water box; a waterinlet control valve is arranged on the pipeline, on the outer side of the device shell body, of the water inlet pipe; one end of a water discharging pipe is connected with the lower part of the recycling water box, and the other end of the water discharging pipe extends out of the device shell body and is connected with a water discharging system; and a water discharging control valve is arrangedon the pipeline, on the outer side of the device shell body, of the water discharging pipe. According to the automatic cooling device for the transformer, cooling and heat dissipation can be automatically conducted according to the temperature of the transformer, the cooling efficiency is high, the temperature cooling effect is great, heat dissipation is ensured and at the same time energy is saved due to intelligent heat dissipation and recycling of cooling water, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of transformer cooling devices, in particular to an automatic cooling device for transformers. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] In electrical equipment and wireless circuits, transformers are often used for step-down voltage, matching impedance, safety isolation, etc. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains the same, but the amount of magnetic flux intersecting the coil is different. Ch...
