Transformer with circulating liquid cooling function

Abstract

The invention discloses a transformer with circulating liquid cooling function. The transformer comprises a coil and an iron core, wherein the iron core comprises a core column and an iron yoke, the coil is coaxially sleeved on the core column, the core column is fixedly connected with the iron yoke, the coil comprises a high-voltage coil and a low-voltage coil, the low-voltage coil is arranged outside the core column in a sleeving mode, the high-voltage coil is arranged outside the low-voltage coil in a sleeving mode, the transformer further comprises a plurality of cooling pipelines, the cooling pipelines are arranged in the low-voltage coil and the core column respectively, each cooling pipeline is provided with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipes are connected with a cooling liquid source, the liquid outlet pipes are connected with a liquid outlet, and cooling water enters the cooling pipelines through the liquid inlet pipes and is discharged through the liquid outlet pipes. According to the transformer, the cooling pipelines are arranged in the low-voltage coil and the core column, so that the low-voltage coil and the core column are filled with the cooling liquid, and the cooling liquid continuously and circularly flows in the cooling pipelines to effectively absorb the heat generated by the transformer in air so as to effectively cool thetransformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer with a circulating liquid cooling function. Background technique [0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change the AC voltage. Transformers generate a lot of heat during operation. When the transformer is working, more heat is generated, and the temperature of the iron core easily exceeds the specified value of the national standard. When the temperature of the iron core exceeds the specified value of the national standard for a long time, it is easy to cause rapid aging of the insulation layer of the iron core, shorten the life of the iron core, and then affect the normal operation of the transformer. If the heat in the transformer cannot be removed in time, the accumulated heat will easily cause a fire. Therefore, it is very important to cool and dissipate the transformer in time. [0003] Tr...

Problems solved by technology

However, the fan is installed outside the transformer, and it is slow to evacuate the heat in the transformer, so it cannot dissipate heat quickly.

In addition, if multiple fans work for a long time, they will consume a large amount of electricity and generate additional heat and noise, which is not conducive to energy saving and environmental protection, but also increases the burden of heat dissipation, and the heat dissipation effect still cannot meet the demand.
