Power electrical transformer with good safety performance

Abstract

The invention discloses a power electrical transformer with good safety performance and relates to the technical field of power electrical transformers. The transformer comprises a transformer main body, three fixing frames and a plurality of cooling fins, wherein the three fixing frames are welded to a front end, a rear end and one side of the transformer body correspondingly, multiple cooling fins are evenly and fixedly arranged at the front end, the rear end and one side of the transformer body, a shell is fixedly arranged at a front end of the transformer body, an exhaust fan is fixedly arranged in the shell, a first bent pipe is fixedly arranged on one side of the shell, one end of the first bent pipe penetrates through one side of the shell and is arranged on the front side of the exhaust fan, the first bent pipe is fixedly arranged at an outer end of the transformer body, and a heat dissipation mechanism is arranged at a top end of the transformer body. The transformer is advantaged in that heat is absorbed through cooling fins, the cooling fins are cooled through wind power generated by the exhaust fan, meanwhile, collected rainwater is subjected to heat exchange, the evaporation rate of the rainwater is increased, heat of the transformer body is absorbed, then the transformer body is cooled, and safety is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric power transformers, in particular to a power electric transformer with good safety performance. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses. [0003] A power transformer is a necessary equipment for power transmission and distribution and power user distribution. A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several types of the same frequency. A device with different voltage (current) values. When the primary winding is supplied with alternating curr...

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides a power transformer with good safety performance, which absorbs heat through the heat sink, and the wind generated by the exhaust fan dissipates heat on the heat sink, and at the same time, the collected rainwater performs heat exchange, speeding up the evaporation rate of rainwater and absorbing the main body of the transformer. In order to solve the problem in the prior art that the transformer only dissipates heat independently through the heat sink, the heat dissipation effect is poor, high temperature easily damages the internal components of the transformer, and the safety is low
