Abstract

The invention discloses a dry-type electric transformer. The dry-type electric transformer comprises a case body. A first vent hole and a second vent hole are arranged in the case body in the manner of longitudinal symmetry. An inner cavity of the first vent hole is equipped with an air suction fan through a support. An inner cavity of the second vent hole is equipped with an air discharge fan through a support. A support board is arranged at the bottom of an inner cavity of the case body. Heating resistance wires are installed in the inner cavity of the support board at equal intervals. Through an inner cavity of a first water tank, a first water pipe is arranged. Additionally, the other end of the first water pipe is connected to a second water tank. A second water pipe is arranged in aninner cavity of the second water tank. Additionally, the other end of the second water pipe is connected to the first water tank. Water in inner cavities of the first water tank and the second watertank conveniently flow in order to decrease temperature in the case body. The normal lives of people are prevented being affected when noises generate during operation of coil windings. The dry-type electric transformer is highly functional. Therefore, application effect and application benefits are ensured. The dry-type electric transformer is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of dry-type power transformers, in particular to a dry-type power transformer. Background technique [0002] Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. The transformer is a device that transforms AC voltage, current and impedance. , when there is alternating current in the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil. The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the s...
