Abstract
The invention provides an energy-saving and environment-friendly dry-type power transformer, belongs to the technical field of transformer equipment and solves the problem of poor heat dissipation performance of a conventional dry-type power transformer. The energy-saving and environment-friendly dry-type power transformer comprises a tank body and a door body arranged on the tank body, wherein a supporting base is arranged at the bottom of the tank body; an alarm and two proximity switches are arranged at the top of the tank body; the two proximity switches are connected in parallel and are in electrically-controlled connection with the alarm; a plurality of uniformly and vertically arranged coil windings are arranged in the tank body; each coil winding comprises an iron core, a low-voltage coil and a high-voltage coil; a first longitudinal ventilating duct is formed between every two coil windings; a ventilator is arranged at the bottom of each first longitudinal ventilating duct; the tops of the coil windings are connected with an upper fixed part; the bottoms of the coil windings are connected with a lower fixed part; two support blocks are arranged on the lower end surface of the lower fixed part; a second longitudinal ventilating duct is formed between the two support blocks. The energy-saving and environment-friendly dry-type power transformer has the advantages of simple structure and excellent heat dissipation performance.
Description
technical field [0001] The invention belongs to the technical field of transformer equipment, and relates to a dry-type power transformer, in particular to an energy-saving and environment-friendly 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...
