a power transformer

Abstract

The invention discloses a novel power transformer. The novel power transformer comprises a power transformer body, a shell, a protection shell, a temperature compensation system, storage batteries andsingle chip microcomputers; a high-voltage group, a low-voltage group and heat dissipation sheets are arranged in the power transformer body; a first iron core, a first coil, high-voltage binding posts and a control chip are arranged in the high-voltage group; a second iron core, a second coil, low-voltage binding posts and a control chip are arranged in the low-voltage group; ventilating ports with protection nets are arranged on the left and right sides of the shell and the protection shell; ventilating ports with fans are arranged on the upper and lower sides of the shell and the protection shell; and a winding electroplating type multi-connecting-point electric pile, hot connecting points, cold connecting pints and temperature sensors are arranged in the temperature compensation system. The novel power transformer has the remarkable advantages as follows: by adoption of the temperature compensation system, the problems of incomplete pressure conversion and low efficiency caused byincreasing of the resistance due to a large amount of heat generated in the voltage transformation process can be solved; and by adoption of a sound insulation layer, sound generated in the machine operation can be lowered.

Description

technical field [0001] The invention relates to a transformer, in particular to a power transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. [0003] The power transformers currently on the market do not take into account that a large amount of heat is generated during operation during the transformation process, which leads to an increase in resistanc...
