Abstract

The invention relates to a power transformer, which comprises an iron core, a primary winding, a secondary winding and a wrapping post, wherein the primary winding and the secondary winding are wound on the wrapping post; both the primary winding and the secondary winding are connected with a connecting terminal; at least two turns of primary winding and secondary winding are arranged; each turn comprises at least two coils; and a ventilating gap is formed between the turns. According to the power transformer, the heat dissipation effect of the transformer is improved, safe, normal, high-efficiency and durable operation of the power transformer is guaranteed, and the linear diameter of the windings can be reduced to reduce the cost.

Description

technical field [0001] The invention relates to a transformer, in particular to a 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 used at all levels to meet the needs of power consumption. In short, both step-up and step-down must be done by the transformer. In the process of electric energy transmission in the power system, two parts of voltage and power will inevitably be lost. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. Using the transformer to increase the voltage reduces the power transmission loss. [0003] The transformer is composed of two or more coil windings wound on the same ir...
