Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, to an efficient heat dissipation transformer applied to thermal power plants. Background Technique

[0002] A transformer refers to a device that uses the principle of electromagnetic induction to change the AC voltage. Transformers can be divided into power transformers and special transformers according to their uses. Power transformers are mainly used in power transmission and distribution lines to change the magnitude of the AC voltage to meet the needs of different users. Special transformers are used in special fields such as smelting, electroprocessing, electric drive, communication, and automatic control. Its main components are the primary coil, secondary coil, and iron core. The main functions of a transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, etc. Transformers are basic equipment for power transmission and distribution and are widely used in industries, agriculture, transportation, urban communities, and other fields.

[0003] Currently, the main transformers applied to thermal power plants are step-up transformers. Their main function is to step up the electricity generated by the generator to the grid voltage and then connect the generated electricity to the grid. Since the temperature inside the thermal power plant is relatively high and the transformer will lose some energy in the form of heat during the step-up process, the transformers applied to thermal power plants usually operate in a high-temperature state. Over time, the components of the transformer are prone to aging and damage, affecting the normal service life of the transformer. In view of this, we propose an efficient heat dissipation transformer applied to thermal power plants. Content of the Utility Model

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model designs a water storage component, a cooling component, a heat exchange component, a heat absorption component and a fan component.
