Four-split dry-type transformer with intelligent temperature control function

Abstract

According to the four-split dry-type transformer with the intelligent temperature control function, a driving block, a rotating shaft, fan blades, a local gear, a reciprocating frame, a connecting rod, an air guide cover, an air guide plate, a first pull rod, a second pull rod and a sliding block are arranged to be matched with a temperature sensor for use, so that the four-split dry-type transformer has the intelligent temperature control function, and air can be blown in the front-back direction in a prefabricated cabin; the high-voltage coil adopts a non-split structure, so that the height of the product is greatly reduced, the internal structure and the winding process of the high-voltage coil are simplified, the heat dissipation effect is improved, the air in the prefabricated cabin is in full contact with the circulating heat dissipation pipe, and the heat dissipation effect is improved, and meanwhile, the exhaust fan is matched to enable the air to flow, so that the heat dissipation is better, and the temperature in the prefabricated cabin is controlled. And a grouping connection mode is adopted in the low-voltage coil, so that each group of low voltage has consistent short-circuit impedance, split operation is ensured, the product height is reduced, and the assembly process is simplified.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a four-split dry-type transformer with an intelligent temperature control function. Background technique [0002] A transformer is a static electrical equipment used to transform AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses; the safe operation and service life of dry-type transformers depend to a large extent on the safety and reliability of the transformer's safety winding insulation. The winding temperature exceeds the insulation tolerance temperature and the insulation is damaged, which is one of the main reasons for the transformer not to work normally. Therefore, the heat dissipation of the transformer is very important. Th...

AI Technical Summary

Problems solved by technology

The insulation damage caused by the winding temperature exceeding the insulation tolerance temperature is one of the main reasons why the transformer cannot work normally. Therefore, the heat dissipation of the transformer is very important. The temperature of the external environment will also affect the temperature inside the transformer. When the weather is hot, it is necessary to The transformer is continuously dissipated. However, in winter, due to the low external ambient temperature, the transformer can be slightly dissipated or even need not start the fan to dissipate heat. The change of temperature affects the heat dissipation effect of the transformer.

[0003] The existing dry-type transformers cannot intelligently control temperature, and the temperature control effect is poor, so a four-split dry-type transformer with intelligent temperature control function is needed to solve the above problems
