A power transformer is a stationary electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. Transformer is a static electrical equipment used to transform AC voltage and current to transmit AC power.
Dry-type transformers are transformers whose cores and windings are not immersed in insulating oil. Because dry-type transformers have the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise, they are often used in places with high performance requirements such as fire protection and explosion protection.
The company is a comprehensive electrical equipment manufacturing enterprise integrating R & D and production of electrical equipment such as distribution transformers, intelligent switch cabinets and box-type substations.
The safe operation and service life of dry-type transformers largely depend on the safety and reliability of the transformer winding insulation. It is one of the main reasons that the transformer can not work normally because the winding temperature exceeds the insulation withstand temperature and the insulation is damaged. Therefore, the monitoring of the operating temperature of the transformer and its alarm control are very important.
