Dry-type transformers are being developed in an intelligent direction by State Grid Co., Ltd. and China Southern Power Grid Co., Ltd. in recent years Combining electronic, communication, computer and network technology with power equipment, monitoring, protecting, controlling, metering, and managing the power grid under normal and accident conditions, data transmission, remote monitoring, equipment predictive maintenance, etc.

The Isolation Transformers Functions is prevent electric shock accidents by isolating the two-phase electricity! We must first understand the power supply system in my country. The power supply system in my country uses a three-phase four-wire system and the neutral wire is grounded.

1.The dry-type transformer should be checked for temperature:
2.Check the oil level:
3.Listen to the sound:
4.On the top cover of a dry-type transformer, check the insulation:
5.Ensure that the bolted joints leading out of the busbar are not overheated:
6. … …

There are one or more coils on a winding. A transformer winding consists of bundles of copper coils, each with a different number of turns. It depends primarily on the input and output power supplies, otherwise it depends on the voltage range. The transformer winding diagram is as follows:

Dry-type transformer is an important piece of electrical equipment and a very important electrical appliance. The structure and main functions of the dry-type transformer are being continuously improved , so as to meet the needs of everyone. Improved efficiency, enhanced functionality, and improved structure are all integral parts of the dry-type transformer.

Nine basic classifications for transformers are classified by structure, cooling method, winding method, application, and core type,Voltage regulation method, neutral point insulation level, conductor materials and installation methods.
