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.

The main so Popular of dry-type transformers are low losses, low noise, excellent fire resistance, no flammable resins, non-toxic gases, nonflammable, self-extinguishing, low pollution, good insulation, and no maintenance. No partial discharge, strong lightning shock resistance, high mechanical strength, high temperature resistance, short circuit resistance, moisture resistance, and can work under high humidity conditions. No partial discharge, strong lightning shock resistance, high mechanical strength, high temperature resistance, short circuit resistance, moisture resistance, and can work under high humidity conditions.

We discuss common transformer faults and solutions in this article. The faults listed in the article are commonly faults in transformers, and some can only appear in large-capacity power transformers. Repair methods are limited to small faults and only available in professional repair factory/team. It is important to identify the situation based on the actual circumstances.

Due to the fact that dry-type transformers’ energy-saving effect and efficiency are constantly improving, it can be said that the energy-saving effect and energy-saving advantages of dry-type transformers are greatly improved. Furthermore, due to the large amount of energy generated, the economic development is more powerful.

Transformers used in medical applications must meet the following requirements:
1.The safety and compliance standards are different. The medical isolation transformer safety and compliance standards higher national industry standards (iec61558-1-2) and international standards (UL 60601-1:1988)
2.Lower leakage current
3.The creepage distance and air gap are smaller
4.Lower temperature rise
5.Hi Pot standard (generally above 4000V)
6.Insulation grade (generally grade B above 130 ℃)
7.Bottom lead wire design
8.Electrostatic shielding is required between primary and Second
9.Built in recoverable thermal protector device etc.
