Do You Know The Advantage Of Isolating Transformers？

Isolation transformer is a kind of transformer with air as the cooling medium. A transformer with electrical isolation between the input winding and the output winding. The isolation transformer is used to avoid accidentally touching the live body at the same time. The isolation transformer is used to isolate the current of the primary secondary winding coil. Incoming reactor, also known as commutator reactor, can limit the current shock caused by voltage mutation and operating overvoltage of the power grid, effectively protect the terminal electrical equipment, and inhibit radio interference, and protect and improve its power factor. The three-phase reactor is used in series with the inlet and outlet terminals of the frequency converter, as the inlet and outlet reactors of the frequency converter, which can reduce the harmonics generated when the frequency converter is working. Different from oil-immersed transformers, it mainly uses natural air cooling and forced air cooling. Natural cold air is mainly used for transformers with small capacity and long-term operation, and forced air cooling is mainly used for transformers with large capacity and high temperature requirements. In addition, an appropriate temperature rise is allowed in operation, which is of great significance to improve the safety and stability of transformer applications in power systems. Today, we’re going to talk about the advantages of isolation transformers. Let’s see.

(1) Isolation transformer technology can effectively avoid the risk of fire and explosion of transformer oil due to failures in economic operation. Because the insulating structural materials of the social isolation transformer are refractory materials, even if some failures of the transformer in the operation of the system cause a fire or an external fire source, it will not make the fire situation continue to expand.

2. The isolation transformer does not have the same oil leakage problem as the oil-immersed transformer, and there is no problem of aging transformer oil.

3, isolation transformer is generally indoor equipment, for special requirements of the place can also be made outdoor, it can be installed in the same room with the switch cabinet, reduce the installation area.

4. Because the isolation transformer is oil-free, there are fewer accessories, no oil storage tank, no safety airway, valves and other parts, and no sealing problems.

5, isolation and transformer insulation technology performance is good, strong reliability. The allowable temperature rise of the isolation working transformer, compared with the traditional oil-immersed transformer, has greatly improved the moisture-proof system function of the social isolation transformer.

6. Isolation transformer is more and more used in various power projects because of its good safety performance, low energy consumption, moisture-proof, simple operation and easy maintenance.

These are the six advantages of isolation transformers. It can not only avoid the danger of transformer oil fire and explosion caused by fault in operation, but also has good insulation performance, strong reliability, good safety performance, low energy consumption, moisture-proof, simple operation and easy maintenance. Widely used in urban buildings, rail transit facilities and other public places.
