Gas protection is a kind of protection that directly trips the protected transformer when an internal short circuit (including a turn-to-turn short circuit) occurs in the dry type transformer, but the short circuit current fails to reach the set value of current protection. It belongs to the main protection of baoding dry type transformer. Transformer according to the action pressure of gas relay is divided into two situations, heavy gas action in tripping, light gas action in tripping and also action in signal.

 

2. Temperature protection

 

That is, the temperature of the winding is measured by the temperature controller, and the over-temperature alarm and over-temperature trip signals are sent out according to the prior setting. The baoding dry type transformer is generally equipped with two levels of temperature protection: low-temperature alarm and high-temperature trip. The specific temperature value can be set according to the instructions of the transformer manufacturer.

 

3. Indoor protection of dry type transformer

We need to prevent small animals such as rats, snakes, etc., from entering the transformer, which would normally cause a short circuit, or even a higher risk. Therefore, we can use the IP20 protective enclosure for protection.

 

4. Outdoor protection for dry type transformer

 

Mainly to prevent the rainwater and so on from entering. In the case of the protective case, we also need to adjust the Angle of the transformer to prevent the water droplets from entering. But now there is a professional exterior enclosure. In the concrete protection work, we should judge according to the environment, and should avoid the bad environment as far as possible, so as not to reduce the transformer performance.
