(4) the temperature control and temperature display device is set in an obvious position for easy observation.

(5) indoor lighting arrangement conforms to relevant regulations.

(6) the door of the room is made of non-combustible or non-combustible materials, and the door is opened outward with equipment name and safety warning sign on the door. The safety facilities such as protective screen door and railings are perfect.

Notes for dry type transformer

Temperature control system of baoding dry type transformer

1. The safe operation and service life of baoding dry transformer largely depends on the safety and reliability of transformer winding insulation. The insulation failure caused by the temperature of windings exceeding the insulation tolerance is one of the main reasons that the transformer cannot work normally. Therefore, it is very important to monitor the operation temperature of baoding dry type transformer and its alarm control.

2. Protection mode of dry type transformer

According to the use environment and protection requirements, baoding dry type transformer can choose different shell. Usually, IP23 protective enclosure is used to prevent the entry of solid foreign bodies larger than 12mm in diameter and small animals such as mice, snakes, cats and birds, causing malignant faults such as short circuit and power failure, providing a safety barrier for the live part. If the transformer must be installed outdoor, can select IP23 protective shell, apart from the above IP20 protection function, can prevent and more vertical line into water droplets into the within 60 ° Angle. However, the IP23 enclosure will reduce the cooling capacity of the transformer.

3. Cooling method of dry type transformer

Baoding dry transformer is divided into natural air cooling (AN) and forced air cooling (AF). During natural air cooling, the transformer can run continuously for a long time under rated capacity. When forced air cooling, output capacity of transformer can be increased by 50%. Suitable for intermittent overloading operation or emergency overloading operation; Due to the large increase of load loss and impedance voltage during overloading, it should not be in the state of non-economic operation.

4. Overload capacity of dry type transformer

The overload capacity of baoding dry type transformer is related to ambient temperature, load before overload (initial load), insulation heat dissipation of transformer and heating time constant.
