Dry-variable cross-flow cooling fan for Dry-type transformer

Transformer Cooling fan service conditions:
1. The ambient temperature should be 75 ° C ≥ -40 ° C.
2. Industrial gases passing through the cooling fan are not allowed to have strong acids, alkalis, or various solutions.
3. It is not allowed for debris such as sand and dust to fall into the fan, in order to avoid fan burning and blade breakage.

Installation and maintenance of Cross Flow cooling fans:
1. Before installation, it is necessary to first check whether there is damage or deformation caused by packaging and transportation. If there is any damage or deformation, it should be repaired before installation and use.
2. Then check if all parts and screws are loose; Is there any collision or displacement between the blades and the air duct? If there is any collision or displacement, adjustments should be made before installation.
3. After the installation of the cooling fan, a trial run should be carried out, and it can only be used online after the fan runs normally.
4. When the fan is placed and reused for a long time, it should be inspected and tested for operation. If there are no abnormal phenomena, it can only be used online.
5. After the installation of the fan, the wiring should be sealed to prevent leakage of the wiring from causing short circuits and burning the motor.

When this series of cooling fans are used in dry-type transformers, the fans are placed on both sides of the lower part of the transformer coil, and the cold air is blown directly into the high and low voltage cooling ducts of the coils of the transformer, and the heat dissipation effect is obvious, which can ensure the normal operation of the transformer and extend its service life. (Fan starting, stopping and transformer overtemperature alarm, overtemperature tripping and other functions are provided by temperature control devices).
