Dry-type transformers will generate a lot of heat during operation. Therefore, you must pay attention to the cooling of the dry-type transformer during use. Dry-type transformer cooling fans are commonly used cooling equipment for dry-type transformers.
Dry-type transformer cooling fan is a commonly used cooling fan, mainly used in electronic equipment, distribution cabinets, high and low voltage switch cabinets and other products. There are some usage conditions that users need to master when using dry-type transformer cooling fans. Today, we will introduce the usage conditions, installation and maintenance of dry-type transformer cooling fans in detail.
Conditions for use of dry-type transformer cooling fans:
1. The ambient temperature should be 75oC≥-40oC.
2. The industrial gas passing through the cooling fan is not allowed to contain strong acids, strong alkali and various solutions.
3. Sand, dust and other debris are not allowed to fall into the fan to avoid burning the fan and breaking the fan blades.
Installation and maintenance of dry-type transformer cooling fans:
1. Before installation, you should first check whether there is any 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 whether the parts and screws are loose; whether the blades and the air duct collide or shift. If they collide or shift, they should be adjusted before installation.
3. The cooling fan should be tested after installation, and the cooling fan should be used online after the fan operates normally.
4. When the fan is placed for a long time and reused, the fan should be inspected and tested for trial operation. If there are no abnormal phenomena, it can be used online.
5. After the fan is installed, the wiring joints should be sealed to prevent leakage of the wiring joints, causing a short circuit and burning the motor.
