Overview

The CFZ-6Q6 transformer cooling fan (also known as transformer cooling fan or heat dissipation fan) is an important auxiliary equipment for forced oil circulation air cooling or strong wind cooling transformers. Its core function is to accelerate the heat dissipation of transformers and ensure that they operate at safe temperatures. $r$n。 Principle: Transformers generate a large amount of heat due to iron and copper losses during operation. The heat causes the transformer oil to heat up, and the oil circulates in the radiator (heat dissipation fins). The fan greatly improves the air convection speed by forcibly blowing air through the radiator, thereby quickly removing heat from the radiator, which is equivalent to installing a "forced cooling system" for the transformer

CFZ-6Q6Transformer cooling fanTechnical Analysis+

The start stop control of the fan is directly related to the efficiency, lifespan, and energy consumption of the transformer. Common control strategies include:

1. Temperature control and oil temperature control: Install a temperature sensor (usually a PT100 platinum resistor) on the transformer oil tank. When the top oil temperature reaches the set value (e.g. 55C), start the fan; When reaching the second level set value (e.g. 65C), start the second group/all fans; When the oil temperature drops to the set value for air stop (e.g. 50C), the fan will automatically stop. Winding temperature control: Simulate hot spot temperature through current transformers, with control logic similar to oil temperature but better reflecting load conditions. 2. Load current control: Start and stop the fan according to the magnitude of the transformer load current. Can be used in parallel with temperature control as a backup or composite judgment condition.

3. Manual control: Use buttons on the control cabinet to force start and stop,
