Transformer cooling system || Hindi

Hello friends,

In today's video we will learn about cooling system of transformer. All rhe types of cooling system are explained in detail.

The cooling system of a transformer plays a critical role in maintaining the optimal operating temperature, ensuring efficient performance and longevity. There are primarily two types of cooling methods used in transformers:

Oil Cooling:

Oil as a Coolant: Many transformers use oil as a cooling medium. The oil circulates through the transformer, absorbing heat generated during operation.
Cooling Fins: Transformers equipped with oil cooling often have cooling fins attached to the tank. These fins increase the surface area for better heat dissipation.
Radiators: Larger transformers may have external radiators through which oil circulates, facilitating enhanced cooling through convective heat transfer.

Air Cooling:

Natural Convection: Smaller transformers or those with lower heat dissipation requirements may rely on natural convection for cooling. The surrounding air naturally cools the transformer as it rises due to temperature differences.
Forced Air: In larger transformers or those with higher heat loads, fans or blowers are employed to force air over the cooling surfaces, improving heat exchange and cooling efficiency.

Combination Cooling:

Hybrid Systems: Some transformers use a combination of oil and air cooling. This hybrid approach leverages the benefits of both methods to optimize cooling efficiency.
On-Load Tap Changers (OLTC): Transformers with OLTC may have additional cooling systems to manage the heat generated during tap changing operations.
Cooling Control:

Thermostatic Controls: Temperature sensors and thermostatic controls are often integrated into the transformer to monitor and regulate the oil or winding temperature.
Fans and Pumps Control: In forced air or oil cooling systems, fans and pumps may be controlled based on temperature conditions to ensure efficient cooling.
Cooling Equipment Location:

Internal vs. External Cooling Equipment: Some transformers have the cooling equipment integrated internally, while others may have external radiators, fans, or pumps.
The effectiveness of a transformer's cooling system is crucial for preventing overheating, which can lead to reduced efficiency, insulation degradation, and ultimately transformer failure. Regular monitoring and maintenance of the cooling system are essential to ensure reliable and continuous transformer operation.
