Transformers are devices that use electricity to convert mechanical energy into electrical energy. They are used in a wide variety of applications, such as power generation, telecommunications, and industrial automation. Transformers can be damaged by heat, which can fail and cause them to need thermal protection to prevent overheating through insulation and oil cooling of the transformer windings, which will not allow the transformer to exceed safe operating temperature and keep it cool.
Urgent reasons why transformers need thermal protection
Transformers need thermal protection to prevent damage from overheating. Overheating can cause the transformer’s insulation to heat up and melt, which can lead to shorts, fire, and even serious injury.
Transformers are designed to operate at high temperatures for a long period of time. They use a lot of power, so they need to be able to handle the heat.
Thermal protectors are designed to trip when the temperature of the transformer reaches a predetermined level, thereby interrupting the flow of electricity and preventing further heating.
Saftty’s Thermal Protection
Transformers require thermal protection to prevent transformer overload and fire. A Saftty thermal protector is a device placed in a transformer. When the temperature rises, due to the different expansion coefficients of the active layer and the passive layer, the bimetal sheet will bend and deform, and it will cut off the power supply of the transformer. When the temperature returns, the shape of the bimetal returns, creating a switch that closes and opens according to the temperature change. This will prevent the transformer from overheating and catching fire.
The thermal protector is an essential part of the overheating protection system that keeps the transformer coil from overheating. Welcome to contact Saftty for more information about thermal protection.
