Transformer thermal protectors are specially designed devices for monitoring and controlling the temperature of transformers. During operation, transformers generate heat, and if the temperature exceeds safety thresholds, it can lead to the degradation of insulating materials, coil damage, or even fires, posing serious problems. Therefore, thermal protectors play a crucial role in ensuring the safe operation of transformers. Here is how transformer thermal protectors work:

Temperature Sensing:

Thermal protectors typically include one or more temperature sensors, such as thermistors (NTC or PTC) or temperature switches. These sensors are capable of detecting changes in the temperature of the transformer.

Temperature Monitoring:

The sensors continuously monitor the temperature of the transformer. When the temperature reaches a preset safety threshold, the sensor sends a signal.

Signal Processing:

The control circuitry within the thermal protector receives signals from the sensors and processes them according to preset temperature parameters.

Action Execution:

If the temperature exceeds the safety limit, the control circuit triggers a protective mechanism. This may include cutting off the power supply, issuing an alarm, or activating a cooling system, among other actions.

Automatic or Manual Reset:

Some thermal protectors are designed to automatically reset once the temperature drops to a safe range. Others require manual reset to ensure that the issue is properly addressed.

Remote Monitoring and Control:

In modern transformer systems, thermal protectors may be connected to remote monitoring systems, allowing operators to monitor the temperature of the transformer in real-time and execute control commands remotely when necessary.

Fault Recording:

Some advanced thermal protectors also have fault recording capabilities, which can log the occurrence time, duration, and temperature values of temperature异常 events for later analysis and maintenance.
