Maintenance Considerations For Dry-type Transformer Temperature Controller Failure

The temperature conditions of 35kv dry type transformer directly affect the thermal stress state of the internal insulation material and the long-term service capability of the winding in daily use. As a crucial component for monitoring and regulating the operating temperature of equipment 45 kva dry type transformer, the temperature controller plays a decisive role in the thermal behavior of the equipment, especially in scenarios involving continuous operation or load fluctuations.

When the thermostat fails to accurately reflect the temperature or issue commands, the real-time feedback of internal heat in the air cooled transformer dry type will be lost, and the system will be unable to respond to changes in the status of the external cooling device as set. When the thermal stress borne by the air insulated dry type winding insulation exceeds its design allowable range, the insulation performance degrades more rapidly, which may increase the probability of electrical faults.

If a fault occurs in the thermostat itself or the sensor signal is abnormal, the sensing circuit and control logic should be analyzed quickly. The thermostat typically collects winding heat data and outputs status prompts through temperature sensing elements such as PT100. Once the signal link is distorted, the signal link originally used for fan start/stop and alarm linkage will be interrupted, leading to thermal management deviations.
