The core function of the transformer temperature controller is to monitor the temperature in real time and linkage protection, preventing the equipment from being damaged due to overheating by accurately sensing the temperature changes in the key parts of the transformer, and at the same time, assisting in optimizing the operation efficiency. Specific functions can be developed from monitoring, control, protection, auxiliary management and other dimensions:
I. Core monitoring: real-time temperature dynamics
Multi-point temperature acquisition: through the temperature sensor (such as platinum resistance Pt100, fiber optic sensor, etc.) embedded in the transformer windings, core or tank, real-time acquisition of temperature data in several key areas, some high-end products can simultaneously monitor the winding temperature, oil temperature, ambient temperature and so on.
Accurate display of data: visualize the current temperature in the form of numbers, pointers or LCD screen, some intelligent controllers can also display the temperature curve, historical maximum value, etc., which is convenient for operation and maintenance personnel to quickly determine the status of the equipment.
Second, intelligent control: automatic adjustment of cooling equipment
According to the preset temperature threshold, automatically control the start and stop of the cooling device (such as cooling fan, oil pump) to realize closed-loop regulation:

When the temperature reaches the start-up threshold (e.g. 60°C), the fan or oil pump is automatically turned on to enhance heat dissipation;
When the temperature drops to a stop threshold (e.g. 40°C), the cooling equipment is automatically turned off to reduce energy consumption.
Some products support multi-level control (e.g., low, medium and high speed fan graded start), adjusting the intensity of heat dissipation according to the temperature, taking into account the cooling effect and energy saving.
Three, multi-layer protection: to prevent equipment overheating damage
When the temperature exceeds the safety range, it triggers the multi-level protection mechanism to avoid the expansion of the fault:

Over-temperature alarm: When the temperature reaches the warning value (e.g. 80℃), the operation and maintenance personnel will be reminded to deal with it in time by means of acoustic and visual alarms and relay contact outputs.
Over-temperature trip: when the temperature reaches the dangerous value (such as 100℃), output trip signal, linkage disconnect the power supply of the transformer, forced to stop the operation, fundamentally prevent the winding from burning, insulation aging and other serious failures.
Failure self-test protection: If the sensor is disconnected, line failure or the controller itself is abnormal, it will trigger a failure alarm to avoid misjudgment or omission due to monitoring failure.
Fourth, auxiliary functions: enhance the operation and maintenance and management efficiency
Historical Data Record: Store the historical data of temperature change (such as the maximum temperature per hour, alarm time, etc.), and some products support uploading to the monitoring system through RS485 and other communication interfaces, which is convenient for remote query.
Manual/automatic switching: support manual start/stop cooling equipment to meet the needs of maintenance or special working conditions.
Anti-interference design: electromagnetic shielding, filtering and other technologies to resist strong electromagnetic interference during transformer operation, ensuring stable and reliable temperature measurement and control signals.
Summary: Temperature controllers are the "temperature control bodyguard" of the transformer
Transformer temperature controller through the "monitoring - judgment - action" closed-loop logic, not only real-time feedback equipment temperature status, but also automatically intervene in the cooling process, but also in the danger of mandatory protection, is to protect the transformer safe and efficient operation of the key equipment. The core value of its function lies in: controlling the temperature within the safe range, prolonging the life of the equipment and reducing the risk of failure.
