​Temperature Controller For Dry Type Transformer using three Pt100 platinum thermal resistors embedded in the three-phase winding package of the dry power transformer to detect the temperature rise of the dry power transformer line package, and automatically control the start and stop of the cooling fan according to the temperature rise, and the over temperature alarm until the super High temperature tripping to ensure safe operation of dry power transformers. Due to the use of the most advanced German RISC single-chip computer combined with advanced IC storage and adjustment technology, designed according to JB/T7631 standard, the thermostat has the characteristics of simple structure, reliable operation and strong anti-interference ability. At the same time, the thermostat also has a "black box" function, which can record the temperature of the three winding wire packs before the power failure and the working state of the machine.

Introduction Of Function:

1. Detect and patrol the three-phase wire package winding temperature or only the one-phase winding temperature of the highest temperature in the three-phase wire package winding. Each phase is displayed for about 8 seconds during the tour display.

2. Fault sound and light alarm: When the sensor is faulty, the corresponding A, B, C phase indicator lights, and the fan starts, the machine beeps and the alarm contact is turned on. The display shows X-HO or X-LO, where X indicates the fault phase.

3. Fan start and stop function: When one phase of the three-phase coil winding reaches the set fan starting temperature value, the fan starts automatically, and the fan indicator lights when the fan starts. The fan automatically turns off when no phase temperature in the three-phase wire envelope group is greater than the set fan shutdown temperature value.

4. Over-temperature alarm function: When one phase of the three-phase wire envelope group reaches the set over-temperature alarm temperature, the thermostat emits an audible and optical alarm, and the alarm output terminal is connected (normally between the two terminals is Disconnected, the alarm will be turned on.) Provide a switch signal to give an audible and visual alarm to the remote control cabinet.

5. Automatic trip function: When one of the three sets of wire package windings reaches the set trip temperature value, the temperature controller turns on the trip output terminal (normally, the two terminals are disconnected, and the two terminal ports are tripped. It will be turned on) to provide a switch signal to the remote control cabinet to activate the trip circuit. (To prevent triggering trips due to accidental factors, there is a special 5S delay).

6, manual start to turn off the fan function: press the fan button, the fan starts, then press the fan button, the fan is off. If the manual fan starts without manually turning off the fan, the fan will automatically shut down after about 15 minutes of startup.

7. Fan timing detection function: In order to avoid the rust and blockage damage caused by the fan not starting for a long time, the fan timing detection function is specially set, the timing start time can be set, the range is 0-199 hours, and the temperature controller is set to the set value. Automatically detect the start fan for about 2 minutes, and cancel the function when you enter 000.

8. Self-test of control function: It can simulate the input of temperature signal and make the temperature controller control accordingly.

9. “Black Box” function: It can record the temperature of the three-phase wire package winding at the time when the temperature controller is powered off, and the working state of the machine.

10. All temperature settings can be set directly through the touch buttons on the panel. In order to prevent the setting of the idle person, the temperature controller has a password, and only the password input can be set correctly, otherwise it can only be viewed and cannot be set. Set the temperature range as shown in the following table:
