The temperature controller for dry-type transformers is an intelligent controller designed specifically for the safe operation of dry-type transformers. The temperature controller adopts microcontroller technology and uses the platinum thermistor embedded in the dry-type transformer winding to detect and display the temperature rise of the transformer winding. It can automatically start and stop the cooling fan to force air cooling of the winding, avoiding or reducing faults caused by high temperature in the transformer. It can also control the output of over temperature alarm and over temperature trip to ensure that the transformer operates in a safe state, thereby extending the working life of the transformer.
Product Selection:
| model | function |
| BWDK-Q201D |
|
| BWDK-Q201E | 4-20mA output for integration with SCADA systems |
| BWDK-Q201F | RS485 or RS232 serial communication function. |
| BWDK-Q201G | An additional sensor is added to measure the ambient temperature |
| BWDK-Q201I | An additional sensor is added to measure the temperature of silicon steel sheet |
| BWDK-Q201C | Add thermistor PTC150 or PTC130 for interlocking control |
Remarks:
1. For example: BWDK-Q201F dry-type transformer temperature controller, BWDK represents the national standard model of the temperature controller, Q represents the embedded iron shell temperature controller, and F is the code for communication function;
2. E, F, G, I, and C are all function codes, which can be combined. The following examples are provided to illustrate:
Temperature controller model: BWDK-Q201FG, indicating that it is an embedded iron shell temperature controller. Its functions include: conventional function, communication function (F), and an additional room environment temperature measurement and control function (G).
If there are already two functions, E and F, and only one of the G and I functions can be selected as an additional function, and there are at most three simultaneously existing function codes. For example, the temperature controller models are BWDK-Q201EFG and BWDK-Q201EFI.
3. If there are other special technical or functional requirements, such as Ethernet communication, Profibus communication, multi-channel temperature measurement, filo optic e mafana ʻo e ʻea, mo e ala meʻa pehē., you can contact us.
