BWDK series temperature monitor for power transformers

The BWDK series temperature monitor for power transformers is an embedded dry-type transformer temperature control box. With three platinum resistance thermometers as sensors, it can monitor and display the temperatures of the three-phase windings and core in real time. It outputs control contacts for functions like fan operation and alarms, and transmits temperature data and operational status to the backend monitoring system via RS485 communication and 4–20 mA analog current signals. The monitoring system has audio-visual alarm functions and is crucial for dry-type transformer protection. Default temperature settings are: fan stops at 80°C, starts at 100°C, alarms at 130°C, and trips at 150°C. #transformermonitoring #temperaturesensor #temperaturecontroller
