| BWR-04 transformer winding thermometer is an intelligent temperature monitoring and control device designed for power transformers. It integrates advanced temperature measurement technology, multiple control functions and intelligent alarm system, aiming to ensure the safe operation of transformers under various working conditions and effectively prevent failures caused by overheating. BWR-04 series winding thermostat adopts the principle of additional temperature rise, simulating the temperature after the superposition of the top oil temperature of the transformer and the average temperature rise of the winding to the oil. Its working principle is to take out the current proportional to the load through the current transformer, adjust it through the power matcher, and input it into the electric heating element embedded in the elastic element of the thermostat. The heat generated by the electric heating element causes an additional displacement of the elastic element, thereby generating an additional temperature rise. |
| Technical Specification: Normal working conditions: -40ºC~+55ºC Measuring range: 0~150ºC Accuracy level: 2.0 Contact action error: ±4ºC Contact capacity: AC220V, 5A or DC27V, 10A. Temperature package size: Φ14×150 or customized Power supply matcher: Determined according to transformer current transformer |
| Product features: Accurate measurement, timely warning of abnormal temperature, and effective prevention of transformer overheating failure. Equipped with four sets of control switches, which can be used for signal alarm, cooler control and accident tripping according to actual needs. Intelligent alarm to ensure timely detection and handling of abnormal temperature problems. Equipped with a secondary remote digital display instrument with a voltage-stabilized power supply, it can monitor temperature from a distance. |
