Introduction: BWR-04J (TH) transformer winding thermometer is a transformer-specific instrument. The instrument is designed with the principle of additional temperature rise, the product has a small size, full function, easy installation, simple operation and so on. And can output DC (4-20) mA standard current signal for the computer system and the use of secondary instruments to achieve unattended power station management. BWR-04J (TH) transformer winding thermometer, mainly by the elastic components, sensing catheter, temperature components, electric components, integrated converter and digital instrument composition. The temperature of the winding thermometer is the temperature of the transformer oil when the transformer load is zero, when the transformer is loaded with the load, the transformer current through the transformer The transformer is taken out of the current proportional to the load, the converter is adjusted through the corrugated tube in the heating element; electric components generated by the heat, so that the displacement of the elastic components increased. Therefore, after the load on the transformer belt, the displacement of the elastic element is determined by both the top oil temperature of the transformer and the load current of the transformer. The temperature indicated by the transformer winding thermometer is the sum of the transformer oil temperature and the temperature rise of the coil to the oil. The temperature of the hottest part of the transformer coil. Technical Parameters: Output signal: DC (4-20) mA Standard current signal Working conditions: ambient temperature (-40 ~ +55) ℃, relative humidity ≤ 95%. Measuring range: (0 ~ 150) ℃. Accuracy: 2.0 (maximum error allowed at the test point is ± 3 ° C). Switch performance: four adjustable switch, each set of switches can be set within the full range. Switch action error: ± 2 ℃. Switch switching difference: 6 ± 2 ℃. Switch rated power: AC250V / 5A. Temperature package size: (Ф14 × 105) mm, the installation of the thread (M27 × 2) mm Capillary length: 5m. Protection class: GB4208-84 IP55.
