BWDK-S201D Dry type transformer temperature monitor controller-INNO

BWDK-S201D is an intelligent temperature controller for flip type embedded small plastic shell dry-type transformers independently developed and produced by Fuzhou INNO. It is mainly used for temperature control and monitoring of dry-type transformers. Here is a detailed introduction:

技術仕様
環境温度: -20 ℃~+55 ℃.
Environmental humidity:<95% (25 ℃).
動作電圧: AC220V (+10%, -15%).
Working frequency: 50Hzまたは60Hz (±2Hz).
測定範囲: -30.0 ℃～ 240.0 ℃.
測定精度: ± 1% FS (temperature controller level 0.5, sensor level B).
解決: 0.1 ℃.
Fan output capacity: 9A/250VAC.
制御出力容量: 5A/250VAC; 5A/DC30V (抵抗性の).
Temperature controller power consumption: ≤ 8W.
特徴
Temperature display: It has three-phase circuit display and maximum value display functions, which can real-time understand the temperature situation of the three-phase winding of the transformer.
ファン制御: Supports automatic/manual start stop function of the fan, which can automatically control the operation of the fan according to the set temperature threshold, or manually force the fan to start.
アラーム機能: It has over temperature alarm and fault alarm functions. When one phase of the three-phase wire package exceeds the temperature or there is a sensor failure, the temperature controller will emit sound and light alarms and output corresponding switch signals.
Trip function: When the temperature reaches the set over temperature trip value, the temperature controller will output a trip signal to cut off the power supply of the transformer to protect it.
Other functions: It also has a “black box” 関数, which can record the temperature of the three winding wire packages before the power outage and the working status of the machine; The timed excitation function of the fan can avoid corrosion, blockage, and damage caused by long-term failure to start the fan; Simulation testing function, convenient for users to debug and test; Digital compensation function, which can calibrate temperature measurement; The cabinet door opening alarm function can prevent unauthorized personnel from operating.
