BWDK-S series of dry-type transformer temperature controller is an intelligent instrument equipped with a microprocessor.
It uses three platinum resistances as sensors to measure the temperature of three-phase windings of the dry-type transformer, and
start and stop the fan for temperature control according to preset temperature value. With various sound and light alarm functions,
the instrument is an important device for protecting the dry-type transformer.
BWDK-3207B干式变压器温控器符合JB/T7631-2005 标准。 The instrument complies with Standard JB/T7631-2005.
BWDK-3207B干式变压器温控器具有以下特点： The instrument has features as follows:
1. BWDK-3207B干式变压器温控器可以测量干式变压器三相绕组的温度，用LED 每隔4 秒循环显示三相温度值或定点显示三相温度最大值。
It is capable of measuring the temperature of three-phase windings of the dry-type transformer, displaying in turn three-phase
temperature values with a LED every 4 seconds or displaying the highest three-phase temperature periodically.
2. BWDK-3207B干式变压器温控器可以用按键输入4 种温度设定值。当测量温度超过各设定值时，分别控制风机启停、超温报警、超高温跳闸等。
温度设定值可以随时修改，断电后不会消失。
Four preset temperature values can be input by keystroke. When the measured temperature exceeds preset values, the
instrument will respectively control startup and stop of the fan, over-temperature alarm, ultra-high temperature trip, etc. The preset
temperature values can be modified at any time, and will remain after the instrument is switched-off.
