Dry-type transformers temperature controller BWD-3K130B

Changsha Longwell Electric Co., Ltd. ■ BWD-3K-130D dry-type transformers temperature controller Supply Phone: 0731-84280488 BWD-3K-130D dry-type transformers thermostat quote Fax: 0731-23353178 ★ Overview: BWD-3K-130 Series Thermostat for air-cooled dry-type power transformers reliable operation and design of a new generation multifunction computer temperature controller. As a result of the most advanced German RISC single-chip computer and I2C combined with advanced storage and adjustment technology, designed according to JB / T7631 standard, so the thermostat has a simple structure, reliable operation, anti-interference ability characteristics. Meanwhile thermostat also has a "black box" function, you can record the temperature and state of the unit before the power cut three winding line package. Utilizing embedded in the dry-type power transformer three-phase winding line package III Pt100 platinum resistance to detect the temperature of dry type power transformer line package, and until the super automatic temperature control based on the cooling fan start and stop, over-temperature alarm High Temperature trip to ensure safe operation of dry-type power transformers. ★ performance indicators: 1.
