Product details
Series of electronic temperature controller for dry-type transformer
Bwd-k electronic temperature controller for transformer is an intelligent instrument composed of microprocessor. The platinum resistance of Pt100 is used as the temperature sensor. The platinum resistance is put into the transformer winding respectively. When the temperature of transformer changes, the platinum resistance changes synchronously with the temperature. The temperature controller can control the set temperature value. It can start and stop the cooling fan, send out fault alarm, over temperature alarm, control over temperature trip, etc. to protect the transformer.
This instrument is specially designed and manufactured according to JB / T 7631-2005 "electronic temperature controller for transformer" which is the executive standard of mechanical industry.
