The national electric power investment Co.

Ltd. is located in the western part of Jiangxi province and is a domestic large-scale circulating fluidized bed demonstration base. In order to improve the stability and reliability of large-scale transformer operation

the measurement technology of the large-scale transformer temperature monitoring system of our 330 MW unit was improved

and the mechanical contact temperature controller was replaced with a digital intelligent temperature controller. The resistance temperature sensing element replaces the thermal expansion and contraction type temperature sensing element

which makes the transformer temperature monitoring system more accurate

stable and reliable

and is more suitable for the needs of safe production and long-cycle production.
