Jinpan Technology has provided excitation transformers for China’s Fuqing Nuclear Power Plant.

Jinpan Technology’s dry-type excitation transformer products have provided support during the construction of Hualong No. 1 core components and the “going out” process.

The excitation system converts the three-phase power supply into the generator rotor DC power supply through the SCR to form the generator excitation magnetic field, and adjusts the trigger angle of the SCR through the excitation system to achieve the purpose of regulating the voltage and reactive power of the motor.

Fuqing’s unit 5 is the first in the world to be commisioned using a Hualing One reactor, and is operated by the China National Nuclear Corporation (CNNC).
