Details

This series of tap changers is suitable for oil-immersed power transformers with a frequency of 50Hz, a rated voltage of 10KV to 35KV, and a rated current of 63A to 250A. When the voltage needs to be adjusted, the transformer must be disconnected from the network. Make the transformer change the number of turns of the primary coil of the transformer under the condition of non-excitation, so as to realize the purpose of adjusting the voltage of the transformer. To achieve the purpose of adjusting the secondary output voltage
