Overview
This series of tapping switches are applied to the oil immersed transformer with frequency 50HZ、60Hz, rated voltage 10KV～35KV,rated current 63A～250A, Before changing the voltage, must cut of the power of the transformer, changed the turns of coil under off-circuit condition so as to realize the purpose of adjusting the voltage of the transformer; finally reach the purpose to adjust the secondary output voltage.
Changing the tapping position by such way: rotate the handle to drive the shaft, then the shaft drive the moving contactors. Thereby changing the transformer primary windingturns in order to change the transformer voltage and adjust the secondary voltage.
