AN ORGANIC COMBINED INSULATED DRY ELECTRONIC TRANSFORMER FOR OUTPUTTING THE OPTICAL SIGNALS

摘要

An organic combined insulated dry electronic transformer for outputting an optical signal, in which an organic insulated capacitor voltage-divider insulator is used as the main insulator to bear all the whole high voltage. A coreless coil is wound around the outside of the tap of capacitance plate in the capacitor voltage-divider insulator to measure current; or a low voltage signal is taken from the capacitance plate adjacent to the tap of capacitance plate in the capacitor voltage-divider insulator to measure voltage; then the received current signal or the voltage signal is transformed into an optical signal by a converter that converts an electric signal into an optical signal and then outputted. The coreless coil as a current sensor has ground potential and the capacitor as a voltage sensor has low potential.
