TRANSFORMER ARRANGEMENT FOR SECONDARY DISTRIBUTION NETWORK VOLTAGE SUPPLY

摘要

Transformer arrangement (14) for secondary distribution network voltage supply, having: - a transformer (20) for converting a primary voltage in the form of a medium voltage in the range of from 1 kV to 50 kV into a seconary voltage which is lower than the primary voltage for sercondary distribution network supply; - an adjusting device (19) for mathching the ratio of the primary voltage and the secondary voltage; - a control device (18) for detecting the voltage on at least one of the phases and for controlling the adjusting device (19) on the basis of the detected voltage, wherein the control takes place in such a way that a discrepancy between voltage values occurring on the secondary distribution network and a predeterminable setpoint voltage value for the secondary distribution network is reduced.
