PROTECTIVE DEVICE FOR PREVENTING THE OVERLOAD OF CAPACITORS BY HIGH-FREQUENCY VOLTAGES

摘要

The invention relates to a protective device for capacitors (4 to 10) which are subjected to high-frequency voltages that are higher in relation to those under normal operating conditions, in particular, in a voltage range which lies significantly above the nominal voltage, as a result of a malfunction. The protective device functions in such a way that the current which is applied as a result of the voltage at the capacitors (4 to 10) is limited by a thermistor (11, 12).
