Abstract
An apparatus (100) for damping vibrations in electrical lines (10) through which modulated currents flow has at least one sound or vibration sensor (102) oriented towards the line (10) or attached to the line, at least one actuator (104) connected to the line, and a control circuit (200) which is supplied, via respective signal lines (108), with signals generated by the at least one sound or vibration sensor (102) that represent sound or vibrations. The control circuit controls the at least one actuator (104) via respective control lines (110) such that this actuator counteracts the vibration of the line (10).
Claims13
An apparatus for damping mechanical vibrations in electrical lines through which modulated currents flow, said apparatus comprising:
- at least one sound or vibration sensor oriented towards the line or attached to the line, wherein the at least one sound and vibration sensor comprises an optical microphone,
- at least one actuator connected to the line, and
- a control circuit which is supplied, via respective signal lines, with signals generated by the at least one sound or vibration sensor that represent sound or vibrations, and which controls the at least one actuator via respective control lines such that this actuator counteracts the vibration of the line, wherein the at least one sound or vibration sensor allows spatial resolution of the vibration amplitude along at least part of the line, and wherein the control circuit is configured to control the at least one actuator such that a maximum vibration amplitude is reduced.
