摘要： A method and a device are described for detecting a fault current across a piezoelectric actuator (5) of an injector or its high voltage supply lead (6, 6a). Because the fault current upon contact with a person, for example, is relatively small compared to the useful current that charges or discharges the actuator, direct measurement of the current is not reliable. Therefore, it is suggested that, during the injection or in an injection pause, when the piezoelectric actuator (5) is charged, the voltage variation or a change in voltage (dU) be measured and the difference be compared to a predefined threshold value (S). When the threshold value (S) is exceeded, a fault message is produced, the voltage source is shut off, and/or the piezoelectric actuator (5) is discharged. The measured fault can be weighted using a counting algorithm. The method thus provides maximum protection upon contact, in particular for service personnel.
摘要翻译：描述了用于检测喷射器或其高压电源引线（6,6a）的压电致动器（5）上的故障电流的方法和装置。因为例如与人接触的故障电流相对于对致动器进行充电或放电的有用电流相对较小，直接测量电流是不可靠的。因此，建议在注入或注入暂停期间，当压电致动器（5）充电时，测量电压变化或电压变化（dU），并将该差异与预定阈值（ S）。当超过阈值（S）时，产生故障消息，关闭电压源，和/或压电致动器（5）放电。测量故障可以使用计数算法加权。因此，该方法在接触时提供最大的保护，特别是对于维修人员。
