#$%^&*AU2018222964A120190328.pdf#####ABSTRACT There are provided a spark detecting apparatus for devices using electric sliding contact and a spark 5 detecting method for devices using electric sliding contact, in which in an electric machine having an electric sliding contact mechanism, a spark occurring in an electric sliding contact section is detected early and accurately, so as to enable the unexpected stop avoidance 10 and the static operation of the electric machine. A spark detecting apparatus for devices using electric sliding contact includes a static part, a sliding part becoming electrically conductive while making sliding contact with the static part, a frequency filter selectively passing a 15 voltage signal in a particular band, a volt meter electrically connected to the static part through the frequency filter, and a detecting apparatus for sliding condition determining the presence or absence of spark at the sliding interface between the static part and the 20 sliding part. When a voltage signal detected by the volt meter exceeds a predetermined threshold value, it is determined that a spark has occurred.1/10 FIG.
