| Zusammenfassung: | The invention provides a current transformer expander volume change online monitoring and diagnosing method. The method comprises the steps that the distance between the top of a current transformer expander and a distance measuring sensor is collected in real time; the distance between the top of the current transformer expander and the distance measuring sensor is a diagnosis distance; online monitoring and state diagnosis are carried out on the current transformer expander according to the diagnosis distance; and when the diagnosis distance exceeds a preset diagnosis distance threshold, analarm signal is sent. In addition, the invention further provides a distance measuring sensor, a current transformer expander volume change online monitoring and diagnosing device and a storage medium. Through the technical scheme provided by the invention, 24-hour online uninterrupted monitoring of a current transformer is realized, the running and fault states of the current transformer equipment can be evaluated, accid |
