Abstract

The invention relates to an electrified length measurement simulation system for a high voltage cable. The system comprises a high voltage test cable, a first coupler, a second coupler, a third coupler, a pulse injection module, a signal measuring module and a synchronizing signal detection module. The signal measuring module generates trigger pulse transmitted to the pulse injection module which receives the trigger pulse and outputs coded pulse to the synchronizing signal detection module to be received. The synchronizing signal detection module records the waveforms of the trigger pulse and the coded pulse on a time shaft and measures the electrified length of the high voltage test cable according to time and pulse spreading speed corresponding to the waveforms. In addition, the invention further provides a local discharge detection and positioning simulation system for the high voltage cable. According to the invention, the measuring process of the electrified length of the high voltage cable and the local discharge detection and positioning process are simulated with low simulation cost and high efficiency, so that the invention can be applied to various experimental platforms and training systems and is suitable for common popularization and use.
