Abstract
The utility model provides a kind of high voltage cable fault location device, it is related to power system fault diagnosis and protection technical field, the device includes host computer and rogowski coil, host computer includes mainboard, and mainboard includes main MCU, deputy MCU and FLASH memory;Rogowski coil is used to collect current signal in high voltage cable;Mainboard is connected with rogowski coil, for receiving current signal, and when current signal meets preset condition, trigger signal is generated;Deputy MCU is used to temporarily store current signal, and after receiving trigger signal, current signal is transferred to FLASH memory;Main MCU connects deputy MCU and FLASH memory. Current signal is temporarily stored by deputy MCU and under the control of trigger signal, current signal is transferred to FLASH memory, main MCU controls the transfer and reading of current signal, realizes the efficient collection and storage of high voltage cable fault transient traveling wave signal, improves the real-time and integrity of data acquisition, avoids data loss, thereby improves the accuracy and reliability of fault location.
