Explosion-proof intelligent fault indicator

The invention discloses an explosion-proof intelligent fault indicator comprising a fault collector, a collection unit and a main station. The fault collector comprises a current acquiring module, a backup power source, a power conversion module, a battery voltage sampling and control module, an electric field sampling module, an RF module, a power control, a programming interface, a protector, adriver, a low-power controller, an indicator board, a reset control module and a driving circuit. The collection unit includes a solar power supply, a backup power module, an RF communication module,a GPRS communication module, an encryption module, an external clock unit, a backup power activation control module and an external storage function module. The explosion-proof intelligent fault indicator is able to accurately determine an interphase short-circuit fault, a ground fault, a transient fault and a permanent fault in distribution line faults, accurately uploads a fault record to a distribution network main stat
