Intelligent electric field exceptional safety alarming device

The invention relates to an intelligent electric field exceptional safety alarming device which is capable of warning inspection staff to evacuate timely after an electric field changes, and the intelligent electric field exceptional safety alarming device is mainly applied to electric field early warning of key positions and an inspection channel of an electrical power system transformer substation. According to the structure, a power supply device provides power for other parts through a voltage stabilization device; an electromagnetic sensor set sends electromagnetic field intensity signals in a read space to a signal amplifying device, and the signal amplifying device converts received signals into current values capable of being recognized by a microprocessor and transmits the current values to the microprocessor; the microprocessor drives a buzzer or a voice device to give out alert sounds according to the induced electromotive force situation in the space. The intelligent electric field exceptional safety alarming device is arranged on key areas or an inspection route, can remind staff wanting to enter a failure area range to evade risks timely at any time, and is a safety early-warning protecting tool which can provide safety warning for running, inspection, testing and protection of electric power systems and maintenance staff simply, conveniently, effectively and intelligently, and eradicates or evades the occurrence of human casualty accidents.
