The utility model discloses a high-voltage alarm device comprising a housing, a sensor, a signal processor, a threshold value controller, an alarm, and a power supply, wherein the sensor, the signal processor, the threshold value controller, the alarm and the power supply are disposed in the housing. The sensor is used for acquiring an electromagnetic field signal. The signal processor is used for processing the electromagnetic field signal acquired by the sensor. The threshold value controller is used for switching a preset electromagnetic field signal threshold value. The alarm is used for giving alarm information. The power supply is used for supplying power to each electric unit. The sensor, the signal processor, the threshold value controller, and the alarm are successively connected. The alarm gives alarm information when the electromagnetic field signal acquired by the sensor exceeds the electromagnetic field signal threshold value preset by the signal processor. When the distance between a worker and a high-voltage electric apparatus is smaller than that prescribed by a safety requirement, the high-voltage alarm device may automatically give alarm indication, is easy to operate and convenient to use, and guarantees the personal safety of the worker.
