Abstract

The invention relates to the technical field of equipment hot-line monitoring, and provides a low-voltage grounding far-end alarm device, which comprises a power supply, an alarm unit, a wireless communication unit, a voltage detection unit and a voltage acquisition unit capable of acquiring voltage on an electric equipment housing or a grounding body. The power supply and the voltage acquisitionunit are both connected with the voltage detection unit; and the voltage detection unit is connected with the alarm unit and the wireless communication unit. The device is simple in structure and convenient to use, can obtain and detect the voltage on the electric equipment housing or the grounding body in real time, judge whether the voltage exceeds a threshold value so as to give an alarm in time to alert personnel not to touch or get close, so that safety of the use personnel of the electric equipment is effectively ensured, and safety accidents are avoided; and a far-end maintainer is informed in time to handle the fault in time to ensure that the electric equipment is recovered to be used in time.

Description

technical field [0001] The invention relates to the technical field of point monitoring of equipment, and relates to a low-voltage grounding remote alarm device. Background technique [0002] In recent years, with the increase of household electrical equipment, the personal casualty accidents caused by electric leakage and zero line electrification are also increasing. The neutral line is the power circuit of single-phase 220v electrical equipment. Since the neutral line and the ground are connected under normal conditions, that is, the same potential, the neutral line is not charged under normal conditions. If the neutral wire is disconnected and is not connected to the ground, the breakpoint will be encountered when the current passes from the live wire through the load to the neutral wire. At this time, the live wire, load, and neutral wire are all charged, and all grounded equipment casings will be charged at this time. Since electricity is invisible and intangible, on...
