Abstract

The invention discloses a near-electricity-sensing group calling and early-warning device so that a problem that electric shock occurrence is caused because the operator does not notice that the distance to the high-voltage line is smaller than the safety distance in the prior art can be solved. After a high-voltage electricity induction module senses an induced voltage, digital filtering is carried out and a useful voltage is extracted; an MCU analysis carried out; when a carrier enters a dangerous distance range, voice alarming is carried out and the alarming information is sent to other near-electricity-sensing calling and early-warning device by a wireless communication module connected to the MCU. The device has the following beneficial effects: the device can be carried conveniently;when the maintenance staff approaches live equipment, early warning is carried out to warn the staff to pay attention to the potential danger; portable auxiliary early warning devices carried by other workers also carry out warning simultaneously and thus the other workers arrive at the field timely, so that an electric shock accident caused by the illusion and error of the worker is avoided.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a proximity electric induction group call early warning device. Background technique [0002] In recent years, with the expansion of the grid scale, there are higher requirements for the technical level and safety level of the operators. The "State Grid Corporation Electric Power Safety Work Regulations" stipulates that the safety distance when the equipment department is powered off is: 0.7m for a voltage level of 10kV and below, 1.00m for a voltage level of 35kV, 1.50m for a voltage level of 110kV, and 3.00m for a voltage level of 220kV . Therefore, on the one hand, it is necessary to improve the level of on-site safety measures and strengthen personnel safety training; on the other hand, it is necessary to adopt advanced technology and equipment for early warning to help operators improve safety awareness and avoid personal injury to operators. [0003] During the...
