A New Technology And Prototype For Construction Safety Nearly High Voltage

In recent years, because the high-altitude construction machinery equipment as too close to high voltage electric, caused the short-circuit trip accident frequently. Some of them caused widespread power outages. The national economy suffered a serious loss of production. The life and social activities of people have a great impact.This article introduced the calculation and the computer simulation of electric field for AC transmission lines. Calculate the induced current of spherical field induction sensors by theory. Test the performance of alarm devices in laboratory conditions.?Correct the alarm devices by standard field.?Wireless Alarm devices near high voltage electric through the Electric field sensors is based on the surface of metal can induce electric charge in electric field. Turn the electric charge on the surface of metal into the single of current by the selected frequency filtering of 50Hz, and enlarge the induced current signal. The type of MCU is AVR mega 48, transform the results of the measurement into the information of distance by MCU. Send the alarm information to the alarm host through wireless communication module APC220-43, according to the received instruction information to make sound and light alarm to alert operating person, in order to avoid the accident of electrical shock. It has been put the device into use in Guangzhou Power Supply Bureau and other units, and got a better evaluation.
