A Voice Alarm System Applied To Hot-Line Work Of Distribution Lines

In recent years,the development of the power system tends to be intelligent and informational.As an important part of the power system,the distribution line connects the power grid and the users,and provides the power to the users.The problem of security and maintenance directly affects the people’s production and life.In order to ensure the safe operation of the distribution line,the operator needs to carry on the live operation to maintain the equipment and eliminate the fault of the line,but with the danger of the maintenance activities,such as the high voltage electric shock can not be ignored-Therefore,it is very necessary to improve the safety and troubleshooting efficiency of operators.This topic analyzes the safety problems existing in the distribution system,and considers that the existing live working is still difficult to grasp the safety distance.In non overhaul state,short circuit fault caused by animal or human activity is also complicated.A voice warning device,which can detect the safe distance,is used to assist the live worker to perform safe operation,and record the whole activity process,and monitor and maintain online through the form of data uploading.At the same time,in the non-maintenance state,it dynamically records the distance of the birds or climbing people on the distribution lines,uploads the data on line,and assists the alarm of the electric shock and the short circuit fault detection.The warning system of this distribution equipment carries out the voice warning to the maintenance personnel close to the equipment through the monitoring equipment.At the same time,the system is equipped with Bluetooth module,and the maintenance personnel can use Android mobile phone with Bluetooth to operate the early warning device wireless,perform access to device information,switch voice prompts,change device parameters and other operations.In the unmanaged place,the system can detect the personnel of error,timely voice warning,send early warning information to the manager and remote host,and the remote monitor can check the parameters of each warning device online,and find the equipment abnormity in time.Compared with traditional timing maintenance,the workload of maintenance personnel is greatly reduced.
