Intelligent fault monitoring system for 10 kV overhead line and special mounting rod of intelligent fault monitoring system

Abstract

The invention relates to the field of electric power metering facilities, and particularly discloses an intelligent fault monitoring system for a 10 kV overhead line. The intelligent fault monitoringsystem for the 10 kV overhead line comprises a fault alarm which can be fixed to the line and has a GPS positioning function. A data acquisition and processing unit electrically connected with the line and a wireless transmitting-receiving unit connected with the data acquisition and processing unit are arranged in the fault alarm. The fault alarm comprises a bottom shell, an upper clamping head and a lower clamping head, an upper arc-shaped groove is formed in the lower surface of an cross arm of the upper clamping head, a current-conducting plate is arranged on the lower clamping head, and alower arc-shaped groove is formed in the upper surface of the current-conducting plate. When the fault alarm is installed, a line cable is clamped and fixed to the line through the upper arc-shaped groove of the upper clamping head and the lower arc-shaped groove of the lower clamping head, and the data acquisition and processing unit is connected with the current-conducting plate through an electric wire for completing monitoring of the line. The fault alarm of the monitoring system can be conveniently installed on the overhead line.

Description

technical field [0001] The invention relates to the field of power metering facilities, in particular to an intelligent fault monitoring system for 10 kV overhead lines, and provides a special installation rod for installing the monitoring system. Background technique [0002] In the fault detection of 10 kV overhead lines, it is necessary to use the corresponding fault alarm. The fault alarm is generally installed on the cable of the overhead line. The detection and judgment of the current and / or voltage and / or grounding data on the cable are realized through the built-in detection module, transceiver module, alarm module, etc. In case of failure, the signal is sent to the control terminal to monitor the line failure. [0003] At present, the existing fault alarms are generally fixed on the cables by spring clips. When installing on overhead lines, operators generally need to manually install them on the tower poles. The defects are as follows: [0004] The installation p...

AI Technical Summary

Problems solved by technology

[0004] The installation position is not flexible enough (it can only be installed near the tower pole, and when it is far away from the tower pole, the operator cannot stand on the tower pole for installation); the labor intensity is high, the degree of danger is high, and the operation is inconvenient when working at heights; due to the detection The alarm is generally suspended on the line, and the installation method of the spring clip is not firm enough. When the alarm is shaken, it is easy to fall off or move on the line, resulting in inaccurate detection signals.
