A 10kV overhead line intelligent fault monitoring system and its dedicated installation pole

Abstract

The invention relates to the field of power metering facilities, and particularly discloses an intelligent fault monitoring system for 10 kV overhead lines. It includes a fault alarm that can be fixed on the line and has a GPS positioning function. The fault alarm is equipped with a data acquisition and processing unit electrically connected to the line and a wireless transceiver unit connected to the data acquisition and processing unit. The fault alarm The bottom shell of the container, the upper chuck, and the lower chuck are provided with an upper arc-shaped groove on the lower surface of the cross arm of the upper chuck, and a conductive plate is arranged on the lower chuck, and a lower arc-shaped groove is arranged on the upper surface of the conductive plate. When the above-mentioned fault alarm is installed, the line cable is clamped and fixed on the line by the upper arc-shaped groove of the upper chuck and the lower arc-shaped groove of the lower chuck, and the data acquisition and processing unit is connected to the conductive plate through a wire for realizing Line monitoring. The fault alarm of this monitoring system can be installed on the overhead line very conveniently.

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.
