Abstract

The invention discloses an electric power circuit fault detecting system which is used for detecting electric power circuit faults and conducting remote alarming. The electric power circuit fault detecting system comprises a digital fault indicator, a data collector and a main controller. The digital fault indicator is used for detecting real-time data of the electric power circuit and outputting state information of the electric power circuit according to the real-time data. The data collector and the digital fault indicator form a communication network through short-distance wireless modulation, and the data collector is used for collecting the state information sent by the digital fault indicator and turning the state information into a data packet. The main controller is used for receiving the data packet sent by the data collector and judging fault points and types according to information in the data packet. The electric power circuit fault detecting system can achieve remote alarming of the electric power circuit faults and detecting of various electric power circuit faults.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a power line fault detection system. Background technique [0002] The power line fault indicator is a device used in transmission and distribution lines, power cables and switchgear inlet and outlet lines to indicate the flow of fault current. Once a fault occurs on the line, the line inspectors can use the alarm display of the indicator to quickly determine the fault point and eliminate the fault, changing the backward practice of blindly inspecting the line and switching on and sending power in sections to find faults in the past. However, the traditional fault indicator adopts analog circuit technology and small shell packaging design, the realization function is too simple, the type of fault detection is too single, and it needs on-site inspection by line inspectors, and it is impossible to realize remote fault alarm. limitation. Contents of the invention [0003] Th...
