Abstract

The invention discloses a remote electric leakage locating and detecting device for low voltage overhead lines and belongs to the technical field of electric power equipment detection. The remote electric leakage locating and detecting device is provided with a cross-core type current transformer, a filter circuit, an operational amplifier circuit and an MCU main chip, wherein the MCU main chip is respectively connected with a storage circuit, a key input circuit, an RS485 circuit, an alarm circuit and a power source processing detection circuit. The RS485 circuit is connected with a wireless transceiver module. The remote electric leakage locating and detecting device can carry out remote detection without being influenced by external magnetic field interference, and has the advantages of accurate measurement and rapid speed. Current leakage can be checked to eliminate hidden dangers current leakage points to avoid electric shock, fire and other safety accidents which have serious impact on personal and property safety.

Description

technical field [0001] The invention belongs to the technical field of electric equipment detection, and relates to a detection device, in particular to a low-voltage overhead line leakage remote location detection device which is used for location detection of low-voltage line leakage and is suitable for remote location detection of overhead line leakage. Background technique [0002] In recent years, with the construction of new rural areas, the continuous transformation of rural power grids, and the wide application of residual current-operated protectors have improved the protection of residual current-operated protectors for lines in the station area, the ability to analyze fault causes and effectively reduce the scope of faults. From the current In terms of the operation of the residual current operated protector, although there is a system monitoring system, most of the monitoring is only in the scope of the general insurance and some are extended to the middle insuran...
