Abstract

The invention relates to a portable power distribution network fault positioning device, and the device comprises a fault detector body and two detection clamping heads. The interior of the fault detector body is provided with a first active filter and a second active filter, and the first and second active filters are respectively connected with two detection clamping heads through wires. The interior of the fault detector body is also provided with a PLC controller and a signal amplification circuit. The device is simple in structure, is ingenious in design, is convenient to use, achieves the connection of the wires in a power grid through two detection clamping heads, and then injects a low-frequency AC signal to a fault phase. When a detection signal is not returned, it indicates that there is not obstacle; when the detection signal is returned, it indicates that a fault point is located in the front, and a flashing lamp and a loudspeaker are started to give an alarm, thereby achieving the better prompt for a user. Moreover, the device can protect the user from being damaged by the electric shock, and protect the personal safety of the user.

Description

technical field [0001] The invention relates to the technical field of low-voltage distribution network fault location, in particular to a portable distribution network fault location device. Background technique [0002] Distribution network lines are complex and have many branches. Once a fault occurs, it is difficult to detect and locate it. According to statistics, more than 95% of power outages suffered by power users are caused by distribution network failures. Therefore, accurately locating the location of the distribution network fault is of great significance for isolating and repairing the fault in time and improving the reliability of power supply. [0003] The existing distribution network fault detection device cannot realize fast and accurate detection of distribution network faults, and the current existing distribution network fault remote location system consists of a fault location indicator device and a remote transmission device for collecting data from ...
