Cable fault positioning on-line monitoring device and method

Abstract

The invention provides a cable fault positioning on-line monitoring device. The device comprises a traveling wave current sensor, an electricity taking current sensor, a monitoring terminal, a communication module and a background terminal. The traveling wave current sensor and the electricity taking current sensor are installed on a to-be-tested cable. The traveling wave current sensor and the electricity taking current sensor are connected with the monitoring terminal. The monitoring terminal is connected with the background terminal through the communication module. The monitoring terminalcomprises an ARM processor and a DSP chip, the ARM processor is connected with the DSP chip, the communication module is connected with the ARM processor and the background terminal, the ARM processoris connected with the background terminal through the communication module, and the DSP chip is connected with the traveling wave current sensor. According to the cable fault positioning on-line monitoring device provided by the invention, the ARM processor and the DSP chip are used for processing and acquiring the current data, so that the high efficiency of the operation efficiency and the stability of the performance of the cable fault positioning on-line monitoring device are ensured.

Description

technical field [0001] The invention relates to the field of cable monitoring, in particular to an on-line monitoring device and method for cable fault location. Background technique [0002] In the power system, the power cable, as the primary equipment for transmitting and distributing electric energy, is prone to failure due to external natural conditions during use. With the increasing use of power cables in the power system, the need to accurately find the location of cable faults is becoming more and more urgent. The current mainstream cable insulation and fault monitoring methods are mostly offline monitoring during cable maintenance, and real-time online monitoring cannot be achieved, which leads to insufficient timely and effective handling of cable faults. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, one of the purposes of the present invention is to provide an online monitoring device for cable fault location, which...
