Distribution area intelligent operation and maintenance device and operating method thereof

Abstract

The invention discloses a distribution area intelligent operation and maintenance device and an operating method thereof. The distribution area intelligent operation and maintenance device comprises distribution monitoring terminals arranged on each distribution box and intelligent control terminals arranged on each low-voltage branch line and each user meter box, wherein the distribution monitoring terminal comprises a first central processing unit, a first power supply module, a first short message sending and receiving module, a first wireless communication module, a first voltage and current acquisition circuit and temperature sensors which are arranged at the surface of each incoming cable and the surface of each outgoing cable inside each distribution box, and the intelligent controlterminal comprises a microprocessor, a second power supply module, a second short message sending and receiving module, a second wireless communication module and a second voltage and current acquisition circuit, and the first wireless communication modules and the second wireless communication module are wirelessly connected with a power grid monitoring center through a wireless network. The distribution area intelligent operation and maintenance device performs monitoring on the public transformer side, the line side and the client, eliminates a monitoring blind area, can send an early warning short message to a mobile phone of the maintenance personnel and improves the early warning information release speed.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to an intelligent operation and inspection device for a power distribution station and a working method thereof. Background technique [0002] As the end of the power supply in the power system, the distribution network directly communicates with users. Whether the distribution network can operate safely and economically is directly related to the vital interests of the general public, and also directly affects the operating costs and energy-saving goals of the power sector. At present, the monitoring technology used by power supply enterprises still stays in the terminal and only reports data, and the fault information release is operated in the mode of monitoring system forwarding responsibility, resulting in information loss in the GPRS network transmission path or slow release of early warning information. The second is power failure, phase loss, or voltage dro...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the technical problems that the current monitoring system only monitors the public transformer side, which leads to blind spots in the monitoring of the line side and the client end, and the release of early warning information is slow when the equipment fails, and provides an intelligent operation inspection device for distribution stations and Its working method, which monitors the public transformer side, the line side and the client end, eliminates monitoring blind spots, and can send early warning messages to the mobile phones of corresponding maintenance personnel while reporting early warning information to the grid monitoring center, which improves the early warning information. release rate of
