Condition monitoring system used for ring main unit of intelligent power distribution network

Abstract

The invention relates to a condition monitoring system used for a ring main unit of an intelligent power distribution network. The system comprises a data acquisition analysis processing unit, a divide-shut brake current sensor, a divide-shut brake voltage transducer, an operating pressure sensor, a travel sensor, a vibration sensor, a temperature sensor, and a partial discharge sensor, wherein the divide-shut brake current sensor, the divide-shut brake electric pressure transducer, the operating pressure sensor, the travel sensor, the vibration sensor, the temperature sensor, and the partial discharge sensor are accessed to the data acquisition analysis processing unit. The system provides a uniform platform for the power distribution network switch device on-line monitoring system and acquires divide-shut brake electrical current, operating voltage, operating pressure, contact temperature, contact terminal travel, and partial discharge condition of the accessed switches through the switch on-line monitoring device so as to realize on-line monitoring and global analysis for overall conditions of power distribution network switches. Therefore, the on-line monitoring system for the power distribution network switches, which provides uniform data, uniform interface and uniform arrangement and realizes effective data interaction, is provided.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to a smart distribution network ring main unit or a switching station, in particular to a state monitoring system for a smart distribution network ring main unit. Background technique [0002] The existing traditional online monitoring projects of distribution network switches are composed of various independently set software and hardware systems. The online monitoring systems of various projects are deployed as independent systems, and the main problems are as follows: [0003] One is the waste of resources, deploying multiple systems, and each system needs to independently deploy hardware and network, which increases system investment and requires dedicated personnel for management. [0004] The second is information management. The data of multiple systems are independent, and the data of each system does not have a unified format and standard, so it cannot be integrated, and a large...

Problems solved by technology

[0003] One is the waste of resources, deploying multiple systems, and each system needs to independently deploy hardware and network, which increases system investment and requires dedicated personnel to manage

[0004] The second is information management. The data of multiple systems are independent, and the data of each system does not have a unified format and standard, so it cannot be integrated, and a large amount of related data cannot be analyzed in a unified manner.

[0005] The third is equipment diagnosis. The various monitoring information of the switchgear reflects the overall state of the switchgear in an all-round way. Every item that is separated cannot truly and organically monitor the health status and problems of the switchgear.
