Problems solved by technology

Such complex components plus the electrical connection between each other make the power switchgear sometimes have various failures
[0003] At present, the automation degree of the power switchgear control system is low, mostly simple electrical logic control, which requires on-site manual operation, no human-computer interaction interface indication, no remote network operation, and real-time collection of fault information, environmental information and safety information in the switchgear , there is no scientific alarm and operation and maintenance mechanism, more physical labor is required, there are unsafe factors, and misoperation accidents are prone to occur

Abstract

An Internet of Things cloud configuration switch cabinet intelligent monitoring system comprises a switch cabinet local monitoring device and an Internet of Things monitoring software system, the switch cabinet local monitoring device comprises a core controller, a touch screen, an Internet of Things gateway, a public cloud end (database) and a monitoring platform, and the touch screen is interactively connected with the core controller through the Ethernet. The Internet of Things gateway communicates with the core controller through a Modbus, supports a wired network / WIFI / 4G / 5G mode to upload information to a public cloud end (database) and realizes a cloud configuration function, the monitoring platform comprises a mobile phone and a PC end, and the monitoring platform can access and read the public cloud end (database) and publish a WEB webpage monitoring picture and an APP monitoring interface. According to the invention, convenient operation and scientific management of daily operation and maintenance of the medium-high voltage switch cabinet can be realized, the automation level and intelligent upgrading are realized, and finally, unattended operation of a transformer substation system is realized.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment and Internet of Things monitoring, in particular to an intelligent monitoring system for an Internet of Things cloud configuration switchgear. Background technique [0002] The power switchgear plays a very important role in the power system. Modern power systems have higher and higher requirements for power quality, and correspondingly higher requirements for the reliability and automation of switchgear. A switchgear is a complex system with numerous components inside. The switchgear is mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protection devices. Such complex components plus the electrical connection between each other make the power switchgear sometimes have various failures. [0003] At present, the automation degree of the power switchgear control system is low, mostly simple electrical logic control...
