Embodiment Construction

[0022] The invention provides an intelligent on-line monitoring system for the partial discharge of a switch cabinet by the ultraviolet method and the ultra-high frequency method. The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 This is the general block diagram of the switchgear partial discharge on-line monitoring system. This system includes three parts: sensor network nodes, data receivers and servers. Sensors are installed in each switch cabinet to form a ZigBee network. ZigBee sensor nodes perform data collection, signal processing, and wireless communication operations, and transmit the discharge information collected in the switch cabinet to the data receiver. The data receiver caches the data all the way and forwards it to the server, analyzes and calculates all the way, and realizes the alarm when an abnormality is found. The server is connected to the external network to realiz...

Abstract

The invention provides a switch cabinet partial discharge intelligent online monitoring system based on an ultraviolet method and an ultrahigh-frequency method. The switch cabinet partial discharge intelligent online monitoring system comprises a sensor network node, a data receiver and a server. The relationship among the modules are characterized in that sensors are mounted in switch cabinets, thereby forming a ZigBee network; a ZigBee sensor node performs data acquisition, signal processing and wireless communication operation; and discharging information which is acquired in that switch cabinet is transmitted to the data receiver. The data receiver performs buffering on one path of data and forwards the data to the server, and performs analysis and calculation on the other path of data; and alarm is realized when an abnormity is found. The server is connected with an outer network, thereby realizing remote, real-time and dynamic monitoring for full-time operation of the whole system. The sensors used in the system have advantages of low power consumption, high reliability, high sensitivity, high linearity, convenient mounting and low fabrication cost. Furthermore the switch cabinet partial discharge intelligent online monitoring system can remotely, intelligently and dynamically monitor partial discharge of the switch cabient in real time.

Description

technical field [0001] The invention belongs to the technical field of electrical detection, and in particular relates to an intelligent on-line monitoring system for partial discharge of a switch cabinet by an ultraviolet method and an ultra-high frequency method. Background technique [0002] High-voltage switchgear is widely used in every link of the power grid. Its safe operation is directly related to the safety of the entire power grid and the quality of power supply from the power system to users. It is one of the most important electrical equipment in the power system. The fault detection in the traditional high-voltage switchgear must be carried out in the state of power failure or by manual inspection. The maintenance of power failure not only reduces the availability of equipment and the reliability of power supply for users, but also can only be carried out periodically. In disrepair and out of control, once a fault occurs, it cannot be dealt with in time. In ad...
