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...
