Product Overview:
The system adopts the combined acoustic and electric detection method, that is, by detecting the UHF signal generated by partial discharge, the transient voltage to earth (TEV) and the ultrasonic signal at the same time, the insulation state of the switch cabinet can be monitored. Using a variety of detection technologies, the state of switch cabinet is collected, connected to the acquisition terminal through wireless or wired, after preliminary analysis, the centralized system gives the comprehensive state of switch cabinet in the distribution room. Customization of perception layer, multiple perception units for selection, flexible configuration of different state monitoring units; Network layer mode diversification, a variety of network transmission mode, to meet the different communication requirements of the site; Perfect data analysis technology means, based on a variety of fault type data and environmental noise data, accurate diagnosis, trend prediction and alarm linkage, signal extraction and denoising ability is outstanding.
