Title:
PARALLEL CONNECTING METHOD AND DEVICE FOR MULTI-PATH PARTIAL DISCHARGE SIGNALS
Document Type and Number:
WIPO Patent Application WO/2015/085955
Kind Code:
A1
Abstract:
A parallel connecting method for multi-path partial discharge signals comprises: receiving signals inputted by a plurality of sensors (S201); preprocessing each of the signals to obtain the amplified and filtered signals (S202); performing isolation processing on the amplified and filtered signals (S203) so that the signals can be transmitted in a self-triggered and one-way manner, wherein the delay transmission of ultrahigh frequency partial discharge signals is achieved using a surface acoustic wave delay line set; outputting the signals after the isolation processing in each path (S204). According to the method, the signals can be transmitted in a self-triggered and one-way manner and isolated through the amplification and isolation processing on the multi-path signals, and thus the parallel connection without interference between the multi-path partial discharge signals is achieved, and further the signal loss during the signal transmission process is avoided. Meanwhile, because parallel connected partial discharge detection signals are all fed into a signal bus, a plurality of signals can be simultaneously monitored by one data acquisition apparatus. Consequently, data acquisition by the same set of data acquisition apparatus is realized, and the cost is reduced. A parallel connecting device for multi-path partial discharge signals is also provided.
