| titleOfInvention | Parallel connection method and device for multi-channel PD signals |
| abstract | A parallel connection method and a device for multi-channel partial discharge (PD) signals have input sources of pre-processed and amplified signals received by multiple PD sensors. Then isolation and processing are provided to the signals to ensure that each signal is able to be self-triggered and unidirectional transmitted. Finally, processed signals of each channel are outputted. For ultra-high frequency (UHF) PD signal, the delay transmission is realized by a surface acoustic wave (SAW) delay line method. The present invention makes the amplified multi-channel PD signals self-trigger and unidirectional transmit though isolation processing and then realizes parallel connection without interference. The method also decreases signal transmission loss. Meanwhile, all the detected PD signals transmit on one signal bus through parallel connection method, so as to use only one set of acquisition unit to monitor and acquire the signals received by multiple sensors, which obviously lowers the system cost. |
