【摘要】：為適應(yīng)超高頻(UHF)局部放電在線監(jiān)測需要,設(shè)計了一種基于層疊式多臂Hilbert分形天線與電平掃描式采集系統(tǒng)的局部放電超高頻監(jiān)測智能傳感器。通過在傳統(tǒng)Hilbert分形輻射臂上增加寄生臂條以及引入層疊式貼片結(jié)構(gòu),設(shè)計了小尺寸、寬頻帶、高增益的層疊式多臂Hilbert分形天線作為智能傳感器天線;并根據(jù)電平掃描式法開發(fā)了電平掃描式數(shù)據(jù)采集模塊作為智能傳感器數(shù)據(jù)采集單元。在實驗室內(nèi)進(jìn)行空氣中的針 板放電實驗,并同時采用智能傳感器和全波形采集法采集信號。結(jié)果表明,該傳感器實現(xiàn)了超高頻局部放電信號的高速處理,直接輸出局部放電譜圖,其輸出數(shù)據(jù)量小,硬件簡單成本低,設(shè)備體積小。2種采集方法得到的放電譜圖相似程度高,驗證了智能傳感器能夠準(zhǔn)確地獲取并處理局部放電信號。
[Abstract]:In order to meet the need of UHF partial discharge on-line monitoring, an intelligent sensor based on stacked multi-arm Hilbert fractal antenna and level scanning acquisition system is designed. By adding parasitic arm bars to the traditional Hilbert fractal radiating arm and introducing the stacked patch structure, a small, wide band, high gain stacked multiarm Hilbert fractal antenna is designed as a smart sensor antenna. According to the level scanning method, the level scanning data acquisition module is developed as the intelligent sensor data acquisition unit. The discharge experiment of the needle plate in the air was carried out in the laboratory, and the intelligent sensor and the whole waveform acquisition method were used to collect the signal. The results show that the sensor can process the UHF PD signal at high speed and output the PD spectrum directly. The output data is small and the hardware simple cost is low. The similarity of the discharge spectrum obtained by the two methods is high, which verifies that the intelligent sensor can accurately acquire and process partial discharge signals.
