    摘  要:介紹一種可溯源的沖擊電壓校準器,該校準器可輸出IEC 60060-1——2010《高電壓試驗技術第一部分:一般定義和試驗要求》中所規(guī)定的標準雷電全波、雷電操作波等4種時間參數(shù)波形,可作為標準波源對數(shù)字記錄儀及沖擊峰值表進行校準。該校準器可通過理論分析的方式溯源至各元器件的國家標準,其輸出電壓峰值不確定度<0.1%,時間參數(shù)不確定度<0.5%,可滿足實際應用中對沖擊電壓峰值表及沖擊測量用數(shù)字記錄儀的幅值及時間測量參數(shù)校準的需求,具有很好的實用性及較高的推廣價值。
    關鍵詞:可溯源;標準波源;數(shù)字記錄儀;沖擊峰值表

    Abstract: This paper introduces a traceable impulse voltage generator which can generate standard lighting impulse and switch impulse waveforms according to IEC 60060——1∶2010. It is used to calibrate the time parameters and peak value for digital recorder and digital peak value voltmeter. The estimated uncertainty for the impulse peak value is less than 0.1% and for time parameters, lass than 0.5%. It can be traced to national compnent standard by theoretical analysis. It can satisfy the parameters calibration requirements of digital voltmeter and digital recorder used for measuring lighting waveform. It is of great practical use and can be used widely in impulse measurement calibration.
    Keywords: traceable; standard waveform generator; digital recorder; peak value volmeter
