特殊情況下兆歐表的串聯(lián)使用

發(fā)布日期:2022-05-29 點擊率:57

  特殊情況下為了解決兆歐表輸出電壓較低這個問題我們可把兩塊1000伏或500伏的兆歐表串聯(lián)起來使用根據(jù)串聯(lián)電壓疊加原理用兩塊1000伏及一塊500伏的兆歐表串聯(lián)就可在被試品上得到2500伏的直流電壓。
  但使用時一定要注意兩點:
  1、只兆歐表的對地電位已被抬高故應(yīng)將兆歐表外殼對地絕緣,沖擊試驗機操作人員應(yīng)采取戴手套等安全措施。
  2、串聯(lián)使用的兆歐表盡量為同一廠家生產(chǎn)這樣特性大體一致。
  另外,有毒氣體檢測儀特殊情況下兆歐表的串聯(lián)使用方法不建議常態(tài)化使用并盡量購買符合測試要求等級的兆歐表進(jìn)行測量。
