font-family: "microsoft yahei"; font-size: 14px;">一兆歐姆相當于1,000,000歐姆。為什么我們需要測量那么高的阻力？不要考慮測量電阻，而應將其視為測試設備。它專門測試電機繞組的絕緣性。根據(jù)電機的絕緣等級，良好的電機可以很好地測量兆歐姆或1,000,000,000,000歐姆！</p><p

transparent; -webkit-appearance: none; margin: 0px; padding: 0px; font-family: "microsoft yahei"; font-size: 14px;">這是電機繞組的絕緣測試，通常稱為兆歐表，兆歐表或兆歐表電機。我們正在測試電機的絕緣，更具體地說是電機繞組和電機外殼之間的絕緣。如果流過一小部分電流，則可以通過這些高度敏感的儀表進行測量。電機絕緣的額定和制造能夠承受不同的溫度。時間和熱量會破壞電機的絕緣性。正確使用兆歐表將測試任何電機絕緣。根據(jù)您所測試的絕緣等級，將對儀表應讀取的歐姆數(shù)量產(chǎn)生影響。要測試絕緣，您應該使用能夠測試兆歐姆的兆歐表。否則您的測試可能不可靠或不準確。</p><p

font-size: 14px;">三階段培訓使上述視頻成為所有人都可以使用的免費工具。我們希望這段視頻能夠清楚地了解如何以及為何使用這些儀表。當正確使用兆歐表時，您將能夠輕松識別絕緣損壞。請記住，熱量會損壞電機絕緣，因此如果您不確定剛剛測試過的電機，請在使用時再次測試電機。如果每次都獲得較低的電阻讀數(shù)，則應盡快停止使用電機。</p><p
