style="font-family: 宋體, SimSun; font-size: 16px;"><br/></span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;">　　第一步是檢查繞組電阻。所以就像萬用表一樣，兆歐表也有一個旋轉(zhuǎn)選擇器，所以把它轉(zhuǎn)到歐姆，然后檢查，引線，這將檢查電氣連續(xù)性。將探頭連接到電機，檢查相間繞組電阻。所以我們必須檢查第一、第二和第三繞組的兩端，為此將探頭連接到第一個繞組，并用另一個探頭檢查它的兩端，對第二和第三繞組做同樣的事情。在執(zhí)行此操作時，我們必須打開兆歐表測試。在此測試期間，所有繞組必須顯示高且?guī)缀跸嗟鹊闹?，然后電機就可以了。</span></p><p><span

16px;"><br/></span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;">　　為了進行這種測試更改，兆歐表設(shè)置為電壓并且電壓電平必須設(shè)置為大于 250V。將兆歐表的一個探頭連接到電機的接地連接。因此可以檢查對地絕緣電阻，然后將第二個探頭連接到第一個繞組并檢查值，然后對第二個和第三個進行檢查，如果所有值幾乎相同，則可以。然后檢查繞組之間的絕緣電阻。</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"><br/></span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;">　　在檢查電機的絕緣電阻時，如果電機正常，三個繞組的值幾乎相同，如果探頭連接到同一繞組，則儀表將顯示為零。</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"><br/></span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;">　　因此，如果電機的絕緣和繞組測試的所有讀數(shù)幾乎相同且高，則電機正常。</span></p><p><br/></p></div> <div id="pvhr3jx3r5" class="inside_newsthree"> <p id="newsprev">上一篇：<b
