class="source"><span>日期：2025-04-14</span><span>瀏覽：56次</span></p> <div> <p><strong>如何更好的使用真空開關(guān)真空度測試儀</strong></p><p>真空開關(guān)真空度測試儀以單片計(jì)算機(jī)為主控單元，測試過程實(shí)現(xiàn)自動(dòng)化，在原理上改變了國內(nèi)外同類產(chǎn)品采用電流峰值做標(biāo)定的方法，而采用離子電荷來做標(biāo)定，有效地抑制了測試過程中脈沖電源的干擾，使測試更為穩(wěn)定可靠。</p><p>為了保證真空開關(guān)真空度測試儀測量數(shù)據(jù)的精準(zhǔn)，在測量時(shí)一定要注意以下事項(xiàng)：</p><p>1、真空開關(guān)真空度測試儀外殼應(yīng)可靠接地；</p><p>2、為了提高測量準(zhǔn)確度，測試前應(yīng)將真空開關(guān)外表面擦試干凈；</p><p>3、請(qǐng)正確選擇真空管的管型；</p><p>4、測試過程中，高壓輸出端會(huì)輸出約20kV高壓，請(qǐng)保持其與人體及低壓線端的絕緣距離(建議與人體保持 0.5米以上距離) ，磁場電壓輸出端輸出約1600V高壓，請(qǐng)注意安全!</p><p>5、儀器進(jìn)行試驗(yàn)時(shí)，接線應(yīng)先連接磁控線圈、真空管的連線，然后再與儀器相連。測試完成后拆線應(yīng)先拆除與儀器相連的測試線，然后再拆除與磁控線圈、真空管的連線；如在使用時(shí)忘記連接磁控線圈而直接按測量鍵時(shí)，應(yīng)立即關(guān)閉電源，重新接好磁控線圈，請(qǐng)注意此時(shí)磁場電壓輸出端會(huì)有較高電壓，請(qǐng)接線時(shí)勿接觸導(dǎo)體部分，以免被電容上的殘余電壓擊傷。</p><p>6、測量完畢后磁場輸出端仍可能有 40V左右的殘余電壓，請(qǐng)注意安全！</p><p>7、測試過程中，若出現(xiàn)異常，請(qǐng)首先關(guān)閉電源，與廠家聯(lián)系，請(qǐng)勿自行打開機(jī)箱!</p><p><br/></p> <div id="iqaqewgi6e" class="clear"></div> </div> <div id="iqaqewgi6e"
