class="title">詳細(xì)說明</p><div id="parrnea" class="box"><p><p style="text-indent:25px">在微型電子變壓器中，由于匝數(shù)多（數(shù)千匝以上），線徑細(xì)（漆包導(dǎo)線直徑0.1mm以下），在短路數(shù)匝到數(shù)十匝的情況下，與正常的變壓器相比，倍頻倍壓下的測試電流變化沒有有功功率變化明顯（短路10匝一般變化在50%左右），實驗結(jié)果表明，有匝間短路的情況下，變壓器的功率因數(shù)增大，有功功率增大，因此可作為微型電子變壓器匝間短路判定的依據(jù)，更準(zhǔn)確地對變壓器的性能進(jìn)行判斷。因此，電流，浙江2819測試儀，浙江2819測試儀、功率，浙江2819測試儀、功率因數(shù)指標(biāo)都可做為變壓器匝間短路的判定依據(jù)。而且測試儀由于采用感應(yīng)耐壓測試方式，進(jìn)行無損檢測，不對被測試負(fù)載造成破壞，在保證更優(yōu)測試質(zhì)量的前提下，可以更大的提高生產(chǎn)效率，降低原材料損耗。凡可以變?yōu)殡娦?yīng)的周期性物理過程都可以用示波器進(jìn)行觀測。浙江2819測試儀</p><div

耐壓測試儀操作規(guī)程: </p> <p> 1、操作人員應(yīng)經(jīng)生產(chǎn)、技術(shù)部嚴(yán)格培訓(xùn)合格后才能單獨操作，未經(jīng)許可人員嚴(yán)禁使用。 </p> <p> 2、操作者腳下墊絕緣橡皮墊，帶上絕緣手套。 </p> <p> 3、插上電源，按下開關(guān)按鍵。將儀器漏電報警電流設(shè)定為5毫安。 </p> <p> 4、校準(zhǔn)儀器，用700K歐姆陶瓷電阻跨接于底線夾同高壓測試棒之間至儀器報警為準(zhǔn)。 </p> <p> 5、設(shè)定測試條件：電壓3500伏，漏電流5毫安，測試時間為4秒鐘。 </p> <p> 6、測試，測試時接到夾與被測物體可靠相連接，將測試棒緊貼另一端，按下啟動按鍵，觀察測試結(jié)果。如果被測元件超過設(shè)定的漏電流，蜂鳴器報警，則為不合格，按下復(fù)位鍵即可關(guān)閉報警聲，再測試時重新按啟動鍵。 </p> <p> 7、記錄測試結(jié)果。 </p> <p> 8、關(guān)閉電源，取下插頭，做好日常維護(hù)。湖北變壓器匝間測試儀恒流源是一種寬頻譜、高精度交流穩(wěn)流電源，具有響應(yīng)速度快、恒流精度高、能長期穩(wěn)定工作.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江2819測試儀,測試儀" src="https://tyunfile.71360.com/UploadFile/ZRX888/637284369112978516/9563394.png"></div><p style="text-indent:25px">電阻測試儀，是電氣安全檢查與接地工程竣工驗收不可缺少的工具。包括接地電阻測試儀、絕緣電阻測試儀、直流電阻測量儀、表面電阻測試儀以及回路電阻測試儀。回路電阻測量儀（變壓器回路電阻測試儀）適用于測試高低壓開關(guān)的主觸頭接觸電阻值，高低壓電纜線路的直流電阻值等。智能回路電阻測試儀采用100A恒流輸出。極高輸出電壓達(dá)10V（常規(guī)儀器的2-3倍）可采用載面細(xì)的測試線，減輕了現(xiàn)場測試人員的勞動強度。測試過程全部由單片控制自動實施，精度高，復(fù)測性好，單按鍵操作，簡單易行，測試數(shù)據(jù)液晶顯示。適用于不同的工作環(huán)境。</p><p style="text-indent:25px">耐壓測試儀，又叫電氣絕緣強度試驗儀，或叫介質(zhì)強度測試儀，也有稱介質(zhì)擊穿裝置、絕緣強度測試儀、高壓實驗儀、高壓擊穿裝置、耐壓試驗儀等。將一規(guī)定交流或直流高壓施加在電器帶電部分和非帶電部分（一般為外殼）之間以檢查電器的絕緣材料所能承受耐壓能力的試驗。電器在長期工作中，不僅要承受額定工作電壓的作用，還要承受操作過程中引起短時間的高于額定工作電壓的過電壓作用（過電壓值可能會高于額定工作電壓值的好幾倍）。在這些電壓的作用下，電氣絕緣材料的內(nèi)部結(jié)構(gòu)將發(fā)生變化。當(dāng)過電壓強度達(dá)到某一定值時，就會使材料的絕緣擊穿，電器將不能正常運行，操作者就可能觸電，危及人身安全。目前我們經(jīng)常使用的變壓器綜合測試儀一般就是這些型號。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江2819測試儀,測試儀" src="https://tyunfile.71360.com/UploadFile/ZRX888/637284369061689453/3623887.png"></div><p> 耐壓測試儀的基本原理:把一個高于正常工作的電壓加在被測設(shè)備的絕緣體上,并持續(xù)一段規(guī)定的時間,如果其間的絕緣性足夠好,加在上面的電壓就只會產(chǎn)生很小的漏電流。 </p> <p> 在試驗中,樣品在要求的試驗電壓作用之下達(dá)到規(guī)定時間時,耐電壓測試儀自動或被動切斷試驗電壓;一旦出現(xiàn)擊穿,電流超過設(shè)定擊穿(保護(hù))電流,能夠自動切斷輸岀并同時報警,以確定樣品能否承受規(guī)定的絕緣強度試驗。它可以直觀、準(zhǔn)確、快速、可靠地測試各種被測對象的受電壓、擊穿電壓漏電流等電氣安全性能指標(biāo),并能在lEC或**標(biāo)準(zhǔn)規(guī)定的測試條件下,進(jìn)行工頻和直流以及電涌、電力測功機沖擊波等不同形式的介電性能試驗。電子負(fù)載應(yīng)該有完善的保護(hù)功能，保護(hù)功能分為對內(nèi)（電子負(fù)載）保護(hù)功能和對外（被測設(shè)備）保護(hù)功能。浙江2819測試儀</p><p style="text-indent:25px">3250系列變壓器綜合測試儀主機由電源、顯示及驅(qū)動電路、數(shù)字板、記憶卡電路、DCA電流形成電路等組成。浙江2819測試儀</p><p style="text-indent:25px">耐壓測試系統(tǒng)漏電流的測試范圍是0mA ~20mA，測試開始時，被測設(shè)備漏電流通過電流互感器，然后經(jīng)I/V轉(zhuǎn)換電路將采樣電流轉(zhuǎn)換成電壓在單片機內(nèi)進(jìn)行相應(yīng)的A/D轉(zhuǎn)換和計算，終究得到被測設(shè)備在設(shè)定電壓條件下的泄漏電流值，通過和安全標(biāo)準(zhǔn)規(guī)定的泄漏電流值相比較，就可以檢驗設(shè)備耐壓測試是否合格。實際測試時，在電流互感器二次側(cè)設(shè)計了過流保護(hù)電路，當(dāng)有過流情況出現(xiàn)時，例如被測設(shè)備被擊穿或者被測設(shè)備絕緣缺陷，電源迅速被切斷，測試被終止以保護(hù)測試系統(tǒng)不被損壞。浙江2819測試儀</p><p
