交流耐壓測(cè)試儀又叫電氣絕緣強(qiáng)度試驗(yàn)儀或叫介質(zhì)強(qiáng)度測(cè)試儀。將一規(guī)定交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(yàn)。對(duì)絕緣不良的試品來(lái)說(shuō)是一種破壞性試驗(yàn);電器在長(zhǎng)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(guò)程中引起短時(shí)間的高于額定工作電壓的過(guò)電壓作用(過(guò)電壓值可能會(huì)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。 </p> <p> <br /> </p><p style="text-indent:25px">耐壓測(cè)試儀 PWM控制的理論基礎(chǔ)建立在采樣控制理論的一個(gè)重要結(jié)論上，即：沖量相等而形狀不同的窄脈沖加在具有慣性的環(huán)節(jié)上時(shí)，其效果基本相同。SPWM波形就是把正弦波用等幅不等寬的脈沖代替，脈沖中點(diǎn)與正弦等分中點(diǎn)重合，且與相對(duì)應(yīng)的正弦面積相等，各脈沖的寬度按正弦規(guī)律變化。SPWM波的產(chǎn)生有很多方法，可以由**集成芯片或通用電路組合產(chǎn)生，也可以由單片機(jī)產(chǎn)生。本系統(tǒng)采用單片機(jī)ATMEGA16L產(chǎn)生SPWM波，利用單片機(jī)ATMEGA16L的內(nèi)部的累加器和比較器通調(diào)節(jié)占空比在PC4口輸出SPWM波。廣東交流耐壓測(cè)試儀供應(yīng)商，深圳市茂迪機(jī)電設(shè)備有限公司。</p><div
