山東魯杯QZX50-1電阻器在低于50kHz 的電路中
、在電力設(shè)施中的應(yīng)用：
1、陶瓷管型啟動(dòng)式線繞電阻器將固定圈數(shù)成形于陶瓷管上，選擇適當(dāng)電阻合金線材，順著陶瓷管上旋狀牙溝纏繞，該啟動(dòng)電阻器功率大且堅(jiān)固，耐高溫、散熱性?xún)?yōu)，電阻溫度系數(shù)小、呈直線變化，適合大電流做短時(shí)間過(guò)負(fù)載時(shí)使用，適用于電動(dòng)機(jī)啟動(dòng)、負(fù)載測(cè)試、產(chǎn)業(yè)機(jī)械、電力分配、儀器設(shè)備及自動(dòng)控制裝置等
電阻器的選型
1.在高增益放大電路中.應(yīng)選用噪聲電動(dòng)勢(shì)小的電阻器，如金屬膜也阻器、碳膜電阻器和線繞電阻器。
2.針對(duì)電路的工作頻率選用不同類(lèi)堪的電阻器。線繞電阻器的分布參數(shù)較大，即使采用無(wú)感繞制的線繞電阻器，其分布參數(shù)也比非線繞電阻器大得多，因而線繞電阻不適合在高頻電路中工作。在低于50kHz 的電路中，由于電阻器的分布參數(shù)對(duì)電路工作影響不大，可選用線繞電阻器。
3.在高頻電路中的電阻器，要求其分布參數(shù)越小越好。所以，在高達(dá)數(shù)百兆赫的高頻電路中應(yīng)選用碳膜電阻器、金屬膜電阻器和金屬氧化膜電阻器。在超高頻電路中，應(yīng)選用超高頻碳膜電阻器。
