山東德慶電阻器2P1-31-6/3采用無感繞制的線繞電阻器
在電力設施中的應用:
陶瓷管型啟動式線繞電阻器將固定圈數(shù)成形于陶瓷管上,選擇適當電阻合金線材,順著陶瓷管上旋狀牙溝纏繞,該啟動電阻器功率大且堅固,耐高溫、散熱性優(yōu),電阻溫度系數(shù)小、呈直線變化,適合大電流做短時間過負載時使用,適用于電動機啟動、負載測試、產業(yè)機械、電力分配、儀器設備及自動控制裝置等
電阻器的選型
在高增益放大電路中.應選用噪聲電動勢小的電阻器,如金屬膜也阻器、碳膜電阻器和線繞電阻器。
針對電路的工作頻率選用不同類堪的電阻器。線繞電阻器的分布參數(shù)較大,即使采用無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)對電路工作影響不大,可選用線繞電阻器。
在高頻電路中的電阻器,要求其分布參數(shù)越小越好。所以,在高達數(shù)百兆赫的高頻電路中應選用碳膜電阻器、金屬膜電阻器和金屬氧化膜電阻器。在超高頻電路中,應選用超高頻碳膜電阻器。
