摘 要：二次回路芯線拆除后，主要采用紅色絕緣膠布對裸露的芯線進行包扎處理，隔離工具存在效率低、不規范、不安全等問題。提出嵌套式、布袋式及夾式的芯線隔離工具等三種方式，從絕緣可靠性、現場操作性、阻燃性、開發難度、價格成本、綜合評價等方面進行對比分析后，選取了嵌套式的方案，并從材料、樣式、尺寸等方面進行詳細地設計，實際應用表明，新型隔離工具大大縮短了現場二次芯線隔離的時間，降低了安全隔離工作的脫落率，提高了現場二次安措的可靠性。
關鍵詞：二次芯線；二次安措；隔離工具

Abstract: After demolition of the secondary circuit core wire, the red insulating tape was adopted mainly to carry out bandage treatment for the uncovered core wire. There existed inefficient, irregular and unsafe problems in isolated tool. This paper proposed three kinds of core wire isolated tools including embed, hop-pocketed and clipped modes. Comparison and analysis were made from the aspects of isolated reliability, site operability, fire resistance, developed difficulty, price cost and comprehensive assessment. This paper selected the embed mode as the scheme and designed the material, style and size in detail. The practical application shows that this new type of isolated tool shortens the time of site secondary core wire isolation, reduces the expulsion rate and raises the reliability of secondary safety precaution.
Key words: secondary core wire; secondary safety precaution; isolated tool
