③ 摘要
國家標準以及IEC標準將ATSE分類為PC級和CB級兩個級別，由于CB級ATSE存在著體積大，動作速度慢，機械聯(lián)鎖可靠性較差等缺點，其應用領域正在逐步縮小，而PC級ATSE由于其結構簡單，體積小，自身聯(lián)鎖，轉換速度快，安全，可靠已成為ATSE的主流。本文正是從ATSE的發(fā)展過程、發(fā)展趨向及PC級ATSE在工程中的應用入手，對PC級ATSE進行了必要的闡述。 關鍵詞： ATSE雙電源自動轉換開關；機械聯(lián)鎖；電氣隔離； 延時設定；無標題文檔。

The national standards as well as the IEC standard the ATSE classification are the PC level and the CB level two ranks, because CB level ATSE has the volume to be big, the movement speed is slow, the mechanical interlocking reliability inferior shortcoming, its application domain is reducing gradually, but PC level ATSE because its structure is simple, the volume is small, own interconnection, the conversion rate is quick, safe, reliable has become ATSE the mainstream. This article is precisely from the ATSE developing process, the development trend and PC level ATSE obtains in the project application, has carried on the essential elaboration to PC ⅠⅠlevel ATSE. Key word: ATSE double power source automatic change-over; Mechanical interlocking; Electrical isolation; Time delay hypothesis; Non-title documents.
