③ 摘要
國(guó)家標(biāo)準(zhǔn)以及IEC標(biāo)準(zhǔn)將ATSE分類為PC級(jí)和CB級(jí)兩個(gè)級(jí)別，由于CB級(jí)ATSE存在著體積大，動(dòng)作速度慢，機(jī)械聯(lián)鎖可靠性較差等缺點(diǎn)，其應(yīng)用領(lǐng)域正在逐步縮小，而PC級(jí)ATSE由于其結(jié)構(gòu)簡(jiǎn)單，體積小，自身聯(lián)鎖，轉(zhuǎn)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(guò)程、發(fā)展趨向及PC級(jí)ATSE在工程中的應(yīng)用入手，對(duì)PC級(jí)ATSE進(jìn)行了必要的闡述。 關(guān)鍵詞： ATSE雙電源自動(dòng)轉(zhuǎn)換開(kāi)關(guān)；機(jī)械聯(lián)鎖；電氣隔離； 延時(shí)設(shè)定；無(wú)標(biāo)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.
