    摘 要：保護(hù)、安自裝置在驗(yàn)收及定檢工作中須測(cè)量動(dòng)作情況及動(dòng)作時(shí)間。對(duì)原保護(hù)出口檢測(cè)裝置進(jìn)行改進(jìn)，增加獲取繼保試驗(yàn)儀故障量起始時(shí)刻功能，可測(cè)得保護(hù)不同時(shí)限動(dòng)作的具體時(shí)間；增加直流電源提供電路，解決保護(hù)裝置出口壓板無(wú)對(duì)應(yīng)直流電源時(shí)儀器無(wú)法檢測(cè)的問(wèn)題；將出口壓板檢測(cè)端子聚類定義，縮減至24路，并開(kāi)發(fā)觸屏功能，可對(duì)各路輸入簡(jiǎn)稱進(jìn)行修改，更靈活地適應(yīng)不同保護(hù)出口壓板情況；更換出口壓板脈沖檢測(cè)電路，提高輸入電阻，使其更為簡(jiǎn)單可靠。

    Abstract: The protection, safety and automatic device needs to measure the action conditions and time in the check, accept and regular checking work. The primary protection export detection device was carried out improvement to increase the function of obtaining fault initial time for relay protection tester, which could measure the specific time for the action of different time about protection, and to increase the direct current (DC) power supply circuits to solve the problem of not detecting for instrument without corresponding DC Power supply for protection device export plate, which could achieve cluster definition of export plate detection terminal, reducing to 24 roads, and developed touch-screen functions. Each input abbreviation could be modified to more flexibly adapt to different situations of protection export plate. The pulse detection circuit of export plate was replaced to improve the input resistance, so as to make it more simple and reliable.
