配電房電力設(shè)備是輸配電網(wǎng)中的樞紐和通道，設(shè)備在使用的過(guò)程中會(huì)有老化、失修、故障危險(xiǎn)等狀況呈現(xiàn)。但是這些狀況并不能都靠人眼、工作人員的經(jīng)驗(yàn)一一排除，必需要專門的電力設(shè)備檢測(cè)才干檢查出這些電力安全危險(xiǎn)并組織人力及時(shí)排除。 </p> <p> 配電房電力設(shè)備防范性實(shí)驗(yàn)是指對(duì)已投入作業(yè)的設(shè)備按規(guī)矩的實(shí)驗(yàn)條件（如規(guī)矩的實(shí)驗(yàn)設(shè)備、環(huán)境條件、實(shí)驗(yàn)辦法和實(shí)驗(yàn)電壓等）、實(shí)驗(yàn)項(xiàng)目、實(shí)驗(yàn)周期所進(jìn)行的守時(shí)檢查或?qū)嶒?yàn)，以發(fā)現(xiàn)作業(yè)中電力設(shè)備的危險(xiǎn)、防范發(fā)作事端或電力設(shè)備損壞。它是判斷電力設(shè)備能否持續(xù)投入作業(yè)并確保安全作業(yè)的重要措施。
