我做過(guò)很多儀器的電箱，一般都很簡(jiǎn)單，就是一個(gè)PLC，一個(gè)步進(jìn)驅動(dòng)器和一個(gè)開(kāi)關(guān)電源。
以前一直沒(méi)出現問(wèn)題，近來(lái)需要儀器開(kāi)一個(gè)晚上，發(fā)現連續運行超過(guò)4個(gè)小時(shí)，儀器就自動(dòng)停了。
後來(lái)發(fā)現晚上空調關(guān)了，環(huán)境溫度大約30-35度，我晚上回去看時(shí)，發(fā)現PLC和驅動(dòng)器溫度都有40-50度。
是不是PLC溫度過(guò)高的時(shí)候會(huì )自動(dòng)停止？
是不是一般電箱都需要裝散熱風(fēng)扇？怎麼裝？
請大家不吝賜教！

配電箱都要安裝排風(fēng)扇散熱
