7、裝置與傳統(tǒng)檢查發(fā)熱缺陷進(jìn)行分析對(duì)比，總結(jié)了在線測(cè)溫裝置在變電站應(yīng)用的優(yōu)越性、實(shí)用性，并建議在變電站推廣應(yīng)用。關(guān)鍵詞：變電設(shè)備發(fā)熱在線測(cè)溫裝置應(yīng)用1引言在用電緊張、負(fù)荷增長迅速的情況下，變電設(shè)備電氣接觸部分溫度異常幾率不斷上升，但通常發(fā)現(xiàn)設(shè)備電氣接觸部分溫度異常的方法有巡視、紅外測(cè)溫等傳統(tǒng)方法，這些方法存在偏差大、不能及時(shí)或無法直接觀測(cè)發(fā)熱點(diǎn)等缺陷，再者由于變電站無人和少人值班的實(shí)現(xiàn)，巡視、測(cè)溫周期延長，所以按傳統(tǒng)方法檢測(cè)發(fā)熱故障，勢(shì)必造成漏檢、錯(cuò)檢或延誤發(fā)現(xiàn)時(shí)間。如何及時(shí)、正確發(fā)現(xiàn)發(fā)熱故障？這一問題困擾了運(yùn)行管理部門很多年。目前電力工業(yè)技術(shù)發(fā)
