        產(chǎn)品介紹

        在使用時繼電器必須定期進行檢査維護,檢査時按下列項目進行:

        4.2.1繼電器線圈外加電壓(流)不得超過規(guī)定數(shù)據(jù);電壓線圈不得超過線圈額定電壓的105。/。;電流線圈不 得超過線圈額定電流。

        4.2.2銜鐵緊密地與鐵芯接觸,銜鐵與鐵芯接觸面有塵埃或油垢附著時可用汽油清洗干凈。

        4.2.3磷銅片有機械磨損時必須更換。同時必須注意磷銅片是否緊密地貼在銜鐵上,不得彈起。

        4.2.4觸頭表面燒壞時,必須及時清理或調(diào)換新觸頭,清洗時不允許采用砂紙,可以用汽油清洗或用細銼 刀修理,在修理時銀層應(yīng)盡量少去一些,并不應(yīng)改變觸頭的曲率半徑。

        4.2.5繼電器觸頭的超行程、斷幵距離,壓力等如不符合表4數(shù)據(jù)時應(yīng)調(diào)整達到。

        1?JT3系列繼電器的分類;

        3.1.1按繼電器分:

        JT3-XX電壓(中間)繼電器;

        JT3-XX/1時間繼電器、」T3-XX/3時間繼電器、」T3-XX/5時間繼電器;

        C.JT3-XXL欠電流繼電器;

        注:繼電器型號的二個“XX”第一個表示常幵觸頭數(shù)量,第二個表示常閉觸頭數(shù)量。?3.1.2按吸引線圈的額定電壓及電流分:

        電壓及時間繼電器的線圈有直流電壓:12、24、48、110、220V;

        欠電流繼電器的線圈有直流電流:1.5、2.5、5、10、25、50、100、150、300、600A;?3.1.3按觸頭的種類及數(shù)量分:

        常幵與常閉二種;

        二個、三個及四個觸頭三種。延時繼電器的延時范圍(見表1)。

        表1
