      DZK-200中間繼電器,是上海人民電氣有限公司 http://m.hqbet5695.com 為您提供的關(guān)于DZK-200中間繼電器型號,DZK-200中間繼電器價格,有關(guān)CRC1(CJT1)切換...

    產(chǎn)品介紹

    用途

    本系列中間繼電器用于各種保護和自動控制裝置中,以增加保護和控制回路的觸點數(shù)量和觸點容量。

    型號

     

    結(jié)構(gòu)和原理

    本繼電器的接觸系統(tǒng)由幾種帶頂桿的觸點簧片靈活地組裝成多種觸點形式,但根據(jù)傳統(tǒng)需要情況DZY、DZL、DZJ只取12種觸點形式,而DZB、DZS、DZK型又只取12種中常用的幾種觸點形式。因為觸點是裝在導(dǎo)磁體兩側(cè),為了作用力均勻與造型美觀便將兩側(cè)觸點對稱布置,因此本繼電器觸點組的變化都是成對的增減。

    雖然在規(guī)定的壽命以內(nèi)繼電器的觸點不必更換,但考慮繼電器的使用時間實際是盡可能長的,并且運輸、安裝、使用中都可能發(fā)生意外情況使繼電器損壞,在本繼電器中相對于其它零部件來比,觸點片還是比較容易損壞的,因此將它列為易損件,標(biāo)明圖號,以便使用單位采用。

    根據(jù)繼電保護用的中間繼電器常與信號繼電器同時使用的情況,本繼電器X型產(chǎn)品附有聯(lián)動的動作信號指示與復(fù)歸機構(gòu),并附有一對帶機械保持的動合觸點以接通遠(yuǎn)方信號。即完全可以將聯(lián)用的信號繼電器省掉。這對提高保護裝置的可靠性,簡化接線,降低成本是有一定意義的。

    本繼電器采用一個專用船形支架,其尾部固定底座,中間裝設(shè)繼電器機構(gòu)。不但拆裝靈活,而且去掉底座、外殼,繼電器仍自成一體,在特殊需要時可無底無殼供貨。
