適用范圍：
CJ19系列切換電容器接觸器(以下簡(jiǎn)稱(chēng)接觸器)主要用于交流50Hz或60Hz、額定工作電壓至380V的電力線路，供低壓無(wú)功功率補(bǔ)償設(shè)備投入或切除低壓并聯(lián)電容器之用。接觸器帶有抑制涌流裝置，能有效地減小合閘涌流對(duì)電容的沖擊和抑制開(kāi)斷時(shí)的過(guò)電壓。
結(jié)構(gòu)特點(diǎn)：
接觸器為直動(dòng)式雙斷點(diǎn)結(jié)構(gòu)，觸頭系統(tǒng)分上下兩層布置，上層有三對(duì)觸頭與限流電阻構(gòu)成抑制涌流裝置，當(dāng)合閘時(shí)它先接通經(jīng)數(shù)毫秒之后工作觸頭接通，限流觸頭中永久磁塊在彈簧反作用下釋放，斷開(kāi)限流電阻，使電容器正常工作，接觸器內(nèi)部電路連接圖(見(jiàn)圖)。 CJ19-25-43的接觸器有兩對(duì)輔助觸頭，CJ19-63-95的接觸器有三對(duì)輔助頭。接觸器接線端有絕緣罩覆蓋，安全可靠，線圈接線端帶有標(biāo)出電壓數(shù)據(jù)可防止接錯(cuò)。CJ19-25-43接觸器可用螺釘安裝，也可借底部的滑塊扣裝在35mm標(biāo)準(zhǔn)卡軌上。面罩上一個(gè)可拆卸的長(zhǎng)方形小牌，用戶(hù)可用它打印項(xiàng)目代號(hào)等。CJ19-63-95可用35mm或75mm標(biāo)準(zhǔn)卡軌安裝。
