CKJ5系(xi)列真空交流接触器(qi)，其(qi)集电(dian)(dian)(dian)真空、机械(xie)电(dian)(dian)(dian)磁开关为一体的(de)真空接触器(qi)，不但通断(duan)能力强(qiang)，维修(xiu)量小、电(dian)(dian)(dian)弧不外露，电(dian)(dian)(dian)触头不受大气粉尘和腐(fu)蚀性气体的(de)影响，接触电(dian)(dian)(dian)阻稳定(ding)、防爆性能好(hao)、安全可靠、体积(ji)小、重量轻、噪声低、长(zhang)使用(yong)寿命；产品适用(yong)于煤炭(tan)、石油、化工、冶(ye)金(jin)、电(dian)(dian)(dian)力、机械(xie)、交通等领(ling)域用(yong)于控制(zhi)三相交流电(dian)(dian)(dian)动机或通断(duan)其(qi)他电(dian)(dian)(dian)气负载。
目(mu)前市场现有的CKJ5系列(lie)真空接触(chu)器(qi)，辅助节能(neng)开关(guan)仍(reng)采用(yong)电(dian)(dian)弧(hu)空气外露的机械开关(guan)，因(yin)其(qi)分断的是电(dian)(dian)压较高的直(zhi)流(liu)电(dian)(dian)流(liu)，分断电(dian)(dian)弧(hu)大，极易(yi)烧损(sun)辅助节能(neng)触(chu)点(dian)，造成(cheng)触(chu)点(dian)接触(chu)不良，引(yin)起接触(chu)器(qi)启动异常(chang)烧线圈负载等，操作(zuo)电(dian)(dian)寿命(ming)短，同时防爆性能(neng)也欠佳；
真空(kong)交(jiao)流接触器常见故障(zhang)
1、 CKJ5─400型真空接触(chu)器通电(dian)(dian)瞬(shun)间(jian)铁心吸合不上(shang)，产生跳跃(yue)。线圈回(hui)路(lu)电(dian)(dian)容击穿，造(zao)成加在维持(chi)线圈上(shang)的电(dian)(dian)压是(shi)一个波动的直(zhi)流，解决(jue)方法：更换质(zhi)量较好(hao)的电(dian)(dian)容1.2uF/1000V
2、 CKJ5─400型(xing)真空接触器通电不长时间（20分(fen)钟左右）线(xian)圈整(zheng)流回路多个元件烧(shao)毁(hui)，造成真空接触器跳开(kai)。通过检查发现整(zheng)流桥内的二极(ji)管(guan)结构是面接触型(xing)的。
