                    CKJ5、CKJ系列真空接触器                             使用说明书                             CKJ5、CKJP系列真空接触器适用于交流50HZ，额定工作电压至1140V，额定工作电流125—400A的电力网络，供直接或远距离接 通和分断主电路之用。因主触头在高真空环境中工作，因此居有电弧不外露、体积小、重量轻、寿命长、维修周期长等优点，特别适宜于组成各种路灯控制器及工作 于油田、化工等场合。                            1、 工作条件                             1． 海拨高度不超过2000米。                            2． 环境空气温度：-25～+40℃。                            3． 空气相对湿度：环境空气温度为+25℃时不超过50％，在较低温度下可以有较高的相对湿度。最湿月份的平均温度为+25℃时，月平均最大相对湿度为90％。                            4． 安装面与垂直面的倾斜度不超过15°。安装类别通常为第Ⅲ类。                            5． 环境污染等级为3级。                            6． 振动不大于30米/秒的场。                            接触器由真空开关管、绝缘架，动臂、磁路支撑架、电磁操作机构及整流装置组成。电磁操作机构由铁心、线圈、磁极板、衔铁板、转轴、动臂等组成。                                        真空开关管静导电板通过螺钉固定在绝缘架上，绝缘架与左右支撑板及磁路支撑架用螺钉联结。当线圈通电后衔铁吸合，带动动臂和动导杆等，使真空开 关管动触头运动，与静触头接触，使接触器处于闭合状态。当线圈断电后，在反力弹簧作用下衔铁板释放，动静触头分离使接触器处于分断状态。                                        电磁操作机构由铁心、线圈、磁极板、衔铁板、转轴、动臂等组成。                                        辅助触头位于衔铁板一端，由衔铁上下运动带动辅助触头运动。                                        2、安装、调整及更换天关管                                         1． 安装                                        ⑴ 安装前应检查安装平面，安装面不平时用垫片调整。                                        ⑵ 用螺钉加防松垫圈将接触器固定在安装板上。                                        ⑶ 接好主回路进出线，将交流控制电源线接在接线端子上，并接好地线。                                        2． 调整                                        当触头参数不符合要求或更换真空开关管后需作如下调整：                                        ⑴ 松开球面接头锁紧螺母。                                        ⑵ 转动球面接头法兰，使触头刚刚断开（用万用表低阻档测）并反复调整，使三                                        管保持一致。                                        ⑶ 顺时针转动球面接头到法兰，使开距达到标准要求。                                        ⑷ 拧紧动法兰锁紧螺母。由于结构尺寸上保证，超程不必再调整。                                        ⒊ 更换真空开关管                                        当真空度下降或其他原因损坏时需更换真空开关管。                                        ⑴ 当动静触头分开状态下，用2500V兆欧表测动静触头间绝缘电阻小于60兆欧时                                        应更换真空开关管。                                        ⑵ 拧松主电路与软联接线连接螺钉，脱开软联接线。                                        ⑶ 拧下静导电板绝缘框的螺钉。                                        ⑷ 向动端压缩触头弹簧将销钉转90度。                                        ⑸ 将真空开关管组件取下。                                        ⑹ 卸下球面接头组件，取下开关管。                                        ⑺ 将待换的真空开关管按上述相反顺序安装到接触器上。拧紧锁紧螺母时，注意不                                        使波纹管处于扭曲状态。更换开关管后要重新调节开距。                                        3、使用与维修                                         1． 接触器的工作电压及工作电流不应超过额定值 2． 对新换的真空开关管要事先检查其真空度。要求在10-2帕（10-4托）以上。可                                        用工频耐压法检查：触头间距在标准要求范围内，要求耐压8KV以上（经三次试验后，不允许有击穿或连续闪络现象）。                                        3． 平时建议用2500V兆欧表检查。当绝缘电阻小于100M 时应加强监视。小于60M                                        时应更换真空开管。检查时应区分陶瓷表面受潮或其他原因引起的绝缘下降。                                        4． 在小负荷感性负载使用真空接触器时，建议配用RC阻容吸收盒，接入接触器主                                        电路负载侧。                                        5． 凡属下列情况之一时应对接触器作全面检查和调整。                                        ⑴ 每年一次例行检查和清洁工作。                                        ⑵ 动作一万次以后。                                        ⑶ 真空开关管损坏后。                                        检查及调整内容：                                        ⑴ 真空开关管真空度。可用工频试验法。                                        ⑵ 辅助触头触点接触情况。接触不良要调换新触头或以维修。                                        ⑶ 检查开距及三管同步。                                        ⑷ 所有螺钉螺母有否松动。活动部位有否卡住现象。                                        ⑸ 绝缘耐压程度检查，用测试仪或2500V兆欧表。
