CM1常熟开关断路器主要安装在低压配电柜中作主开关,用于控制和保护配电网络。其技术性能达到了国际上同类产品九十年代先进水平。符合IEC947-2、GB14048.2《低压断路器》标准。
1.使用条件
周围空气温度为-5°C~+40°C,且24h的平均值不超过+35°C(特殊订货的除外);
安装地点的海拔不超过2000m;
空气相对湿度在最高温度为+40°C时不超过50%;在较低温度下可以有较高的相对湿度,最湿月的月平均最低温度不超过+25°C,该月的月平均最大相对湿度不超过90%,并考虑因温度变化发生
在产品表面的凝露;
污染等级为3级。
2.结构特点简介
触头系统
每相触头安装在绝缘小室内。触头系统采用了多片触头并联形式的结构、减小了触头系统的惯性,保证了断路器的高分断能力。
操作机构
安装在断路器中央,与主电路隔离;断路器由弹簧贮能机构进行闭合操作,闭合速度快。操作机构兼有电动及手动贮能、闭合、断开。
所有附件整个系列通用。
抽屉座
摇动抽屉座下部横梁上手柄,可实现断路器的三个工作位置(手柄旁有位置指示);
“连接”位置:主回路和二次回路均接通,此时隔离板开启;
“试验”位置:主回路断开。并由绝缘隔离板关闭隔开,仅二次回路接通。可进行必要的动作试验;
“分离”位置:主回路与二次回路全部断开,此时隔离板关闭;
抽屉式断路器具有可靠的机械联锁装置,只有在连接位置和试验位置时才能使断路器闭合;
断路器共有47个二次回路接线端子;
相同额定电流的抽屉式断路器(包括本体和抽屉座)具有互换性。
3.智能控制器的选择
智能控制器分为以下三种:电子型、标准型、通讯型。
基本功能
过载长延时反时限保护;短路短延时反时限保护;短路短延时定时限保护;短路瞬时保护;接地故障保护功能;整定功能;过载报警功能;试验功能;电流显示功能;自诊断功能;热模拟功能;故
障记忆功能;触头损耗指示;MCR功能;
选择功能(用户按需要订货时选择)
电压显示功能;负载监控功能;
通讯型控制器通过RS485实现双向传输各功能参数,通讯规约按企业规定或用户与企业协商。
