一、插接式母线槽适用范围


插接式母线槽比较适用于交流三相四线、三相五线制,频率50~60Hz,额定电压至660V,额定工作电流250~6000A的供配电系统,承担配电任务,用于低压配电屏与大、中型负载的连接,主要就是应用于现代化的车间、厂房和高层建筑。该产品是在传统空气型母线槽的基础上进行改进的。插接式母线槽母线导体选用的是高纯度电解铜,导体表面全长都有进行镀锡的处理,提高了导体抗氧化腐蚀能力,加工后再用PVC管热缩处理,相间和对地用绝缘块隔开,铜母排得到双重绝缘保护,绝缘性能提高很大,然后封闭在接地的金属外壳内。


二、插接式母线槽的结构特点


(1)采用对接式安装方式,使得母线槽在安装过程中显得非常便捷、灵活、大大节约了安装时间。


(2)所有电流等级的母线槽都是采用统一的盖板,标准化程度高、互换能力强、变容接口方便。


(3)采用分离空气绝缘式,改善了母线槽的散热性,降低了阻抗,内部绝缘件采用高强度的环氧树脂,提高了母线槽的抗动和热稳定的能力。


(4)通过插接箱分流,可免遭电缆剥皮,连接不安全的苦恼。如你的产品、设备更换,将母线重新组合安装,母线插口分支始终可达到你所需的位置。故使用母线槽配电可令你终身满意。


三、插接式母线槽功能单元介绍:


(1)导体:载流部件采用铜、铝或其合金材料,母排的所有接点和连接处均镀锡。


(2)接头:母线槽接头能确保有足够的接触面和绝缘能力,所有接头螺栓设置均有利于进行安全检查和检修。


(3)绝缘部件


插接式母线槽所选用的绝缘材料都能承受温升试验温度的长期耐热能力,并有较好绝缘能力、机械强度和防老化能力。


(4)外壳


该系列母线槽外壳采用的是成型机辊压成型,体积小外观精美,具备足够的载荷能力,能够起到支撑和保护,避免机械受损。 外壳能保证IP40C以上防护等级,通过母线槽的外壳本身保证良好的接地连续性。外壳材料一般彩用钢板制成,防腐处理有喷漆、喷塑、电镀、热浸锌等等方法。对于4000A以上母线槽,因外壳涡流发热原因,采用铝板或不锈钢板制成。当用户有防腐等特殊要求时,4000A以下的母线槽,也是可以用铝板或者不锈钢板等防腐材料制成。
