主要特点 Main Features
1、开关柜分为四个部分:母线室、功能单元室、电缆室和二次控制线横向接线区。基于常规安全体系要求,用于调试和维护的小室或间隔空间均安装有各自独立的门板。
2、MDmax ST的框架采用自承重框架结构,由双折边的G型材组装而成,骨架上以25mm为间隔排布模数孔,高低压开关柜厂家柜架装配便利而又异常坚固。整个框架由横向和纵向螺栓精确联接,框架结构免维护。骨架、隔板、安装板均采用敷铝锌板制成。
3、开关元件的安装方式有固定式、抽屉式、可移式、插入式,可根据不同要求自由搭配。
4、抽屉式分为1/4单元抽屉、1/2 单元抽屉和全宽度抽屉(抽屉高度: 1U 1.5U 2U 3U, U=200mm ),同规格抽屉可完全互换。
5、抽屉由固定部件和可移动部件(接插件)构成。抽屉固定部件推入开关柜单元小室后,关闭单元小室组件门,插入摇杆,可将抽屉可移部件在隔离、实验和连接三位置之间按序转换。并由带LED的指示窗口显示接插件的位置状态。
6、柜体防护等级为IP40。
