2、新型小型手拉式推进机构应用于1/2、1/4 抽屉单元,具有三位置锁定、显示、合闸联锁位置辅助电源功能,开关再扣复位功能;
3、抽屉新型推进联锁机构具有分离、试验、连接位置机械显示,电气接点与位置同步。
4、垂直通道:可选用半块功能板或铁制矩形通道,并能方便互换。
1. New-type hand -operated push mechanism (manual and electrical operation) in the way of multi-circle effort- saving push can be used in unitdrawer to realize the relaxed, flexible and smooth push and remove of drawer. Three-position switch is equipped with the function of mechanical positioning and display, as well as position voice prompt. The three-and four-pole drawer pushing 630A is relaxed and flexible; closing interlocking has the function of re-trip resetting with advanced pushing and interlocking technology.
2. New-type tiny manual pushing mechanism applies 1/2 and 1/4 drawer unit with the functions of three-position locking, display, closing interlocking position assistance, and switch re-trip resetting.
3. New-type pushing interlocking mechanism can display separation, test and connection position, and synchronize electrical terminal and position.
4. Vertical channel: It can selec half function board and iron rectangular channel to facilitate exchange.
主要特点 Main Features
1、框架为组合式结构,基本骨架由C型钢材组装而成;
2、每一个柜体分隔为三个室,即水平母线室、抽屉小室、电缆室。高低压成套开关柜各隔室之间用钢板或高强度阻燃塑料功能板相互隔开,上下层抽屉之间有带通风孔的金属板隔离,以有效防止开关元件因故障引起的飞弧或母线与其它线路短路造成的事故;
3、设计紧凑:以较小的空间容纳较多的功能单元;
4、结构件通用性强、组装灵活,以E=25mm为模数,结构及抽出式单元可以任意组合,以满足系统设计的需要;
5、抽屉采用双折边定位槽铆钉铆接工艺,同时双折边、铆钉工艺解决了板材毛刺、自攻螺丝尖伤手的缺陷;
6、抽屉分为1/4 单元抽屉、1/2 单元抽屉和全宽度抽屉(抽屉高度: 6E 8E 12E 16E 24E,E=25mm),所有零部件采用模具一次成型,真正实现同规格抽屉100%互换。
7、仪表板采用开启式空心结构,方便元器件安装、接线及检测,元器件安装空间增大,能满足96mm x 96mm外形的数显表安装,还可以安装其它灯钮等元件,空心处用钢板制作,方便制造开孔;
8、柜体防护等级为IP4X。
