Description

用于致动电力设备的开关装置的电力远程驱动器和远程驱动 器组件
技术领域
本发明涉及一种电力远程驱动器,用于致动安装在顶帽式轨道上的电力设备的开关装置,并且涉及一种远程驱动器组件。
背景技术
安全可靠的电源供应为私营部门、公共部门、特别是工业部门中轻松无忧的经济运行奠定了基础。然而,随着电力设备的日益复杂化,需要采取足够的保护措施来满足有关电力安全和断电安全的需求。
为了标准的设置和监测电源供应,电力设备设有开关装置,例如过电流保护装置、断路器或负荷隔离开关。关于设备的可用性及其电力安全性,如果电源供应的一部分(例如在子网中断期间)不再得到保证,则必须可以获得仍然能够控制电力设备的选项。
由于一方面开关装置和另一方面用于开关装置的驱动器之间的隔离设置,开关装置可以通过与独立且可远程使用的电源一起被远程驱动的驱动器(远程驱动器)进行切换。
尤其是在医学领域的应用方面,关于电源供应系统的进一步要求被加在标准VDE0100-710中,这些要求超过了绝缘监测。因此,例如,在电压中断期间应当满足小于500ms的切换时间。
从现有技术中已知用于开关控制的远程驱动器,其基于作为致动器的电动机,但是不能满足所需的标准开关时间。此外,可以使用包括由电磁体控制的致动器的远程驱动器,但这些远程驱动器仅由一个控制电压源控制,因此不能确保所需的断电安全。此外,快速开关的远程驱动器也是已知的,其用弹簧制动器或电磁体来操作;然而,这些驱动器在机械上非常复杂,并且由于它们的尺寸,这些驱动器不适合安装在顶帽式轨道上。
发明内容
因此,本发明的目的是构造一种用于安装在顶帽式轨道上的开关装置的电力远程驱动器,该电力远程驱动器紧凑且构造简单,具有标准和快速的开关时间,并且可以由至少两个独立的能源供应能量。
该目的是通过根据权利要求1的特征的电力远程驱动器来实现的,该电力远程驱动器用于致动安装在顶帽式轨道上的电力设备的开关装置。
根据本发明的远程驱动器包括支撑元件,支撑元件被构造用于在顶帽式轨道上的标准安装。作为附加功能,远程驱动器因此能够直接与待驱动的开关装置相邻地安装。
两个实现为电磁体的相对的致动器被布置在支撑元件上,这两个致动器通过各自的杆形锚固件交替作用于可位移地安装的滑动件上。滑动件在其中心包括通道,用于接收摇臂杆的第一杆臂。摇臂杆绕着摇臂杆旋转轴是可枢转的,摇臂杆旋转轴平行于顶帽式轨道的长侧延伸,并且至少几乎穿过待致动的开关装置的换档杆的旋转点。在摇臂杆的第二杆臂上,平行于顶帽式轨道的长侧布置有承载轨道,开关装置的换档杆在第二杆臂的一侧接合到承载轨道中。当滑动件因电磁体被致动而位移时,摇臂杆翻转,由此开关装置的换档杆被同时致动。
由于两个单独可控的致动器是电位隔离的,因此可以从彼此独立的两个供电网络中为它们提供能量。此外,电磁体工作快速,因而能够缩短标准开关时间。电磁体优选地实现为牵引磁体。
关于另一个有利的实施例,承载轨道是U形的。
U形轮廓确保了足够的稳定性,承载轨道的抗扭刚度确保了力准确传递到换档杆。
此外,承载轨道以径向可位移的方式安装,以调整换档杆的移动。
为了保证远程驱动器与各种开关装置的可靠交互,承载轨道以径向可位移的方式安装,使得这种机械调整确保以尽可能小的游隙承载换档杆。
优选地,承载轨道具有足够的长度,以便能够致动在顶帽式轨道上彼此相邻安装的若干个开关装置。
因此,根据本发明的远程驱动器适于用来同时开关若干个在顶帽式轨道上彼此相邻布置的开关装置。
此外,支撑元件可以包括可拆卸的顶帽式轨道夹,以便更容易地安装顶帽式轨道。因此,例如,在45mm的保险开关内进行在标准顶帽式轨道上的快速安装是可能的。
利用根据本发明的权利要求6的远程驱动器组件,根据本发明的两个远程驱动器可以彼此相邻地布置在顶帽式轨道上并且设有锁定机构。通过在移动两个滑动件中的一个时锁定另一个滑动件,防止两个远程驱动器同时启动。
当使用根据本发明的两个远程驱动器和两个带有锁定机构的开关装置时,因此满足了这样的要求:根据标准IEC 60947-6-1,不应该允许两个电路互连以实现主开关。
特别是结合两个开关装置,根据本发明的远程驱动器组件被证明是可靠和紧凑的解决方案,其中,两个开关装置例如形成了用于交替地互连或断开或完全隔离两个电源网络的切换装置。
在锁定机构的另一个实施例中,与实现为滑动件的远程驱动器结合的锁定机构包括呈直角角形轮廓形状的锁定元件,该锁定元件可绕着与顶帽式轨道的平面成直角的锁定旋转轴旋转。当其中一个滑动件从断开(OFF)位置位移到接通(ON)位置时,该滑动件的前表面在该过程中撞击角形轮廓的侧表面,并且使该角形轮廓旋转,以至于另一个滑动件进入接通位置的移动通过角形轮廓的另一个侧表面抵靠该滑动件的前表面而阻止。
通过阻止相应的远程驱动器,可以确保远程驱动器不会同时打开相应的致动开关装置。
有利地,锁定机构可以构造为用于安装在顶帽式轨道上的独立结构单元,该结构单元由框架部件组成,用于被安装在顶帽式轨道上,具有锁定旋转轴的锁定元件被紧固至顶帽式轨道。
在本实施例中,锁定机构可以作为独立的结构单元集成到顶帽式轨道上的远程驱动器和开关单元的现有构造中。
可替换地,本发明的目的可通过根据本发明的电力远程驱动器来实现,该电力远程驱动器包括支撑元件,支撑元件被构造用于标准的顶帽式轨道安装,并且具有两个能够单独控制的致动器,每个致动器作为电磁体作用于T形摇臂开关的第一支腿和第二支腿上。在这种情况下,摇臂开关包括在旋转点处与第一支腿和第二支腿形成直角的第三支腿,在第三支腿的端部上平行顶帽式轨道的长侧安装有承载轨道,开关装置的换挡杆在第三支腿的一侧接合到承载轨道中,摇臂杆绕着摇臂杆旋转轴可枢转,旋转轴平行于顶帽式轨道的长侧延伸并穿过换档杆的旋转点。
可替换开头描述的解决方案(其中两个相对的电磁体作用于可位移地安装的滑动件上)的是,本实例中描述的实施例基于两个电磁体,每个电磁体作用于摇臂开关的一端,从而经由在摇臂开关的中心形成的第三支腿来致动换档杆。
进一步有利的实施例特征由下面的描述和附图中得出,附图用示例描述了本发明优选的实施例。
附图说明
在附图中:

图2a、2b、2c是具有用于类型滑动件的锁定机构且根据本发明的远程驱动器组件的功能示意图;
图3是根据本发明的远程驱动器的第二实施例(类型为摇臂开关)的示意图。
具体实施方式
图1是根据本发明的远程驱动器2的第一实施例(类型为滑动件)的示意图。两个相对的致动器10a、10b布置在支撑元件8上,支撑元件8紧固至顶帽式轨道6(能够经由顶帽式轨道夹7安装),致动器10a、10b作为牵引磁体通过它们的杆形锚固件交替地作用于可位移地安装的滑动件12上。
滑动件12包括通道14,摇臂杆18的第一杆臂16a穿过该通道14。摇臂杆18安装在摇臂杆旋转轴24中,该摇臂杆旋转轴轴平行于顶帽式轨道6的长侧定向,其旋转点几乎与开关装置4的换档杆22的旋转点完全重合。在摇臂杆18的第二杆臂16b的端部,承载轨道20与顶帽式轨道6的长侧平行布置。开关装置4的换档杆22接合到承载轨道20中,并且在枢转摇臂杆18时被致动。
在图2a、2b、2c中,根据本发明的远程驱动器组件的功能被示意性示出,该远程驱动器组件具有两个相邻的远程驱动器2和锁定机构40。锁定机构40包括在远程驱动器2的滑动件12之间的锁定元件42,锁定元件42被实现为直角等腰角形轮廓42,例如实现为三角形杆截面,并且被安装为绕着锁定旋转轴44可旋转。
从图2a中两个滑动件12的断开(OFF)位置开始,当滑动件12中的一个被移动到接通(ON)位置时,该滑动件的前表面13撞击锁定机构42的侧表面42a。由此,锁定元件42旋转并且通过其另一侧表面42b阻止另一滑动件12的向下移动(用于接通的移动)(图2b、2c)。
在图3中,示出了根据本发明的远程驱动器2的第二实施例(类型为摇臂开关)。在本实施例中,电磁体62a和62b分别作用于摇臂开关66的第一支腿64a和第二支腿64b。摇臂开关66包括在中心与第一支腿64a和第二支腿64b形成直角的第三支腿64c;被紧固在第三支腿64c的一端的承载轨道20;以及接合到承载轨道20中的开关装置4的换档杆22。摇臂开关旋转轴68平行于顶帽式轨道6的长侧延伸,旋转点几乎位于换档杆22的旋转点。
