Abstract

地控磁座防合墙属输配电工程技术领域。硬塑料墙一端嵌有磁铁,另一端有绳钩,中有杆洞。绳钩拴上绝缘绳拉住,绝缘杆挑起,利用磁铁吸力,可以吸在拉开的隔离天关的刀根触点与刀头触点之间的开关座上,防止误会。用于配电线路的检修工作。

Description

地控磁座防合墙
技术领域输配电工程。
背景技术隔离开关一类的线路切断设备,现在在刀闸切断后,没有强制性的防误合装置。多年的生产实践中不乏误合事故。这类设备需要一种强制性的防误合装置。
发明内容隔离开关(附图)断开后,在槽钢做的开关座C上闸刀G的刀根触点A与刀头触点D之间放置一堵地控磁座防合墙,不取掉防合墙不能合上闸刀G,可以防止开关误合。地控磁座防合墙墙体1是塑料做的斧形墙,墙体1的斧把段中有杆洞3,可以插入电工绝缘杆F;斧头段的一端嵌有磁铁2;另一端是绳钩4,可以钩挂绝缘绳E。
使用时,①工人站于地面,用适长的绝缘杆F拉开闸刀G,②绳钩4上挂一绝缘绳E。③把绝缘杆F插入杆洞3。④拉紧绝缘绳E并握住绝缘杆F,把墙体1贴着刀根触点A挑向开关座C,墙体1被磁铁2吸附在开关座C紧靠刀根触点A处的刀根触点A与刀头触点D之间。即使因某种外力扬起闸刀G,因墙体1的居中阻挡也合不上开关。⑤用绝缘杆F把绝缘绝E挑下。或者把绝缘绳E挽起悬空,超过人体高度,使站地人员不能触及。⑥进行检修作业。⑦作业毕,在绳钩4上,用绝缘杆F挂上绝缘绳E,或解开挽起的绝缘绳E。再把绝缘杆F插入杆洞3。一手握住绝缘杆F,一手拉动绝缘绳E,墙体1绕端线B转动。因绝缘绳E的力臂远大于磁铁2的重臂,故墙体1很易克服磁铁2的吸力被拉起取下。
地控磁座防合墙的优点是:①挡在刀根触点A与刀头触点D间,可靠地防止闸刀G上扬接合。②站在地面装取,方便。③重量轻,便操作。
附图说明附图示地控磁座防合墙结构示意图。
具体实施方式墙体1硬塑料注塑而成;宽度略大于开关座C的宽度K,使绳钩4超出开关座C;高度等于刀根触点A的高度,即使闸刀G误返接合位,也不能与刀头触点D闭合。杆洞3直径等于绝缘杆F的外径,二者动配合;深度2倍绝缘杆F外径。洞口有导入倒角。强磁材料做的磁铁2呈圆柱形,紧紧嵌于塑料墙体1内,外端面较墙体1表面略高。
