Description

旋转式双断点开关接触系统接线改良结构 技术领域
本发明属于隔离开关技术领域,,具体讲就是涉及一种旋转式双断点开关接触系统接线改良结构。
背景技术
隔离开关是高压开关电器中使用最多的一种电器，隔离开关的主要特点是无灭弧能力，只能在没有负荷电流的情况下分、合电路。隔离开关用于各级电压，用作改变电路连接或使线路或设备与电源隔离，它没有断流能力，只能先用其它设备将线路断开后再操作。一般带有防止开关带负荷时误操作的联锁装置，有时需要销子来防止在大的故障的磁力作用下断开开关。在电路系统中，当线路出现故障或者需要检修时，断路器跳闸，此时隔离开关起到了切断小电流或者提供明显端口的作用，以保障维修或者检修时工作人员的安全。通常情况下，隔离开关有两种形式，敞开式和气体绝缘金属封闭式，敞开式隔离开关直接暴露在空气中，分闸时可看到明显断口，但体积大、较为笨重。气体绝缘金属封闭式隔离开关体积小、可靠性高，得到了广泛应用，气体绝缘金属封闭式隔离开关一搬包括三个隔离开关单相，每个隔离开关单相均包括筒体，各筒体中均设置有动触头、静触头和驱动动触头动作的驱动机构，驱动机构大多数采用电驱动，然而由于气体绝缘金属封闭式隔离开关的封闭性，操作人员不能直接观察和明显感受其是否处于分断状态。
目前市场上有一种常见的旋转式双断点隔离开关，其接触系统的接线只能采取一个方向进线的方式进行，缩小了旋转式双断点隔离开关的适用范围，在 某些特殊场合需要改变隔离开关的安装位置时，无法调整接线方向，导致隔离开关无法适用。
发明内容
本发明的目的是针对现有的旋转式双断点隔离开关接线方向单一的技术缺陷，提供一种旋转式双断点开关接触系统接线改良结构，通过对接线方式的改进使旋转式双断点隔离开关接触系统的接线方向能够灵活改变，满足了隔离开关现场安装的需要。
技术方案

进一步，所述接线螺钉的安装轴线方向与所述动触头中心轴线垂直。
进一步，所述短接排为
Figure PCTCN2017071545-appb-000001
形状，其两端分别设有接线螺钉安装过孔，通过所述接线螺钉与所述静触头的尾端锁在一起，所述静触头的头端伸进所述动触头的槽中，所述动触头在转动过程中其触头端能够与静触头的所述头端接触形成电连接。
进一步，所述静触头的所述尾端设有螺纹孔，所述静触头的头端和尾端通过一连接部连接在一起。
更进一步，所述静触头的所述头端和所述尾端是相互垂直的平面状结构。
进一步，所述动触头转动过程中能够与所述静触头的所述头端接触实现双断点。
进一步，所述动触头装在联轴器上。
进一步，所述动触头、静触头和短接排装在基座上。
进一步，所述接线螺钉与所述静触头连接的接线口的底面向下倾斜，这样，增大了插入所述接线螺钉与所述静触头之间的连接线的接线角度。
有益效果
本发明提供一种旋转式双断点开关接触系统接线改良结构，通过对接线方式的改进，也就是，所述静触头通过一接线螺钉与所述短接排相连接，使得所述接线螺钉能够沿周向进线，这样使旋转式双断点隔离开关接触系统的接线方向能够灵活改变，满足了隔离开关现场安装的需要。

形状，其两端分别是平面状的结构，且相互平行，中间通过一杆或板结构相连，每一端都设有接线螺钉安装过孔301，其一端通过接线螺钉4与静触头2的尾端203锁在一起，可用来外接线(再参见附图2和6)，另一端305伸入基座6的连接槽8中，可以与另外一个根据需要时组合使用的旋转式双断点开关方便联通(电气连接)。静触头2的头端202伸进动触头1的槽101中，槽101的平面与动触头1中心轴线垂直，这样，动触头1转动过程中触头端102能够与静触头2的头端202接触形成电连接。在本实施例中，上述安装孔301是一缺口，方便连接，当然也可以采取封闭的孔。
再参见图1，接线螺钉4与静触头2连接的接线口9的底面91向下(向基座的底面)倾斜，这样，插入接线螺钉4与静触头2之间的连接线就可以实现0°-45°左右的不同的接线角度，增大了接线角度，方便接线。而现有的开关的高底面几乎与基座6的表面平行，只能一个方向接线。
如附图6所示，静触头2的尾端设有螺纹孔201，静触头2的头端202和尾端203通过连接部204连接在一起。在本实施例中，通过连接部204的过渡，使得静触头2的平面状的头端202和尾端203的平面相互垂直，使得接线螺钉4能够沿周向进线。
再参见附图5，动触头1在转动过程中能够与2个静触头2的头端202接触实现双断点(请解释一下“双断点”的含义，如果是行业中规范的名词，可以不需要解释)。
动触头1装在联轴器5上。
本发明提供的一种旋转式双断点开关接触系统接线改良结构，通过对接线方式的改进，静触头2通过接线螺钉4与短接排3相连接，使得接线螺钉4能够沿周向进线，这样使旋转式双断点隔离开关接触系统的接线方向能够灵活改变，从而满足了本发明的隔离开关在现场安装的各种位置的要求。
