Description

一种框架一体式双电源 技术领域
本发明属于低压电器元器件设备技术领域，具体涉及一种用于保护电路并自动转换的双电源开关。
背景技术
配电电器中，双电源开关用于保护线路及设备免受过载、短路等故障危害的同时，更可以快速的自动切换另一路备用电源，保证线路的持续供电。随着重用场所的越来越广，设备等用电量的越来越大，其对大容量双电源开关的需求越来越大。
目前市场上的大容量双电源主要是由两台框架断路器联接起来使用，其体积大，成本高，无法满足一些重用场所的需求。
中国专利申请201210050095.9公开了一种用于双电源转换开关的联锁装置，包括切换机构、操作机构、指示机构和联锁机构；切换机构包括切换主轴和换向板，换向板的边缘处设有滑面；操作机构中设有框架和合闸半轴；指示机构包括主指示件、主复位弹簧、副复位弹簧；联锁机构包括联锁板、主联锁杆和副联锁杆；联锁板的基本形状是设有三个凸板的Y形，其中心转动设置在操作机构的框架上；联锁板中各凸板上均设有一个联锁孔，其中一个凸板通过其联锁孔套设在合闸半轴上，另两个凸板通过其联锁孔与主联锁杆或副联锁杆相连；主联锁杆的另一端与主指示件相连，副联锁杆与副指示件相连。该发明能够根据切换主轴所处状态，通过指示机构的联动进而限位合闸半轴，有效防止因误操作的发生，提高了安全性能。但是该发明结构相对复杂，操作相对不便，转换电源的可靠程度也有些不足，无法满足一些重用场所的需求。
发明内容
本发明目的是：针对现有技术中难以在重用场所进行大电流的供电自动转换的问题，提供一种框架一体式双电源，其供电由两路电源进行，当常用电源 断电或故障时，帮助其快速切断并转换至另一路电源。
具体地说，本发明是采用以下技术方案实现的：
一种框架一体式双电源，包括转换机构、操作机构以及两组触头组件，所述触头组件包括动触头和静触头，两个动触头通过连接轴相互连接，连接轴上设置有转轴，两个动触头可以以所述转轴为中心转动，所述转换机构的一端设置有两个分支，分别与动触头相连，另一端通过手柄的拨动对合闸的方向进行预选，操作机构通过对转换机构的推动实现转换机构对预选的合闸方向的静触头的推动，使这一端的触头组件合闸。
进一步地，所述转换机构包括手柄和转盘，所述手柄和转盘之间通过第一连杆机构联动，所述转盘和一个动触头之间通过第二连杆机构联动，所述转盘和另一个动触头之间通过第三连杆机构联动。
进一步地，所述第一连杆机构包括第一连杆和转动板，所述转盘上设置有第一腰型孔，第一连杆的一端通过腰型孔限位，另一端与转动板铰接，第一连杆的中部活动套设于转轴上，转动板的转动由手柄驱动。
进一步地，所述第二连杆机构包括第二连杆、第三悬臂和第二主轴，所述转盘上设置有第二腰型孔，第二连杆的一端限位于第二腰型孔，另一端与第三悬臂的一端铰接，第三悬臂的另一端固定于第二主轴上，第二主轴上还固定有连杆，连杆与静触头相连，并根据第二主轴的旋转而推动或拉动静触头，所述第三悬臂上还连接有用于拉伸储能的弹性部件；所述第三连杆机构的结构与第二连杆机构相同。
进一步地，所述操作机构包括第一主轴、第二悬臂和滑块，所述第二悬臂的一端固定于第一主轴上，另一端与滑块铰接，用于支撑所述转动板转动的转轴设置于滑块上。
进一步地，当与主回路合闸时，对应的弹性部件拉伸以储存能量，分闸时弹性部件中的能量释放。
进一步地，所述转盘上的所述第二腰型孔沿转盘的圆周方向弯曲。
进一步地，所述转动板呈等腰三角形，且其顶点与第一连杆相连，底边与手柄的底部相抵接。
进一步地，所述转动板的顶点设置有腰型孔，所述第一连杆的端部限位于所述腰型孔中运动。
进一步地，所述本体的上半部分设置第一组触头组件，为上主回路，该部分合闸时接通主电源，本体的下半部分设置另一组触头组件，为下主回路，该部分合闸时接通备用电源。
本发明的有益效果如下：
本发明允许两路电源同时断开，但仅允许一路电源接通。由于本发明仅有一个操作机构，当一路电源在接通状态，另一路电源是无法合闸接通电源的，所以本发明可靠的保障了主回路的安全；本发明利用了框架短路器的大容量额定电流及分断指标和一体本体加一台机构的结构特征，降低了产品空间及成本。

具体实施方式
下面结合实施例并参照附图对本发明作进一步详细描述。
实施例1：
本发明具体实施例的框架一体式双电源结构示意图参见图1，本发明主要由本体、转换机构、操作机构等组成，其中本体包括后基座1、前基座2、第一静触头31、第一动触头32、动触头母排33、第二动触头34和第二静触头35，从图1的视角来看，本体的上半部分为上主回路(或者第一主回路)，与其连接后可接通主电源，本体的下半部分为下主回路(或者第二主回路)，与其接通后可接通备用电源；转换机构包括手柄15、第五轴16、转动板17、第六轴18、第七轴19、第八轴20和转盘28；操作机构包括操作部件8、第一主轴9、第二悬臂10、滑块12、第二主轴26和第三主轴30。这三大组成部分之间主要通过连杆或者拉簧等零部件进行连接和传动。
本发明可以允许两路电源同时断开，即两分状态，参见图2和图4；但是不允许两路电源同时接通，在同一时间内只能接通一路电源，参见图3上触头合闸状态或者图5下触头合闸状态。
参见图2，当两路主回路的电源断开时，转换机构可以转换准备合闸的方向，即合闸上主回路(第一主回路)还是下主回路(第二主回路)，当逆时针(以图2的视角为准)转动手柄15时，手柄15推动三角形的转动板17的底边绕第四轴14逆时针转动，转动板17逆时针转动通过第六轴18带动与转动板17的顶点相连接的第一连杆13绕第七轴19顺时针(以图2的视角为准)转动，第一连杆13顺时针转动则带动第八轴20处于转盘28的第三腰型孔38的上方，即进入图2所示的准备合闸上主回路(第一主回路)的状态。
参见图3，当操作机构合闸上主回路(第一主回路)时，操作机构第一主轴9顺时针转动(以图3视角为准)，同时带动第二悬臂10绕第一主轴9顺时针转动，第二悬臂10顺时针转动则通过第三轴11带动滑块12向左滑动，滑块12向左滑动的同时通过第七轴19带动第一连杆13向左移动。由于转盘28只能转 动，第一连杆13向左滑动则会通过第八轴20推动转盘28逆时针转动。第三主轴30与第一悬臂3固定，第一悬臂3通过第一轴6、第三连杆29、第二轴7与转盘28连接，转盘28逆时针转动，则会通过第一轴6、第三连杆29、第二轴7拉动第一悬臂3顺时针转动，第三主轴30也会顺时针转动，此时第三连杆29上的第二轴7位于转盘28上的第一腰型孔36的靠近第三腰型孔38一端，第二连杆25上的第十轴27位于转盘28上的第二腰型孔37的远离第三腰型孔38一端，同时将第一拉簧5拉到储能状态。第三主轴30顺时针转动可以推动第二动触头34与第二静触头35闭合，即接通上主回路(第一主回路)。
参见图2，如果想接通下主回路(第二主回路)，则必须先断开上主回路(第一主回路)。当操作机构分闸时，第一主轴9带动第二悬臂10逆时针转动，第二悬臂10通过第三轴11带动滑块12向右滑动，滑块12向右滑动则通过第七轴19带动第一连杆13、第八轴20向右移动，由于转盘28没有第八轴20的推力，则转盘可以顺时针转动，接通上主回路(第一主回路)时，第一拉簧5的能量已储存，此时第一拉簧5则拉动第一悬臂3和第三主轴30逆时针转动，第一悬臂3逆时针转动通过第一轴6、第三连杆29、第二轴7拉动转盘28顺时针转动，第二轴7位于第一腰型孔36靠近第三腰型孔38的一端；第三主轴30逆时针转动则可以带动第二动触头34与第二静触头35分离，即切断上主回路(第一主回路)。
参见图4，当顺时针转动手柄15时，手柄15推动转动板17绕第四轴14顺时针转动，转动板17顺时针转动通过第六轴18带动第一连杆13绕第七轴19逆时针转动，第一连杆13逆时针转动则带动第八轴20处于转盘28的第三腰型孔38的下方，则进入图4所示的准备合闸下主回路(第二主回路)的状态。
参见图5，当操作机构合闸下主回路(第二主回路)时，第一主轴9顺时针转动，同时带动第二悬臂10绕第一主轴9顺时针转动，第二悬臂10顺时针转动则通过第三轴11带动滑块12向左滑动，滑块12向左滑动的同时通过第七轴19带动第一连杆13向左移动，由于转盘28只能转动，第一连杆13向左滑动则会通过第八轴20推动转盘28顺时针转动，第二主轴26与第三悬臂23固定，第三悬臂23通过第九轴24、第二连杆25、第十轴27与转盘28连接，转盘28顺时针转动，则会通过第九轴24、第二连杆25、第十轴27拉动第三悬臂23逆时针转动，第二主轴26也会逆时针转动，此时第三连杆29上的第二轴7位于转盘28上的第一腰型孔36的远离第三腰型孔38的一端，第二连杆25上的第十轴27位于转盘28上的第二腰型孔37的靠近第三腰型孔38的一端，将第二拉簧21拉到储能状态，第二主轴26逆时针转动可以推动第一动触头32与第一静触头31闭合，即接通下主回路(第二主回路)。
参见图4，当操作机构分闸时，第一主轴9带动第二悬臂10逆时针转动，第二悬臂10通过第三轴11带动滑块12向右滑动，滑块12向右滑动则通过第七轴19带动第一连杆13、第八轴20向右移动，由于转盘28没有第八轴20的推力，转盘28可以逆时针转动，接通下主回路(第二主回路)时，第二拉簧21的能量已储存，此时第二拉簧21则拉动第三悬臂23和第二主轴26顺时针转动，第三悬臂23顺时针转动通过第九轴24、第二连杆25、第十轴27拉动转盘28逆时针转动，第十轴27位于第二腰型孔37的靠近第三腰型孔38的一端；第二主轴26顺时针转动则可以带动第一动触头32与第一静触头31分离，即切断下主回路(第二主回路)。
虽然本发明已以较佳实施例公开如上，但实施例并不是用来限定本发明的。 在不脱离本发明之精神和范围内，所做的任何等效变化或润饰，同样属于本发明之保护范围。因此本发明的保护范围应当以本申请的权利要求所界定的内容为标准。
