背景技术
传统三线PE可断开型漏电保护器已实现了供电插座E(地线)带电后立即切断负载供电，实现了“地线异常带电”的跳闸保护功能。而漏电保护器是机械与电子的结合体，要实现漏电保护功能的有效前提是:漏电保护器应有正常供电的电压。而设置有漏电保护器的产品在实际运用中有相当多的用户采用插座上的开关去切断漏电保护器的供电电源，此操作最大的安全隐患是:当地线异常时，会使带电的漏保器将无法提供跳闸安全保护，从市场反馈的信息可以看出，因人为关闭供给漏保器插座的电源开关是引发人身安全事故的主要原因，为了解决及类似安全隐患。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一：如图1-图9所示，一种设置有自动供电和断电功能的漏电保护器，主要由壳体1和均位于壳体1内部的插脚座2、插脚3、弹片4以及自锁装置5组成。所述插脚3与弹片4均安装在插脚座2上并分别设置有可相互接触的插脚触点101和弹片触点102，接触后即可实现接触通电，其中所述弹片触点102位于插脚3的上方，并通过弹片4的弹性结构使其触点自动向上复位，即可实现分离断电。
如图2-图10所示，所述自锁装置5包含有驱动机构51、横档块6、设置有复位继电器71的复位座7以及自锁杆9。所述驱动机构51包括维持脱扣座52、与维持脱扣座52的解锁杆54和维持脱扣座52内的维持脱扣继电器53。所述复位座7和维持脱扣座52均均安装在插脚座2的顶部，所述横档块设置在复位座7和维持脱扣座52之间，所述自锁杆9与维持脱扣座52铰接并通过第二复位机构93(结构为扭簧)使其逆时针旋转复位，所述横档块6与插脚座2铰接并通过第一复位机构64(结构为扭簧)使其顺指针旋转复位。所 述第一复位机构64和第二复位机构93的结构具体可以为扭簧结构。
上述的自锁杆9一端与解锁杆54接触，另一端设置有一个有内凹的锁紧缺口91和解锁缺口92；所述锁紧缺口91用于与锁紧端62卡接以固定横档块6自锁杆9旋转角度。
如图9所示，上述的横档块6的两端包含有下压端61和锁紧端62，中间处设置有一个连接孔63，所述自锁杆9设置有内凹的锁紧缺口91；
如图2和图9所示，上述的复位继电器71和维持脱扣继电器53分别设置有一个横向直线移动的推杆10、20，所述复位继电器71的推杆10与连接孔63连接，所述复位继电器71在通电后可以控制推杆10朝复位继电器71的内部移动以使横档块6实现逆时针旋转；所述横档块6的下压端61被带动旋转后下压弹片4，使弹片触点102与插脚触点101接触以实现通电，而横档块6的锁紧端62卡接到锁紧缺口91内也可以限制横档块6旋转，故使下压端61无法移动。
上述的维持脱扣继电器53还包含在一个第三复位机构56(结构为压簧)和一个通电状态下对推杆20进行吸合的吸合杆55，所述吸合杆55位于维持脱扣继电器53的内部，所述推杆20通过吸合杆55的吸力可向维持脱扣继电器53的内部移动并与吸合杆55吸合。所述吸合杆55的吸力会大于第三复位机构56的复位压力且力的方向相反，所以在外部电源断电情况下，吸合杆55失去吸力，所述第三复位机构56便通过其压力使维持脱扣继电器53的推杆20始终向解锁杆54方向移动，故可带动解锁杆54实现逆时针旋转，而解锁杆54带动所述自锁杆9实现顺时针。即可使自锁杆9的锁紧缺口91脱离锁紧端62使横档块6可以正常活动，即可解除对其限制，故所述弹片触点便可与插脚触点分离以实现断电。
上述的第三复位机构56的复位压力大于第二复位机构93的复位压力，如此才能控制自锁杆9实现顺时针旋转。
如图10所示，上述的解锁缺口92的边沿设置有一个与锁紧端62接触的连板94，因为上述的第三复位机构56的复位压力大于第二复位机构93的复位压力，所以通过该连板94可以使第一复位机构64的压力与第二复位机构93的压力结合而大于第三复位机构56的复位压力因此可以使维持脱扣继电器53的推杆20内移。
本实施例设置有一个控制上述部件工作的压驱动模块Ⅰ。
操作过程：当外部的电源断电后，所述压驱动模块Ⅰ会使维持脱扣继电器53断电而使吸合杆55失去吸力，而维持脱扣继电器53的推杆20在第三复位机构56的压力外移并带动解锁杆54逆时针旋转，所述解锁杆54通过与自锁杆9的位置配合使锁紧缺口91顺时针旋转，故锁紧缺口91脱离锁紧端62,从而实现解锁，所述锁紧端62在通过第一复位机构64的作用下顺时针移动使下压端旋转上移并与弹片4分离，弹片4即可通过自身向上复位的弹力使弹片触点102与插脚触点101，而自锁杆9在第二复位机构93的作用下带动解锁缺口92逆时针移动(参考图20)。在上述操作中，活动状态的锁紧端62会与活动状态的解锁缺口92卡接从而固定自锁杆9旋转角度(图2、图3、图5、图7和图9所示)，从而实现解锁断电，此时解锁断电后，通过横档块6和自锁杆9各自的复位压力使自锁杆9逆时针旋转，而自锁杆9带动解锁杆54顺时针旋转使推杆20内移到维持脱扣继电器53内并与吸合杆55接近或者接触(如图3、图5和图7)。
当外部的电源恢复供电后，如图20所示，通过一个电压驱动模块Ⅰ使所述复位继电器71通电后控制其推杆10内移，所述推杆10控制横档块6相对于插脚座2顺指针旋转， 即下压端61向下旋转并下压弹片4使压弹片触点102与插脚触点101接触，与此同时所述锁紧端62也逆时针旋转并带动自锁杆9逆时针旋转移动的角度，当锁紧端62脱离解锁缺口92后，此时所述自锁杆9无压力阻碍并可通过其第二复位机构9逆时针旋转，即可使锁紧端62进入到锁紧缺口91内并定位卡接，故可以限制了横档块6旋转，因此所述横档块6的下压端61始终下压压弹片4从而两者的触点接触(如图2、图4、图6和图8)，同时，通过一个电压驱动模块Ⅰ使所述维持脱扣继电器53通电后使吸合杆55产生吸力使维持脱扣继电器53内的推杆20内从而完成自锁状态，以实现自动上电。
如图11所示，为了显示上电或者断电的信号，并根据国家的安全标准，本发明还包括一个套接在自锁杆9上并均相对维持脱扣座52同轴旋转的状态指示座8和一个位于壳体顶部的透明显示块11，所述状态指示座8顶部和底部分别设置有一个指示块81和档杆82；所述透明显示块11位于指示块81的顶部，所述锁紧端62与档杆配合82接触；
在断电过程中，所述横档块6会通过第一复位机构64顺时针旋转将弹片触点102与插脚触点101分离的同时会下压档杆使指示块81逆时针旋转并离开透明显示块11的正下方，从而以显示断电完成的信号；
在上电过程中，所述横档块6逆时针旋转将弹片触点102与插脚触点101接触的同时脱离档杆82，所述指示块81便通过一个第六复位机构83顺时针复位旋转到透明显示块11的正下方，从而以显示上电完成的信号。
图2-图9所示，上述的插脚3的数量有3个，并分别为地线插脚、火线插脚和零线插脚，具体的说，中间的插脚3为地线插脚，其他两个分别为火线插脚和零线插脚。所述弹片4的数量有3个，并分别为地线弹片、火线弹片和零线弹片，具体的说，中间的弹片4为地线弹片，其他两个分别为火线弹片和零线弹片。而所述横档块6的下压端61有3个，并分别位于上述3个弹片4的顶部，其中位于地线弹片顶部的下压端61的位置低于其他两个下压端61，
在弹片4下压的时候，位于地线弹片顶部的下压端61会先接触地线弹片4，使地线弹片4的弹片触点与地线插脚的插脚触点先接触，然后再是火线弹片4的弹片触点与火线插脚的插脚触点接触与零线弹片4的弹片触点与零线插脚的插脚触点接触，故在恢复供电的过程中，地线先接触连接，零火线再接触连接。
在弹片4复位上移的的时候，火线弹片4的弹片触点与火线插脚的插脚触点先分离，零线弹片4的弹片触点与零线插脚的插脚触点也同时分离，然后再是地线弹片4的弹片触点与地线插脚的插脚触点分离，故在断电工作中，零火线先分离，地线再分离。
故通过上述两种工作状态，使此结构符合国家安全的标准规范。
因此采用这样机械机构的信号系统，相比采用电控制的信号系统使用更安全。
实施例二：如图12-图19和图21所示，本实施二的技术方案与实施例一的结构和功能基本相同，不同点包含以下几点。
1、在实施例一的基础上去除了一个使横档块6顺时针旋转的第一复位机构64，并在所述复位继电器71设置有一个第四复位机构72，所述第四复位机构72通过其压力使复位继电器71的推杆10始终向复位继电器71的外侧移动，因为复位继电器71的推杆10可以控制横档块6旋转，所以通过第四复位机构72进一步的可以控制横档块6顺指针旋转(如图15和图16)；
2、在上述基础上去除了一个吸合杆，而且维持脱扣继电器53在通电后可以使维持脱扣继电器53的推杆10向解锁杆54方向移动。其作用是使为了通电后带动解锁杆54旋转，而且该结构设置了一个使维持脱扣继电器53的推杆10始终向维持脱扣继电器53的内部的第五复位机构57(结构为压簧)，其作用是为了断电后实现推杆10的复位(如图15和图16)。
3、在上述基础上去除了所述自锁杆9下部的连板94，因为通过第五复位机构57可以使维持脱扣继电器53的推杆自动内移，所以无需设置连板94(如图19)。
操作过程也基本与实施例一的方式相同：所不同的是本实施例去除了电压释放模块Ⅰ，并设置有一个电压释放模块Ⅱ。当外部的供电电源中断后,所述电压释放模块Ⅱ设置有一个储能电路，通过电压释放模块Ⅱ上的储能电路释放电压使所述维持脱扣继电器53通电以控制其推杆向解锁杆54方向移动并带动其顺时针旋转，所述锁紧缺口91便与锁紧端62分离，在第四复位机构72的作用下，所述复位继电器71内的推杆10控制横档块6旋转并脱离弹片4，所述弹片4通过自身压力向上移动使弹片触点102与插脚触点101分离而完成解锁断电(如图21)；当电压释放模块的电力释放完后，所述维持脱扣继电器53断电后无法驱动其推杆10一直朝向解锁杆54方向移动，并在第五复位机构57的压力下内移，从而在第二复位机构93的压力使自锁杆9逆时针旋转将解锁缺口92压在锁紧端62上(图13、图15和图17)。
当恢复供电后，通过电压释放模块Ⅱ使所述复位继电器71通电后控制其推杆向内移动，从而带动横档块6逆时针旋转，下压端61下压弹片4使弹片触点102与插脚触点101接触通电，所述锁紧端62脱离解锁缺口92并卡在锁紧缺口91内(如图21)，在第二复位机构93的作用使锁紧缺口91逆时针旋转从而与锁紧端62固定卡接形成锁定状态(图14、图16和图18)。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
