此外,下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
本发明实施例提供的一种具有定时功能带自检的漏电保护器,包括:直流电源供电模块1、直流电源供电模块控制开关2、漏电保护模块3、定时器模块4、其中,直流电源供电模块1用于将交流电转换为直流电源,给漏电保护模块3和定时器模块4供电;漏电保护模块3与定时器模块4共用直流电源供电模块(如图1所示),或漏电保护模块与定时器模块各自连接独立的直流电源供电模块供电(如图2所示),当漏电保护模块3与定时器模块4共用直流电源供电模块时,直流电源供电模块控制开关2连接于直流电源供电模块和漏电保护模块开关之间(如图1所示),漏电保护模块与定时器模块各自连接独立的直流电源供电模块供电时,直流电源供电模块控制开关2连接于输入交流电与给漏电保护模块供电的直流电源供电模块之间(如图2所示),在待机情况下直流电源供电模块控制开关2处于断开状态;根据定时功能要求,定时器模块4发送断开或接通直流电源供电模块控制开关2的信号,当定时器模块4发送接通直流电源供电模块控制开关的信号时,直流电源供电模块控制开关2闭合,使漏电保护模块3接通电源进行上电复位,紧接着进行漏电功能自检,自检通过则向负载供电,且在每次向负载进行供电前均进行自检。
本实施例中的直流电源供电模块1包括:依次连接的降压回路、整流电路、滤波稳压电路,其中降压回路将交流电进行降压后,通过整流电路转换为直流电源,然后经过滤波稳压电路输出平滑的直流电。

在一具体实施例中,如图3所示,漏电保护器位于AC电源输入和AC电源输出之间,其漏电保护保护模块包括脱扣器,互感器ZCT及漏电保护电路,定时器模块包括定时器电路和带位置指示的开关,定时器模块和漏电保护模块共用一个直流供电源(DC电源供电),定时器模块通过发送信号来控制直流电源供电模块控制开关(DC电源供电控制开关)的通断,进而控制漏电保护器工作,进行漏电检测后为负载提供电源(AC电源输出)。
如图4所示的为图3对应漏电保护器定时器模块部分的电路原理图,本实施例中的漏电保护器模块GFCI可以实现自检功能,其具体电路为现有技术中的可以实现自检的漏电保护电路,例如专利CN211629848U的电路结构,在此不再赘述。直流电源供电模块控制开关Q1可以为继电器或半导体器件(如MOSFET、BJT、SCR),直流电源供电模块中的降压回路包括:降压电容C1,电阻R1、R2为电容C1提供放电回路;整流电路为D1-D4桥式整流电路;滤波稳压电路包括:滤波电容C2、稳压器Z1、分压电阻R3、R4,二次滤波电容C3,U2为稳压IC,及稳压后的低频滤波电容C4,高频滤波电容C5;定时器主控电路U1为MCU,pin1为电源,Pin8电源接地,Pin2-7均为I/O端口,二极管D5、电阻R5、稳压器Z2、电阻R6、电容C6组成交流过零检测电路,为MCU提供时基校准。
本发明实施例中带定时位置指示的开关S2为带时间刻度的选择开关,其可以取消时间指示电路,降低成本,同时降低了定时模块的待机功耗。定时时间通过旋钮开关调节(一档长通,二挡停止,三档定时时间2小时延时20分;四挡定时时间为4小时延时20分;五挡定时时间为6小时延时20分;六挡定时时间为8小时延时20分;七档定时时间为12小时延时20分)。中途换档后,定时器重新计时;定时器24小时后重新开机定时(定时器24小时为一循环周期),以上旋转开关各个档位对应的定时时间仅作为举例,不以此为限。
另一具体实施例漏电器的组成如图5所示,与图3所示的漏电保护器不同的是,定时器模块包括定时器电路和选择开关和显示电路,漏电保护模块与定时器模块各自连接独立的直流电源供电模块供电(DC电源供电),定时器模块通过发送信号来控制直流电源供电模块控制开关(DC电源供电控制开关)的通断,进而控制漏电保护器模块工作。
如图6所示的为图5对应漏电保护器的电路原理图,其与图4不同的是,定时器模块选择开关S1为按压触发按钮,通过按压选择开关S1来触发定时器;显示电路为包括三个LED指示灯(LED1、LED2、LED3),指示灯的点亮数量用来指示定时时间,实际应用中可以设置为LED1长亮定时2个小时,闪烁定时4个小时,熄灭代表定时完成、LED2长亮定时6个小时,闪烁定时8个小时,熄灭代表定时完成、LED3长亮定时10个小时,闪烁定时12个小时,熄灭代表定时完成、全部熄灭时代表直流电源供电模块控制开关断开。需要说明的是显示电路的设置形式只是作为举例说明,并不以此为限。
