Description

用于剩余电流操作的断路器的自动重置装置
技术领域
本发明涉及一种特别应用于剩余电流操作的断路器等的自动重置装置。更具体而言，本发明涉及一种装置，当剩余电流操作的断路器释放以后，其在检查系统的正确操作后允许自动重置一个剩余电流操作的断路器。
背景技术
众所周知，剩余电流操作的断路器通常在家庭和工业系统中提供，以防止一个错误的电流对使用者和连接到电线上的负载造成危险。
本质上，该剩余电流操作的断路器，在它检测到错误电流时，中断线路，从而中断了设置在下游的一个或多个负载的电源供给。
在剩余电流操作的断路器释放以后，一旦系统的正确的操作条件恢复以后，剩余电流操作的断路器必须被重置。
由于错误是一种由过压产生的暂时性错误，该操作条件通常可以自己自动恢复。
该重置通常是通过操作一个适当地提供的重置控制杆来手动的发生。
然而，如果使用者在打开了或者释放了剩余电流操作的断路器后执行重置，他将不能保证错误已经被消除了。因此，由于这个问题并没有被正确地解决，当用户执行重置时，将可能产生剩余电流操作的断路器的后续的间隔紧密的释放。
发明内容
本发明的目标在于提供一种特别用于剩余电流操作的断路器等装置的自动重置装置，其允许在重置剩余电流操作的断路器之前，检查系统的正确操作和状态。
在该目标中，本发明的一个目的是提供一种特别用于剩余电流操作的断路器的自动重置装置，其在执行实际的重置之前检查系统的状态，然后通过在临时的错误发生后再次闭合剩余电流操作的断路器来为用户提供连续服务的保证。
本发明的另一个目的是提供一种自动重置装置，它还能够检查装置自身和系统的正确连接。
本发明的再一个目的是提供一种自动重置装置，可以高度可靠地、相对简单地提供并且在花费上有竞争性。
将在下文中详细说明的所述目标和这些以及其它目的，可通过一种自动重置装置实现，该装置包括用于自动重置一个在负载的上游的连接到电线的剩余电流操作的断路器的致动器，其特征在于，它包括一个用于驱动所述致动器的控制装置，该控制装置在所述负载的上游连接剩余电流操作的断路器的上游和剩余电流操作的断路器的下游，以在剩余电流操作的断路器被释放时旁路该剩余电流操作的断路器，该控制装置包括用于检查重置装置与所述电线的连接的电路以及用于检测漏电流的电路，以便在驱动所述致动器自动地重置剩余电流操作的断路器之前，检查漏电流的存在。所述控制装置通过插入一个断路器与所述电线相连，所述断路器被配置为在所述剩余电流操作的断路器的释放之后闭合。
附图说明
此外，通过附图的非限制性的例子的阐释，本发明的特征和优点将通过根据本发明的重置装置的优选的、而并非排它的实施例的说明变得更加清楚，其中：
图1是根据本发明的装置的通用电路图。
图2是根据本发明的重置装置的方框图。
图3是根据本发明的重置装置的电路图。
具体实施方式
参照上述附图，根据本发明，与一个剩余电流操作的断路器关联的重置装置包括控制装置1，其一方面可以通过连接点3和4方便地与剩余电流操作的断路器2相连，所述连接点从剩余电流操作的断路器2的下游和负载5的上游连接控制装置1，另一方面通过连接点6和7从剩余电流操作的断路器2的上游连接控制装置1，以旁路剩余电流操作的断路器而不用与接地系统连接。
图1和其它附图示出了带有相线8和中线9的电线。
因此，由一个控制板方便地形成的控制装置1被插入到电线和剩余电流操作的断路器2之间以及剩余电流操作的断路器2与负载5之间，从而构成一个该剩余电流操作的断路器的旁路。
一个适用于驱动剩余电流操作的断路器2的重置的致动装置10，与控制板1相连接，并利用控制板1与电线的连接经由电线8、9提供电源。
具体而言，该控制装置1包括控制单元15，其与电源装置16相连接，以便获得一个等于该装置的干线电源电压(mains supply voltage)一半的控制电压。此外，该电源装置还包括一个用于控制单元的电源17。
此外，该装置有一个由参考数字18表示的、用于检测电源电压的存在和值的电路，其与控制单元15相连接，并发送与电源电压的存在和值相关的响应信号19到控制单元。
一个用于检测与系统相连的电缆并与其它电路电分离的电路20也与控制单元15相连以检验电缆的正确连接，例如，检验该重置装置已正确地连接到系统。
电路20在输入端接收请求检测电缆连接的信号21，并且将表示电缆检测结果的信号22输出到控制单元15。
此外，根据本发明的装置还包括用于检测所连接的系统的漏电流的电路23；该检测利用从干线电压获得的单向脉冲电压来发生，如果发生接地故障，在干线上关闭所述电压；最后，该装置包括用于在系统检验周期内防止电击的电路24。
该控制单元15发送一个致动信号25到热致动器10以激活重置装置。
参照附图，根据本发明的该重置装置的操作如下。
控制装置1在相关联的剩余电流操作的断路器释放以后，通过闭合接头30来提供电源，其打开接头2并断开系统的电源。
该控制装置立即闭合继电器31，将被检测的系统与先前描述的测量电路相连接。
控制单元15发送请求检测电缆21的信号到检测电缆连接的控制电路20，以测定在测试点A和B之间存在阻抗.此测定表示在继续测试序列之前，该装置已与系统正确连接.超过预置值的阻抗值将阻止重置装置继续进行测试序列.
此时，控制单元15通过电路23检测通地漏电流的可能的存在，如果通地漏电流超过预置阈值，它将阻止该装置自动重新闭合。
如果上述两个检测中有一个发生了错误，该装置将通过打开具有稳定光的LED来报告该异常。
如果第一步最后得到一个肯定的结果，那么该控制单元将为热致动器10供电，以便重置该装置。该热致动器是一个烫蜡(hot-wax)致动器，其重置相关联的剩余电流操作的断路器，从而为与其相连的系统供电。
如果剩余电流操作的断路器在预置时间内两次失败，该重置装置将不再尝试第二次重置，而保持在阻止状态中，其通过上述的LED的固定光亮来进行指示，直到相关联的断路器被手动重置。
实质上，根据本发明的该自动重置装置，在能够实际驱动剩余电流操作的断路器的自动重置之前，允许检测重置装置的连接和任何发生的漏电流。
实际上，可以发现由于允许在自动重置操作之前在该装置和该系统上执行一系列的检测，以便在可以保证系统后续的正确操作的条件下进行重置，因此根据本发明的该装置已经完全取得了预期的目标和目的。
因此，设计该装置以便可以接受在附加的权利要求范围内的多种修改和变形，此外其所有的细节可以由技术性的等价元素组成。
实际上，所使用的材料以及可能的形状和尺寸可以根据需求和技术状态来设计。
