一种用于测试电力工程设备的测试装置(1),其包括电连接到过电压保护装置(2)的至少一个连接插口(4)。所述过电压保护装置(2)包括至少一个过电压保护元件(5)并且配置为使得所述至少一个过电压保护元件(5)为可替换的。
Description
技术领域
本发明涉及用于电力工程设备的测试装置以及制造用于电力工程设备的测试装置的方法。具体地,本发明涉及用于分别测试和检查高压和中压电气系统中的运行资源,例如电力变压器、电流或电压转换器、断路器、保护继电器、发电机、马达或电缆系统等,以及制造这种测试装置的方法。
背景技术
在用于测试高压或中压电气系统中运行资源的测试装置中,可能会经常发生过电压,所述过电压通过所述测试装置的输入插口或输出插口到达或施加到所述测试装置内部并且可能损坏或者甚至破坏所述测试装置此处的部件,尤其是所述测试装置的电子器件。因此,诸如抑制二极管或过电压气体放电器的过电压保护元件安装在常规测试装置中以保护所述测试装置免受这种过电压或电压增加。
图1示意性示出了根据现有技术的测试装置1。所述测试装置1包括具有多个插口4或连接端子4的壳体9,每个插口4提供用于施加待被测试装置1评估的输入信号或经由各插口输出测试装置1的测试信号。在图1所示实例中,为了保护测试装置1免受过电压,每个插口4连接到固定安装在壳体9中的单独的过电压保护元件3。
例如,每个保护元件3可以是过电压气体放电器。在过电压气体放电器的情况下,如果超过预定电压使得过电压对地放电时,则会引发小电弧。这种过电压气体放电器还可以配备有短路弹簧。在这种情况下,如果电弧发生过长则间隔器会融化,然后短路弹簧可使得过电压气体放电器的接触短路。因此,所述过电压降低至几乎为零使得测试装置的电子器件可永久地得以保护以防止故障或失效。
同样地,抑制二极管诸如TransZorb二极管可用作保护元件,其具有限压效果但是如果发生过电压或过载则会导致电路短路。
常规过电压保护装置的共同点在于如果发生过电压,分别使用的保护元件与保险丝类似地被破坏以保护所述测试装置免受过电压。为了修复或维修其中这种过电压保护元件已经被过电压破坏的测试装置,必须打开所述测试装置的壳体并且必须进行大量、耗时且昂贵的维修。
发明内容
因此,本发明的目的在于提供解决该问题的用于电力工程设备的测试装置以及制造用于电力工程设备的测试装置的方法,即使在过电压保护元件被损坏或破坏之后,也能够以简单和经济的方式修复所述测试装置。
根据本发明,提供了用于电力工程设备或电力工程装置和布置的测试装置以及制造这种测试装置的方法,其中所述测试装置包括至少一个用于接收输入信号或用于输出输出信号的插口或连接端子,所述至少一个插口电连接到过电压保护装置。所述过电压保护装置包括至少一个过电压保护元件并且配置为使得所述至少一个过电压保护元件是可替换的。
因此,即使在所述过电压保护元件损坏或破坏之后,所述过电压保护元件也可不费力地被替换,所以所述测试装置可通过简单的方式经济地修复。
在本发明意义上的“插口”被理解为所述测试装置的每个连接装置,通过其可接收待提供给所述测试装置的输入信号(例如待被所述测试装置评估的测量信号)或可输出所述测试装置的输出信号(尤其是待应用到被测试的装置的测试信号)。因此,该连接装置还可以包括内置插头连接器或任何其他合适的电连接和连接器。
所述测试装置尤其可被设计为用于测试电力工程设备或高电压或中电压系统的运行资源的测试装置。
优选地,所述测试装置的过电压保护装置配置为使得所述过电压保护元件的替换可如保险丝的替换一样地进行并且不打开所述测试装置的壳体和不需要工具。最多可能必需最简单的工具如螺丝刀以替换过电压保护元件。
根据一个优选的实施方案,所述至少一个插口通过二极管装置连接到所述至少一个过电压保护元件,单独的二极管使得电流只在一个方向上流过并且连接使得通过所述二极管装置确保额外的保护。
根据本发明另一个实施方案,所述测试装置包括多个插口,每个插口电连接到相同的过电压保护元件。或者,每个插口可连接到单独的过电压保护元件,所有过电压保护元件提供在共同的可替换模块或单独的可替换模块中。在为每个插口使用单独的过电压保护元件的情况下,即使过电压保护元件中的另一个应该被过电压损坏或破坏,则至少那些依然起作用且情况良好的过电压保护元件保护的插口仍可使用。
所述至少一个过电压保护元件优选为抑制二极管,例如TransZorb二极管,或者过电压放电器或过电压气体放电器,例如气体放电管或任何其他类型的气体放电装置,所述过电压气体放电器任选地提供有短路弹簧。
附图说明
以下,将参照附图通过优选实施方案进一步详细地描述本发明。
图1示意性示出了根据现有技术的测试装置。
图2示意性示出了根据本发明一个实施方案的用于电力工程设备的测试装置。
图3示意性示出了根据本发明另一个实施方案的用于电力工程设备的测试装置。
具体实施方式
在图2中所示的测试装置1中,至少一个插口或连接端子4提供在测试装置的壳体9处。例如,插口4可以是用于接收相应输入信号的输入插口,以便通过测试装置1评估被测试的装置(未示出)处选定的测量信号并且分别检查被测试的装置的运行和条件。被测试的装置具体可以是中压或高压系统的运行资源,例如电力变压器、电流转换器、电压转换器、断路器、保护继电器、发电机、马达、或电缆系统等。例如,插口4还可以是测试装置1的输出插口,通过其可将测试信号应用到各被测试的装置。
为了过电压保护,插口4通过连接线7电连接到过电压保护装置2。至少一个过电压保护元件5提供在过电压保护装置2内,例如其可以是抑制二极管,例如TransZorb二极管,或过电压放电器,尤其是过电压气体放电器。
过电压保护装置2优选以可替换模块的形式布置在测试装置1中或测试装置1处,使得如果过电压保护元件5应该损坏或破坏则过电压保护元件5可以通过替换模块而容易地被替换并且优选不用工具。为此目的,过电压保护装置2的模块在合适的位置处可具有在插入模块时连接各过电压保护元件5和连接线的电接触8。尤其是,模块可提供有插头接触8,使得为了替换过电压保护元件5,模块可以容易地从壳体9中拉出并且被具有起作用的过电压保护元件5的新模块替换,之后将其再插入到壳体9中。当然,还可以在已经移出所述模块之后仅替换过电压保护元件5,然后再次将具有新过电压保护元件的同一模块插入到壳体9中。
过电压保护装置2的布置和构造优选使得过电压保护装置2和过电压保护元件5分别可以如保险丝一样替换并且不必打开测试装置1的壳体9。因此,可避免大量的维修,测试装置1不需要花费大量的时间即可再次投入运行。
在图1中所示的实施方案中,插口4不是通过连接线7直接连接到过电压保护装置2,而是通过二极管装置5,其中单独的二极管以使得通过二极管提供测试装置1的额外保护的方式连接到插口4和连接线7。
如以上已描述的,过电压保护元件5可以是过电压放电器,尤其是过电压气体放电器。在过电压气体放电器中,如果超过预定电压使得过电压对地放电时,会引起小电弧。这种过电压气体放电器还可配备有短路弹簧。在这种情况下,如果电弧发生过长,则间隔器融化,然后短路弹簧会使过电压气体放电器的接触短路。然后过电压变成几乎为零,使得所述测试装置的电子器件永久地得以保护以防止故障或失效。
也可使用抑制二极管作为过电压保护元件5,所述抑制二极管具有限压功能,仅在过电压或过载发生时引起电短路。
图3示出了本发明的另一实施方案。
图3中所示的测试装置1包括通过二极管装置6各自连接到过电压保护装置2的一个相同的过电压保护元件5的多个插口4。除此之外,图3中所示实施方案与图2的实施方案相对应,因此可参照所有以上对图2的描述。
或者,每个插口4还可以在连接到共同的过电压保护装置2或单独的可替换过电压保护装置中的各自的过电压保护元件5。
