Description

供电保护装置、电池储能系统和用电设备 技术领域
本申请涉及电池技术领域，尤其涉及一种供电保护装置、一种电池储能系统和一种用电设备。
背景技术
目前，大型供电保护装置广泛地应用于发电站、公司储能系统等。其中，一般通过一个供电开关继电器控制是否对外放电，关断该供电开关继电器则停止放电，闭合该供电开关继电器则开始放电。
然而，当需要关断该供电开关继电器时，如果通过该供电开关继电器的电流过大时，则常会产生拉弧等不良现象，使该供电开关继电器发生黏连，无法成功关断。
因此，如何避免在关断供电开关继电器时发生继电器黏连的情况，成为目前亟待解决的技术问题。
申请内容
本申请实施例提供了一种供电保护装置、一种电池储能系统和一种用电设备，旨在解决相关技术中在关断供电开关继电器时易发生继电器黏连的技术问题，降低继电器黏连的可能性，提升安全性。
第一方面，本申请实施例提供了一种供电保护装置，包括：供电装置；供电开关继电器，连接至所述供电装置的输出端；开关保护电路，与所述供电开关继电器并联，所述开关保护电路包括保护开关和分流元件，所述保护开关与所述分流元件串联。
在本申请上述实施例中，可选地，所述供电装置包括若干个电池模组，每个电池模组由若干个电池并联而成。
在本申请上述实施例中，可选地，所述保护开关为继电器。
在本申请上述实施例中，可选地，所述分流元件为电阻。
在本申请上述实施例中，可选地，所述电阻为阻值固定电阻或阻值可调电阻。
在本申请上述实施例中，可选地，所述供电开关继电器并联有一个或多个所述开关保护电路。
在本申请上述实施例中，可选地，每个所述开关保护电路的分流元件的电阻大小不同，相应地，多个所述开关保护电路分别对应有不同的安全等级。
在本申请上述实施例中，可选地，每个所述开关保护电路的分流元件的电阻大小相同，以及多个所述开关保护电路中的任若干个开关保护电路组成一个开关保护电路组，相应地，任一所述开关保护电路组中所有开关保护电路的开闭状态相同，多个所述开关保护电路组分别对应有不同的安全等级。
第二方面，本申请实施例提供了一种电池储能系统，包括上述第一方面中任一项所述的供电保护装置。
第三方面，本申请实施例提供了一种用电设备，包括上述第一方面中任一项所述的供电保护装置。
相关技术中，在关断供电开关继电器时，由于供电开关继电器断开电流的最大能力是一定的，当通过供电开关继电器的电流过大，甚至超出了其断开电流的最大能力所能够断开的电流时，供电开关继电器很可能会难以断开，产生黏连。
以上技术方案，针对该技术问题，可为供电开关继电器并联一个开关保护电路，该开关保护电路包括保护开关和分流元件，当供电开关继电器闭合、供电装置进行放电时，开关保护电路的保护开关是断开的，接着，当需要断开供电开关继电器时，可先闭合开关保护电路的保护开关，使保护电路导通，由于保护电路中具有分流元件，保护电路导通后，供电装置流出的原电流就部分由分流元件分流，从而降低了通过供电开关继电器的电流。由于供电开关继电器断开电流的最大能力是一定的，通过供电开关继电器的电流越小，则供电开关继电器能够成功断开的几率也就越大。最终，当供电开 关继电器104断开后，再断开保护开关1062，从而顺利停止供电。
因此，通过该技术方案，降低了供电开关继电器发生黏连的可能性，使得供电开关继电器更为安全有效，从而大大提升了供电装置的安全性。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
图1示出了本申请的一个实施例的供电保护装置的电路链接示 意图。
如图1所示，本申请实施例提供了一种供电保护装置100，包括：供电装置102、供电开关继电器104和开关保护电路106。
供电开关继电器104的第一端连接至所述供电装置102的输出端，供电开关继电器104的第二端连接至负载；开关保护电路106与所述供电开关继电器104并联，所述开关保护电路106包括保护开关1062和分流元件1064，所述保护开关1062与所述分流元件1064串联，其中，保护开关1062的一端连接至供电开关继电器104，保护开关1062的另一端连接至分流元件1064的一端，分流元件1064的另一端与供电开关继电器104的第二端相连。
以上技术方案，可为供电开关继电器104并联一个开关保护电路106，该开关保护电路106包括保护开关1062和分流元件1064，当供电开关继电器104闭合、供电装置102进行放电时，开关保护电路106的保护开关1062是断开的，接着，当需要断开供电开关继电器104时，可先闭合开关保护电路106的保护开关1062，使保护电路导通，由于保护电路中具有分流元件1064，保护电路导通后，供电装置102流出的原电流就部分由分流元件1064分流，从而降低了通过供电开关继电器104的电流。由于供电开关继电器104断开电流的最大能力是一定的，通过供电开关继电器104的电流越小，则供电开关继电器104能够成功断开的几率也就越大。最终，当供电开关继电器104断开后，再断开保护开关1062，从而顺利停止供电。
因此，通过该技术方案，降低了供电开关继电器104发生黏连的可能性，使得供电开关继电器104更为安全有效，从而大大提升了供电装置102的安全性。另外，该供电保护装置100还具有以下附加技术特征：
供电装置102包括若干个电池模组，每个电池模组由若干个电池并联而成。也就是说，本申请主要应用于供电电流巨大的情况，供电装置102内的电池模组越多，其供电能力也就越大。
保护开关1062可以为继电器，继电器是一种通过小电流控制大电流的开关，其具有自动化程度高的优势，当然，保护开关1062也可以为其他任何类型的具有开闭跳转功能的开关，而继电器
分流元件1064可以为电阻，也可以为其他任何具有阻值的元件，只要能够通过阻值对供电装置102流出的原电流进行分流，即可达到提升供电开关继电器104成功断开的几率的目的。
在本申请的一种实现方式中，所述电阻为阻值固定电阻，阻值固定电阻对应的分流能力也是固定的。
在本申请的另一种实现方式中，所述电阻为阻值可调电阻。由于：
Figure PCTCN2017093122-appb-000001
则如果供电开关继电器104的电阻为100欧姆，供电装置102流出的原电流为1.1kA，当分流元件的电阻调节至1k欧姆时，通过供电开关继电器104的电流被分流后降低至1kA，当分流元件的电阻调节至2.1k欧姆时，通过供电开关继电器104的电流被分流后降低至0.5kA。也就是说，可通过改变电阻的阻值来调节开关保护电路106的实际分流能力，使得对供电开关继电器104乃至整个系统的调节更加灵活。当然，实际场景中各元器件的电阻、电流参数不限于上述的举例说明。
需要补充是的，供电开关继电器104的第二端连接的负载，可以是任何需要电能的设备、水电站等。
下面通过另一种方式对本申请的技术方案进行描述。
首先，电池管理单元接收到停止供电信息，故可以根据该停止供电信息，闭合保护开关1062，使得开关保护电路106通路，此时，再根据该停止供电信息，断开供电开关继电器104，当供电开关继电器104成功断开后，即检测到供电开关继电器104所在支路的电流为零时，根据停止供电信息，再断开保护开关1062，最终实现停止供电的目的。其中，在分流元件1064的电阻可调的情况下，可通 过电池管理单元调节其电阻，比如，可以在电池管理单元的操作界面设置不同的电阻选项，供用户选择。
图2示出了本申请的另一个实施例的供电保护装置的电路链接示意图。
如图2所示，供电开关继电器104并联有一个或多个所述开关保护电路106，多个开关保护电路106同时进行分流，可实现更强的分流能力，从而进一步降低通过供电开关继电器104的电流，提升供电开关继电器104成功断开的几率。图2中示意性地给出了三个开关保护电路106，但实际情况中，开关保护电路106的数量不限于此。
基于此，在本申请的一种实现方式中，每个所述开关保护电路106的分流元件1064的电阻大小相同，多个所述开关保护电路106中的任若干个开关保护电路106组成一个开关保护电路106组，任一所述开关保护电路106组中所有开关保护电路106的开闭状态相同，相应地，多个所述开关保护电路106组分别对应有不同的安全等级。
比如，设置有四个开关保护电路a、b、c、d，可将其分为四组：第一组a，第二组b和c，第三组a、b和c，第四组a、b、c、d，分别对应安全等级低、中、高、最高。
另外，在本申请的另一种实现方式中，每个所述开关保护电路106的分流元件1064的电阻大小不同，相应地，多个所述开关保护电路106分别对应有不同的安全等级。这样，用户可以根据实际需求选择不同的开关保护电路106，从而可以获得不同程度的安全保护。
图3示出了本申请的一个实施例的电池储能系统的框图。
如图3所示，本申请实施例提供了一种电池储能系统300，包括图1和图2中任一实施例所述的供电保护装置100。因此，该电池储能系统300具有和图1和图2中任一实施例所述的供电保护装置100相同的技术效果，在此不再赘述。
图4示出了本申请的一个实施例的用电设备的框图。
如图4所示，本申请实施例提供了一种用电设备400，包括图1和图2中任一实施例所述的供电保护装置100。因此，该用电设备400具有和图1和图2中任一实施例所述的供电保护装置100相同的技术效果，在此不再赘述。
以上结合附图详细说明了本申请的技术方案，通过本申请的技术方案，降低了供电开关继电器发生黏连的可能性，使得供电开关继电器更为安全有效，从而大大提升了供电装置的安全性。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
