Description

一种新型的电涌保护器模组
本申请要求在2018年4月25日提交中国专利局、申请号为201820599661.4、发明名称为“一种新型的电涌保护器模组”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及一种电涌保护器，尤其涉及一种新型的电涌保护器模组。
背景技术
在移动通信系统中，通信基站安装在户外的高塔上，由于其安装环境极易受到雷电危害，通信基站均内置电涌保护器，电涌保护器均有热脱离装置，目前的热脱离装置基本上采用120℃-145℃的低熔点合金焊点，随着通信技术的发展，5G移动通信基站设备的功率密度增大，同时又有小型化的趋势，导致基站设备内部的工作温度高达105℃。随着基站设备内部工作温度的变高，目前，基站内部的电涌保护器的热脱离装置面临在工作温度下提前断开失效，失去浪涌保护功能。对设备内用的电涌保护器件的工作温度也有提升需求，需要提高热保护装置的熔点温度。热保护装置的熔点温度提高以后，如果没有改善压敏电阻失效发热时热量向脱离焊点的传导途径，会出现压敏电阻在失效出现热击穿时，由于传导途径的热阻过大，热保护装置的脱离焊点没有达到熔点温度，未能将失效的压敏电阻在短路失效前脱离电路，使得压敏电阻出现短路失效，该失效会导致压敏电阻出现高温和大电流电弧现象，存在导致绝缘失效和起火的危险。
发明内容
为解决上述技术问题，本申请的技术目的在于提供一种新型的电涌保护器模组，其能够在出现异常过电压时，由多个浪涌保护器件发热并向脱离焊点传递热量，具有快速遮断灭弧效果，使脱离焊点在浪涌保护器件异常时及早断开，降低绝缘失效和起火的危险。
本申请的目的通过下列技术方案实现：

进一步地，进线压敏电阻包括第一压敏电阻单元和第二压敏电阻单元；第一压敏电阻单元的一端引出相线端，另一端与热脱离单元连接；第二压敏电阻单元的一端引出零线端，另一端与热脱离单元连接；形成相线端、第一压敏电阻单元、热脱离单元、第二压敏电阻单元、零线端的串联电路；弹性件包括第一弹性件和第二弹性件，绝缘件包括第一绝缘件和第二绝缘件，第一弹性件置于第一绝缘件的开口中，第二弹性件置于第二绝缘件的开口中；低熔点合金包括第一低熔点合金和第二低熔点合金，引线包括第一引线和第二引线；第一引线贯穿所述第一弹簧的通道，并通过第一低熔点合金连接至第一压敏电阻单元；第二引线贯穿所述第二弹簧的通道，并通过第二低熔点合金连接至第二压敏电阻单元。
进一步地，电涌保护器模组还包括接地压敏电阻单元，接地压敏电阻单元的一端引出接地端，另一端与热脱离单元的连接件连接。
进一步地，电涌保护器模组还包括放电管，放电管的一端连接至所述连接件，另一端连接至接地压敏电阻单元，用于隔离对地的漏电流。
进一步地，电涌保护器模组还包括放电管，放电管的一端连接至连接件，另一端引出接地端，用于隔离对地的漏电流。
进一步地，进线压敏电阻设置有隔离件。该隔离件用于提升压敏电阻间的绝缘耐压，可以是膜类的、片块状类的，还可以是内架上的具有隔离的特征结构。
进一步地，新型的电涌保护器模组还包括失效指示装置。该失效指示功能可以进行方便、高效的指示识别。
进一步地，绝缘件的一侧与放置该绝缘件的内架线线接触，如此使得与 内架的接触面积最小，在低熔点合金熔融后滑动时受到的阻力最小。
进一步地，该弹性件为弹簧。
进一步地，该连接为焊接。
本申请的有益效果至少包括：
由多个浪涌保护器件发热并向脱离焊点传递热量，使低熔点合金脱离焊点在浪涌保护器件异常时及早断开，降低绝缘失效和起火的危险，本申请的电涌保护器组件小型集成化、低高度，指示效果明显，安全性好，安装维护便捷。

在下文中，将参照附图以实施例的方式对本申请进行更加详细的描述。其中仅示出了一些实施例，但本申请在实际应用中可以体现为多种不同的形式，不应该局限于本文中所提出的实施例，提供这些实施例的目的是为了更好地理解本申请。
本申请提供一种新型的电涌保护器模组，其包括
互相串联的第一元件和第二元件，其中第一元件的电阻随其两端的电压的变化而变化，第二元件能够传导电流，但该电流的传导受温度变化的阻碍；
还包括无法传导电流的第三元件，以及
第四元件；
该第三元件用以在电流受阻时产生推动第四元件的力，使第四元件发生移动以消除电涌保护器中的潜在危害。
实施例1
如图1-9所示，一种新型的电涌保护器模组包括外壳1、内架2、盖板3、第一压敏电阻单元4a、第二压敏电阻单元4b、接地压敏电阻单元4c、热脱离装置5、放电管6以及隔离件7。
放电管6一端与接地压敏电阻单元4c焊接后包封为一体，另一端与热脱离装置5的弹性元件501通过焊接连接。接地压敏电阻单元4c与内架2配合装入盖板3中，引出PE外露脚。第一压敏电阻单元4a和第二压敏电阻单元4b分别粘附一隔离件7，装入盖板3中，分别引出相线端(L)和零线端(N)。
热脱离装置5包括第一弹簧503a和第二弹簧503b，第一绝缘件504a和第二绝缘件504b，第一低熔点合金脱离焊点505a和第二低熔点合金脱离焊点505b，弹性元件501，以及设置在弹性元件501上的第一引线502a和第二引线502b。弹性元件501由弹性金属材质冲制而成，弹性元件501根据连接需要，冲制一定数量的孔特征，便于引线的固定与连接，引线穿入孔内进行压接，也可以焊接或先压接后焊接的连接固定方式。第一、第二绝缘件504a、504b优选产气绝缘件。第一绝缘件504a具有中孔，该第一弹簧503a至于该中孔中，第一弹簧503a具有中空的通道，第一引线502a贯穿该中空通道，并通过第一低熔点合金脱离焊点505a焊接至第一压敏电阻单元4a。第二绝缘件504b具有中孔，该第二弹簧503b至于该中孔中，第二弹簧 503b具有中空的通道，第二引线502b贯穿该中空通道，并通过第二低熔点合金脱离焊点505b焊接至第二压敏电阻单元4b。正常状态时，第一、第二弹簧503a、503b一端抵靠绝缘件，另一端抵靠弹性元件501，呈压缩态。同时，绝缘件在弹簧的反弹力作用下的一端抵靠在低熔点合金焊点上。第一、第二绝缘件504a、504b一侧与内架2仅通过边缘线线接触，尽量减少接触面积，减小摩擦力。
如图6-7所示，第一压敏电阻单元4a中，正电极片401和背电极片403焊接在银片402银面上。第二压敏电阻单元4b中，正电极片404和背电极片406焊接在银片405的银面上。正电极片401和正电极片404，背电极片403和背电极片406可以是镜像、相同或不同关系的电极片。如图8所示，接地压敏电阻单元4c中，正电极片407和背电极片409焊接在银片408的银面上，背电极片409另一面与放电管6焊接，背电极片409开孔位置与放电管6的排布位置，降低了包封异常，减低了成本，实现节省空间，降低产品高度的设计理念。
由此，本实施例中，形成相线端、第一压敏电阻单元4a、第一低熔点合金脱离焊点505a、第一引线502a、弹性元件501、第二引线502b、第二低熔点合金脱离焊点505b、第二压敏电阻单元4b、零线端的串联电路，形成差模保护。同时，形成相线端、第一压敏电阻单元4a、第一低熔点合金脱离焊点505a、第一引线502a、弹性元件501、放电管6、接地压敏电阻单元4c的串联电路，以及零线端、第二压敏电阻单元4b、第二低熔点合金脱离焊点505b、第二引线502b、弹性元件501、放电管6、接地压敏电阻单元4c的串联电路，形成共模保护。从而达到“Y”型结构的单相电路全模保护。
在出现过电压时，压敏电阻没有完全短路失效之前，热脱离装置5直接取热于压敏电阻。当低熔点合金脱离焊点在热量的作用下熔融，从而断开引线与压敏电阻单元之间的连接，弹性元件501回弹，第一、第二弹簧503a、503b推动第一、第二绝缘件504a和504b快速遮断脱离，电弧灼烧绝缘件产生的大量气体在绝缘件的推动下，会将电弧吹离绝缘件，进一步的加速电弧的拉长，从而有效的利用压敏电阻的阻值进行电流限制，确保熄灭电弧。
电涌保护器模组还包括失效指示功能。通过外壳1的可视窗口101可以便捷有效的看到模组失效前后的颜色变化，达到失效指示功能。
实施例2
实施例2与实施例1的不同点主要在于实施例2不包括放电管。如图10-13所示，弹性元件501与接地压敏电阻单元4c的背电极片409连接后包封为一体。弹性元件501与背电极片409也可以是先包封后焊接，也可以是弹性元件501与背电极片409融为一体的连接方式。
实施例3
实施例3与实施例1的不同在于实施例3不包括接地压敏电阻。如图14所示，放电管6一端连接至弹性元件501，另一端引出接地端。
以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
