详细描述
为详细说明本公开的技术内容、所实现目的及效果，以下结合实施方式并配合附图予以说明。
请参照图1至图6，
一种浪涌保护器，包括第一放电管1、第二放电管2、第一脱扣装置和第二脱扣装置；
所述第一放电管1的一引线端和所述第二放电管2的一引线端均与所述第一脱扣装置电连接，所述第二放电管2的另一引线端与所述第二脱扣装置电连接；
所述第一放电管1的另一引线端用于外接相线，所述第一脱扣装置用于外接中性线，所述第二脱扣装置用于外接保护线。
从上述描述可知，提供一种浪涌保护器，第一放电管1、第二放电管2、第一脱扣装置和第二脱扣装置组成一个外接中性线、保护线和相线的三电极浪涌保护器。第一脱扣装置可预防从相线或中性线来的浪涌。第二脱扣装置可预防从相线或保护线来的浪涌。整体上实现了单相防护，在浪用来临时及时脱开电路，保护其他设备。本公开的浪涌保护器中第一放电管的另一引线端、第一脱扣装置和第二脱扣装置还分别引出电极引脚，从而更便于外接电线。
进一步地，还包括固定框架，所述第一脱扣装置包括第一弹簧3、第一金属簧片4、第一滑块5和第一感温金属体，所述第二脱扣装置包括第二弹簧7、第二金属簧片8、第二滑块9和第二感温金属体；
所述第一放电管1和所述第二放电管2均固定在所述固定框架6上，所述第一金属簧片4的一端通过所述第一感温金属体固定连接同时与所述第一放电管1的一引线端和所述第二放电管2的一引线端焊接固定，所述第一金属簧片4的另一端与所述第一滑块5固定连接，所述第一滑块5与所述第一弹簧3的一端固定连接，所述第一弹簧3的另一端固定在所述固定框架6上；
所述第二金属簧片8的一端通过所述第二感温金属体与所述第二放电管2的第二引线端焊接固定，所述第二金属簧片8的另一端与所述第二滑块9固定连接，所述第二滑块9与所述第二弹簧7的一端固定连接，所述第二弹簧7的另一端固定在所述固定框架6上；所述第一弹簧3和所述第二弹簧7均处于蓄力状态，所述第一弹簧3与所述第一滑块5固定连接的一端的弹力 方向远离所述第一放电管1和所述第二放电管2，所述第二弹簧7与所述第二滑块9固定连接的一端的弹力方向远离所述第二放电管2；
所述第一金属簧片4用于外接中性线，所述第二簧片7的另一端用于外接保护线。
从上述描述可知，第一金属簧片4和第一感温金属体将第一放电管1的一引线端和第二放电管2的一引线端焊接在一起，形成弹力扣，并在第一金属簧片4上设置了由第一弹簧3和第一滑块5组成的脱扣结构。这样，在浪涌过来时，第一放电管1或第二放电管2过热时都会将热量传递至第一感温金属体上，以致使第一感温金属体周围脱焊，第一金属簧片4、第一放电管1和第二放电管2的连接处松动。在脱扣结构中第一弹簧3的弹力和第一簧片的弹力作用下，第一金属簧片4脱开，则第一放电管1与第二放电管2之间的连接断开，实现自动脱扣。第二弹簧7、第二滑块9和第二感温金属体的作用原理与上述内容相似。
进一步地，所述固定框架6上设有第一滑槽10和第二滑槽11，所述第一滑块5与所述第一弹簧3的一端固定连接；
所述第一滑块5和所述第一弹簧3均设置在所述第一滑槽10上，所述第一滑槽10的一端设有第一封闭结构12，所述第一滑块5与所述第一弹簧3的一端抵触连接，所述第一弹簧3的另一端与所述封闭结构抵触连接；
所述第二滑块9和所述第二弹簧7均设置在所述第二滑槽11上，所述第二滑槽11的一端设有第二封闭结构13，所述第二滑块9与所述第二弹簧7的一端抵触连接，所述第二弹簧7的另一端与所述第二封闭结构13抵触连接。
从上述描述可知，第一弹簧3和第一滑块5均设置在第一滑槽10上。第一滑块5将第一弹簧3压缩在第一滑槽10第一封闭结构12之上。在浪涌保护器发生过热失效时，第一弹簧3推动第一滑块5在第一滑槽10上滑动并远离第一放电管1和第二放电管2。第二滑块9和第二弹簧7在第二滑槽11的运动过程与上述内容相似，不再赘述。
进一步地，还包括第一指示片14、第二指示片15、第三指示片16和第四指示片17；
所述第二指示片15和所述第一指示片14先后排列设置在所述第一滑块5上，且排列方向与所述第一弹簧3的复位方向相同；
所述第四指示片17和所述第三指示片16先后排列设置在所述第一滑块5上，且排列方向与所述第二弹簧7的复位方向相同。
从上述描述可知，第一指示片14和第二指示片15构成物理指示装置。由于第一指示片14和第二指示片15与第一弹簧3的复位方向相同，在第一弹簧3复位时，第一指示片14和第二指示片15在第一滑块5的带动下发生位移，造成原本第二指示片15的位置变成了第三指示片16，即将第一滑块5的运动演变成第一指示片14和第二指示片15的位置变化，以用来判断是否发生脱扣。第四指示片17和所述第三指示片16的作用原理则与第一指示片14和第二指示片15相同。用以构成物理指示装置的两个指示片可以用不同的颜色、形状等以示区分，以便用户能够直观地看出是否发生脱扣。
进一步地，还包括浪涌保护器外壳，所述浪涌保护器外壳还包括上框体18和下框体19；
所述上框体18与所述下框体19之间可拆卸连接。
从上述描述可知，整个浪涌保护器装在由上框体18和下框体19组成的浪涌保护器外壳之内。
进一步地，所述上框体18上对应所述第二指示片15和所述第四指示片17的位置均设有透明视窗20。
从上述描述可知，在上框体18上对应第二指示片15和第四指示片17的位置均设有透明视窗20。透明视窗20用于方便运维人员观察原本第二指示片15或第四指示片17的位置是否变成第一指示片14或第三指示片16，即用于直观地判断浪涌保护器是否发生自动脱扣。
进一步地，所述上框体18上设有通气孔21。
从上述描述可知，在上框体18上设有通气孔21，用于加快浪涌保护器内部的散热速度。
进一步地，所述第一放电管1和所述第二放电管2均为多间隙气体放电管。
从上述描述可知，第一放电管1和第二放电管2均为多间隙气体放电管，用于增强放电效果。
进一步地，所述固定框架6通过弹性胶22固定在所述浪涌保护器外壳内。
从上述描述可知，固定框架6通过弹性胶22固定在浪涌保护器外壳内，增加了浪涌保护器整体结构的稳定性，还便于拆卸。
请参照图1与图3，本公开的实施例一为：
一种浪涌保护器，包括第一放电管1、第二放电管2、第一脱扣装置和第二脱扣装置。其中，第一放电管1的一引线端和第二放电管2的一引线端均与第一脱扣装置电连接，第二放电管2的另一引线端与第二脱扣装置电连接。在本实施例中具体地，如图1所示，还包括固定框架6。第一脱扣装置包括第一弹簧3、第一金属簧片4、第一滑块5和第一感温金属体。第二脱扣装置包括第二弹簧7、第二金属簧片8、第二滑块9和第二感温金属体。其中，第一放电管1和第二放电管2均固定在固定框架6上，第一金属簧片4的一端通过第一感温金属体固定连接同时与第一放电管1的一引线端和第二放电管2的一引线端焊接固定，第一金属簧片4的另一端与第一滑块5固定连接，第一滑块5与第一弹簧3的一端固定连接，第一弹簧3的另一端固定在固定框架6上。第二金属簧片8的一端通过第二感温金属体与第二放电管2的第二引线端焊接固定，第二金属簧片8的另一端与第二滑块9固定连接，第二滑块9与第二弹簧7的一端固定连接，第二弹簧7的另一端固定在固定框架6上；第一弹簧3和第二弹簧7均处于蓄力状态，第一弹簧3与第一滑块5固定连接的一端的弹力方向远离第一放电管1和第二放电管2，第二弹簧7与第二滑块9固定连接的一端的弹力方向远离第二放电管2。在本实施例中，利用浪涌保护器在承受最大冲击电流后自身的温度高的特点，将热量传递至第一感温金属体上，以致使第一感温金属体周围脱焊，第一金属簧片4、第一放电管1和第二放电管2的连接处松动。在第一弹簧3的弹力和第一簧片的弹力作用下，第一金属簧片4脱开，则第一放电管1与第二放电管2之间的连接断开，实现自动脱扣，避免了电路发生供电事故，减少损失。
如图1和图2所示，第一放电管1的另一引线端用于外接相线，即L。 第一金属簧片4用于外接中性线，即N。第二放电管2的另一引线端用于外接保护线，即PE。图2为本公开具体应用过程中的接线方式。
另外，在本实施例中，第一放电管1和第二放电管2均为多间隙气体放电管。
请参照图1、图3至图6，本公开的实施例二为：
一种浪涌保护器，在上述实施例一的基础上，如图1和图3所示，固定框架6上设有第一滑槽10和第二滑槽11。其中，第一滑块5和第一弹簧3均设置在第一滑槽10上，第一滑槽10的一端设有第一封闭结构12，第一滑块5与第一弹簧3的一端抵触连接，第一弹簧3的另一端与封闭结构抵触连接。第二滑块9和第二弹簧7均设置在第二滑槽11上，第二滑槽11的一端设有第二封闭结构13，第二滑块9与第二弹簧7的一端抵触连接，第二弹簧7的另一端与第二封闭结构13抵触连接。上述内容为浪涌保护器内部的一些具体安装结构。固定框架6、第一弹簧3、第一滑块5等零件之间均是可拆卸连接，方便于浪涌保护器的安装与拆卸。
在本实施例中，如图1、图5和图6所示，还包括浪涌保护器外壳，浪涌保护器外壳还包括上框体18和下框体19。具体地，上框体18与下框体19之间可拆卸连接。而且，上框体18上设有通气孔21，用于加快浪涌保护器的散热速度。固定框架6通过弹性胶22固定在浪涌保护器外壳内，方便于浪涌保护器的安装与拆卸。
请参照图3和图5所示，本公开的实施例三为：
一种的浪涌保护器，在上述实施例一或实施例二的基础上，如图3所示，还包括第一指示片14、第二指示片15、第三指示片16和第四指示片17。其中，第二指示片15和第一指示片14先后排列设置在第一滑块5上，且排列方向与第一弹簧3的复位方向相同。第四指示片17和第三指示片16先后排列设置在第一滑块5上，且排列方向与第二弹簧7的复位方向相同。
如图5所示，上框体18上对应第二指示片15和第四指示片17的位置均设有透明视窗20。透明视窗20使得运维人员在巡查过程中，能够快速直观地判断浪涌保护器是否已经失效，及时减少损失。
在本实施例或其他等他实施例中，第一指示片14与第二指示片15以及第三指示片16和第四指示片17可通过设置成不同颜色来区分，例如，第一指示片14为红；第二指示片15为绿；第三指示片16为红；第四指示片17为绿。这样，运维人员通过透明视窗20观察颜色为红色时，可判断当前的浪涌保护器已经失效。
综上所述，本公开公开了一种浪涌保护器，第一放电管、第二放电管、第一脱扣装置和第二脱扣装置组成一个外接中性线、保护线和相线的三电极浪涌保护器。第一脱扣装置可预防从相线或中性线来的浪涌。第二脱扣装置可预防从相线或保护线来的浪涌。整体上实现了单相防护，在浪用来临时及时脱开电路，保护其他设备。不同颜色的指示片组成的物理指示结构，方便运维人员及时地察觉浪涌保护器已经损坏，以便及时地更换。
