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9，一种石墨浪涌保护器，包括脱扣装置、石墨间隙模块1、第一指示片2、第二指示片3、指示架4、动力臂和5轴承6；
所述第一指示片2设置在所述指示架4上，所述第二指示片3重叠设置在所述第一指示片2下，所述指示架4套接在所述轴承6上，所述轴承6与所述动力臂的一端固定连接，所述动力臂的另一端与所述脱扣装置固定连接，所述脱扣装置设置在所述石墨间隙模块1的引线端上；
所述脱扣装置脱扣时推动所述动力臂绕着所述轴承6转动，所述第一指示片2与所述第二指示片3脱离重叠。
从上述描述可知，本公开的有益效果在于：一种石墨浪涌保护器，在浪涌来临时触发石墨间隙模块1上的脱扣装置，使得动力臂在脱扣装置的推力下围绕并带动轴承6转动。轴承6带动指示架4发生转动，从而第一指示片2发生位移，脱离与第二指示片3的重叠。运维人员在巡视时，通过浪涌保护器上第一指示片2和第二指示片3的相对位移变化，便能够直观地判断当前的浪涌保护器发生过热失效，从而及时采取相应措施，避免造成供电事故，降低损失。
进一步地，所述脱扣装置包括金属簧片7、合金感温体、滑块8和弹簧9；
所述金属簧片7的一端通过所述合金感温体与所述石墨间隙模块1的引线端焊接固定，且另一端用于外接相线、保护线或接地线，所述金属簧片7与所述滑块8抵触连接，所述滑块8与所述弹簧9的一端固定连接，所述动力臂的另一端与所述滑块8固定连接；
所述弹簧9处于蓄力状态，所述滑块8在所述弹簧9复位时推动所述金属簧片7远离所述石墨间隙模块1，且推动所述动力臂绕着所述轴承6转动。
从上述描述可知，外部的相线、保护线或接地线与石墨间隙模块1的引线端之间通过金属簧片7实现电连接。金属簧片7的一端通过合金感温体焊接在石墨间隙模块1的引线端上，形成一个弹力扣。滑块8和处于蓄力状态的弹簧9组成一个蓄能结构。当发生过热失效时，石墨间隙模块1的引线端的热量传递至合金感温体上。过高的温度使得合金感温体发生熔融，金属簧片7与石墨间隙模块1的引线端之间脱焊。在金属簧片7的弹力以及蓄能结构的抵触作用下，金属簧片7脱开与石墨间隙模块1的连接，浪涌保护器与外部电路断开连接，避免发生一些因浪涌保护器失效后再次承受浪涌而造成的用电事故。
进一步地，还包括触动杆10和设置在告警模块上的微动开关11；
所述弹簧9的另一端与所述触动杆10的一端固定连接，所述触动杆10的 另一端与所述微动开关11的动触点抵触连接。
从上述描述可知，弹簧9的另一端还接有用于抵住微动开关11的触动杆10。当浪涌保护器过热失效后，弹簧9复位，触动杆10在失去弹簧9的作用力后不足以抵触微动开关11，微动开关11由常闭变为常开，从而触发告警模块。实现失效告警。
进一步地，所述告警模块包括第一印刷电路板12和第二印刷电路板13；
所述微动开关11设置在所述第一印刷电路板12上，所述第一印刷电路板12通过连接导线与所述第二印刷电路板13电连接，所述第二印刷电路板13上设有外接插口14。
从上述描述可知，微动开关11由常闭变为常开时候，相应的改变了第一印刷电路板12和第二印刷电路板13所组成的电路结构，并可通过外接插口14将这一变化信息传递至外部。
进一步地，包括插脚15和插座16；
所述石墨间隙模块1的引线端均外接有所述插脚15和所述插座16，所述插脚15与所述插座16拔插连接，所述插座16上设有外接口17，所述石墨间隙模块1上不同的引线端通过外接口17分别与相线、中性线和保护线相连。
从上述描述可知，浪涌保护器上的石墨间隙模块1通过插脚15与插座16的拔插设计实现灵活组合，以应对不同的设计需求。
进一步地，所述插座16包括插脚夹18、导线夹19、插脚夹端子20和导线夹19端子；
所述插脚15与所述插脚夹18拔插连接，所述导线夹端子21设在所述导线夹19上，所述插脚夹端子20设在所述插脚夹18上，所述导线端子21与所述插脚夹端子20卡扣连接，所述外接口17设置在所述导线夹19上。
从上述描述可知，插脚15与插座16上的插脚夹18拔插链接。外接的中性线、保护线和相线均通过导线夹19固定在插座16上。
进一步地，还包括连接插排22；
所述连接插排22分别通过螺钉夹紧固定在不同的所述导线夹19上。
从上述描述可知，连接插排22用于连接不同插座16上的导线夹19。连接插排22可将不同的石墨间隙模块1所对应的插座16连接在一起，不仅减少了 浪涌保护器上的走线，还为不同的石墨间隙模块1之间建立的物理连接，增加浪涌保护器整体结构的稳定性。
进一步地，还包括透明视窗23；
所述透明视窗23设置在所述第一指示片2和所述第二指示片3的重叠方向上。
从上述描述可知，透明视窗23方便运维人员观察第一指示片2和第二指示片3之间相对位移的变化，以判断浪涌保护器是否失效。
进一步地，其特征在于，所述石墨间隙模块1均为石墨多间隙结构。
从上述描述可知，石墨多间隙结构设计为多层间隙连续放电，每层之间相互绝缘，提升了浪涌保护器的放电能力和热稳定性。
请参照图1至图3所示，本公开的实施例一为：
一种石墨浪涌保护器，如图1和图2所示包括脱扣装置、石墨间隙模块1、第一指示片2、第二指示片3、指示架4、动力臂和5轴承6。其中，第一指示片2设置在指示架4上，所述第二指示片3重叠设置在所述第一指示片2下，指示架4套接在轴承6上，轴承6与动力臂的一端固定连接，动力臂的另一端与脱扣装置固定连接，脱扣装置设置在石墨间隙模块1的引线端上。脱扣装置脱扣时推动动力臂绕着轴承6转动，第一指示片2与第二指示片3脱离重叠。在本实施例中，在浪涌来临时石墨间隙模块1上的脱扣装置被触发，使得动力臂在脱扣装置的推力下围绕并带动轴承6转动。轴承6带动指示架4发生转动，从而第一指示片2发生位移，脱离与第二指示片3的重叠。运维人员在巡视时，通过浪涌保护器上第一指示片2和第二指示片3的相对位移变化，便能够直观地判断当前的浪涌保护器发生过热失效，从而及时采取相应措施，避免造成供电事故，降低损失。
如图3所示，脱扣装置包括金属簧片7、合金感温体、滑块8和弹簧9。其中，金属簧片7的一端通过合金感温体与石墨间隙模块1的引线端焊接固定，且另一端用于外接相线、保护线或接地线，金属簧片7与滑块8抵触连接，滑块8与弹簧9的一端固定连接，动力臂的另一端与滑块8固定连接。弹簧9处于蓄力状态，滑块8在弹簧9复位时推动金属簧片7远离石墨间隙模块1，且推动动力臂绕着轴承6转动。上述为脱扣装置的具体结构设计，其实际的运作原 理为:
金属簧片7的一端通过合金感温体焊接在石墨间隙模块1的引线端上，形成一个弹力扣。滑块8和处于蓄力状态的弹簧9组成一个蓄能结构。当发生过热失效时，石墨间隙模块1的引线端的热量传递至合金感温体上。过高的温度使得合金感温体发生熔融，金属簧片7与石墨间隙模块1的引线端之间脱焊。在金属簧片7的弹力以及蓄能结构的抵触作用下，金属簧片7脱开与石墨间隙模块1的连接，浪涌保护器与外部电路断开连接，实现脱扣。
在本实施例中，包括透明视窗23。透明视窗23设置在第一指示片2和第二指示片3的重叠方向上。透明视窗23用于方便运维人员观察第一指示片2和第二指示片3之间相对位移的变化，以判断浪涌保护器是否失效。
另外，在本实施例中，第一指示片2和第二是指示片可以设置成不同的颜色，例如红色与绿色，用于表示浪涌保护器正常和失效两种状态。
请参照图4、图6和图8，本公开的实施例二为：
一种石墨浪涌保护器，如图4所示，如图1所示，还包括触动杆10和设置在告警模块上的微动开关11。其中，弹簧9的另一端与触动杆10的一端固定连接，触动杆10的另一端与微动开关11的动触点抵触连接。本实施例中，弹簧9的另一端还接有用于抵住微动开关11的触动杆10。当浪涌保护器过热失效后，弹簧9复位，触动杆10在失去弹簧9的作用力后不足以抵触微动开关11，微动开关11由常闭变为常开，从而触发告警模块。实现失效告警。
在本实施例中，告警模块包括第一印刷电路板12和第二印刷电路板13。微动开关11设置在第一印刷电路板12上，第一印刷电路板12通过连接导线与第二印刷电路板13电连接，第二印刷电路板13上设有外接插口14。
请参照图5、图6、图7和图9，本公开的实施例三为：
一种石墨浪涌保护器，在上述实施例一或二的基础上，如图1所示，包括插脚15和插座16。其中，插座16包括插脚夹18、导线夹19、插脚夹端子20和导线夹端子21。
如图5至图7所示，石墨间隙模块1的引线端均外接有插脚15和插座16，石墨间隙模块1上不同的引线端通过外接口17分别与相线、中性线和保护线相连插脚15与插脚夹18拔插连接，导线夹端子21设在导线夹19上，插脚夹端 子20设在插脚夹18上，导线夹端子21与插脚夹端子20卡扣连接，外接口17设置在导线夹19上。
如图9所示，还包括连接插排22，连接插排22分别通过螺钉夹紧固定在不同的导线夹19上。
综上所述，本公开公开了一种石墨浪涌保护器，在浪涌来临时触发石墨间隙模块上的脱扣装置，使得动力臂在脱扣装置的推力下围绕并带动轴承转动。轴承带动指示架发生转动，从而第一指示片发生位移，脱离与第二指示片的重叠。运维人员在巡视时，通过浪涌保护器上第一指示片和第二指示片的相对位移变化，便能够直观地判断当前的浪涌保护器发生过热失效，从而及时采取相应措施，避免造成供电事故，降低损失。石墨间隙模块与插座之间的拔插设计使得浪涌保护器运用起来灵活方便。并且，在浪涌保护器上装配有失效告警装置，使得浪涌保护器失效后可触发告警。运维人员通过透明视窗和告警信息便能够判断浪涌保护器是否失效，并及时做出相应的维护措施。
