Description

电涌保护模块及电涌保护装置 技术领域
本发明涉及过电压、过电流保护技术领域，尤其涉及一种电涌保护模块及电涌保护装置。
背景技术
雷电是十大自然灾害之一。随着技术的进步，设备越来越智能，集成度越来越高，对雷电引起的瞬时过电压——电涌越来越敏感。另外，大功率设备的启停也会产生电涌。电涌保护器(或电涌保护装置)可防止电涌对设备的损坏，广泛应用于通信、建筑、轨交、电力、新能源、石油化工等行业。当电气回路线路中因为雷击或外界的干扰产生尖峰电流或者电压时，电涌保护器可以在极短的时间内导通，泄放电流，将电压限制到较低的水平，从而避免电涌对回路中其他设备造成损害。
用于配电系统的电涌保护器中，常用的元件为压敏电阻器。压敏电阻器在正常工作情况下具有非常大的电阻，相当于断路状态，而在电路中的电压超过预定值时，其电阻急剧下降，处于导通状态，可泄放大量电流，限制过电压水平。
但是，在长时间使用之后，压敏电阻器会逐步老化，漏电流逐步增大，破坏热平衡，导致产品温度不断升高。为了防止压敏电阻器由于过热引起火灾事故，通常在电涌保护器中设置热保护脱扣装置，用于在温度升高时将压敏电阻器与电路脱开，压敏电阻器与电路脱开后，电涌保护器即已失效，将失去对设备的保护作用。失效的电涌保护器上设有状态指示，以提示维护人员及时更换。而在一些无人值守的场合，还需要设计遥信装置，实现电涌保护器失效状态的远程指示。
目前，现有的电涌保护器中，内部结构复杂，而且热保护脱扣装置在将压敏电阻器与电路脱开后，还容易出现焊锡粘连问题，并可能出现电弧，从而存在一定的危险。

所述电极连接件14与所述第二电极132之间的焊料熔化时，所述蓄势弹簧16通过弹力驱动所述转动体15沿远离所述承载架12的底端的方向转动至第二位置，在所述第二位置，所述隔弧板154转动至所述电极过孔1211处且在所述电极连接件14和所述第二电极132之间。

本发明提供的脱扣机构结构简单紧凑，不仅利于减少电涌保护模块的体积，而且还利于减小生产周期。
下面根据一个具体实施方式对本发明提供的电涌保护模块进行详细描述。
在一个优选实施方式中，承载架12的具体结构如图3和图4所示，转动体15的结构如图5所示，电极连接件14的结构如图6所示，压敏电阻器13的结构如图7和图8所示。
其中，图3显示了承载架12的第一侧，图4显示了承载架12的第二侧。图9显示了压敏电阻器13安装在承载架12的第一侧的状态。
压敏电阻器13的一侧设置有第一电极131，该第一电极131自身延伸形成有第一插脚1311；在压敏电阻器13的另一侧设置有第二电极132，第二电极132朝向安装板121安装，其中第二电极132上形成有朝向所述电极过孔121凸出的凸台1321。
电极连接件14安装在承载架12的第二侧，该电极连接件14的一端形成用于与第二电极132焊接的焊接端142，该焊接端142为片状，在所述电极过孔1211处贴合焊接于第二电极132的凸台1321的表面。通过贴合焊 接的方式可以使得该焊接处厚度较小，利于减少电涌保护模块的厚度。电极连接件14的另一端形成为用于插接的第二插脚141。其中，电极连接件14的焊接端142上设置有开孔，在焊接时利于存储焊料。
为使得电极连接件14相对于承载架12定位，所述电极连接件14与所述承载架12中的一者上设置有定位柱125，另一者上设置有与所述定位柱125配合定位的定位槽143。本实施方式中在承载架12上设置定位柱125，电极连接件14上设置定位槽143，在电极连接件14与压敏电阻器13焊接后，电极连接件14通过定位槽143与定位柱125的配合定位于承载架12上。
本实施方式中，第一插脚1311从片状的第一电极131延伸并弯折形成，且第一电极131采用具有弹性的板体材料制成，从而第一插脚1311相对于承载架12具有一定的弹性，以便于插接。同样的，如图6所述，电极连接件14的第二插脚141也是在片状的电极连接件14的一端延伸并弯折形成，该第二插脚141相对于承载架12也具有一定的弹性，方便插接。
优选地，所述第一插脚1311和所述第二插脚141分别向背离端子末端的方向弯折形成有插槽(参考图6中第二插脚141所形成的插槽1411)，所述承载架12上设置有第一支撑体127和第二支撑体128(参考图3)，所述第一支撑体127插入所述第一插脚1311的插槽，所述第二支撑体128插入所述第二插脚141的插槽，以分别增加第一插脚1311和第二插脚141插接时的稳定性。
在所述承载架12的第二侧，如图3所示，在安装板121上设置有转轴122，转轴122相比电极过孔1211更靠近承载架12的底端。在本申请中，将承载架12的具有第一插脚1311和第二插脚141的一端称为底端，与此相对的另一端称为顶端。
转动件15上设置有转轴安装孔153，转动件15通过转轴安装孔153可转动地安装在转轴122上，转动体15上在远离所述转轴122的位置设置 有隔弧板154，隔弧板154处于转动体15的背离承载架12的底端的一侧；这样，在转动体15被限制在靠近承载架12底端的第一位置时，所述隔弧板154在朝向电极过孔1211的一侧并对应于所述电极过孔1211设置，这样在焊接熔化时，隔弧板154可以迅速转动至电极过孔1211处以阻挡电极连接件14焊接于第二电极132之间可能出现的焊料粘连。
其中，由于隔弧板154沿弧形旋转，因此，优选地，所述隔弧板154具有朝向所述转轴122弯曲的内圆弧边1541和相比所述内圆弧边1541远离所述转轴122的外圆弧边1542，即所述隔弧板154大致为扇形。
优选地，所述转动体15上设置有弧形限位槽，所述电极连接件14包括位于所述弧形限位槽内的弧形部分，在所述转动体15转动过程中，所述弧形部分沿所述弧形限位槽转动；
其中，所述弧形限位槽的两侧边缘分别从所述隔弧板154的所述内圆弧边1541和所述外圆弧边1542延伸形成。
其中，所述隔弧板154的靠近外圆弧边1542的位置形成有沿弧形延伸的第二状态指示部152(下面会进一步详述)，靠近内圆弧边1541的位置形成有沿弧形延伸的弧形条157，这样，如图1所示，在转动体15处于所述第一位置时，电极连接件14与第二电极132的之间的焊接点位于所述弧形条57和第二状态指示部152之间，隔弧板154位于所述焊接点的一侧，在焊接熔化时，隔弧板154直接转动至切入电极连接件14与第二电极132之间，弧形条57、第二状态指示部152以及隔弧板154两侧的边缘均有助于完全阻断电极连接件14与第二电极132之间可能出现的电弧。
本实施方式中，所述蓄势弹簧16在所述转动体15的背离所述承载架12底端的一侧，且在所述电极连接件14与所述第二电极132处于焊接状态时所述蓄势弹簧16处于拉伸状态，对所述转动体15施加拉力。在转动体15沿远离承载架底端的方向转动时，蓄势弹簧收缩。
进一步的，在所述转动体15上位于所述转轴122和所述隔弧板154之 间的位置设置有用于容纳所述蓄势弹簧16的容纳槽155，所述承载架12上设置有第一弹簧连接部123，在所述转动体15上靠近所述容纳槽155的位置设置有第二弹簧连接部156，所述蓄势弹簧16的一端连接在所述第一弹簧连接部123上，另一端连接在所述第二弹簧连接部156上，且所述蓄势弹簧16靠近所述第二弹簧连接部156的部分位于所述容纳槽155内，其中，所述容纳槽155将所述蓄势弹簧16限制为朝向所述转轴122弯曲，这样在转动体15旋转时，蓄势弹簧16沿弧形路径伸缩。
本实施方式中，所述电涌保护模块1还包括壳体11，如图1和图2所示(并结合图10)，所述壳体11上设置有状态显示孔111；
所述承载架12上设置有第一状态指示部124，在所述转动体15位于所述第一位置时，所述状态显示孔111显示所述第一状态指示部124，指示电涌保护模块处于正常工作状态；所述转动件15上设置有第二状态指示部152，在所述转动体15转动至所述第二位置时，所述状态显示孔111显示所述第二状态指示部152，指示电涌保护模块处于失效状态。
具体的，所述第二状态指示部152设置在所述隔弧板154在径向方向上的外侧(以转轴122为圆心的径向方向)，且所述第二状态指示部152沿弧形伸出所述隔弧板154形成朝向所述转轴122弯曲的弧形条。
所述第一状态指示部124与所述状态显示孔111之间具有间隙，在所述转动体15转动至所述第二位置时，所述第二状态指示部152转动至进入所述间隙内，且对应于所述状态显示孔111，由此所述状态显示孔111显示所述第二状态显示部152。
根据本发明的另一方面，还提供一种电涌保护装置，如图11和图12所示，所述电涌保护装置包括底座2以及安装在所述底座2上的如上所述的电涌保护模块1；

本实施方式中，如图13-图15所示，所述遥信机构包括微动开关23、联动摆杆24、对应于每个所述电涌保护模块1设置的传动件25以及每个所述传动件25与所述底座2之间设置的弹簧26；其中，
所述微动开关25固定安装在所述底座2上，所述联动摆杆24可转动地安装在所述底座2上(微动开关25和联动摆杆24具体是安装在底座2的安装主体22上)，所述联动摆杆24包括用于触动所述微动开关23的按钮的触动部241以及对应每个所述传动件25设置的受力部242；
所述转动体15的朝向所述承载架12底端的一侧形成有限位面151，所述转动体15处于所述第一位置时，所述转动体15的所述限位面151压在所述传动件25上使得所述传动件25处于受压状态，所述弹簧26被压缩在所述传动件25与所述底座2之间，所述微动开关23发出所述第一状态信号，指示电涌保护装置处于正常状态；所述转动体15转动至所述第二位置时，所述传动件25脱离所述转动体15的压力，所述传动件25在所述弹簧26的弹力作用下移动，所述传动件25推动所对应的所述受力部242以使得所述联动摆杆24旋转，所述触动部241在旋转时触动所述微动开关23的按钮，所述微动开关23发出所述第二状态信号，以指示电涌保护装置处于失效状态。
优选地，在底座2上可设置遥信端子座3和连接于该遥信端子座3的遥信连接端子4，遥信端子座3与微动开关23连接，以通过遥信端子座3与遥信连接端子4对微动开关23所指示的信号进行远程传输。
具体的，如图15所示，本实施方式中的每个所述传动件15包括：
中间部251，所述中间部251设置为用于推动所述联动摆杆24的所述受力部242；
第一柱体252，所述第一柱体252位于所述中间部251的一侧，所述第一柱体252用于与所述脱扣机构联动；
第二柱体253，所述第二柱体253设置在中间部251的另一侧，所述弹簧26套在第二柱体253上，且弹簧26的一端顶在中间部251上，另一端顶在安装主体22上；
其中，所述转动体15处于所述第一位置时，所述转动体15的限位面151对第一柱体252施加压力，使得所述弹簧26处于压缩状态；所述转动体15处于所述第二位置时，所述第一柱体252脱离所述转动体15的压力，所述弹簧26驱动传动件25移动以使得所述中间部251推动联动摆杆24的受力部242，联动摆杆24旋转并按压微动开关23。
图18显示了底座2上安装有四个电涌保护模块1，图19显示了底座2的安装主体22上安装有联动摆杆24以及对应于四个电涌保护模块1的传动件25，联动摆杆24上设置有分别对应于四个传动件25的受力部242。
本发明提供的电涌保护装置中，其中任意一个电涌保护模块1失效，则联动摆杆24均会触动微动开关23，从而发出电涌保护装置失效的信号。
下面对本实施方式中的所述电涌保护装置的具体工作过程进行描述。
如图16和图17所示，遥信机构安装在底座2上时，传动件25的第一柱体252穿过底座2的上盖21以及电涌保护模块1中承载架12上的过孔126。
在电极引出件14与压敏电阻器13的第二电极132之间处于焊接状态时，转动体15处于第一位置，如图16所示的状态，此时，转动体15的限位面151压在传动件25的第一柱体252上，弹簧26在传动件25的压力作用下处于收缩状态，传动件25不对联动摆杆24施力，微动开关23没有受到联动摆杆24的压制，从而微动开关23处于指示电涌保护装置正常工作的状态；在压敏电阻器13发生劣化、短路等故障时，温度上升，使电极引出件14与压敏电阻器13的第二电极132之间的焊料熔化时，转动体15转动至第二位置，如图17所示，第一柱体252脱离转动体15的限位面151的限制，传动件25在弹簧26的弹力作用下向上移动，在上移过程中，传 动件25上的中间部251推动所对应的联动摆杆24上的受力部242，从而联动摆杆24转动，联动摆杆24的转动会使得触动部241按压微动开关23上的开关，改变微动开关23的状态，指示电涌保护装置处于无效状态，且该指示信号通过遥信端子座3和连接于遥信端子座3的遥信连接端子4实现远程传输，提醒维护人员及时对更换失效的电涌保护模块1。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
