Description

电涌保护装置 技术领域
本发明涉及电路保护设备, 更具体地说, 涉及一种适用于低压配电系 统用的电涌保护器, 该电涌保护器包含带有指示功能的故障保护脱离装置 和远程脱扣报警装置, 以便对多个电涌保护模块的工作状况进行准确监控。 背景技术
根据现有认识可知, 由雷电引起的电力系统或信号系统的过电压有两 种途径, 一种是通过地电位反击、 雷击线路等途径直接作用于电气系统并 破坏电力设备和其他电器; 另一种是云闪、 雷击大地或雷击其他建筑物通 过耦合途径, 间接作用于电气系统并破坏电力设备和其他电器。
对由雷电引起并通过这两种途径生成的过电压, 应采用过电压保护装 置或措施进行保护。 过电压保护即为当电压超过预定最大值时, 使被保护 设备电压被限制到可以接受的范围内的一种保护方式。 其中, 避雷器、 击 穿保护器、 接地装置等是常用的过电压保护装置。
在低压系统中, 对这样的过电压, 这个行业领域的技术人员较为常见 地使用电涌保护器 SPD(Surge Protective Device)进行保护。 根据 IEC的 标准 IEC 62305-1 与标准 IEC 62305-4 中通过对雷电保护区域 LPZ(Lightning Protection Zone)划分保护区域以及对电涌保护器进行选型 使用来构建完整的防雷体系。
问题在于, 电涌保护器在其使用过程中会慢慢劣化。 如果尚在使用中 的电涌保护器发生劣化的情况, 而使用该产品的用户对此情况不知情, 则 可能发生以下两种情况:
1 )电涌保护器未安装脱扣与指示装置, 于劣化后未脱扣, 将原本被保 护的设备短路;
2 ) 电涌保护器安装了脱扣装置但无指示装置, 在发生劣化后自脱扣。 但使用该产品的用户由于无法得知电涌保护器状态没有及时更换电涌保护 器。 在下一次过电压来临时, 被保护设备缺乏过电压保护被过电压打坏。
在现有的公知技术中, 为了解决这问题, 一般通用的方法是在电涌保 护器中附加安装一个带劣化脱扣和状态报警功能的装置。 这样所述的一个 带劣化脱扣和状态 4艮警功能的装置, 可具体地分为两个部分, 现场脱扣 4艮 警装置与远程脱扣报警装置。
目前, 对大多数电涌保护器, 仅包含现场脱扣报警装置。
国内市场上普遍的电涌保护器产品中仅包含现场脱扣报警装置。 该装 置是这样设置与构成的, 通过软导线与弹簧元件相连, 焊接点在软导线与 电涌保护器泄电器电极之一之间实现。 如此带来的缺陷是:
1 )软导线与泄电器电极之间的电气连接工艺复杂;
2 )软导线其本质是金属丝绕线, 处于带有高温的泄电器周围会加速其 材质老化, 从而影响现场脱扣报警装置的动作性能。
中国专利 CN 101485056A揭示了一种用于电和机械的接纳至少一个 可插入到基座件中的过电压放电器的基座件。 这项技术公开了一项了远程 脱扣报警装置。 其技术特征在于, 设置这样一种结构, 以斜向平面与斜向 平面契合运动的方式, 将模块劣化情况控制的滑块的竖直上下运动变为键 式推杆水平运动,将多个滑块的上下运动转化为单一键式推杆的水平运动, 从而实现了多级模块的远程遥信劣化指示。 由于该结构需要多个弹簧元件 与对应多个滑块配合, 从而推动对应的多个辅助推杆。
中国专利 CN 100550566C揭示了一种过电压保护装置。其包含了现场 脱扣报警装置与远程脱扣报警装置。 在模块中设置这样一种结构, 弯曲的 柔性印制线路板与弹簧元件相连, 柔性印制线路板上带颜色显示。 其中在 焊接点处实现的焊接连接在泄电器电极和柔性印刷线路板的一个区域之间 实现。 同时, 在底座中设置这样一种结构, 通过在底座较中心位置设置支 点, 在支点上架设可两边翻动的平板, 以及与平板两端的弹簧元件构成一 个杠杆机构。这样的结构利用一块平板可实现对多个模块劣化情况的监控。 发明内容

图 5 揭示了具有第二实施例的结构的远程报警装置。 具体实施方式
本发明的电涌保护器的设计思路如下: 将电涌保护器分为具有电涌保 护模块以及相应的安装底座两部分, 这两部分结构能够相互分离, 如此可 使得该电涌保护器具有在线维护的功能, 其中的电涌保护模块包括带有开 关型保护功能的模块和带有限压型保护功能的模块, 这两者都具有独立的 适合其结构的带有指示功能的故障保护脱离装置, 并且与相应的安装底座 中具有远程报警装置关联。 开关型电涌保护功能的模块和限压型电涌保护 功能的模块可零距离直接配合使用。
总的来说,本发明提出的电涌保护器除了具有基本的电涌保护功能外, 还能够具有自显示工作状态和故障脱离自保护功能, 此外还可通过远程报 警装置将自身的工作状态信息远程传输到监控室, 以确保工作人员随时掌 控电涌保护器装置对被系统的保护情况。 为了实现这个目的, 本发明的电涌保护器的结构可以实现如下: 带有 指示功能的故障保护脱离装置的开关型电涌保护模块及限压型电涌保护模 块、 以及具有远程报警装置的底座。
带有指示功能的故障保护脱离装置安装在开关型电涌保护模块以及限 压型电涌保护模块内, 故障保护脱离装置包含可旋转的导电片、 通过窗口 显示工作状态的色带指示器、 故障保护脱离驱动以及色带指示器变化动作 的储能弹簧三个主要部分。 其中, 带有指示功能的故障保护脱离装置如此 设置和构成: 色带指示器固定安装在可旋转的导电片一端并随着导电片不 同的状态变化而变化, 导电片的长脚端延伸到开关型电涌保护模块的下方 并通过与底座中关联顶杆同心的遥信驱动圆孔与外界相连, 将通孔变成遥 信驱动盲孔。 限压型电涌保护模块中的带有指示的故障保护脱离装置适合 限压型电涌保护模块的结构, 与开关型电涌保护模块的故障保护脱离装置 不同; 同时, 限压型电涌保护模块同样具有类似遥信驱动通孔与遥信驱动 盲孔的两种位置。
该带有指示功能的故障保护脱离装置有不同的两种位置状态, 当开关 型电涌保护模块正常工作时, 带有指示功能的故障保护脱离装置处于正常 状态 (A 状态) 中, 该状态下, 可旋转运动的导电片一端与开关型电涌保 护模块的触发电路中压敏电阻 ( MOV ) 引线的一端焊接在一起并固定在此 位置, 该焊接可通过特定温度的低温焊锡完成, 此时, 通过开关型电涌保 护模块状态窗口观察到的色带指示器显示着代表正常工作状态的绿色指 示, 储能弹簧处于储能状态, A 状态下的开关型电涌保护模块能够持续对 系统进行电涌保护。
当开关型电涌保护模块出现故障时, 可旋转运动的导电片一端与开关 型电涌保护模块的触发电路中压敏电阻 ( MOV ) 引线的一端焊接端会出现 超过预定的温度, 如此会使得带有指示功能的故障保护脱离装置处于故障 状态 ( B 状态) 中, 此时, 以导电片的中心孔与插入到放电模块内的电极 轴作为支点、 可旋转运动的导电片一端与开关型电涌保护模块的触发电路 中压敏电阻(MOV ) 引线的一端焊接端在储能弹簧的共同作用下分离, 同 时可以观察到开关型电涌保护模块状态窗口显示着代表故障工作状态的红 色指示, 储能弹簧也处于释能状态, 导电片的长脚端按照旋转轨迹颜色弧 形凹槽运动并使得位于开关型电涌保护模块底部的盲孔变成通孔, 在这种 状态下的开关型电涌保护模块脱离了被保护系统并不在具有电涌保护能 力。 此外, 作为支点的导电片的中心孔与插入到放电模块内的电极轴为导 电性连接; 带有指示功能的故障保护脱离装置中的导电片可通过至少一个 柔性的 PVC、 不干胶绝缘带构成。
根据一种设计方案, 底座中设置了与模块的 A、 B 两种状态所对应的 远程报警开关, 并且该远程报警开关通过一套柔性操作机构与至少一个模 块进行关联, 其中, 报警开关与柔性操作机构形成远程报警装置。 此种方 案下, 报警信号传输线路与当柔性操作带一体化制造, 安装在底座上满载 的模块且都处于 A状态时, 开关型电涌保护模块内的导电片长脚端克服关 联顶杆和驱动弹簧使得远程报警装置也处于对应的常规状态, 此时远程报 警开关和柔性操作带都处于自由位置, 关联顶杆与驱动弹簧被位于开关型 电涌保护模块内的导电片长脚端压下处于蓄能位置。 当安装底座上缺少模 块或模块安装不到位或至少一个模块处于 B状态时, 远程报警装置与之相 对应的关联顶杆在驱动弹簧作用下作直线, 通过柔性操作机构连接可将顶 杆的直线运动转化到与顶杆运动方向成一定角度的其它方向的直线运动, 并驱动远程报警开关进行信号切换通过一体化的报警信号传输线路发出信 号, 以提醒远方的监控室及时了解产品的工作状态, 此时底座中的远程报 警装置处于故障状态。 限压型电涌保护模块中驱动通孔与遥信驱动盲孔的 两种位置同样可关联底座中的关联顶杆, 并对限压型电涌保护模块的工作 状态进行监控并传递状态信息。 采用柔性线路板作为报警信号传输线路和 柔性操作带一体化的制作材料是优选的方案。
根据另一种设计方案, 带有指示功能的故障保护脱离装置如此设置和 构成: 色带指示器固定安装在可旋转的导电片一端并随着导电片不同的状 态变化而变化, 可旋转的导电片通过一根具有电气连接功能的内部电极延 伸出的圆台棒作为旋转轴旋转, 其中, 圆台棒与内部电极成一体化设计, 也可以是利用圆棒形电极作为旋转轴。 同时, 远程报警装置如此设置和构 成: 远程报警装置包括远程报警开关、 报警信号传输线路及信号接线端口、 柔性操作带、 至少一个驱动弹簧和至少一个关联顶杆, 其中柔性操作带将 至少一个关联顶杆与远程报警开关进行连接, 并能够对至少一个关联顶杆 从常规状态移动到故障状态时进行响应。 在这种方案中, 本发明技术方案 工艺安装措施简单, 可实现单一零件多种用途, 有利于产品减少使用零件 数量, 降低成本。 工作原理与前一种方案类似。

导电片 113的第二端是长脚端, 长脚端伸入内壳体 116的弧形凹槽中 并固定, 储能弹簧 114的第二端固定到内壳体 116的圆形凸台上, 色带指 示器 115为柔性, 色带指示器 115具有颜色区分部分, 颜色区分部分贴合 所述上端面 108并随上端面的弧形弯曲。 色带指示器 115的颜色区分部分 包括第一色区 121和第二色区 122, 第一色区 121和第二色区 122具有不 同的颜色, 色带指示窗 112每次只显示第一色区 121 与第二色区 122的其 中之一。

这样一个带劣化脱扣和状态报警功能的装置分为带有指示功能的故障 保护脱离装置 105与远程报警装置 106。 带有指示功能的故障保护脱离装 置 105被设置于有开关型保护模块(I级) 102、 限压型保护模块(II级) 103 , 远程报警装置 106被设置于相应的底座 104中。
在 I+II—体化电涌保护器 101 中, 在底座上设置了一个共同的远程报 警开关 107作为故障通报的信号发生器。 该远程报警开关 107可通过被设 置与底座 104中的远程报警装置 106来操作。远程报警开关 107的可通过 一个电导线, 例如一个数据总线或者通过无线电传输到监控层。 为了在现场监控电涌保护器的状态, 在开关型保护模块 102的上端曲 面 108, 也就是与带有遥信驱动圆孔 109的下端面 110相背的端面上具有 一个腰形或矩形窗口 111, 在腰形或矩形窗口 111优选地可设置一透明的 薄片, 形成可直接观察的色带指示窗 112。 如图 2所示, 色带指示器 115 是和远程报警装置 106由指示功能的故障保护脱离装置 105的机械结构同 步控制的。
带有指示功能的故障保护脱离装置 105与远程报警装置 106的联动。 其中, 如前文所述, 可旋转的导电片 113、 色带指示窗 112以及提供故障 保护脱离装置 105驱动力与引导色带指示器 115变化动作的储能弹簧 114 属于现故障保护脱离装置 105。如图 3a和图 3b所示,可旋转的导电片 113 的中心孔与内壳体 116中心孔中心对齐, 并用一才艮圆棒形电极 117插入固 定, 使可旋转的导电片 113与内部电极导电连接。 可旋转的导电片 113的 一端与柔性的色带指示器 115以及储能弹簧 114固定安装, 储能弹簧 114 的另一端鈎在开关型保护模块 102的内壳体 116突起的圆形凸台上。 可旋 转的导电片 113的另一端即长脚端伸入内壳体 116上的弧形凹槽。 其中, 柔性的色带指示器 115与可旋转的导电片 113相连并随其同步运动, 其带 有颜色区分的部分贴合并沿内壳体 116上端面的弧形端面 108 自然弯曲。
其中, 可旋转的导电片 13如图 3a和图 3b所示, 具有一个焊接连接 区域 119。 该焊接连接区域 119在焊接点与放电模块的触发回路的压敏电 阻电极 120之间,带有导电作用的可旋转的导电片 113与压敏电阻电极 120 在这个区域内实现电气连接。 对这样的焊接连接区域 119, 本发明的技术 方案要求, 为了控制开关型保护模块 102热脱扣的效果, 要求焊接区域的 低温焊锡在所规定的温度阀值点熔焊, 保证电气连接断开。
根据图 3a和图 3b所示的实例, 柔性的色带指示器 115具有两个不同 颜色的色区, 第一色区 121和第二色区 122。 其中, 如图 3a和图 3b所示, 按照故障保护脱离装置 105 的状态, 只有一个色区可在开关型保护模块 102的上端曲面 108的色带指示窗 112被显示。 其中, 如前文所述, 当开 关型保护模块 102正常工作时,即故障保护脱离装置 105处于正常状态( A 状态) 时, 在色带指示窗 1 12的位置可观察到第一色区 121 (例如绿色); 当开关型保护模块 102出现故障时, 即故障保护脱离装置 105处于故障状 态 ( B状态) 时, 在色带指示窗 1 12的位置可观察到第二色区 122 (例如 红色) 。
这样的一个带有指示功能的故障保护脱离装置 105存在两种状态, 即 正常状态 (A状态) 与故障状态 ( B状态) 。 当开关型保护模块 102正常 工作时, 带有指示功能的故障保护脱离装置 105处于 A状态。 在这种状态 下, 可旋转的导电片 1 13的一端与压敏电阻电极 120通过低温焊锡固定, 此时, 储能弹簧 1 14处于储能状态。 当开关型保护模块 102出现故障时, 即带有指示功能的故障保护脱离装置 105处于 B状态。 在这种状态下, 焊 接连接区域 1 19的低温焊接熔焊,可旋转的导电片 1 13与压敏电阻电极 120 相互之间不再固定。此时, 以圆棒形电极 1 17为支点,可旋转的导电片 1 13 与开关型保护模块的触发回路中的压敏电阻电极 120的一端焊接端在储能 弹簧 1 14的作用下分离。 此时, 储能弹簧 1 14处于释能状态。 在图 3a和 图 3b所示的实施例中, 可旋转的导电片 1 13 的长脚端与开关型保护模块 102以及内壳体 1 16的下端面 1 10的遥信驱动圆孔 109形成了一个开关通 道结构 123。 该开关通道结构 123是如此构成和设置的: 带有指示功能的 故障保护脱离装置 105处于 A状态时,开关通道结构 123被控制地关闭在 开关型保护模块 102的内壳体 1 16上的供关联顶杆 125运动的通道 124。 此时,遥信驱动圆孔 109为盲孔状态。相对地,在 B状态中打开该通道 124。 此时, 遥信驱动圆孔 109为通孔状态。 通过将开关型电涌保护模块 102插 入底座 104 时, 这样的设置可保证现场带指示功能的故障保护脱离装置 105与远程 4艮警装置 106的联动。在图 3a和图 3b所示的电涌保护器 101, 带指示功能的故障保护脱离装置 105在 A状态时关闭通道 124 , 使关联顶 杆 125克服驱动弹簧 126的弹力被压下。 相反的是, 带指示功能的故障保 护脱离装置 105在 B状态时, 通道 124不再被开关通道结构 123关闭, 关 联顶杆 125受到驱动弹簧 126的弹力通过通道 124沿着通道 124的方向运 动, 驱动远程 4艮警装置 106, 实现联动。
在图 1 -图 5所示的实施例中,远程报警装置 106是如此设置和构成的, 包括: 远程报警开关 107、 报警信号传输线路 128及信号接线端口 129、 柔性操作带 127, 至少一个关联顶杆 125与至少一个驱动弹簧 126。 由于 带指示功能的故障保护脱离装置 105与远程报警装置 106是联动的, 对应 地, 远程报警装置 106也存在正常状态( A状态 )和故障状态( B状态 )。 其中, 本发明的一个优选的构成是: 在柔性操作带 127的几个位置涂覆金 属层, 以保证硬度及强度。 在图 4a和图 4b所示的实施例中, 从 A状态变 化到 B状态的过程中,柔性操作带 127在设置在底座 104的运动槽中由关 联顶杆 125控制。 当 A状态时, 开关型保护模块 102内的可旋转的导电片 的长脚端克服关联顶杆 125和驱动弹簧 126使得远程报警装置 106也处于 对应的常规状态, 此时远程艮警开关 107和柔性操作带 127都处于自由位 置, 关联顶杆 125与驱动弹簧 126处于蓄能位置。 而当 B状态时, 远程报 警装置 106与至相对应的关联顶杆 125在驱动弹簧 126的弹性作用下弹 起, 通过柔性操作机构 132连接可将关联顶杆 125的直线运动转化为与关 联顶杆 125运动方向成一定角度的其它方向的直线运动。
按照第一种方案,柔性操作带 127与报警信号传输线路 128—体成型, 构成柔性操作机构 132。 在这种方案中, 柔性操作带 127这样变化: 使柔 性操作带 127涂覆了金属层的部分挤压远程报警开关 107。 在该方案中, 柔性操作机构 132 (包括柔性操作带 127与报警信号传输线路 128 ) 既承 担了触发微动开关的任务, 又带有传输信号的功能。
按照第二种方案, 如图 5所示, 远程报警装置 106中的柔性操作机构 132也是由柔性操作带 127与报警信号传输线路 128组成, 但柔性操作带 127与报警信号传输线路 128不是一体成型。 即柔性操作带 127不需具备 传输信号的功能。 这种情况中的柔性操作带 127可选择非 PCB FR-4板材 的其他带有强度的材料。 正如上文所述, 根据发明优选的劣化报警装置, 本发明的结构特点使 得有多个开关型保护模块 ( I级) 102或限压型保护模块 ( I I级) 103插入 底座 104时, 也可保证稳定的脱扣 4艮警动作。
本发明的电涌保护器安装措施简单, 可实现单一零件多种用途, 有利 于产品减少使用零件数量, 降低成本。 开关型电涌保护模块内带有指示功 能的故障保护脱离装置, 采用了旋转接触结构, 作为运动的动、 静导体连 接方式实现故障保护脱离工作。 安装在底座中的远程报警开关通过柔性操 作带完成对多个模块的工作状态同时进行监控的目的。
上述实施例是提供给熟悉本领域内的人员来实现或使用本发明的, 熟 悉本领域的人员可在不脱离本发明的发明思想的情况下, 对上述实施例做 出种种修改或变化, 因而本发明的保护范围并不被上述实施例所限, 而应 该是符合权利要求书提到的创新性特征的最大范围。
