【经验】使用Littelfuse机械式断路开关满足紧急停止、高电流控制电力系统的稳定运行
目前，触摸屏和薄膜开关具有较好的可视性和外观，适用于体积较小的薄型控制面板。然而，在一些强调强调安全性、易操作性、高电流的切换、上电可知配置以及稳健性的应用场合，机械开关仍然发挥着重要作用，但设计师需要谨慎选择。有许多类型的机械开关在形状，样式，尺寸，功能，功率和机械性能方面存在差异。本文将分享电池断路开关的相关设计经验，帮助设计人员对此类机械式开关的选择参数进行分类，从而更好地应用此类机械式开关设备。
设计者在选择机械开关之前，首要任务是要明确系统的要求。要找到适合应用的机械开关，必须要找到符合人体工程学和物理需求的开关外形，然后选择符合外形尺寸的适当电气和环境规格的开关。现主要分析紧急停止场合和高电流控制场合的机械式开关的应用。
紧急停止应用场合：
“紧急停止开关”是一个很典型的应用案例。在许多工业系统中，监管要求其必须要有一个大的红色或橙色按钮，附近通常会标记有大型的、醒目可读的“紧急停止”字样。此按钮必须处于明显且易于触发的位置，必须易于触发，并且必须有明确的触觉反馈以指示切换功能已完成。在某些工业环境中，不符合设计标准可能会影响设备的安全、稳健运行。
这种应用的优秀解决方案是来自LITTELFUSE的08080100系列断路开关。这是一款专门为保护电池应用安全而设计的断路开关。该产品具有一个熟悉的大圆锥形蘑菇形按钮，操作人员可在紧急情况下快速推送至关闭操作，重要的是，其具有一个可以逆时针旋转的键，旋转到OFF位置时会听到“咔哒”声，给操作人员良好的触觉反馈。同时，其旋钮顶部具有透明窗口，转动旋钮时，可以通过旋钮顶部的窗口查看开关状态，以确保旋钮状态。

Littelfuse的08080100可以处理高达150安培和24V的电池电压，具有高度可见的红色手柄，专为高可靠性紧急断路操作而设计；开关状态指示被设计到了旋钮的顶部，可为连接提供良好的视觉确认。支持IP65的防水防尘等级，适用于大多数恶劣的工业环境。08080100电池断路开关直径为60.5毫米（mm），足以用于工业控制面板，并且仍然足够小，可以在手持控制盒中实现。
要安装08080100电池断路开关，首先要确保开关所在的安装深度间隙，并钻一个安装孔。然后将08080100开关放入安装孔并使用相关的安装环螺母将其固定，需注意其推荐的螺栓紧固力矩为20±2 Nm。详细安装尺寸请参照图2。

高电流控制场合：
在有些场合，需要对电压和电流进行简单、严格的控制。对于用于执行高电流控制的软薄膜开关，由于需要接口电路，无形中使操作变得复杂化，尤其是如果对于不依赖于其他系统的控制，就没有必要使用此类软薄膜开关。对于这些情况，旋钮式的开关可以提供高可靠性的电压和电流的安全控制。例如，Littelfuse生产制造的功能强大的75920主电池断路开关（图3）。它可以处理400安培的连续电流。
图3 Littelfuse的75920系列主电池断路开关实物图
75920系列安装在间距35mm左右的两个圆形孔中。虽然此类断路开关易于使用，但安装应用中最困难的部分可能是为其创建两个相邻的圆形孔以便卡入。一种常见的技术是使用略小于孔宽度的钻头（孔径为标准的主断开开关孔径，可参照图4）。首先用铅笔画出圆形孔，然后在面板上钻两个相邻的孔，注意不要在铅笔线外面。接下来，使用金属工具钻孔，同时去除任何锐边，以免伤害安装人员。
图4 Littelfuse的75920系列主电池断路开关机械尺寸图
75920系列可用于恶劣的工业环境，其工作温度范围为-40至+ 85°C，具有IP68的防护等级；采用铜作为触点，接触电阻极低，可最大限度地降低大电流流过时的热量。在处理高电流开关操作时，请确保将每个连接分开以避免意外短路。75920采用具有醒目红色的优质塑料旋钮，具有极好的绝缘性，通过物理分离简化这一过程。另外，虽然强烈建议不要布线热端子，但有时在生产环境中无法避免，即使75920可以减少热接线过程中发生事故的可能性，但也请采取安全预防措施，包括戴上绝缘手套等。
结论：
机械式断路开关适用于某些特殊情况，具有高电流控制，安全性，易于操作等优势。机械开关有很多选择，正确的选择可以让设计师和最终客户高枕无忧。
