Description

一种可同时切断零线和火线的磁保持继电器 【技术领域】
本发明属于继电器技术领域，具体涉及一种可同时切断零线和火线的磁保持继电器。
【背景技术】
继电器是具有隔离功能的自动开关元件，广泛应用于遥控、遥测、通讯、自动控制、机电一体化及电力电子设备中，是最重要的控制元件之一。磁保持继电器是近几年发展起来的一种新型继电器，也是一种自动开关。和其他电磁继电器一样，对电路起着自动接通和切断作用。所不同的是，磁保持继电器的常闭或常开状态完全是依赖永久磁钢的作用，其开关状态的转换是靠一定宽度的脉冲电信号触发而完成的。当继电器的触点需要开或合状态时，只需要用正(反)直流脉冲电压激励线圈，继电器在瞬间就完成了开与合的状态转换。通常触点处于保持状态时，线圈不需要继续通电，仅靠永久磁铁的磁力就能维持继电器的状态不变。随着继电器应用需求的不断扩大，大功率继电器变得炙手可热。目前普通单回路磁保持继电器仅能切断其中一路相线，在使用过程中存在较大的安全隐患，而采用继电器组合的方式虽然能够实现大功率以及避免上述安全隐患，但也带来了成本增加以及使用不方便等问题。因此，如何通过优化设计，研究开发大功率且安全实用的继电器成了一种需求趋势。
【发明内容】
本发明的目的在于提供一种可同时切断零线和火线的磁保持继电器，以解决目前磁保持继电器功率小、动作不灵活、使用不安全等问题。
为解决以上技术问题，本发明采用以下技术方案：
一种可同时切断零线和火线的磁保持继电器，包括：壳体，设置在壳体内的磁路系统、动接触部分、静接触部分，所述壳体包括上盖和外壳，所述动接触部分和所述静接触部分分别为零线和火线连接的部分，形成一个可以同时切断零线 与火线的控制回路；所述磁路系统包括带有凸缘的支架、一加强型的电磁组件、推动片，所述加强型的电磁组件包括设置于二轭铁一头之间的线圈架，以及设置于二轭铁另一头之间的衔铁片；所述磁路系统通过一个推动片的推动力来控制动接触部分的开合，以同时控制零线和火线的断开与闭合。
优选地，所述上盖和所述外壳上设置有出线孔，用于引出检测线。
再优选地，所述出线孔设置在所述上盖的上表面。
更优选地，所述出线孔还可以设置在所述外壳的侧面。
优选地，所述凸缘横向设置于所述支架上。
优选地，所述凸缘与所述外壳内壁刚好接触。
优选地，所述凸缘为2个。
优选地，所述轭铁为加长加宽加厚型。
优选地，所述衔铁片为加长加厚型。
优选地，所述线圈架为加长加宽型。
与现有技术相比，本发明具有以下有益效果：
本发明提供了一种可同时切断零线和火线的磁保持继电器，该继电器壳体上盖的表面与外壳的侧面均可以通过出线孔引出检测线，使用更方便；磁路系统采用带凸缘的支架以及加强的电磁组件，不但可以避免外壳内壁对继电器活动零件的干扰、增强继电器动作的灵活性，还能增大继电器的功率，通过同时切断控制回路中的火线与零线，极大地提高了使用安全性能。

一种可同时切断零线和火线的磁保持继电器，包括：壳体，设置在壳体内的磁路系统5、动接触部分4、静接触部分3，所述壳体包括上盖2和外壳1，所述上盖2和所述外壳1上设置有出线孔21，所述出线孔21设置在所述上盖2的上表面和所述外壳1的侧面，用于引出检测线，该出线孔21的设计方式适用于不同条件下的使用，方便实用；所述动接触部分4和所述静接触部分3分别为零线和火线连接的部分，形成一个可以同时切断零线与火线的控制回路；所述磁路系统5包括带有凸缘511的支架51、一加强型的电磁组件、推动片52，所述凸缘511横向设置于所述支架51上，其数量为2个，且凸缘511与所述外壳1内壁刚好接触，以避免外壳1内壁对继电器活动零件的干扰，起到支撑的作用，使继电器动作更加灵活，而不带凸缘的支架的磁保持继电器，其支架与外壳内壁相距较远，没有起到支撑作用；所述加强型的电磁组件包括设置于二轭铁53一头之间的线圈架55，以及设置于二轭铁53另一头之间的衔铁片54，所述轭铁53为加长加宽加厚型，所述衔铁片54为加长加厚型，所述线圈架55为加长加宽型，该加强模式有效提高了双路磁保持继电器的功率，实现了大功率的目标；所述磁路系统5通过一个推动片52的推动力来控制动接触部分4的开合，以同时控制零线和火线的断开与闭合，从而确保继电器使用的安全性。
与普通磁保持继电器相比，本发明的加强型的电磁组件有以下区别特征：
