AI Technical Summary
Technical Problem
[0002]10kV柱上真空断路器能实现分合、开断故障电流的功能，而操作机构是其中的重要部分，安装在机构上的分合闸线圈更是帮助断路器实现电动分合闸的主要零部件，但是由于断路器频繁操作、控制回路电压异常、线圈质量不佳或机构卡滞使线圈通电后电流持续过大，这些因素都有可能会造成线圈的损毁，而使断路器的正常运行受到影响
Benefits of technology
[0009]本实用新型设计了一种分合闸线圈的便捷更换结构，分闸线圈和合闸线圈安装在安装板上，便捷更换结构整体固定设置于断路器箱体内操作机构上，在箱体上对应位置开设可拆装的侧板盖，需要更换线圈时只需打开侧板盖，拆出安装板即可对有故障的分闸线圈或合闸线圈进行更换，拆装只需两个螺栓即可完成，既实现快捷更换，又对操作机构的改动微小，成本低廉；合闸线圈对应位置设置推板，以实现合闸线圈与合闸挡块之间的合闸操作，解决了原合闸线圈安装操作的问题，适合大规模推广应用。
