【技术实现步骤摘要】
弹簧操动机构独立双分闸电磁铁
本技术涉及高压电力设备
,特别是一种应用于110KV及220KV断路器的弹簧操动机构独立双分闸电磁铁。
技术介绍
电网要求110kV及220kV断路器所配用的弹簧操动机构,应配置具有可替换性分闸电磁铁(即在主分线圈出现故障不能使用的情况下,备分线圈须接入分闸回路实现断路器的分闸操作),以增加断路器分闸操作的保险系数;而且主分、备分分闸时间应该相同,但在实际应用中,弹簧操动机构所使用的均为模糊概念上的分闸电磁铁,因为是两只线圈共用一套铁芯,所以在主分线圈骨架损坏变形引起卡滞时,备分线圈仍无法执行分闸操作;且在电磁铁气隙相同的条件下,主分、备分线圈的分闸时间相差较大,这样就对断路器的长期运行带来安全隐患,无法实现电磁铁相互独立的要求。
技术实现思路
本技术的目的是提供一种在保证弹簧操动机构性能的前提下,实现分闸电磁铁的独立双分,符合电网所规定的弹簧操动机构独立双分闸电磁铁。本技术是这样实现的,它包括分闸掣子、复位弹簧、合闸保持掣子、分闸弹簧、拐臂、单铁心单线圈电磁铁、备份单铁心单线圈电磁铁、电磁铁安装板及压板,分闸掣子与合闸保持掣子相配合,合闸保持掣子与拐臂相配合,在分闸挚子上设置有两个触发点,单铁心单线圈电磁铁、备份单铁心单线圈电磁铁分别做为主分线圈电磁铁,备分线圈电磁铁,单铁心单线圈电磁铁与备份单铁心单线圈电磁铁垂直分布。本技术采用了力矩相等及线圈电磁力互不干涉的原则进行设计,在确定安装两个垂直分布的单铁芯单线圈电磁铁条件下,使用具有两个触发点的同一个分闸掣子与两个电磁铁配合安装,既可实现独立双分的要求,也可做到电磁力互不干 ...
