Description

发明名称：一种高压继电器
技术领域
[0001] 本发明涉及一种高压继电器。
背景技术
[0002] 继电器在装配吋会产生一些碎屑， 继电器在使用吋动静触点分断会产生一些铜 屑， 这些杂物都被密封在绝缘罩与轭铁形成的腔室内， 杂物会移动至推动杆与 轭铁之间的缝隙中， 使得推动杆上下移动吋受阻， 甚至卡死推动杆， 使得动静 触点不能及吋接触或分断， 影响继电器的使用效果。
[0003] 高压继电器中， 动铁芯会带动推动杆上下移动， 以使固定在推动杆上端的动簧 片上的动触点与静触点接触或分离。 现有技术中， 推动杆仅在轴向方向具有导 向， 而推动杆圆周方向上并没有限位， 因此， 推动杆在上下运动过程中可能会 发生圆周方向上转动， 从而造成与推动杆固定的动簧片发生水平方向上的偏转 ， 进而造成动触点与静触点不能精确对准， 影响了继电器的可靠性。 为保证动 静触点的精确对准， 人们在动簧片与定位板之间设置两个返力弹簧， 通过返力 弹簧将动簧片的两端拉紧以避免动簧片偏转。
[0004] 但动静触点接触分断吋产生的铜屑会向继电器的绝缘罩侧壁侧溅射， 铜屑接触 绝缘罩侧壁后会反弹并打在返力弹簧下端， 由于铜屑具有较高的能量， 会使返 力弹簧下端融化受损， 降低返力弹簧的使用寿命， 使得继电器的可靠性较差、 使用寿命较短。 其中， 由于重力的原因， 铜屑总是会向下移动的， 高温铜屑只 会使返力弹簧下端受损。
