高压断路器中的弹簧操动机构刘唯2015.4摘要：本文讨论了断路器操动机构的功能，总结并比对了目前主流弹簧操动机构的实现方式，也介绍了各种结构的优缺点。

列举了断路器上弹簧机构的各种布局方式，从控制，安全，维护及发展的角度谈了个人看法。

文中没有计算，没有公式，略显没有深度，请高手一笑而过。

文中试图将千差万别的机械结构进行分类，会有遗漏，但终归是一次尝试。

也试图将其优缺点做一比较，必不完全，但肯定会有些说法。

有些机构，并不能完全理解其博大精深，不正之处，也还望请指正。

Esimprescindible que también desconecte el enchufe de la red.• Se saca el portafusible en la parte traserade la fuente, utilizando un destornillador plano (ver Fig. 1) • Se fija el destornillador del lado del enchufepara aparato frio. • Se remplaza el fusible y se vuelve a insertar el portafuibles.Fig. 1 Reemplazo de fusibles5. Mantenimiento, limpieza, desecho • El aparato debe permanecer en un lugarlimpio, seco y libre de polvo. • Antes de la limpieza el aparato se separadel suministro de corriente. • No se debe usar ningún elemento agresivoni disolventes para limpiar el aparato. • Para limpiarlo se utiliza un trapo suavehúmedo. • El embalaje se desecha en los lugareslocales para reciclaje. •En caso de que el propio aparato se deba desechar como chatarra, no se debe deponer entre los desechos domésticos normales. Se deben cumplir las prescripciones locales para el desecho de chatarra eléctrica.6.
