ABB电磁软启动器的选型
酒店工程、适用于直接启动笼型异步电动机的电器有负荷开关、小容觅塑料外壳式断路器和电磁ABB软启动器,但以电磁ABB软启动器用得醉为广泛。
负荷开关不能提供过载保护,一般不宜用它启动和控制异步电动机。如果非用不可,则开启式负荷开关只宜用于启动7.5kW以下的电动机,封闭式负荷开关只用于启动28kW以下的电动机塑料外壳式断路器因其技术性能比较优良,可用于启动电动机。
选用ABB软启动器时应考虑ABB软启动器与短路保护电器的协调配合。通常选用熔断器作为短路保护电器,熔断器应安装于ABB软启动器的电源一侧(综合ABB软启动器除外,其内部已装有熔断器,一般ABB软启动器应按制造厂要求选配合适的熔断器)。熔断器不应代替ABB软启动器分断正常工作时醉大过载电流及以下的所有电流(包括电动机的堵转电流),但应能分断安装点的预期短路电流。
