摘要
决定电动机绕组绝缘寿命的基本因素是温度,目前温度保护在单相小容量电动机中应用较多,而在三相电动机中应用却很少.为此,我们设计了用蝶形过流过热保护器和埋入式过热保护器对三相电动机进行过热保护的方案.
Basic factor that decides insulating life of motor's winding is temperature. At present, temperature protection is used in small capacity single-phase motor. But it is rarely used at three-phase motor. For this reason, we have designed a plan that protects three-phase motor's ovperheat. It is made up of papilionaceous over current and over-heat protect ion equipment and coverd over-heat protect equipment.
