为什么高原地区不能使用电机？

Publish Time: 04/26 2025Author: 网站编辑

高原地区的主要特点是

海拔高度对电机的温升、电机电晕（高压电机）和直流电机的换向都有不利影响。应注意以下三个方面：

高原电机是指海拔高于 1000 米的电机。根据国家行业标准 JB/T7573-94《高原环境条件下电机产品通用技术条件》，高原电机分为不超过 2000 米、3000 米、4000 米、5000 米等多个等级。

高原电机在高海拔地区运行，由于气压低，散热条件差，损耗会增大，运行效率会降低。因此，同样的，在不同海拔高度运行的电机，其额定电磁负荷和散热设计是不同的。对于非高海拔规格的电机，最好适当降低负载。否则会影响电机的寿命和性能，甚至在短时间内烧毁。

由于高原的特性会给电机的运行带来以下不利影响，因此在设计和制造时应采取相应的措施：
