海外项目对低压配电柜的分隔要求

Introduction of the Separation Requirements of Low Voltage Switchgear in Overseas Projects

通过对IEC 61439标准中低压配电柜4b分隔的介绍,阐述了海外项目对低压配电柜内部分隔的要求。通过图片的形式,介绍了4b分隔与其他分隔形式的不同点。最后,介绍了海外项目对低压配电柜的认证要求和配电柜的设计技巧。

The form 4 b of low voltage switchgear in IEC 61439 standard was introduced, and the requirements for internal separation of low-voltage switchgear in overseas projects were described. And through the pictures, the differences between form 4 b and other forms of separation were introduced. At the same time, the certification requirements of overseas projects for low-voltage switchgear were also introduced,as well as the design skills of switchgear.
