园田变屋外配电装置间隔宽度设计值的探讨

Discussion about Yuantian Substation Outdoor Switching Devices Spacing Design

龙岩园田变电站110,220kV屋外配电装置间隔宽度比设计规范规定值小1000mm,减少站址占地面积约700m2。经过2年多的运行、检修实践,未出现异常。这说明园田变电站间隔宽度,在采取一定措施后,能满足运行、检修的安全要求,可作为站址场地紧张变电站的典型设计的推荐值。

The spacing distance of 110, 220 kV outdoor switching equipments in Tianyuan substation is 1,000 mm shorter than the value specified in design criterions, resulting in a smaller land usage of 700 m^2. After two years＇ operation and maintenance, there is no abnormity, which shows that having taken certain measures, the spacing distance meets operation and maintenance requirements, and can be recommended as typical design value for substations with limited field.
