150 kV屋外配电装置最小安全净距的计算分析

摘要

Taking 150 kV outdoor power distribution equipment as an example, this paper discusses the cal-culation of minimum safety net distance of 150 kV outdoor power distribution equipment. Moreover, the paper suggests determining dry-arc distance of bushing during ordering outdoor HV equipment, providing reliable and reasonable type selection support for non-standard voltage class outdoor power distribution equipment de-sign and parameter selection in the future.%以150 kV屋外配电装置为例，探讨了屋外高压配电装置最小安全净距的计算取值方法。此外，提出屋外高压设备订货时应确定套管干弧距离这个重要参数的建议，为今后非标电压等级屋外配电装置设计及设备参数选择，提供了可靠合理的选型支持。
