摘要

550 kV线路融冰开关安装在户外

当高压输电线路需进行融冰处理时

融冰开关很可能也处于覆冰状态

因此满足不同工况的平衡性能设计非常重要。根据融冰开关技术参数要求

对550 kV大容量融冰开关的结构进行设计

并在此基础上对融冰开关不同工况下的平衡性能进行设计与校核。试验结果表明

该550 kV大电流融冰开关的平衡性能满足正常操作及20 mm厚度覆冰工况下的操作要求

具有普遍适用性。

Abstract

The ice melting disconnector of 550 kV line is installed outdoors. When the high-voltage transmission line needs ice melting treatment

the ice melting disconnector is also likely to be in icing state. Therefore

it is particularly important to meet the balance performance design under different working conditions. According to the requirements of product technical parameters

the structure of 550 kV high-capacity ice melting disconnector is designed. On this basis

the balance performance of ice melting disconnector under different working conditions is designed and checked. The results show that the balance performance of the 550 kV high-capacity ice melting disconnector meets the operation requirements under normal operation and 20mm icing conditions

and the balance performance design method adopted is generally applicable.
