| 摘 要： | 如何提高绝缘设备的抗污秽能力是我国1 000kV特高压变电站的工程设计中需要解决的重要问题之一。对变电站发生污闪事故的主要影响因素进行分析,结合1 000kV皖南特高压变电站工程的实际特点,从工程设计的角度研究了特高压变电站工程的防污秽措施,推荐在该工程中采用防污双伞型瓷绝缘子;采用GIS设备,降低变电设备的绝缘子数量,提高特高压变电站耐污闪能力。

| Abstract: | Improving insulation equipment contamination prevention capability is one of the major problems facing the nation's 1 000 kV UHV substation design.Major factors affecting substation flashover due to contamination are analyzed.Combining features of 1 000 kV Wannan Substation project,UHV substation contamination prevention measures are studied from engineering design point of view.It is recommended that double-umbrella shaped porcelain insulators should be used.Using GIS devices can reduce the number of insulators and improve anti-flashover capability of UHV substations. |
