摘要

交联聚乙烯由于其电气性能、结构轻便等优势被广泛应用于高压交直流电缆绝缘领域，但是近年来因电缆故障导致的停电事件呈现出逐年增多的趋势。文中针对某水电厂主变压器空载充电过程中存在的500 kV交联聚乙烯电缆外护套对夹件间隙放电的问题。首先，利用ATP-EMTP仿真软件建立了全厂一次设备电磁暂态仿真分析模型，对导致电缆铝护套放电现象的故障原因进行了分析；然后，对不同种类的故障治理措施进行比较；最后，提出了针对性解决方案。

Abstract

Due to the advantages of electrical performance and light structure

cross-linked polyethylene (XLPE) is widely applied in the insulation field of high-voltage AC/DC cable. However

in recent years

the number of power outages caused by cable faults has been increasing year by year. Aiming at the gap discharge problem of 500 kV XLPE cable sheath to clamp during the no-load energization of main transformer in a hydropower plant

firstly

ATP-EMTP software is used to establish the electromagnetic transient simulation analysis model of primary equipment in the whole plant. Then

the fault causes of discharge phenomenon of the cable aluminum sheath are analyzed

and the different kinds of fault treatment measures are compared. Finally

the corresponding solution is put forward.
