摘要

由于技术水平和实验条件的限制，激光PWP法还没有得到全尺寸高压直流电缆中的空间电荷分布。本文设计了一套空间电荷测试系统，用于全尺寸长电缆的空间电荷测量。为了验证该系统的能力，在+50kV至+200kV电压范围内，测量了绝缘厚度为15mm的全尺寸10m长电缆的空间电荷分布。然后进行空间电荷注入实验，保持外加电压+200kV，持续48小时，获得空间电荷注入数据。

Space Charge Measurement System Based on Laser PWP Method for the Full-size Long HVDC Cable

Because of the limitation of technical level and experimental conditions, the space charge distributions in the full-size HVDC cables has never been obtained by the laser PWP method. In this paper, a space charge test system was designed for the space charge measurement of the full-size long cable. To verify the capabilities of the system, space charge distributions in full-size 10m long cable with 15mm thick insulation were measured, while the voltage range was setting from +50kV to +200kV. Then the space charge injection experiment is carried out, and the applied voltage is maintained +200kV, which lasted for 48 hours and the space charge injection data are obtained.
