直流电缆试验终端装置
摘要：
本发明涉及一种直流电缆试验终端装置，包括绝缘套筒、设于绝缘套筒两端的密封装置和均压罩、固定于绝缘套筒内的至少一个均压环、填充于绝缘套筒内的绝缘介质，直流电缆轴向贯穿绝缘套筒，均压环套设于直流电缆上、并与直流电缆之间存在间隙。安装时，将直流试验电缆穿进直流电缆试验终端内，并通过在绝缘套筒的两端安装密封装置进行密封，安装方便，能够重复利用；均压环套设于直流电缆上，改善直流电缆外屏蔽处的电场分布，使测试更稳定，试验效果好；均压环与直流电缆之间存在间隙，适用于不同横截面大小的直流电缆，且通过选择填充不同的绝缘介质或调控填充绝缘介质的介电性能以适应不同电压等级的直流电缆，使适用性更强。
摘要（英）：

The invention relates to a direct-current cable test terminal device which comprises an insulating sleeve, sealing devices and voltage sharing covers arranged on two ends of the insulating sleeve, at least one voltage sharing ring arranged in the insulating sleeve, an insulating medium filled in the insulating sleeve. A direct-current cable axially penetrates through the insulating sleeve. The voltage sharing ring sleeve the direct-current cable, and an interval exists between the voltage sharing ring and the direct-current cable. In the installation process, the direct-current text cable is penetrated into the direct-current cable test terminal, and the sealing devices are installed on two ends of the insulating sleeve for sealing, the installation is convenient, and reuse is available. The voltage sharing ring sleeve the direct-current cable, the electric field distribution at a shielding part outside the direct-current cable is improved, the testing is more stable, and the testing effect is good; in addition, the interval exists between the voltage sharing ring and the direct-current cable, the voltage sharing ring is suitable for the direct-current cable with different cross sections, and different insulating media can be selected for filling or the dielectric performance of the filled insulating medium is regulated to be adapted to the direct-current cables of different voltage levels, and the applicability is higher.
