    摘 要:為解決戶內電纜終端因引線通道安全距離不足造成的無法開展耐壓試驗的問題,設計了一種應用于室內有窗變電站中戶內電纜終端開展高壓電纜交流耐壓試驗的引線架設裝置。該裝置采用基于絕緣隔離管的設計方案,從線芯導體、絕緣材料、絕緣表面結構及可調支架四部分進行了模塊設計,經在多條110 kV電纜線路交流耐壓試驗中現場應用,解決了戶內電纜終端耐壓試驗引線通道緊張,無法實現被試終端與試驗設備安全相連的問題。

    Abstract: In order to solve the problem unable to carry out secure connection tests caused by indoor cable terminal test lead channel tension, this paper design a set of high voltage cable test wire erection device used for inside cable terminal of indoor transformer substation with windows to carry out high voltage cable alternating current (AC) voltage withstand test. This device adopted the design scheme based on insulated isolation tubal. The module was designed in four parts including cable core conductor, insulating material, insulating surface structure and adjustable support. After the application of field verification of AC voltage withstand tests in multi-110 kV cable circuits, there is no tension for the indoor cable on the terminal voltage test of substation leads channel. The tested terminal realizes the safety connection with the testing equipment.
    Key words: high voltage cable; indoor transformer substation; inside cable terminal; alternating current voltage withstand test; lead wire erecting device
