Terminal for partial discharge tests on crosslinked polyethylene power cable of 10 kV or lower

2014 
The invention relates to a terminal for partial discharge tests on a crosslinked polyethylene power cable of 10 kV or lower. The terminal comprises a stress ring, a voltage-sharing sleeve and a high-voltage connecting voltage-sharing ring. Screws for fixing the stress ring to a cable shielding layer are arranged on the stress ring. The joint of the cable shielding layer and an insulator is sleeved with the lower end of the stress ring. An insulating cable core is sleeved with the voltage-sharing sleeve. A semiconductor connector of the voltage-sharing sleeve is connected with the lower end of the stress ring. Two to four umbrella skirts are arranged on the voltage-sharing sleeve. The upper end of the high-voltage connecting voltage-sharing ring is connected with a cable core conductor of the insulating cable core. Screws for fixing the high-voltage connecting voltage-sharing ring to the cable conductor are arranged on the high-voltage connecting voltage-sharing ring. The lower end of the high-voltage connecting voltage-sharing ring is provided with a high-voltage connector connected with a high-voltage cable. Due to the terminal, the test terminal can be conveniently and rapidly installed, material consumption is low, and the terminal can be repeatedly used. The peeling and cutting length of the ends of the crosslinked polyethylene power cable is decreased, time for peeling and cutting the cable and installing the terminal is effectively shortened, the test efficiency is improved, damage caused by a freon terminal to the environment is avoided, and test stability is improved compared with an oil terminal.
