Abstract

The invention provides a method and system for arranging a line for a preliminary qualification test of a submarine cable system, and the method comprises the steps: arranging a place, and setting a seawater environment simulation pool, a tunnel, a snake-shaped laying region, an underground threading cable trench, a directly buried cable trench, and an arc-shaped bent cable trench; laying a submarine cable at the arranged place, and dividing the laid line into various laid segments according to the difference of operation environments and laying states; installing submarine cable accessories;and completing the burying and seawater simulation environment arrangement according to the laying requirements. The method and system can achieve the arrangement of the submarine cable line on the land, increase the seawater environment simulation segment, enable the arrange of the line for the preliminary qualification test of the submarine cable system to completely represent the conditions ofthe laying design in the submarine cable standard, can guarantee that the long-term performances of the submarine cable system are checked truly, effectively, scientifically and objectively through the preliminary qualification test.

Description

technical field [0001] The present invention relates to the field of pre-qualification testing of submarine cable systems, and more particularly, to a method and system for arranging lines of submarine cable systems for pre-qualification testing. Background technique [0002] At present, relevant standards for submarine cables include "GB / T 32346.1-2015 Rated Voltage 220kV XLPE Insulated Large Length AC Submarine Cables and Accessories Part 1 Test Methods and Requirements" and "CIGRE TB 490:2012 Recommendations for Testing of Long AC Submarine Cables" with Extruded Insulation for System Voltage above 30(36)to 500(550)kV". Among them, in the overview of the pre-qualification test of the submarine cable system, it is written that the pre-qualification test is carried out on the electrical test of the finished cable sample with a length of about 100 meters, including at least one of each accessory. The minimum clear length of cables between accessories shall be 10 meters. How...
