Cable line AC voltage withstand test method and system based on shunt reactor

Abstract

The invention discloses a cable line AC voltage withstand test method and system based on a shunt reactor. The method comprises the following steps that: a to-be-tested cable line is equipped with a shunt reactor, and the shunt reactor is used for compensating the ground capacitance current of the cable line; and in a cable line AC withstand voltage test adopting a series resonance mode, the shunt reactor replaces a test reactor to test the AC withstand voltage of the cable line. When the cable AC voltage withstand test is carried out, the shunt reactor of the cable line is adopted to replace a test reactor, and the problems that a large-tonnage test reactor is difficult to transport and hoist and the purchase cost of the test reactor is high are solved.

Description

Technical field[0001]The present invention belongs to the technical field of cable line withstand voltage test, and in particular, the present invention relates to a cable line AC withstand voltage test method and system for a parallel reactor.Background technique[0002]With the development of urban development, long-distance high voltage rating cables are expanding in the city. The weak link of the cable line is the terminal head and intermediate connector. Due to the poor design or production process, it is defective; where some defects can be detected in the construction process and acceptance test, but more is running Gradually develop, deteriorate. Therefore, when the cable is newly laid, the relationship level and joint process of the cable can be detected by the AC withstand voltage test method, and hidden dangers and defects can be found in advance to ensure the safe and reliable cable operation.[0003]In recent years, due to the large number of cable crossings, long distances...
