Abstract

A rail car for superconducting A direct current limiter disclosed in the invention comprises a car body, and an inner side supporting frame and an outer side supporting frame are arranged at the two ends of the surface of the car body; wheels are arranged at the bottom of the car body; the outer side supporting frame is fixedly connected with the car body through a bolt a; the invention further discloses a method for disassembling and assembling a superconducting direct current limiter by using the rail car. According to the rail car, the inner side supporting frame and the outer side supporting frame are used for supporting the inner side flange and the outer side flange correspondingly in the disassembling and assembling processes, integrated installation of the low-temperature dewar ofthe large superconducting direct-current current limiter is conveniently achieved, and meanwhile maintenance and replacement of internal components of the superconducting direct-current current limiter in the later period are facilitated; the technical problems of difficult disassembly, difficult hoisting, inconvenient maintenance and the like in the system integration assembly and maintenance test process of the large-scale superconducting direct current limiter are solved, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of superconducting DC current limiter installation and maintenance equipment, and specifically relates to a rail car for a superconducting DC current limiter. The invention also relates to a method for disassembling a superconducting DC current limiter by using a rail car. The invention also relates to The invention relates to a method for assembling a superconducting DC current limiter by using a rail car. Background technique [0002] Flexible DC transmission technology is an important means for large-scale access and large-scale interconnection of renewable energy in the future. However, the large-scale flexible HVDC transmission projects that have been put into operation do not have the ability to clear line faults. Therefore, quickly removing and isolating DC faults is an important development direction for the safety assurance of large-scale flexible HVDC transmission projects. [0003] The supercondu...
