Abstract
- Resistive superconducting current limiter (RSFCL) is a focus in the development of current limit technology, especially in the field of ac transmission. It has a significant effect of limiting current. However, the traditional double-wound noninductive pancake coil has an inevitable drawback. Due to its special structure the flashover would occur easily during the fault in high-voltage environment. That would make the SFCL working in an uncontrolled state. So, novel coil structures or connection modes are demanded to meet the protection of voltage source converter-based high voltage direct current. In this paper, the magnetic distribution of different flux coupling connection modes of the coils is analyzed through the simulations based on continuous pancake coil. A flux coupling type SFCL with pancake coils is designed and fabricated. The limitation process of the SFCL coils is analyzed through simulations and experiments in millisecond level. The parallel current sharing characteristics of the coils are researched through experiments in different impulse current. Meanwhile, a continuous pancake coil is made to study the series voltage sharing features of the coil. The result of this paper has certain guiding significance in the design of dc RSFCL.
