“…Based on a 400 V/25 A bridge type SFCL developed in 2002, the Institute of Electrical Engineering (IEE) of Chinese Academy of Sciences (CAS) successfully developed another 10.5 kV/1.5 kA bridge type SFCL, which can react within 2 ms when fault current occurs, and limit the fault current from 3500 A to 635 A, with the fault current limit rate of 82% [35]. In 2005, this bridge type SFCL was put into demonstration operation in Loudi substation, Hunan Province, running in the power grid for more than 11 000 h [45].…”

With the increase of electricity demand and the rapid development of renewable energy generation, it is becoming more and more important to ensure the safety and stability of power grid, where a superconducting fault current limiter (SFCL) could play an important role. In recent years, a lot of research work has been done in China on the application of high temperature superconducting (HTS) power technology, especially in the aspects of superconducting fault current limiting technology, superconducting fault current limiting-breaking technology, superconducting fault current limiting- magnetic energy storage technology, and superconducting fault current limiting transformer technology. A number of demonstration projects on SFCL were also conducted. In this paper, the research progress of HTS fault current limiters (both AC and DC) in China in recent years is introduced, including the completed projects and the on-going work. The possible application direction of SFCL in the future is proposed.

“…As shown in Figure 1, the control circuit of the indoor part is shown. When the turnout is rotated from the positioning to the reverse position, the first level control circuit is checked by the 3-4 coils of 1DQJ to see if the interlocking conditions are met [4] . The path of the 1DQJ excitation circuit during incoming circuit operation is KZ--CA61-63-SJ81-82-1DQJ3-4-2DQJ141-142-CAJ11-13-FCJ61-62-KF.…”

This article starts with the principle diagram of the road fork control circuit. By analyzing the working principle of the launching circuit and the working circuit, the common fault phenomenon of the control circuit is characterized by feature extraction. Finally, the common fault nodes of the ZD6 -type rut -type cross -channel control circuit with dual -machine traction are given. When faults occur, how to efficiently and quickly locate specific fault positions, which can effectively guide on -site electrical personnel to solve the emergencies.
