Abstract

In Recent years, with the rapid development of urban rail transit at plateau and transformation and booming of the electrotechnical industry in China, it has put higher requirements for large-capacity DC air circuit breaker (LC-DCCB) which plays a significant role in protection. But when the short-circuit current is interrupted in LC-DCCB at plateau, the probability of interrupting failure increase, which is harmful to the urban rail transit sustain its stability and reliability. So how to extinguish the arc in which generated between the contacts when the contacts opening in LC-DCCB at plateau quickly and reliably remains a critical issue to be resolved. This paper established a transient magnetohydrodynamics (MHD) arc model of LC-DCCB at plateau considering the turbulence effect, the dynamic characteristics and the key behavior of the arc during short-circuit current interrupted at different altitudes were studied, and the primary courses of difficulty of arc interruption in LC-DCCB at plateau were concluded. An improved model with interleaved U-shaped splitter plates was proposed combined with theoretical analysis which can improve the interruption performance of LC-DCCB at plateau. This study can provide a theoretical basis for design and improvement of LC-DCCB at plateau.
Through simulation results we can see that different altitudes can cause different environmental parameters and physical properties of air, which effects the arc behavior in LC-DCCB significantly. At 0 km altitude, the arc can extinguish successfully. At 2 km and 3 km altitudes, although the arc extinguish successfully, nevertheless, the arc will re-strike after a few milliseconds. At 4 km and 5 km altitudes, the arc can not extinguish. The physical parameters of air change with the altitude rases, which lead the arc enters the splitter plates in advance. One can found that the arc root viscous and trailing phenomena in LC-DCCB will appear during the full-dynamic arc simulation. When the arc root moves at the horizontal arc runner to a certain point, the movement speed of the arc root will decrease, and then the arc root will stop its moving or even move in reverse direction, while the high temperature gas adjacent to the arc root will cause the electric field distortion at the entrance of the arc chamber. The characteristics of arc root movement are different with altitude raise. Meanwhile, under the joint action of electromagnetic and airflow field, the reverse phenomenon of arc roots on both sides of the center line in the arc chamber will appear, the arc presents multi-peak shape. The reverse phenomenon of the arc between the splitter plates varies with the altitude, which is a key factor leading to the post-arc re-strike. An improved structure with interleaved U-shaped splitter plates in the arc chamber can restrain the arc reverse movement between splitter plates effectively.
Through simulation and analysis in this paper come to the following conclusions: (1) Arc re-strike will occur during LC-DCCB interrupts short-circuit current at plateau, which will lead to the difficulty of interruption; (2) The arc root viscous and trailing phenomena will intensify with the altitude raise; (3) The arc reverse movement in LC-DCCB is a key factor for post-arc re-strike; (4) The interleaved U-shaped splitter plates can restrain the arc reverse movement between splitter plates effectively, which improve the arc extinguishing performance at plateau of LC-DCCB to some extent.

Key words： High altitude large-capacity DC air circuit breaker (LC-DCCB) arc root trailing arc reverse movement post-arc re-strike
