±800 kV 云广特高压直流工程具有大地回线运行方式和金属回线运行方式两种正常运行方式。金属回线断路器(metallic return transfer breaker，MRTB)的稳定运行决定以上两种运行方式能否转换成功，直接影响直流输电工程的安全稳定运行。以±800 kV云广特高压直流工程实际运行过程中发生的MRTB跳跃现象为切入点，深入分析该断路器发生跳跃现象的主要原因，并有针对性地提出了解决跳跃现象的方案。所提方案已通过试验室和工程现场试验验证，均得到良好的效果，并且对以后多回直流建设具有推广应用参考和工程经验借鉴的价值。

Yun-Guang ± 800 kV UHVDC project has two ways to run in a normal operation mode, including ground return operation mode and metallic return operation mode. Metallic return transfer breaker’s (MRTB) steady operation determines whether the two ways can have a successful conversion, which directly affect the safe and steady operation of the DC transmission project. The phenomenon of“MRTB jump”happened in the Yun-Guang ± 800 kV UHVDC project which in actual operation is taken as the main point, in-depth analysis of the main reason for the phenomenon of MRTB jump is made, and the program to solve the problem is pertinently proposed. The program has been verified by the test in laboratory and at the project site, and the solution has reference value for promotion and application and could be the example of engineering for the future construction of multi-circuit HVDC.
