1100kV气体绝缘金属封闭开关设备（gas—insulated metal-enclosed switchgear，GIS）是特高压电网中最重要的控制和保护设备，对确保特高压电网的安全稳定运行和可靠供电起着重要作用。特高压交流试验示范工程用1100kV／50kAGIS设备已不能达到开断系统短路电流63kA的要求，为满足未来特高压电网建设需求必须研制出1100kV／63kAGIS设备。分析并研究了国内外已有的特高压输电技术，从电网需求、仿真分析、结构设计、型式试验等多方面，系统论述了1100kV／63kAGIS设备的研制全过程。从理论上计算并分析了GIS核心部件断路器，详细阐述了四断口和两断口断路器设计结构，并进行了仿真模拟验证。经过方案比选提出了1100kv／63kA断路器型式试验解决方案。最终，四断口和两断口设计的断路器均依照国家标准完成了型式试验。结果表明，1100kV／63kAGIS设备的研制是完全町以实现的。

The gas-insulated metal-enclosed switchgear （GIS） is the most important control and protection equipment in 1 100 kV power grid and it plays important role of ensuring secure and stable operation and reliable power supply of UHVAC power grid. In view of the fact that GIS with breaking capability of 50 kA for 1 100 kV pilot power transmission project cannot meet the requirement of switching-off the short-circuit current of 63 kA, to meet the requirement of constructing UHV power grids in future, it is necessary to develop the GIS with breaking capability of 63 kA. On the basis of researching and analyzing existing UHV power transmission technologies home and abroad, the overall process of developing 1 100 kV GIS with breaking capability of 63 kA is systemically expounded in aspects of power grid demand, simulation analysis, structural design and type test. The core components of the 1 100 kV GIS with breaking capability of 63 kA are calulated and analyzed theoretically, and the structures of circuit breakers with two-contact and four-contact respectively are designed and simulative verifications of them are performed. After scheme comparison, a scheme to meet the requirement of type test for 1 100 kV GIS with breaking capability of 63 kA is proposed. Finally, according to national standard the type test of circuit breaker with four-contact and that with two-contact are completed. Type test results show that the development and manufacturing of GIS with breaking capability of 63 kA for 1 100 kV power grid can be utterly implemented.
