摘要:
目前,应用于国家电网特高压交流示范工程1 100 kV GIS 设备有两种不同的技术方案:一种GIS 设 备是带合闸电阻的双断口断路器,隔离开关带电阻;另一种GIS 设备则是带合闸电阻的四断口断路器,隔离 开关不带电阻。笔者主要从气室压力、绝缘尺寸、灭弧单元的选择、断路器带合闸电阻的定尺、隔离开关的设 计等方面介绍了两种不同技术方案, 同时介绍了两种技术方案在特高压GIS 和HGIS 变电站的布置上的不 同之处。结果表明,两种技术方案都有各自的特点,都可以满足特高压变电站在技术参数和布置结构等方面 的要求。
Abstract:
There exist two technical solutions for a 1 100 kV GIS in the State Grid of China Ultra High Voltage AC Pilot Project. One adopting a double-break circuit breaker with a closing resistor, whose disconnector has a resistor; the other adopting four-break circuit breaker with closing resistor, whose disconnector has no resistor. This paper introduces the two technical solutions from such aspects as gas pressure, dielectric dimension, choice of interrupting units, specification of a circuit breaker with a closing resistor, and design of disconnectors. Moreover, it illustrates the difference between the two solutions in layouts for UHV GIS and HGIS substations. Conclusions are drawn that both solutions have self characteristics and can meet the requirements of UHV substation for technical parameters and layout.
