摘要
我国电气化铁路牵引供电的基本要求是：200 km/h及以下采用户内空气绝缘开关设备（27.5 kV单相单极居多）,200～250 km/h采用户外敞开式开关设备（2×27.5 kV和55 kV单相双极居多）,250 km/h以上采用户内气体绝缘开关设备（2×27.5 kV单相双极居多）.伴随着高速铁路的快速发展,标准中规定使用的电气化铁道开关设备存在的问题也逐渐暴露出来.
The basic requirement of traction power supply for electrified railway of our country is： indoor air insulated switch equipment is used at 200 km/h and below （single-phase unipolar 27.5 kV mostly） ; outdoor open switch equipment is used at 200-250 km/h （single-phase bipolar 2 ×27.5 kV and 55 kV mostly）, indoor gas insulated switch equipment is used at more than 250 km/h （single-phase bipolar 2 × 27.5 kV mostly）. Along with the rapid development of high-speed railway, the problems of electrified railway switch equipment which the standard stipulates have gradually exposed.
