摘　　要：城市道路照明负荷是单相负荷,将原三相变压器供电改由单相变压器供电,组成V/V0-V/V单相变压器-高压钠灯节电照明系统,降低了低压配网损耗,工程造价相对减少,提高了供电可靠性,同时可以达到下半夜路灯自动降压节电的节电效果。Urban road lighting load is single-phase load. The original power supply by three-phase transformers were replaced by single-phase transformers, composing of V/V0-V/V single-phase transformer that formed energy-saving lighting systems with high voltage sodium lamp. The system reduced the low-voltage distribution network loss and engineering costs, at the same time improved reliability, and achieved power-saving effect by the automatic voltage decrease in the latter night.
