电车的节电除了依靠加强管理、提高驾驶操作技术外,最根本的办法就是电车电气控制系统的技术革新。目前,采用可控硅脉冲斩波调速装置与变阻调速装置相比节电可达20%左右。
In addition to strengthening the management of trains and improving their driving skills, the most fundamental solution is the technical innovation of the tram control system. At present, the use of SCR pulse chopper speed control device compared with variable resistance speed up to about 20%.
