SS 9-type trunk passenger electric locomotive, code-named SS9. To be mature Shaoshan series electric locomotive technology-based, using a number of international passenger locomotive advanced technology, is China's trunk railway traction power of the largest passenger train locomotives. Locomotive circuit uses three sections ranging from a half-controlled bridge rectifier circuit, three motors in parallel, non-level field weakening and increased feed resistance braking to realize the whole process of the variable speed locomotive. There 8668kVA locomotive built large capacity main transformer to achieve a six-axis electric locomotive transformer and the smoothing reactor and filter reactor integration. Locomotive with a power supply capability to train, supply voltage DC600V, capacity of 2 × 400kW. Locomotive used on the hollow shaft wheel drive six-link flexible bodies and the traction motor bearing type full suspension frame bogie axis, and lamination machine seat with the whole body 900kW pulse current traction motors; a second suspension system and infrastructure braking system structure design is reasonable, to meet the 170km / h using the requirements of good dynamic performance.
A locomotive of the aerodynamic shape optimization of design and lightweight design, with wall-type all-steel welded structure carrying the body and the lightweight components designed to meet the requirements of locomotive axle load 21 tons; locomotive cab applied ergonomic principles of design, structure, decorated with all-inclusive environment, elegant and easy to manipulate. Look for the micro-flow end of a thread-type arc shape. Locomotive characteristics of constant current quasi-constant speed control mode, can be a good start to play the greatest traction locomotives, locomotives equipped with air switch / slide protection system, the transfer axle load compensation control, wheel-rail lubrication system, automatic train safety monitoring device. LCU logic control unit and the use of microcomputer control system, so that locomotive control system has control, diagnosis, monitoring. Bogie wheel hollow shaft motor with full-suspension, reducing the unsprung weight. Through unilateral straight-tooth gear, the traction motor torque into a round, spread by the low level rod body, improve locomotive traction.May be pulling 18 passenger cars in the 16 ‰, 14 ‰, 12 ‰, 10 ‰ growing up on the ramp, respectively, in order to 84km / h, 92km / h, 96km / h, 105km / h speed of constant speed uphill, greatly improves The average operating speed. Locomotive power continued to 4800kW, a maximum speed of 170km / h, car length 22216mm, axis Co-Co, current system is a single-phase AC power frequency. In November 2002 to improve into SS9G, made by Zhuzhou Electric Locomotive Works.
