KPD系列电动平车优点是由于不用电缆，不仅安全，而且不怕烫、不怕砸、不妨碍交叉运输。KPD系列低压轨道供电平车是通过地面控制降压系统，把380V电源电压降至36V的安全电压，馈电给导电轨（导电轨兼做平车的走行轨道）及中间滑触线。。。。。。。。。但不适于喷漆或喷丸房等特殊环境。
As a cable-free vehicle, the KPD-series carriage has high security and flexibility. For the KPD-series low-voltage rail-way power-supply carriage, the ground step-down transformer of the carriage can step down the voltage from 380v to 36v, and then links it to the conducting railways. The sliding blocks then lead the electricity to the step-up transformer equipped on the electric flat carriage. After that, the step-up transformer raise the voltage up to 380v and then the electric flat vehicles start operating. Since the railway plays a very important role in operating the KPD-series vehicles, the installation requirement of this kind of railway is relatively high compared to that of other kinds of flat carriage. Insulation treatment and compensate copper bars are needed for the railways. Additional step-down transformers are preferred. As a result, the cost of this kind of railways is higher than other types. But as a whole, the KPD-series vehicles are cost-effective and very popular in the market. |
