铁道电气化 meaning in Chinese
railroad electrification
railway electrification
Examples
- On the railway of electrization , power supply mode is requested to be the single - phase alternating current
在铁道电气化牵引区段，牵引供电网采用单相工频交流电供电方式。 - However , due to the special railway communication structure , it has n ' t yet been used massively in railway remote control at home and abroad
由于铁道电气化的独特性，国内外迄今还没有成熟的gprs无线移动通信系统在远动中的应用实例。 - As a high - tech company dedicated to the design and manufacturing of power automation devices and systems , sunrise - power can provide integrated technical solutions for various utilities
电力系统自动化继电保护通信工程计算机自动控制电子技术及其控制铁道电气化电机电器高压电器人力资源管理市场营销策划等专业。 - Traction transformers are important devices in electric railways system , and secure operation has significant influence on the stability of electric railways system
<中文摘要> =牵引变压器是铁道电气化系统中重要的电气设备，在电气化铁道系统中占有极其重要的地位，它的安全运行与否，直接关系到铁道电气化系统能否连续稳定的工作。 - At present , differential protection is often used as the main protection for traction transformers . however , the existing of certain factors , such as magnetizing inrush , over - excitation , ct saturation and mismatching of ct ratio , will result in that it is hard to distinguish state current and fault current , and differential protection misoperation or maloperation , then secure operation of electric railways system will be threatened
目前，牵引变压器通常采用差动保护作为主保护，但是在某些因数的影响下差动保护并不能准确的区分牵引变压器内部故障或非内部故障，如故障电流与变压器处于励磁涌流、过励磁， ct饱和及ct变比不匹配等情况下的状态电流就很难准确的区分，可能造成保护误动或拒动，从而危及整个铁道电气化系统的安全运行。
