摘要
为提高整个网侧高压电气系统的可靠性和冗余度,研究设计具有双真空断路器的动车组网侧柜。以某动力集中型电动车组动力车网侧柜设计为例,从网侧高压设备电气原理、设备布置、绝缘性能、柜体结构、安全等方面,分析具体设计方案。该方案提高了动车组真空断路器冗余性、使网侧电路更安全、可靠。
In order to improve the reliability and redundancy of the whole line side cubicle system,the line side cu⁃bicle of EMU with double vacuum circuit breaker is studied and designed.Taking the design of a power-centralized EMU as an example,the design scheme of line side cubicle is analyzed and introduced from the aspects of electrical principle,equipment layout,insulation performance,cubicle structure and safety of high-voltage equipment.The scheme improves the redundancy of the vacuum circuit breaker of the EMU and makes the line side cubicle safer and more reliable.
