| 摘要: |
| 为提高磁浮列车悬浮传感器的可靠性，分析在雷击、电源干扰等工况条件下的浪涌产生机理，确定浪涌冲击试验的内容，从通流量的角度说明已有防浪涌电路设计的可行性,并指出其在高温环境下在可靠性方面存在的不足。分别从降压和分流的角度进行分析，通过在原有电路中并接大容量电容的方式降低浪涌对敏感器件的冲击，从而提高传感器电源的抗浪涌冲击能力。 |

| Abstract: |
| In order to improve the reliability of the levitation sensor in maglev train, the mechanism of the surge under the circumstances of thunder strike and power supply interference were analyzed, and the details of the surge experiment were confirmed. In view of current flow capacity, feasibility of the existing circuit design to suppress surge was explained, and the insufficiency of the reliability at high temperature was pointed out. From the analysis in the aspects of voltage reducing and current shunting, the impact of the surge to the sensitive components is reduced by a large-capacity capacitance shunted in front of the original circuit, and the capability of the sensor power to suppress surge is promoted. |
