| 摘要: |
| 雷达站多位于高雷暴环境之中，其电源系统容易遭受雷击。针对雷达站电源系统的防雷问题，采用三级电涌保护器防护加隔离变压器的综合防护系统进行防护。首先利用三级电涌保护器防护快速降低雷电流的幅值，其次利用隔离变压器完全隔离电磁脉冲能量，彻底消除雷电流残压，从而达到保护效果。通过建模仿真和实际测试可以发现，该综合防雷系统对于雷电流的冲击具有较好的防护能力，能够保证雷达站电源系统在雷电环境下正常供电，确保了雷达装备和操作人员的人身安全。 |

| Abstract: |
| Most radar stations are located in high-thunderstorm environment, and their power system is vulnerable to lightning strikes. Aimed at the problem of lightning protection in power system of radar station, the integrated protection of three-level surge protector and isolation transformer is adopted. Firstly, three-level Surge Protection Device (SPD) is used to reduce the amplitude of lightning current rapidly, then the isolation transformer is used to completely isolate the electromagnetic pulse energy and eliminate the residual voltage of lightning current, so as to achieve the protective effect. Through modeling, simulation and actual test, it can be found that the integrated lightning protection system has good protective effect on the impact of lightning current, can guarantee the normal power supply of the power system of radar station under the lightning environment, and can ensure the safety of radar equipment and operators. This work is supported by Army Scientific Research Project (No. ZBBG415238GT). |
