京包线古店站信号设备大修时 ,电源屏采用特锐公司生产的ＰＮＸ1 2 0Ａ型智能电源系统。在设备调试过程中发现 ,2 5Ｈｚ电源模块输出的轨道 3(ＸＸＧＪＺ、Ｆ)在接入负载后上电时 ,2 5Ｈｚ电源自动保护 ,没有输出 ,而甩开负载供电时输出正常。1.原因分析。古店站为非电化区段 ,
When Beijing Guobao line Gudian station signal equipment overhaul, the power supply screen uses Teuui PNX120A smart power system. During the commissioning of the equipment, it is found that when the rail 3 (XXGJZ, F) output by the 25Hz power supply module is powered on after being connected to the load, the 25Hz power supply is automatically protected and has no output, and the output is normal when the load power is thrown away. 1. Analysis of the reasons. Gudian station for the non-electrochemical section,
