针对到发线出岔电路在使用中,在外电网瞬间停电来电情况下会造成室内组合架零层的KZ或KF电源5A主、副保险烧坏的原因,提出了改进到发线出岔电路的方案,通过改进方案的实施,有效地解决了到发线出岔电路在外电网瞬间停电来电情况下会造成室内组合架零层的KZ、KF5A主、副保险烧的问题,确保了行车安全。
In the course of using the outgoing wire breakout circuit to the outgoing wire, under the condition of an instantaneous power failure of the external power grid, the cause of the burnout of the primary and secondary KA of the KZ or KF power supply in the zero layer of the indoor combined frame is caused, and the improvement to the outgoing wire breakout circuit of the outgoing wire Program, through the improvement of the implementation of the program, to effectively solve the hairline circuit breakout in the case of an external power grid instantaneous power outage will result in zero indoor KZ, KF5A floor combination of primary and secondary insurance burned to ensure traffic safety.
