关于区间继电式逻辑检查停电监督方案探讨
|
摘要
区间继电式逻辑检查电路已在国内普速铁路广泛应用,其有效解决区间因轮轨间接触电阻不满足轨道电路分路要求而造成的区间列车失去分路问题,提高自动闭塞区段运输的安全性,但当发生瞬间停电或计划停电时,恢复供电后可能导致逻辑检查电路错误解除防护。针对上述问题在基本保持原电路的前提下,增加停电后再恢复供电时,逻辑检查电路保持安全防护状态的功能,进一步提高自动闭塞区段特殊情况下的安全保障能力。
Relay type track vacancy logical detection has been widely used in domestic convenient railway, which effectively solves the problem of train shunting lost in section caused by the contact resistance between wheel and rail does not meet the requirements of track circuit shunting, and improves the safety of automatic block section transportation. However, when instantaneous power failure or planned power off occurs, the protection status of sequence-logic-check circuit will be released by mistake after the restoration of power supply. Aiming at the above problems, on the premise of basically keeping the original circuit, the function of maintaining the safety protection state of the sequence-logic-check circuit is added when the power supply is restored after the power failure, so as to further improve the safety guarantee capability of the automatic block section under special circumstances.
