移频自动闭塞及机车信号是一种频率调制式自动闭塞制式,从1965年开始研制,目前已推广使用。移频自动闭塞制式能够满足多种牵引动力要求,对交流、直流电力牵引区段牵引电流所产生的谐波干扰和内燃机车的电磁干扰等,都具有较高的抗干扰性能。本文介绍了移频自动闭塞制式的主要特点和电路方框图,并着重地叙述了交流电力牵引区段牵引电流工频基波、谐波干扰分析和有关数据。同时,对移频自动闭塞频率参数的选择及其抗干扰性能做了一般论述。文中还对非电化区段工频50赫的迷流干扰及内燃机车的电磁干扰等提供了测试数据。

Abstract Besides the consideration of reliability and suitability in the selection of design scheme and operating mode of the protection, four prob- lems associated with the teliability and operating time are mainly ana- lysed. Measurements and methods for solving these problems are presented: (1) measurements for transmitting a block signal for a short time when a forward fault is detected; (2) method for solving the maloperation prob- lem of the COMMUNICATION INTERRUPT UNIT in the GROUND FAULT PROTECTION when a ground fault occurs in a ring network or a parallel- ed line system; (3) method for solving the brief maloperation problem of zero sequence directional relay after the clearing of a external fault; (4) method for deleting the additional time delay when the direction of fault power is changed. High speed operating is achieved without sacrifice of reliability. The overall operating time of the protection is less than 15 ms and in most cases it can operate within 10ms.
