大编组站、旅客站和其他用地长度受限制的咽喉区大多采用交分道岔,但交分道岔也是故障多发处所。在其故障发生的概率中,交分道岔旷量引起的表示杆卡口失去表示的故障占了很大的比重。天津电务段研制的交分道岔旷量消除装置,在对原道岔连接销功能分解的基础上,增加了“消除旷量”的“潜在”功能。阐述了消除道岔旷量的3种方案及其利弊分析,详细介绍了道岔旷量消除装置的原理、构成和功能。
Large marshalling stations, passenger stations and other restricted length of the throat area are mostly used to turn point turnout, but turnout turnout is also a fault multiple premises. In its probability of failure, turn off the turnout caused by the bar that the failure of the said mount accounted for a large proportion. On the basis of decomposing the functions of the connecting pins of the original turnout, the device for eliminating the turnout eliminated by the Tianjin Electricity Affairs Section has added the function of “potential” of “eliminating”. The three kinds of schemes to eliminate turnouts and their advantages and disadvantages are expounded. The principle, constitution and function of the turnouts elimination device are introduced in detail.
