摘 要

随着国内经济的快速发展，人们渐渐走出了原来所固定的生存环境，越来越多的选择出去走走，世界那么大，想出去看看的想法在人们心中愈演愈烈。所以演变到出行方面高铁火车等的发展迅速，现在国内铁路正注重提速，加载等方面。各种提速道岔的信号装置广泛应用于全国范围内。

S700K型转辙机是由于提速需要从德国西门子公司引进设备，技术并经有我国的大力加工开发。在国内主干线上应用颇为广泛。该型号相对于其他的ZDJ系列的转辙机拥有更加的结构稳定先进，工艺精良等特点，而且大范围的解决了相关的信号维修人员对于的电机断线，接点有些时候接触不良，变化不定的故障电流，挤切销被折断移位和接触器不时的跳起等等的一系列惯性故障， 并可尽最大的可能做到“少维护，无维修”，正是国人最喜欢的状态。

ABSTRACT

With the rapid development of the domestic economy, the living environment of people came out of the originally fixed, more and more choose to go out for a walk, so much of the world, came up with idea to see growing in people's minds. So changes to the rapid development of high-speed trains, railway is now focused on speed, load, and so on. The signal devices are widely used in all kinds of speed-increasing turnouts nationwide.

S700K type switch machine is due to speed from Germany Siemens company has introduced equipment, technology and China's strong processing development. Is widely used in the domestic trunk lines. The model relative Yu other of ZDJ series of turned point machine has more of structure stable advanced, process sophisticated, features, and big range of solution has related of signal maintenance personnel for of motor break, contact some when contact bad, changes indefinite of fault current, squeeze cut pin was broken shift and contact device from time to time of jumped up and so on of series inertia fault, and can do maximum of may do "less maintenance, no maintenance", is people most like of State.

Key words: turnout for increasing speed ；signal device； S700K point ；machine failure

1.S700K的产品介绍和现状

1.1 产品介绍

S700K转辙机的产品起源于德文“Simens-700-kugelgewinde”,含义“西门子-具有6860N（700kgf）保持力-带有滚珠丝杠”的转辙机装置。

S700K转辙机是因为提速需求经从德国西门子公司引进先进的设备和技术，然后通过自身的吸收研发后，马上投入生产并且在我国全路主干线上推广且运用的转辙机，经过多年的不断实践证明，该型号的电动转辙机结构先进且工艺精良，不但帮助解决了长期以来困扰维修工作的电机断线，接点常接触不良，变化的故障电流，挤切销折断与移位接触器不时跳起等的一系列惯性故障，且做到“少维护，无维修”。
