摘要：现代社会，人们出行节奏快，交通设备则现的特别重要，而其中作为出远门的交通铁路交通则更为重要。 

铁路交通是世界上最重要的交通之一，而其在我国更是覆盖广泛，铁路交通作为四大交通之一，其四通八达的贯穿了我国整个地域，加强了各个省份的联系，铁路交通作为交通运输之一，它比公路交通更加快速，更加节省时间，比其飞机，它更加安全，更加方便，而比起海上交通，它跨度更加广泛，运输范围更大，是人们出行较方便的一种工具。79763

在铁路交通中，其最重要的则是列车与轨道部分，这俩部分的完善才能使铁路正常运行，而轨道的排列通畅则是铁路覆盖范围广，四通八达的重要基础之一，其中转辙装置则是轨道设备里最重要的一环，转辙装置的成功应用是铁路交通中其巨大变革之一，他的出现成功解决了铁轨占地面积广的问题，实现了铁路从一条轨道到另一条轨道的跨轨运行，成功的将不同铁轨连接起来，使铁路真正的成为重要的交通之一。

在转辙装置中，转辙机是转辙装置的核心与主体，是铁路室外的三大设备之一，转辙装置的主要作用是实现道岔的锁闭与转换，其除了需要转辙机这个主要部件外，还得包括各类杆件，锁闭装置与各种安装部件等。而且转辙机也包含于信号设备中，信号设备在铁路中是作为一种可以提高运输效率，可以集中指挥的基础设施。在列车行驶过程中转辙机可以对轨道进行改变，可以实现道岔的转换。可以保证列车能安全地实现道岔转换，使其可靠的运行。

本文就主要对道岔转辙机进行一系列介绍，其详细介绍ZD6系列电动转辙机，本文的主要内容是在阐述ZD6电动转辙机的同时，设计一种良好的实验台，可以实现对转辙机的操作与运行，其重点是对ZD6道岔电路原理图的设计与描述，其中对各类继电器的运用和转辙机的节点变化的描写是电路的重点与难点。

Abstract：Modern society, people travel fast, traffic equipment is now particularly important, and as a long distance traffic, rail traffic is more important。

Railway transportation is one of the most important traffic in the world, and in China is more extensive coverage, as one of the four major railway traffic, the extensive throughout our entire region, strengthen the various provinces, as one of the railway transportation, road traffic than it more quickly, more save time, than the plane, it is safer, more convenient, and compared with the maritime traffic, which span more widely, transportation more convenient, is a tool for people to travel。

In railway transportation, which is the most important part of the train and rail, the two parts of the improve in order to make the normal operation of the railway track, and the arrangement is unobstructed railway coverage, one of the important basis of connected, wherein the switch device is one of the most important equipment in the orbital ring, the successful application of switch device is one of the railway traffic in the great revolution, he has successfully solved the problem of rail wide area, realizes the railway from one track to cross track running another track, success will connect different tracks, the railway has become one of the important real traffic。

In the switch device, switch machine is the core and main switch device, is one of the three major outdoor equipment of railway, the main function is to realize locking switch device and conversion switch, which in addition to the main switch machine parts, also including various types of rod locking device and various installation and switch components。 The machine is an important part of the signal equipment, and the railway signal equipment is centralized command, and an important infrastructure to improve the transportation efficiency。 While the switch machine in which the role is to change the track during the train running, an important element in realizing the switch conversion and railway station centralized control is in the arrival of the train。 When Punctual and reliable switching of switches is the safe operation of trains
