交流接触器是一种应用非常广泛的电气元件，维修电工在工作中经常遇到。现本人就工作中遇到的几种典型案例，来和大家分享一下。这些案例大致分为以下几类：一：交流接触器的线圈电压等级问题二：动作频繁的交流接触器三：尺寸比较大的交流接触器四：工作环境中粉尘比较多的交流接触器下面来详细地一一介绍。交流接触器的线圈电压等级问题我们在工作中，比较常用的交流接触器线圈的电压等级有：AC36V、AC220V、AC380V。
The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture.
In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.

人机界面硬件构成人机界面产品由硬件和软件两部分组成，硬件部分包括处理器、显示单元、输入单元、通讯接口、数据存贮单元等，其中处理器的性能决定了hmi产品的性能高低，是HMI的核心单元。HMI软件一般分为两部分，即运行于HMI硬件中的系统软件和运行于PC机Windows操作系统下的画面组态软件(如BAMS软件)。使用者都必须先使用HMI的画面组态软件制作“工程文件”，再通过PC机和HMI产品的串行通讯口、USB接口、以太网接口，把编制好的“工程文件”下载到HMI的处理器中运行。
