描述

AB 150-B97NBDB
在防雷装置的设置上人们往往比较注意外部防雷装置和内部的电涌保护,容易忽视等电位连接在雷电防护的重要作用。有时还特意设置单独的接地装置,单独的引下线,还错误的提出“共网不共线,分类接地网,不串不共用,一点接地法”的口号,一方面给设计施工增加了难度和增大了开支,另一方面违背了等电位的基本原理,会给被保护设备以及人身安全造成潜在的威胁。
    1、基本概念
    防雷等电位连接——是将分开的导电装置各部分用等电位连接导体或电涌保护器(SPD)做等电位连接。它包括在内部防雷装置中,其目的是减小建筑物金属构件与设备之间或设备与设备之间由雷电流产生的电位差。防雷等电位连接区别于电气安全的等电位连接,最主要是将不能直接连接的带电体通过电涌保护器做等电位连接。
    等电位连接网络——是对一个系统的外露各导电部分做等电位连接的各导体所组成的网络。
    共用接地系统——是一建筑物接至接地装置的所有互相连接的金属装置(包括外部防雷装置),并且是一个低电感的网形接地系统。
    接地基准点——是一系统的等电位连接网络与共用接地系统之间唯一的一点连接点。
    信息系统的等电位连接:
    各种形式的电子系统的应用在不断增加,这些系统包括计算机、通信设备、控制系统等,在国际电工委员会的标准中将它们统称为信息系统。对信息系统的外露导电部分应建立等电位连接网络,原则上一个等电位连接网络不需要连到大地,但通常所考虑的所有等电位连接网络都会有通大地的连接。

主营:本特利,英维思,伍德沃德,福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐,ACSO,力士乐等各大品牌的DCS系统配件,机器人系统配件,大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
