描述

BERNECKER 3IF260.60-1

 电力变压器作为电力系统中的核心设备,其稳定可靠运行对电力系统是至关重要的,但是任何设备都不能保证永远不出故障,变压器出故障也是在所难免的,但是我们可以通过分析变压器的运行状态参数,提前预测和避免变压器可能出现的故障,提早做打算,从而保证变压器的运行。因此电力系统的工作人员应该重视变压器的运行参数研究,加强对变压器运行状态的分析和故障诊断的研究,这样才能保证电力系统的长期高效稳定地运行。
变压器漏油。变压器漏油是一个对变压器安全运行造成巨大影响的事故,如果发生漏油,将直接导致变压器运行瘫痪,产生环境污染,给企业带来巨大的经济损失,影响国民经济生活。变压器漏油根据大量的经验总结,主要发生在两个位置,一个是油箱的焊接处,一个是油箱的防爆管。防爆管由于结构中存在一个玻璃膜,在变压器运行时产生震动,震动会将玻璃膜震破碎,如果不能及时发现,就会造成漏油的后果。因此后期可以通过加装调压阀来取消安装防爆管所带来的隐患。焊接处漏油往往是因为焊接质量不过关造成,因此一方面要加强焊接工艺,另一方面要加强巡检,及时发现及时处理。
变压器铁芯多处接地。根据国家标准规定,电力变压器的铁芯位置,只允许有一个位置接地,如果铁芯的接地位置超过一个,就会使铁芯停止工作,导致变压器不能正常运行。针对变压器铁芯出现多处接地的现象,可以通过对铁芯和变压器油箱上施加直流电冲击,将接地线全部烧断,为了确保接地线完全烧断,可以多次电冲击。另外就是停机,打开油箱检测,发现多余的接地线,剪除多余的接地线。
变压器接头过热。变压器在设计时就按照接头过热,自动熔断的机制进行设计,这是一种保护变压器不被烧坏的方式。但是为了让变压器在发生接头过热后,能继续恢复工作,可以用下面两种方法:
普通链接。虽然变压器的设计是过热熔断,但是变压器工作起来难免发热,因此需要对接头的过热熔断机制接头换成普通连接,这样就能保证过热也能连接,使变压器继续工作。
铜质或铝质的电线连接变压器的接头都是采用的铜材质,但是铜材质在潮湿的环境内会发生电解反应,所以同接头无法与铝接头相连接,所有可以通过给变压器加装一端铜接头一端铝接头的接线,就可以解决连接问题。

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。
