目前的电梯绝大多数为变频调速电梯,而电梯应急电源包含有整流、逆变、电池组及检测等几个组成部分,从结构上看二者都具有整流、逆变等环节,浪费设备资源。对VVVF电梯的应急电源进行了优化设计,优化设计后的体积和质量会有大幅度减小,且增加了避免空梯施救和施救时系统冲击的功能,使应急电源的性能价格比有大幅度提高。在无机房电梯日趋增加的今天,其推广和应用前景看好。

除鳞水压控制方式

摘要：为了解决太钢热连轧带钢高压除鳞水压控制中存在的问题，通过研究生产工艺，改变了除鳞泵最小流量阀和蓄势器最低液面阀控制方式，即最小流量阀采用独特的平衡室温度控制方式，最低液面阀采用独特的蓄势器水罐液位、气罐压力和总管出水压力联锁控制方式。实践表明，除鳞水压控制方式的改进解决了除鳞系统管网出水压力波动较大的问题，增强了系统除鳞能力和稳定性，从而提高了热连轧带钢工艺表面除鳞质量。1785-KE

多功能天车电气系统 PLC

摘要：阐述了铝电解多功能天车的电气控制系统的组成，针对多功能天车断线故障、失控、吊线盒和司机室回转电机存在的问题进行电气系统改造。彻底消除了事故隐患，提高系统的可靠性，保证了天车的安全平稳运行。

包头铝业股份公司电解四公司选用200KA大型预焙电解槽，设计年产量为10万t，前4.8万t于2002年7月投入运行。电解车间分南、北两个厂房，共4台高位电解多功能天车。其中两台大连起重矿山机械有限公司设计、制造的多功能天车，在电控系统中采用了PLC控制、交流变频器等先进技术，实现了天车的各种功能自动控制，但在运行中也出现了一些问题如天车失控，天车电气系统故障率高等,影响电解生产的正常进行。电解四公司技术人员针对存在的问题进行了改造。

一、PLC系统组成

多功能天车的原PLC控制系统选用美国AB公司的SLC500系列，系统由一个主站和一个从站组成，其中主站设在主梁的A1柜内，从站在工具车的A4柜内。主站和从站之间采用DH+通信电缆联接（双绞两芯屏蔽电缆），由主站的SN扫描模块与从站的ASB适配器模块之间进行通信。主站和从站构成分别见表1、表2。通信电缆为1784-PCM6，地址分配见表3。

桥式起重机(天车)是一种用来起吊、放下和搬运重物、并使重物在一定距离内水平移动的起重、搬运设备，在生产过程中有着重要应用。5吨桥式起重机，原设备电气驱动系统分为起重机升降、小车、大车三部份。其中起重机升降由一台13kW的绕线式异步电动机驱动，大车由两台4 kW绕线式异步电动机、小车由一台2.5 kW绕线式异步电动机驱动。在原传动控制中，采用转子串接电阻的调速方式.由于工作环境差,粉尘和有害气体对电机的集电环、电刷和接触器腐蚀性大，加上工作任务重,实际过载率高,由于冲击电流偏大,容易造成电动机触头烧损、电刷冒火、电动机及转子所串电阻烧损和断裂等故障, 影响现场生产和安全,工人维修量和产生的维修费用也很高审核编辑（）
