BA控制系统的操作说明书
BA控制系统的操作说明书一、概述本BA系统是采用思迈特的控制器、OPC和西门子组态软件WINCC组成。
思迈特控制器做控制单元，OPC做数据服务端，WINCC做人机对话窗口。
在本指南中着重讲述操作系统的使用及控制要求。
二、系统介绍本操作系统是用WINCC组态软件制作，在本系统中主要分为：控制系统网络图、冷热水群控系统、空调风柜系统、排风系统、地下室通风系统、；数据曲线、报警记录和用户权限。
用户权限是用来确认操作身份，根据不同权限给予不同的操作。
在本操作系统中设置一个管理员身份，身份确认后放才能设置控制参数。
其他界面是对相应的设备操作和显示设备运行状态。
三、系统界面及操作介绍每个子系统里相对的设备的操作和状态显示，每种设备的控制工艺和要求不同而进行不同的操作。
在此针对每个子系统做一一说明。
1、群控系统群控系统是整个空调提供冷源的设备，在群控系统主要是冷水机组、冷却塔、冷冻泵和冷却泵组成。
也就是整个系统的核心。
冷水机组冷水机组主要由冷机、冷冻水泵、冷却水泵和冷却塔、等组成。
中央空调系统的控制分冬季控制和夏季的控制。
冬季主要是供暖，夏季主要是制冷。
在本系统中只有夏季模式的控制，也就是本系统只提供制冷。
在本BA 系统中把冷源部分分成2个系统即冷源一和冷源二。
冷源系统流程图如下所示：✓冷源机组的控制：⏹监控内容监控设备数量监控内容程序最优开关控制，手自动状态运行状态，故障状态，水流冷水机组4台开关冷冻泵水泵5台程序最优开关控制, 运行状态，故障状态，手自动状态冷却水泵5台程序最优开关控制, 运行状态，故障状态，手自动状态电动蝶阀12台程序最优开关控制, 运行状态，故障状态，手自动状态冷却塔4台程序最优开关控制, 运行状态，故障状态，手自动状态⏹启停顺序控制冷冻水系统启动顺序：冷却塔进出口蝶阀→冷却塔风机→冷却电动蝶阀→冷却水泵→冷冻机进出口蝶阀→冷冻水泵→冷水机组。
冷冻水系统关机顺序：冷水机→冷却塔风机→冷却水泵→冷却塔进出口蝶阀→冷机冷却蝶阀→冷冻水泵→冷冻蝶阀（这样的关机顺序能最大限度利用剩余的冷源）。

ATS技术操作规程一.送电前检查1.检查接线是否正确检查ACP(辅助控制板)与BA或UA(控制器)之间9#.10#连接端子对应是否正确;检查ACP上P25M与断路器之间接线是否正确(详见“ATS接线”单页)2.检查BA或UA控制器顶部17#.18#；20#.21#端子是否安装，17#.18#;20#21#已分别短封好;3.检查断路器电操左下方的手动(manu)和电动(auto)切换拨钮是否在“auto”位置;4.检查电操与BA或UA控制器的操作电压是否一致(220V~或380V~);5. 检查ATS装置无异物;6.检查ACP上P25M是否已在合闸位置。
二.操作试验1.预设电源转换时间: 通过控制器右上方时间整定钮调整;2.将BA或UA控制器上的选择开关置于“STOP”位置，将ACP上“N(工作电源)”及“R(备用电源)”侧P25M分别合闸（两台断路器电操储能）。
3.将BA或UA控制器上的选择开关转到“auto”位, N断路器合闸,BA或UA“N”、“R”侧ON或OFF指示断路器的合分状态。
观察控制器指示与断路器电操上的ON. OFF位置应一致;4.将ACP上N侧P25M开关分断模拟电源故障, 此时N侧断路器分断；R侧断路器合闸（系统自动转换到备用电源R侧）; 合上N侧开关,电源应自动恢复到主电源（N）侧合闸---自投自复功能;5.将N侧断路器下端的故障试验推杆按入（模拟负荷故障）,N侧断路器断开BA或UA控制器的N侧Fault指示灯亮(红色),电源并不转换到备用侧; 手动拨N侧断路器电操的储能手柄2次,（N侧断路器储能、合闸）故障复位,控制器N侧Fault指示灯灭, 恢复原始状态;6.将BA或UA控制器选择开关置“R”位, 则ATS强制在备用电源侧运行; 同样再置“N”位, ATS强制在工作电源运行,此操作过程中,控制器电源指示均正常;7.将选择开关置“manual /stop”位, 控制器指示灯全部灭,两台断路器均处于断开位置（储能状态）此时可手动操作:8.将电操手、电动切换钮置“manual”位, 两台开关均手动储能, 按电操的手动合分按钮,合N侧,电操指示ON位; 若再合R侧,则备用电源侧无法合闸,说明该装置具有机械联锁功能。

双电源自动转换开关说明书
双电源自动转换开关说明书相信大家一定都购买过双电源自动转换开关，顾名思义它是在用电突然断电时通过双电源切换开关，自动连接到备用的电源上，使我们的运作不至于停断，仍能继续运作。
这种开关在我们生活的很多地方都有用到，许多公司和小区都有，那么让装修界为您具体的讲解通过双电源切换开关的原理以及说明书。
双电源自动切换开关电器主要用在紧急供电系统，将负载电路从一个电源自动换接至另一个(备用)电源的开关电器，以确保重要负荷连续、可靠运行。
因此，常常应用在重要用电场所，其产品可靠性尤为重要。
转换一旦失败将可能造成以下二种危害之一，其电源间的短路或重要负荷断电(甚至短暂停电)，其后果都是严重的，这不仅仅会带来经济损失(使生产停顿、金融瘫痪)，也可能造成社会问题(使生命及安全处于危险之中)。
因此，工业发达国家都把自动转换开关电器的生产、使用列为重点产品加以限制与规范。
双电源自动切换开关一般由两部分组成：开关本体(ats)+控制器。
而开关本体(ats)又有pc级(整体式)与cb级(断路器)之分,双电源自动转换开关电器(atse)质量的好坏关键取决于开关本体(ats)。
1.pc级ats：一体式结构(三点式)。
它是双电源切换的专用开关，具有结构简单、体积小、自身连锁、转换速度快(0.2s内)、安全、可靠等优点，但需要配备短路保护电器。
2.cb级ats：配备过电流脱扣器的ats，它的主触头能够接通并用于分断短路电流。
它是由两台断路器加机械连锁组成，具有短路保护功能控制器的工作状况控制器主要用来检测被监测电源(两路)工作状况，当被监测的电源发生故障(如任意一相断相、欠压、失压或频率出现偏差)时，控制器发出动作指令，开关本体则带着负载从一个电源自动转换至另一个电源，备用电源其容量一般仅是常用电源容量的20%~30%。
图1是典型ats应用电路。
控制器与开关本体进线端相连。
控制器的优点控制器一般应有非重要负荷选择功能。
控制器也有两种形式：一种由传统的电磁式继电器构成;另一种是数字电子型智能化产品。

系统设置灯亮：控制器处于参数设置状态； 消防灯亮：接收到火灾报警信号。
2、操作程序： 2.1、 键盘操作：2.1.1、打开进线柜柜门，在内部（WATSN ）断路器上将手动一自动开关置于“自动位置”，闭合柜门。
2.1.2、自动操作：将控制器设为互为备用工作方式（设置控制器参数第7项为NA ，并通过回车键切换为自动工作方式），通电后，如果常用电源正常，开关将自动使常用电源断路器闭合。
如果常用电源不正常，常用电源断路器断开，备用电源断路器闭合。
2.1.3、强制切换操作：通过回车键进行自动/手动强制方式的切换，当处于手动强制状态时，强制切换灯亮，然后可以通过▲键使常用电源合；通过▼键使备用电源合；通过OFF 键在无NB/RB 报警时，使开关置于 0位。
