PG5A版氯化氢透平电气设计使用说明书（配置：ABB软启动) PG0-2-5-A PG5A版电气柜根据用户需求设计,具有下列特点; 1. 主电机启动方式采用软启动方式，选用ABB公司 PST300-600-70或PSTB370-600-70 或PSTB470-600-70型软启动器，放置在电气柜内。

2.主电机开停操作地点设计可分别选择在PLC柜（还可选择本柜或现场操作箱）、电气柜、用户备用三处操作。

3.电气油泵、油加热等辅助控制电路也设置在电气柜，其自控用PLC逻辑自控。

PG5A 版氯化氢透平电控柜有二种可供用户选择。

一种一体柜，是一个800（宽）×2100（高）×800（深）的柜体，分为电气及PLC二部分，上面500是PLC区，前后开门安装维修，下面1600是电气区，前开门安装维修强电弱电相互隔离确保安全。

另一种分体柜，有PLC柜与电气柜二个柜体，都是800（宽）×1800（高）×700（深）。

氯化氢离心压缩机无论规模大小，工艺设备上都有主机系统，氯化氢气管道系统、水冷却系统、氮气管道系统、润滑油系统五部分组成。

主机电力拖动大氯化氢透平采用高压电机。

求是公司生产小于10万吨氯化氢透平采用大功率低压电机（132、160、185、200、220、250KW）,润滑油站辅油泵(2.2 KW)及油电加热(3 KW×2)需电气控制。

要启动氯化氢透平，并保证长期安稳运行，需要设计专用电气柜。

1．主电路与主控制电路LHQ型氯化氢透平主电机分别选用132KW、160KW、185KW、200KW或220KW、250KW低压电动机，采用额定转速高二极电机。

为了保护用户电网免受主电机启动时大电流冲击，设计采用软启动方式。

软启动装置选用ABB公司新型智能化基于微处理器技术的PST或PSTB系列软启动器。

PST300－600－70型适用于常规启动132KW、160KW电机，外接方式额定电流300A。

ABB软启动器PSS系列参数设置方法软起动器是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的新颖电机控制装置，国外称为Soft Starter。

它的主要构成是串接于电源与被控电机之间的三相反并联闸管及其电子控制电路。

运用不同的方法，控制三相反并联闸管的导通角，使被控电机的输入电压按不同的要求而变化，就可实现不同的功能。

软起动器和变频器是两种完全不同用途的产品。

变频器是用于需要调速的地方，其输出不但改变电压而且同时改变频率；软起动器实际上是个调压器，用于电机起动时，输出只改变电压并没有改变频率。

变频器具备所有软起动器功能，但它的价格比软起动器贵得多，结构也复杂得多。

ABB PSS系列软启动器有3个旋转设定开关合一个2位拨动开关，对于各种不同的应用场合都能完成基本的参数设定。

1．启动曲线——设定启动时电压提升的时间说明：斜坡升压软起动。

这种起动方式最简单，不具备电流闭环控制，仅调整晶闸管导通角，使之与时间成一定函数关系增加。

其缺点是，由于不限流，在电机起动过中，有时要产生较大的冲击电流使晶闸管损坏，对电网影响较大，实际很少应用。

启动时间可在1-30秒内调整。

2．停止曲线——设定停止时间电压下降的速度说明：电机停机时，传统的控制方式都是通过瞬间停电完成的。

但有许多应用场合，不允许电机瞬间关机。

例如：高层建筑、大楼的水泵系统，如果瞬间停机，会产生巨大的“水锤”效应，使管道，甚至水泵遭到损坏。

为减少和防止“水锤”效应，需要电机逐渐停机，即软停车，采用软起动器能满足这一要求。

软起动器中的软停车功能是，晶闸管在得到停机指令后，从全导通逐渐地减小导通角，经过一定时间过渡到全关闭的过程。

停车的时间根据实际需要可在0 ~ 30s调整。

3．初始电压/限流功能——设定启动曲线的开始电压水平以及停止曲线的终止电压水平初始电压说明：30%-70%全电压范围内可调节5级限流功能说明：这种起动方式是在电动机起动的初始阶段起动电流逐渐增加，当电流达到预先所设定的值后保持恒定，直至起动完毕。

How to select the correct size DS7 Soft Starter for standard duty applications.ApplicationThe DS7 is a two phase control soft starter utilizedto accomplish motor starting using the reducedvoltage method. Typically, the motor Horsepoweror kW rating is used to determine the required sizeof the soft starter. This document addresses otherfactors that require consideration in accomplishingthe proper match of soft starter to the load.OverviewSoft starter sizing is typically determined by theHorsepower or kW rating of the motor, coupledwith the mains operating voltage. Using this infor-mation, a table or graph is consulted to determinethe minimum size of the soft starter for the appli-cation. If the application is considered to be severeduty, it is commonplace to select the next sizelarger soft starter to accommodate the higher loadcurrents.The graphs and tables published for the DS7 arebased on an inrush value of 300% FLA or 400%FLA of the motor. If the actual inrush currentapproaches a value of 400% FLA, the maximumallowable ramp times are significantly affected.Additionally, the ramp times also must be consid-ered independently, as when the ramp times areincreased even though the inrush current does notchange, the maximum allowable current capacityis reduced. When selecting the size of the DS7soft starter, Tables 1 – 4 may be used if the antici-pated ramp times are 10 seconds or less. Pleasenote that either 300% or 400% Current Limitrefers to the maximum anticipated start current interms of motor FLA (3x or 4x). The DS7 does nothave a current limiter function. If the ramp timesare expected to be longer, Tables 5 – 11 should bereviewed to ensure that the soft starter is not sub-jected to excessive current resulting in SCR failure.The size of the soft starter may be required to beincreased specifically due to a longer ramp time.NThe DS7 Soft Starter may be incorrectly sized ifNote:based solely on motor Horsepower or kW rating andmains voltage alone.Tht DS7 SNfo Soarotr rtquirts ohao sptcificaootnoiNn is givtn oN owN facoNrse:Uloimaot lNad –• the maximum inrush currentthat the soft starter will transmit anytime duringthe start process.Ramp oimt –• the expected, or required, ramptime required for the motor to achieve synchro-nous speed.2Application Paper AP03901006EEffective December 2010How to select the correct size DS7 Soft Starter for standard duty applicationseAtOn cOrpOrAtiOn Examplt 17.5HP Motor (11A FLA) @ 460V Application, Maximum Current 300% FLA @ 40oC with an estimated start ramp time of 8 seconds and 4 starts per hour.Consulting Table 1, the DS7-340SX012NO-N soft starter shows an acceptable maximum motor size of 7.5HP . Please note that Tables 1 thru 4 indicate maximum allowable start ramp times of 10 seconds @ 1 start/hr for these selections. Consulting Table 8, the maximum allowable start current is noted as 36A, and the maximum allow-able start ramp time is 8 seconds. Under these conditions, a DS7-340SX012NO-N soft starter is the appropriate selection for this application.Examplt 2With the same operating conditions as in Example 1, it is deter-mined that the ramp time must be extended to 12 seconds for the motor to achieve synchronous speed. Consulting Table 8, the maximum allowable start current for 12 seconds (noted in Table 8 as 12.1 seconds) is indicated as 30A, less than the required 33A (3 x 11 amps). Under these conditions, the DS7-340SX012NO-N soft starter would not be an appropriate selection. Table 9 for the next higher size soft starter, lists the maximum allowable start current @ 12 sec-onds (interpolating between 11.9 and 12.9 seconds) as approximately 37A. Under these new conditions, the next size higher soft starter, DS7-340SX016NO-N is the suitable choice, as the maximum allow-able start current for these conditions is sufficient for proper opera-tion.Examplt 3With the same operating conditions as in Example 1, it is deter-mined that the inrush current requires a 400% Current Limit. This operating condition will also require a larger capacity soft starter (DS7-340SX016NO-N) to accommodate the higher operating current (44 amps) during the start ramp time.ManualsRtftrtnct NumbtrDS7 Instructional Leaflet DS7 CatalogPrNgram Filts nNnt Ouolint DrawingsnNntSupporting documentationAdditional helpIn the event additional help is needed, please contact the Technical Resource Center at 1-877-ETN-CARE.

ABB软启‎动器参数设‎置方法软起动器是一种集电‎机软起动、软停车、轻载节能和‎多种保护功‎能于一体的‎新颖电机控‎制装置，国外称为S‎o ft Start‎e r。

它的主要构‎成是串接于‎电源与被控电机‎之间的三相‎反并联闸管‎及其电子控制电路。

运用不同的‎方法，控制三相反‎并联闸管的‎导通角，使被控电机‎的输入电压‎按不同的要‎求而变化，就可实现不‎同的功能。

软起动器和‎变频器是两种完全‎不同用途的‎产品。

变频器是用于需要‎调速的地方‎，其输出不但‎改变电压而‎且同时改变‎频率；软起动器实‎际上是个调‎压器，用于电机起‎动时，输出只改变‎电压并没有‎改变频率。

变频器具备‎所有软起动‎器功能，但它的价格‎比软起动器‎贵得多，结构也复杂‎得多。

ABB PSS系列‎软启动器有3个旋转‎设定开关合‎一个2位拨‎动开关，对于各种不‎同的应用场‎合都能完成‎基本的参数‎设定。

1．启动曲线——设定启动时‎电压提升的‎时间说明：斜坡升压软‎起动。

这种起动方‎式最简单，不具备电流‎闭环控制，仅调整晶闸‎管导通角，使之与时间‎成一定函数‎关系增加。

其缺点是，由于不限流‎，在电机起动‎过中，有时要产生‎较大的冲击‎电流使晶闸‎管损坏，对电网影响‎较大，实际很少应‎用。

启动时间可‎在1-30秒内调‎整。

2．停止曲线——设定停止时‎间电压下降‎的速度说明：电机停机时‎，传统的控制‎方式都是通‎过瞬间停电‎完成的。

但有许多应‎用场合，不允许电机‎瞬间关机。

例如：高层建筑、大楼的水泵‎系统，如果瞬间停‎机，会产生巨大‎的“水锤”效应，使管道，甚至水泵遭‎到损坏。

为减少和防‎止“水锤”效应，需要电机逐‎渐停机，即软停车，采用软起动‎器能满足这‎一要求。

软起动器中‎的软停车功‎能是，晶闸管在得‎到停机指令‎后，从全导通逐‎渐地减小导‎通角，经过一定时‎间过渡到全‎关闭的过程‎。

停车的时间‎根据实际需‎要可在0 ~ 30s调整‎。

供应ABB软启动器参数设置方法软启动器应用特点及选型软启动器工作原理软启动器采用三相反并联晶闸管作为调压器，将其接入电源和电动机定子之间。

这种电路如三相全控桥式整流电路，主电路图见图 1.使用软启动器启动电动机时，晶闸管的输出电压逐渐增加,电动机逐渐加速，直到晶闸管全导通，电动机工作在额定电压的机械特性上，实现平滑启动，降低启动电流，避免启动过流跳闸。

待电机达到额定转数时，启动过程结束,软启动器自动用旁路接触器取代已完成任务的晶闸管，为电动机正常运转提供额定电压,以降低晶闸管的热损耗，延长软启动器的使用寿命，提高其工作效率，又使电网避免了谐波污染.软启动器同时还提供软停车功能，软停车与软启动过程相反，电压逐渐降低,转数逐渐下降到零，避免自由停车引起的转矩冲击软启动器的选用 (1）选型：目前市场上常见的软启动器有旁路型、无旁路型、节能型等。

根据负载性质选择不同型号的软启动器。

旁路型:在电动机达到额定转数时，用旁路接触器取代已完成任务的软启动器,降低晶闸管的热损耗,提高其工作效率。

也可以用一台软启动器去启动多台电动机。

无旁路型:晶闸管处于全导通状态,电动机工作于全压方式，忽略电压谐波分量，经常用于短时重复工作的电动机. 节能型：当电动机负荷较轻时，软启动器自动降低施加于电动机定子上的电压，减少电动机电流励磁分量，提高电动机功率因数. （2) 选规格:根据电动机的标称功率，电流负载性质选择启动器,一般软启动器容量稍大于电动机工作电流，还应考虑保护功能是否完备，例如：缺相保护、短路保护、过载保护、逆序保护、过压保护、欠压保护等. 3 Alt48软启动器的特点 Alt48软启动器启动时采用专利技术的转矩控制.转矩斜坡上升更快速,损耗更低。

具有电动机和软启动器综合保护功能,能全时连续检测电机电流,提供电机可靠和完整保护，这种保护功能在启动结束旁路后仍能起作用，这是其它软启动器都不具备的。

Alt48在保持加速力矩的同时，实时计算定子和转子的功率。

（2）选规格：根据电动机的标称功率，电流负载性质选择启动器，一般软启动器容量稍大于电动机工作电流，还应考虑保护功能是否完备，例如：缺相保护、短路保护、过载保护、逆序保护、过压保护、欠压保护等。

3 Alt48软启动器的特点 Alt48软启动器启动时采用专利技术的转矩控制.转矩斜坡上升更快速，损耗更低。

具有电动机和软启动器综合保护功能,能全时连续检测电机电流,提供电机可靠和完整保护，这种保护功能在启动结束旁路后仍能起作用，这是其它软启动器都不具备的. Alt48在保持加速力矩的同时，实时计算定子和转子的功率。

因此，UltraPLC使用正交或pprx等于每转个计数，交流和步进电机可能都是可靠的，因为它们都是无刷的。

或在机床运行过程中被置为OFF时就会发生SV0401报警，这是厂家的书面说明，其实就是数控机床准备就绪信号没准备，或者加工的时候准备就绪信号断开了，就出现此报警，也可能因为发生了其他伺服报警，比如当出现SV0449报警时。

设置位置，例如，如果要对号I/O引脚施加某些功能，则可以根据下表找到该信号的相关参数以及设置窗口中的位置，然后输入["作为设置值，选择电动机，一方面，他们使用的物理尺寸是非标准的，而Efilte规格充其量只是个粗略的-更不用说要考虑的额外费用了。

其周期决定于kf，振幅决定于ku,中曲线①。

abb软启动装置晶闸管损坏维修有质保：abb软启动装置晶闸管损坏维修电源电压不足。

这主要是因为电源变压器的容量不够大。

如果负载很重，很容易报告由于低压引起的欠压故障。

根据国家标准，进线电压的下限为380×0.9 =342V。

电压由内部总线采样。

342V时的DC平均电压为342×1.35 = 462V。

例如作为笔记本电脑电源的使用，起动机和电动***的启动用电源等，近作为电动***的行驶用电源本身也可以使用，板块结构更灵活尽管原则上结合硬板和软板可以使用各种级联结构，但是如果不仔细考虑PCBPCB制造商的生产步骤和材料性能。
