西門子3RW5515-1HA05     西門子3RW44軟啟動(dòng)器   產(chǎn)品簡(jiǎn)介：

SIRIUS 3RW44 電子式電機(jī)軟起動(dòng)器是為簡(jiǎn)單的起動(dòng)條件而設(shè)計(jì)的。一旦出現(xiàn)起動(dòng)負(fù)載較大或者起停頻率增加的情況，就必須選擇較大額定值的產(chǎn)品。
3RW44 軟起動(dòng)器可以用在電壓高達(dá) 600 V AC 的隔離電源網(wǎng)絡(luò)（IT 系統(tǒng)）中。
若起動(dòng)時(shí)間較長(zhǎng)，建議在電機(jī)中使用 PTC 傳感器。轉(zhuǎn)矩控制、泵的停止以及直流制動(dòng)減速停止等模式也是這種情況，因?yàn)樵谶@些模式下的斜坡減速時(shí)間內(nèi)，與自由斜坡減速相比會(huì)有額外的電流負(fù)載。
不允許在電機(jī)饋電線內(nèi) SIRIUS 3RW 軟起動(dòng)器和電機(jī)之間使用電容性元件（如，不能使用無(wú)功補(bǔ)償設(shè)備）。此外，無(wú)論是用于無(wú)功補(bǔ)償?shù)撵o態(tài)系統(tǒng)，還是動(dòng)態(tài) PFC（功率因數(shù)校正），在啟動(dòng)時(shí)和軟起動(dòng)器斜降時(shí)都不能并行操作。這對(duì)于防止補(bǔ)償設(shè)備和/或軟起動(dòng)器發(fā)生故障來(lái)說(shuō)十分重要。
主電路的所有元件（比如熔斷器和控制器）應(yīng)該按照在加載短路時(shí)直接起動(dòng)的情況下相應(yīng)的進(jìn)行選型。熔斷器和分?jǐn)嘌b置必須單獨(dú)訂購(gòu)。
3RW44 軟起動(dòng)器中已集成一個(gè)旁路觸點(diǎn)系統(tǒng)和固態(tài)過(guò)載繼電器，無(wú)需單獨(dú)訂購(gòu)。
在選擇斷路器（選擇脫扣器）時(shí)，必須考慮用于起動(dòng)電流的諧波分量負(fù)載。

3RW44 電子軟啟動(dòng)器是為正常起動(dòng)而設(shè)計(jì)的。一旦出現(xiàn)起動(dòng)負(fù)載較大或者起動(dòng)頻率增加的情況，就必須選擇較大額定值的產(chǎn)品。
若起動(dòng)時(shí)間較長(zhǎng)，建議在電機(jī)中使用 PTC 傳感器。這也適用于軟停止、泵停止和直流制動(dòng)等滑行方法，因?yàn)樵谶@些模式下的減速時(shí)間內(nèi)，相對(duì)于滑行停止，將會(huì)產(chǎn)生額外的電流負(fù)載。
軟啟動(dòng)器和電機(jī)之間的電機(jī)饋線不得包含任何電容性元件（例如補(bǔ)償系統(tǒng)）。有源濾波器不得與軟啟動(dòng)器結(jié)合使用。
主電路所有元件（如熔斷器和開關(guān)裝置）的規(guī)格設(shè)計(jì)應(yīng)滿足直接起動(dòng)要求并符合局部短路情況且必須單獨(dú)訂購(gòu)。
在選擇電機(jī)啟動(dòng)器保護(hù)器（選擇脫扣器）時(shí)，必須考慮起動(dòng)電流的諧波分量負(fù)載。

重載起動(dòng)應(yīng)用實(shí)例（20 級(jí)）：

要實(shí)現(xiàn)軟起動(dòng)器設(shè)計(jì)，必須了解并考慮應(yīng)用的起動(dòng)時(shí)間（起動(dòng)等級(jí)）。起動(dòng)時(shí)間越長(zhǎng)意味著軟起動(dòng)器的晶閘管上的熱負(fù)載就越大。3RW44 軟起動(dòng)器可在正常起動(dòng)條件 (CLASS 10)、40 °C 環(huán)境溫度、開關(guān)頻率為固定值的情況下連續(xù)工作。還可在“電源單元的技術(shù)數(shù)據(jù)”一章中找到這些值。如果與這些數(shù)據(jù)存在偏差，可能需要加大起動(dòng)器的尺寸。

由于 SIRIUS 3RW44 軟啟動(dòng)器可適用的應(yīng)用范圍很廣，因此可以選擇不同起動(dòng)功能?？舍槍?duì)各個(gè)特定的應(yīng)用對(duì)電機(jī)起動(dòng)進(jìn)行優(yōu)化調(diào)整。

使用電壓斜坡可通過(guò) SIRIUS 3RW44 軟啟動(dòng)器實(shí)現(xiàn)最簡(jiǎn)單的軟起動(dòng)。在可調(diào)節(jié)起動(dòng)時(shí)間內(nèi)，電機(jī)端子電壓會(huì)從可參數(shù)化的起動(dòng)電壓升至線電壓。該起動(dòng)模式在快速起動(dòng)菜單中預(yù)設(shè)。
起動(dòng)電壓：
起動(dòng)電壓決定了電機(jī)的起動(dòng)轉(zhuǎn)矩。起動(dòng)電壓越低，擰緊扭矩和起動(dòng)電流也越低。選擇起動(dòng)電壓時(shí)，應(yīng)能在起動(dòng)命令傳入軟啟動(dòng)器后使電機(jī)立即平穩(wěn)起動(dòng)。
起動(dòng)時(shí)間：
起動(dòng)時(shí)間的長(zhǎng)度決定了電機(jī)電壓從參數(shù)化的起動(dòng)電壓增至電源電壓所需的時(shí)間。這會(huì)影響電機(jī)的加速轉(zhuǎn)矩，這一轉(zhuǎn)矩將在斜坡上升工作期間驅(qū)動(dòng)負(fù)載。起動(dòng)時(shí)間越長(zhǎng)，電機(jī)斜坡上升期間的加速轉(zhuǎn)矩就越小。由此，電機(jī)的起動(dòng)過(guò)程就越長(zhǎng)、越平穩(wěn)。選擇起動(dòng)時(shí)間時(shí)，應(yīng)能使電機(jī)在此時(shí)間內(nèi)達(dá)到其額定轉(zhuǎn)速。如果選擇的時(shí)間過(guò)短（例如，起動(dòng)時(shí)間在電機(jī)成功起動(dòng)之前就結(jié)束），則在結(jié)束的這一時(shí)刻，起動(dòng)電流會(huì)很高，將達(dá)到此轉(zhuǎn)速下直接起動(dòng)的電流值。在這種情況下，軟啟動(dòng)器可以通過(guò)內(nèi)部過(guò)載保護(hù)功能自行關(guān)閉，并進(jìn)入故障模式。
起動(dòng)時(shí)間：
可以使用“最長(zhǎng)起動(dòng)時(shí)間”(Maximum starting time) 參數(shù)來(lái)確定驅(qū)動(dòng)器完成起動(dòng)所必需的時(shí)間。如果在經(jīng)過(guò)時(shí)間間隔后驅(qū)動(dòng)器未處于額定運(yùn)行條件下，則起動(dòng)過(guò)程將被中斷，并會(huì)生成一條故障消息。
內(nèi)部起動(dòng)識(shí)別：
軟啟動(dòng)器具備內(nèi)部起動(dòng)識(shí)別功能。如果設(shè)備識(shí)別出電機(jī)完全起動(dòng)，則內(nèi)部旁路接觸器會(huì)吸合，晶閘管將被橋接。如果在經(jīng)過(guò)所設(shè)置的起動(dòng)時(shí)間之前執(zhí)行了此起動(dòng)識(shí)別過(guò)程，則斜坡被中斷，電機(jī)電壓會(huì)立即升高到 100% 的線電壓，內(nèi)部旁路接觸器隨后吸合。

電流限制與電壓斜坡或轉(zhuǎn)矩控制起動(dòng)模式相結(jié)合
啟動(dòng)器借助集成電流互感器連續(xù)測(cè)量相電流（電機(jī)電流）。
可以在電機(jī)啟動(dòng)時(shí)在軟啟動(dòng)器上設(shè)置電流限值。
將“電壓斜坡 + 電流限制”(voltage ramp + current limiting) 或“轉(zhuǎn)矩控制 + 電流限制”(torque control + current limiting) 選作起動(dòng)模式并在相應(yīng)的參數(shù)中輸入數(shù)值后，可激活電流限制。
在啟動(dòng)期間，相電流會(huì)被限制為設(shè)定的值，直至低于該值。在起步期間，電流限值上會(huì)疊加一個(gè)設(shè)定的起步脈沖。
電流限值：
電流限值被設(shè)置為電機(jī)額定電流與啟動(dòng)期間所需電流之間的比例系數(shù)。達(dá)到選擇的電流限值后，軟啟動(dòng)器將減小或控制電機(jī)電壓，以防電流超出所設(shè)置的電流限值。設(shè)置的電流限值必須足夠高，以確保電機(jī)中生成的轉(zhuǎn)矩足以使電機(jī)加速至額定轉(zhuǎn)速?？梢詫⒃撾娏飨拗档牡湫椭导俣殡姍C(jī)額定工作電流 (Ie) 的三到四倍。
斜坡上升檢測(cè)：
軟啟動(dòng)器具備內(nèi)部起動(dòng)識(shí)別功能。如果其檢測(cè)到電機(jī)斜坡上升，則電機(jī)電壓會(huì)立即增至 100% 的線電壓。內(nèi)部旁路接觸器會(huì)吸合，晶閘管將被橋接。

轉(zhuǎn)矩控制和泵停止：
設(shè)置“受轉(zhuǎn)矩控制的停止”和“泵停止”時(shí)，負(fù)載的滑行停止（或自然停止）將減速進(jìn)行。如果需要防止負(fù)載突然停止，應(yīng)設(shè)置該功能。典型示例包括質(zhì)量慣性值較小或者反轉(zhuǎn)矩較高的應(yīng)用。
為了確保在停止過(guò)程中實(shí)施轉(zhuǎn)矩控制，應(yīng)在所選參數(shù)組中使用“設(shè)置”(Setting) 菜單項(xiàng)輸入軟啟動(dòng)器所連電機(jī)的電機(jī)數(shù)據(jù)。
滑行停止時(shí)間和停止轉(zhuǎn)矩
通過(guò)軟啟動(dòng)器上的“滑行停止時(shí)間”(Coast-down time) 參數(shù)，可在移除“ON”命令后，仍應(yīng)為電機(jī)供電的時(shí)間。在該滑行停止時(shí)間內(nèi)，電機(jī)中產(chǎn)生的轉(zhuǎn)矩將連續(xù)線性地降至設(shè)定的停止轉(zhuǎn)矩，相應(yīng)的應(yīng)用將平穩(wěn)停止。
泵停止：
在泵應(yīng)用中，如果驅(qū)動(dòng)器在未采用泵停止的情況下突然停止，則會(huì)發(fā)生所謂的水錘現(xiàn)象。水錘現(xiàn)象是由泵突然失速以致泵中產(chǎn)生壓差而造成。這會(huì)產(chǎn)生噪聲，并會(huì)對(duì)管道系統(tǒng)及其內(nèi)安裝的翻板閥和其它閥門產(chǎn)生機(jī)械影響。
