性能特點(diǎn)

控制系統(tǒng)采用H7四象限變頻器和可編程控制技術(shù)，具有控制精度高、運(yùn)行穩(wěn)定、制動(dòng)效果好、節(jié)能率高等特點(diǎn)。對(duì)傳統(tǒng)的門(mén)、適合于橋式起重機(jī)所有電力拖動(dòng)系統(tǒng)的控制柜配套和技術(shù)改造，使門(mén)、橋式起重機(jī)實(shí)現(xiàn)平穩(wěn)操作，提高運(yùn)行效率，改善超負(fù)荷作業(yè)，消除起制動(dòng)沖擊，減少電氣維護(hù)，降低電能消耗，提高功率因數(shù)延長(zhǎng)使用壽命等均可取得良好實(shí)效。同時(shí)該系統(tǒng)還具有過(guò)電流、過(guò)電壓、欠電壓和輸入缺相保護(hù)，以及變頻器超溫、超載、超速、回饋制動(dòng)單元過(guò)熱、故障保護(hù)、電動(dòng)機(jī)故障保護(hù)等，具有如下顯著特點(diǎn)：

1、調(diào)速范圍寬，可實(shí)現(xiàn)多種速度選擇；

2、軟啟動(dòng)、軟停止的功能降低了機(jī)械傳動(dòng)沖擊，可明顯改善鋼結(jié)構(gòu)的承載性能，延長(zhǎng)了起重機(jī)的使用壽命；

3、高集成度組件及高可靠性低壓電器，有效解決原電氣系統(tǒng)接線復(fù)雜問(wèn)題，不僅降低了系統(tǒng)故障率，而且易維護(hù)；

4、電動(dòng)機(jī)在零速時(shí)，能全力矩輸出，即使制動(dòng)器松動(dòng)或失靈時(shí)，也不會(huì)出現(xiàn)重物下滑，確保系統(tǒng)安全可靠；

5、具有快速的動(dòng)態(tài)響應(yīng)，不會(huì)出現(xiàn)溜鉤并真正實(shí)現(xiàn)“零速交叉”功能；

6、負(fù)荷重量測(cè)控儀并配以相應(yīng)軟件，起升速度可隨負(fù)荷重量變化自切換，實(shí)現(xiàn)“輕載快速，重載慢速”的作業(yè)要求；
