CACR-SR01AB1ER-Y1可用變頻器作為電機(jī)的起動裝置,降低了電機(jī)的起動電流,因而就可以降低應(yīng)急電源的容量,使應(yīng)急CACR-SR01AB1ER-Y1的投資成本進(jìn)一步降低。
2 變頻器在消防應(yīng)急電源EPS系統(tǒng)中應(yīng)用原理:
2.1.此系統(tǒng)包括:
充電電路 ,蓄電池組,變頻器及控制電路,濾波電路,隔離變壓器,接觸器或晶閘管,控制電路,各種負(fù)載等。
2.2工作原理
三相動力變頻應(yīng)急電源供電對象和控制對象是電動機(jī),那么設(shè)計(jì)思路要圍繞電動機(jī)的特性而設(shè)計(jì),要考慮電機(jī)的啟動、調(diào)速、停止,要避免電機(jī)起動過程中的沖擊電流。當(dāng)三相輸入市電,正常時(shí)經(jīng)整流后給逆變器提供直流電,同時(shí)經(jīng)充電器對蓄電池組充電,蓄電池組處于全浮充狀態(tài),蓄電池組的電壓比變頻器支流環(huán)節(jié)的電壓略低,比如,變頻器直流環(huán)節(jié)的電壓為513V,蓄電池組的電壓為500V;當(dāng)三相輸入斷電或異常時(shí),自動轉(zhuǎn)換由蓄電池組給
