產(chǎn)品特點 Features
1.鋁合金外殼或鋼板焊接,表面噴塑;
2.內(nèi)裝富士、西門子或施耐德等公司生產(chǎn)的變頻器、斷路器、信號燈等元件
3.它主要通過改變其輸出頻率來調(diào)節(jié)普通三相異步電動機的轉(zhuǎn)速,
以達(dá)到生產(chǎn)工藝要求或?qū)崿F(xiàn)節(jié)電的目的,
節(jié)電率可達(dá)30%~60%,也可作為電動機軟起動控制器,也可通過傳感器、變送器等控制電路組成閉環(huán)調(diào)速系統(tǒng),安裝操作簡單,功率因數(shù)恒定,同時具備故障顯示等各種功能;
4.具有過電流、短路、過電壓、欠壓、斷相等多種保護(hù),可數(shù)字顯示頻率、轉(zhuǎn)速以及負(fù)載率或電流等,可手動調(diào)節(jié)頻率,可
設(shè)定轉(zhuǎn)速按時間變化的工藝曲線,也可由DCS系統(tǒng)給出信號來控制其頻率;
5.鋼管或電纜布線。
1.Enclosure
is cast with aluminium alloy, or welded by steel plate, surface is sprayed with
plastic, fine outline
2.Built-in frequency converter, circuit breakers,
signal lamps etc of FWI ro sehneider
3.It can adjust the rotate apeed of
three phase asynchronism motor by changing output frequency, percent of energy
servingcan reach 30%-60%, it also can be used as motor soft start controller,
the transducer, transmission are composed a sealingtiming system, simple digital
operation, power factor is invariable and with many functions, like error
displaying
4.With protection of over current, short circuit, over voltage,
short voltage and loss phase, and adjust the frequency, bymanual the craftwork
curve can be set according to rotating speed changing with time transfering, the
DCS system also cansend out signal to control the frequecy
5.Wiring with
steel tube or cable.
