產(chǎn)品特點 Features
CBQ59電動機變頻調(diào)速箱可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,達到生產(chǎn)工藝的要求
或?qū)崿F(xiàn)節(jié)電的目的,節(jié)電率可達30%-60%,也可作為電動機軟件起控制器,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,起動平衡無沖擊電流(軟起動),電源容量大大降低,功率因數(shù)恒定,同時具備故障顯示
等各種功能.
1、過電流保護、短路保護,過電壓保護、欠電壓保護,瞬時停電保護和斷斷相保護.
2、可數(shù)字顯示頻率,轉(zhuǎn)速以及負載率或電流等.
3、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.

CBQ59 govemor is mainly used to adjust the speed of 3-phase asynchroneous motor by converting
output frequency,so as to meet with production requirements or save electrical energy up to30%-60%
Also it can be used as soft starting controller of motor,furthermore it can be combined with sensor,
sransforming device.Etc,to form speed adjusting system of closed loop.Features;ease to install and
operate,start in balance without shock current(soft starting),decrease suppliced power,constant
power factor,fault indication.
The main components of governor is chip mircroprocessor,with following protections and
performances;
1 Protection of over current,short-circuit,over voltage,under voltage,instantaneous de-
energization and phase-failure.
2 Digital or pointer indication of frequency,rotary speed,load rate andcurrent.
3 Manuually adjusting frequency is available,able to set the characteristic curve in
accordance with rotary speed accompanied by time passing,the frequency is able to be
