CBQ59電動(dòng)機(jī)變頻調(diào)速箱可通過(guò)改變其輸出頻率來(lái)調(diào)節(jié)普通三相異步電動(dòng)機(jī)的轉(zhuǎn)速,達(dá)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(dá)30%-60%,也可作為電動(dòng)機(jī)軟件起控制器,也可通過(guò)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(jiǎn)單,起動(dòng)平衡無(wú)沖擊電流（軟起動(dòng)）,電源容量大大降低,功率因數(shù)恒定,同時(shí)具備故障顯示
等各種功能.
1、過(guò)電流保護(hù)、短路保護(hù),過(guò)電壓保護(hù)、欠電壓保護(hù),瞬時(shí)停電保護(hù)和斷斷相保護(hù).
2、可數(shù)字顯示頻率,轉(zhuǎn)速以及負(fù)載率或電流等.
3、可手動(dòng)調(diào)節(jié)頻率 .可設(shè)定轉(zhuǎn)速按時(shí)間變化的工藝曲線.也可由DCS系統(tǒng)給出信號(hào)來(lái)控制其頻率.
本產(chǎn)品調(diào)速變頻器為進(jìn)口元件.柜內(nèi)還裝有電流表、電壓表、自動(dòng)空氣開關(guān)、指示燈、
交流接觸器、工頻變頻轉(zhuǎn)換開關(guān)及起動(dòng)、停止按鈕等.可根據(jù)不同用戶的工藝要求設(shè)計(jì),選擇器件及配制各種

4、鋼管或電纜布線.
5、符合GB3836-2000,IEC60079標(biāo)準(zhǔn)要求.
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
controlled as well by DCS system’s requirement,components or operating mode can be
freely chosen as possible.
4 Suitable for steelpipe and cable wiring.
5 Suitable for GB3836-2000,IEC60079 standard request.
