BKX52電動機變頻調速箱可通過改變其輸出頻率來調節普通三相異步電動機的轉速，以達到生產工藝的要求，或實現節電的目的，節電率可達
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調速系統。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，功率因數恒定，同時具備鼓掌顯示等各種功能。
由于調速變頻器的核心器件是單片微機，因此具有很強的功能：
1. 過電流保護、短路保護、過電壓保護、欠電壓保護、瞬時停電保護和端相保護。
2. 可數字顯示或指示或指針顯示頻率、轉速以及負載率或電流等。
3. 可手動調節頻率。可設定轉速按時間變化的工藝曲線。也可由DCS系統給出信號來控制其頻率。
本產品調速頻率為進口元件。柜內還裝有電流表、電壓表、自動空氣開關、指示燈、交流接觸器、工頻變頻轉換開關及起動、停止按鈕等。可
根據不同擁護的工藝要求設計，選擇器件及配制各種適當的操作方法。
4. 鋼管或電纜布線。
5. 符合GB3836-2000、IEC60079, GB12476.1-2000、IEC61241標準要求。
BQX52 governor 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 to 30% 60%. Also it can be as soft starting controller of motor, furthermore it can be combined with sensor,
transforming 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 supplied power, constant power factor, fault indication.
The main components of governor is chip microprocessor, 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 and current.
3. Manually 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 systems sending adjusting signal.
The main components are imported. Inside is arranged ammeter, voltmeter, air circuit breaker, indicator, AC contactor, conversion switch, and buttons for starting or stopping. According to users requirement, components or operating modes can be freely chosen as possible.
4. Suitable for both steel pipe and cable wiring.
5. Suitable for GB3836-2000、 IEC60079、GB12476.1-2000、IEC61241 standard request
