BKX52电动机变频调速箱可通过改变其输出频率来调节普通三相异步电动机的转速，以达到生产工艺的要求，或实现节电的目的，节电率可达
30%～60%，也可作为电动机软起动控制器，也可通过传感器、变送器等控制电路组成闭环调速系统。安装操作简单，起动平衡无冲击电流（软
起动），电源容量大大降低，功率因数恒定，同时具备鼓掌显示等各种功能。
由于调速变频器的核心器件是单片微机，因此具有很强的功能：
1. 过电流保护、短路保护、过电压保护、欠电压保护、瞬时停电保护和端相保护。
2. 可数字显示或指示或指针显示频率、转速以及负载率或电流等。
3. 可手动调节频率。可设定转速按时间变化的工艺曲线。也可由DCS系统给出信号来控制其频率。
本产品调速频率为进口元件。柜内还装有电流表、电压表、自动空气开关、指示灯、交流接触器、工频变频转换开关及起动、停止按钮等。可
根据不同拥护的工艺要求设计，选择器件及配制各种适当的操作方法。
4. 钢管或电缆布线。
5. 符合GB3836-2000、IEC60079, GB12476.1-2000、IEC61241标准要求。
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 system's 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 user's 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
