explosion-proof frequency-conversion governor
Application

1.Can be used in Zone 1 and Zone 2 dangerous places.
2.Can be used in IIA IIB groups explosive atmosphere.

Features
1.BQP motor adjustable frequency governor box can meet the craft request or energy-saving aim by changing the output freq uency to adjust roate velocity of ordinary three-phase asynchronous motor. The energy-saving ratio can achieve 30%-60%. The governor box can be used as the soft starter controller of motor, the governor box can control the soft starter controller of motor,the governor box can control the circuit into closedloop governing system through sensor, transformer, with easy mounting, stable start without rush current , lower power capacity, consistent power factor and matter indicating functions.
The core of adjustable frequency governor is single-chip microcomputer, it has the following functions:
2.With over current protection, short circuit protection over voltage protection, voltage abscent protection, voltage absent protection, instant power lack-protection and phase failure protection etc.functions.
3.With digital indicator function of frequency, rotating velocity or load ratio od current etc.
4.With manual adjusting frequency function.The craft curve of time controlled rotating velocity can be setted, or the frequency can be controlled by the DCS singal.
The governor frequency converter is imported. Inside the box are ammeter, voltmeter, automatic air switch, indicator, AC contactor,power frequency adjusting switch and start, stop buttons etc. The box can be made by request.
5.Built-in frequency converter adopts Schneider product, if any other brand components are required, please note when ordering.
6.Suitable for both steel pipe wiring and cable wiring.
