BBP58 series explosion-proof motor speed control frequency converter system (Ⅱ B) model meaning


Example of appearance


BBP motor speed control frequency converter can jump the speed of ordinary three-phase asynchronous motors by changing its output frequency conversion, in order to meet the requirements of production processes or achieve energy-saving purposes. The energy-saving rate can be
Reaching 30% to 60%, it can be used as a soft start controller for electric motors, and can also form a closed-loop speed control system through control circuits such as sensors and transmitters. Easy installation and operation, smooth start-up without impact electricity
Flow (soft start), greatly reduced power capacity, constant power factor (cos π≈ 1), and various protection functions for fault display.
Install 11 copper pipes inside the explosion-proof enclosure Enhance automatic ventilation, cooling and heat dissipation Enable the frequency converter inside the explosion-proof chamber to operate at normal temperature.
Due to the fact that the core component of the variable speed drive is a single-chip microcomputer, it has strong functions:
Overcurrent protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power outage protection, and phase failure protection.
After the phase number is displayed, it indicates frequency, speed, load rate, or current, etc.
The frequency can be manually adjusted. The process curve of variable speed over time. The frequency can also be controlled by signals provided by the DCS system.
This product uses Japanese Fuji or SA-NKEN kits for speed control frequency converters. The cabinet is also equipped with an ammeter, voltmeter, automatic air switch, indicator light, AC contactor, and power frequency converter switch
And start, stop buttons, etc. We can design principles based on the process requirements of different users and select appropriate operating methods for device configuration.
Copper pipe or cable wiring, cable wiring must be equipped with cable clamping and sealing joints.
