SBT Series frequency conversion speed regulating device
1、 Overview
SBT type frequency conversion speed regulation device, applied AC electric machinery Frequency conversion speed regulation technology and soft start technology realize the stepless speed regulation and soft start of the motor, which is an ideal speed regulation device at present. This product is an imported high-performance silent type Frequency converter As the core, the speed regulation and starting of the motor can be realized without shortage. The control software with good performance, high cost performance and rich control software can meet the various needs of users, and can be widely used in building materials, petrochemical, power, metallurgy, paper making, textile, water supply and many other industries,
2、 Performance characteristics
1. Wide speed range, energy saving
According to the requirements of process and working conditions, the zero full speed, lossless and smooth adjustment is realized, and the equipment operates economically, saving more than 30% of electricity.
2. Motor frequency conversion soft start
The starting and stopping of the motor can realize smooth starting at rising speed and smooth stopping at decelerating speed, reduce the current impact during starting, reduce the mechanical impact and wear during starting and stopping, extend the life of the whole system, and the starting performance is better than reactor , Autocoupling transformer Isodepressurization starter 。
3. Manual standby control system can be designed
When the frequency conversion circuit fails, start the motor manually and operate at power frequency to ensure safe production;
4. The remote operation and display function can be designed;
The motor can be started and stopped on site, in the power distribution room and in the central control room, and the working condition of the motor can be observed
5. The function of emergency signal for protection startup is perfect;
It has complete protection and startup emergency signal functions such as overcurrent, overload, overheating, overvoltage, undervoltage, phase loss, short circuit, etc. to ensure the safety and reliability of the system
