2、Explosive-proof and intrinsic safety type frequency converter for mines

uproduct description

The ground general-purpose low-voltage frequency converter produced by our company is specially designed for permanent magnet motors. It has good matching with permanent magnet synchronous frequency conversion motors. It adopts vector control to achieve precise torque control. At the same time, the frequency converter has high efficiency and electromagnetic The characteristics of superior compatibility and strong environmental adaptability can effectively reduce the interference to the power grid and surrounding equipment.

uScope of application

It is widely used in belt conveyors, hoists, mills, fans, water pumps and other occasions. This type of frequency converter is also suitable for all kinds of asynchronous motors.

uMain technical features:

1) Two-level output, independent development, cabinet installation, can be customized according to users.

2) It adopts vector control without speed sensor, with large starting torque and stable torque output.

3) The control software is specially designed for permanent magnet synchronous machines. Through techniques such as rotor positioning detection and torque angle matching, it effectively solves the common "startup difficulties" and "startup difficulties" of permanent magnet synchronous machines without a position sensor. "Insufficient torque", "start reverse" and other issues.

4) The main circuit adopts non-inductive laminated busbar technology, original Infineon IGBT, and the control unit adopts modular design, which is convenient to install and maintain, and the spare parts are unified.

4) The standard configuration of input filter reactor, output filter, etc., EMC index meets the requirements of national standard, the output distance of the inverter is long, and the influence on the motor insulation is small.

) Based on the power balance of the star optical fiber network, when multiple machines are running, the master-slave and master-slave modes can be switched at will, and the power error of the multi-machines is less than 5%.

7) Cooling methods such as water cooling and air cooling can be selected.
