  • 3 product widely used in mining application

 

 

 

 

 

 

 

The unit as a whole is imported, however an HICONICS- made inverter can be used on request.

 

Key Features

• Uses advanced heat emission technology, which solves technical problems often encountered with large power flameproof VFDs 

• Equipped with a vector control AFE phase switch which incorporates closed loop control technology allowing for a small starting current, stable starting speed and less rush to grid

• Motor Protections: zero-sequence current protection as well as short circuit, over load, over current, over voltage, under voltage loss control and over temperature protection

• Perfect mute control reduces motor heat and high frequency noise

• On line control, speed set, line shape and S shape acceleration/deceleration set

• RS-232 standard communication connection, possible linkage application extension

• Uses a water-cooling method that, in comparison with a forced air method, is more efficient and requires a smaller volume, reduces noise and is suitable for subterranean use.

 

ZJT product series has obtained national patents that will allow for improvements of flameproof technology.

  This product makes use of a high performing imported inverter that performs more efficiently than a DC variable speed system. It is also markedly simpler in structure allowing for increased reliability and easy maintenance. The ZJT product series has been used in an applied mining environment containing methane and coal dust to soft start /stop and adjust the drive with heavy load. With a small starting current, stable starting speed, and adjustable starting time, it is able to use less crush to grid and generate a larger torque output. While the VFD is running the running frequency can be adjusted according to the motor running frequency to achieve the speed and torque required. The starting mode can divided into steps or started directly. Added protections like a normal magnetic starter and emergency stop are also included. All of these functions guarantee secure running and energy savings.
