Are you looking for energy saving in application like Mono cable rope way on IM motor? AMTECH offers highly reliable Axpert system

Limitation of previous system:

In the previous arrangement, the motors were operated through VFD and were stopped through dynamic braking system which resulted in heavy energy loss.

It was not possible to operate the rope way above 31 Hz, speed was a limiting factor.

Drive used to trip frequently due to high amount of regeneration.

More Bucket loading time resulting in less rope way output.

Challenges:

Economical operation by reducing power consumption of rope way.
Rope way output is very less compared to capacity.
Frequent tripping of the drive due to very heavy regeneration.
Unable to operate rope way above 31 Hz.

Solutions:

AMTECH has supplied and commissioned 4Q drive to get over the problem of frequent tripping and prevent the wastage of regenerative energy.
Use of 4Q drive has resulted in increase of rope way output by 50 %.
System runs smoothly as regenerative energy is diverted to another load.
It is possible to operate rope way at 46 Hz, considerably higher then the previous case.

Benefits:

Rope way output increased to 135 bucket / Hour (74 Ton / Hour) from 90 bucket / Hour (49 Ton / Hour)
There is energy saving of more than 20 kW.
Adequate motor protection.
Smooth operation results in increased life of mechanical and electrical parts.

AMTECH POWER PRODUCT OVERVIEW - DECS 150 WITH MOTORIZED VARIAC

Redundant AVR system refers to the backup system, i.e., two AVRs used (master/slave

combination). Two types of redundant systems exist: 1) Cold redundant and 2) Hot redundant

-Cold redundancy is for non-critical processes where time is not a high priority and human intervention is acceptable. In this system if there is any failure occur then manually we have replace that faulty part and start again.

-Hot redundancy offers instant process correction when a failure is detected. In this system there will be one standby system which will always follow the main controller so, in case any failure happen then standby system will take over.

Using a motorized variac to control the DECS-150 output is an example of cold redundancy, as human intervention is possible here.

Motor driven variacs are operated to maintain output voltage regulation as shown in figure. This scheme can handle heavy surge currents frequently used in industrial setting due to high surge capability.

The above figure shows the single phase motorized variac to be used for the DECS-150. The DECS-150 output is to be controlled.
