Why mining equipment is especially suitable for soft starters


What are the machines that are often used with mining equipment? A large number of cranes, conveyors, ventilators and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment. In addition, there are crushing equipment, grinding equipment, sand making equipment, mineral processing equipment, etc., which are used in coal mines, including flotation machines, classifiers, magnetic separators, vibrating screens, dryers, coal grinding machines, and coal washing machines. , High-power fans, pumps, centrifuges, screw feeders, scraper conveyors, air compressors, condensers and elevators, etc. These devices have the characteristics of simple structure, reliable operation, easy maintenance and economical operation cost.




These devices start to generate instantaneous high-voltage current, which will directly impact the power grid, cause power grid fluctuations, and affect the stability of the power grid and other equipment in the same power grid. When starting directly, the instantaneous high current will also cause great damage to the motor and reduce its service life. , In case of downtime, it will cause great losses.




Ekwell soft starters, which are often used in mining equipment, have complete motor protection functions, including power distribution, gas, insulation, overload, overcurrent limiting, undervoltage, short circuit, phase loss, three-phase current imbalance and overheating protection and other functions.


Soft starters also have several advantages:


1. Compact structure and quick installation.


Compared with the inverter of the same power, the volume of the soft starter is only about one-half of that of the inverter. It is located in a remote mine and is much more convenient to transport.


2. Long service life


With thyristor as the main circuit component, it can run continuously for several years without downtime for maintenance. It also effectively prolongs the life of the equipment.




3, easy maintenance


The soft starter has a simple structure, which is convenient for daily inspection and maintenance.
