For the re-equipment of one of the mining and metallurgical plants, the specialists of "Electro Solutions", representing the EKF brand in Russia, selected modern analogues of devices that have served their term.
The project used a PRO-Drive 500 frequency converter, which allows for long cable routes. In its basic configuration, the device supports the Modbus TCP protocol. The AC drive can control motors with a power range from 1.5 to 630 kW at a voltage of 400 V. The modular design allows you to assemble drive systems with a common power supply unit (AC-DC converter) and several inverters (DC-AC converters) connected on the same DC bus.
Updated GV2P (0.1–32 A) motor starter circuit breakers with a thermomagnetic trip were also installed. They are designed for switching AC circuits with a voltage of up to 690 V and a frequency of 50/60 Hz, control and protect three-phase asynchronous motors from overload, phase loss and short circuit. For the same purposes, updated APD-32 and APD-80 motor starter circuit breakers have been added to the solution.
KTE contactors and small-sized KME contactors, when a command is given, close the circuit and supply power to the motor, providing start-up and shutdown without prior stopping in the network. AV Power molded case circuit breakers protect power circuits and motors from overloads and short circuits.
