23 complete switchgear units for Metinvest KRMZ as part of the overhaul of high-voltage equipment (over 1000 V), specifically the replacement of equipment in the 6 kV distribution unit.
Сomplete switchgear units is designed for receiving, accounting, protection, and distribution of electrical energy in enclosed distribution devices with a voltage of 7.2–40.5 kV AC, frequency of 50 Hz.
MAIN PARAMETERS:
- Nominal voltage of the main circuit, kV - 6
- Nominal frequency of the main circuit, Hz - 50
- Nominal current of the main circuit, A - 4000
- Nominal current of the electrodynamic stability of the main circuits, kA - 63
- Dimensions (excluding protruding elements):
- Height, mm - 2350
- Width, mm - 750
- Depth for lines, mm - 1550
- Depth for inputs, mm - 1850
ADVANTAGES OF OUR SOLUTION:
- Personnel protection system implemented with electrical and mechanical interlocks during work, rigid partitions between compartments.
- Two-sided servicing provides accessibility of all nodes for maintenance.
- Only control elements, switches, and mode indicators are located on the facade part of the housing. Elements used during service operations are hidden inside the housing.
- Microprocessor devices are used in the relay protection and automation systems, which, when configured, are programmed to perform specific functions depending on the purpose of the cell.
This is a significant event as it marks the first direct delivery of this equipment to one of the Metinvest group's assets, indicating a crucial step in improving and modernizing the group's electrical infrastructure.
Such equipment plays a key role in ensuring the stable and efficient operation of the power grid, essential for the stability and safety of energy supply.
