Under this year's investment program, distribution substation No. 55 was modernized in the coke shop
Kametstal is improving the reliability of power supply to coke oven battery No. 5. As part of this year’s investment program, the coke shop modernized distribution substation No. 55, according to a press release from the company.
The investment project involved the complete replacement of outdated contact equipment with modern automatic equipment made in Germany. New circuit breakers with current and thermal protection were also installed, as well as new electromagnetic starters instead of contactors. In total, four sections of the substation have been renovated, and the old equipment at RP-55 has already been decommissioned.
The new equipment with a high level of automation allows online monitoring of the circuit breakers. The sections are equipped with on-off visualization elements, which allows the electrician on duty to check the operation of each circuit breaker faster and more accurately.
“The three months of operation of the new equipment allowed us, first of all, to improve the reliability of the battery’s power supply and avoid downtime of the main equipment related to the reliability of power supply. Also, thanks to the metering system implemented as part of the modernization, which allows us to track electricity consumption online on a computer, we can now analyze the electricity consumption of each consumer throughout the day. This analysis allowed us to improve the accuracy of electricity consumption planning, and after accumulating analytical conclusions, we plan to develop energy-efficient measures to reduce electricity consumption,” said Olexander Shulzhenko, an electrician at Kametstal’s coke shop.
The modernization of electrical equipment has improved the working conditions of personnel, primarily due to less labor-intensive maintenance compared to the old equipment, and has also improved the safety of the electricians’ workspace.
As GMK Center reported earlier, in October 2024, Kametstal completed the overhaul of blast furnace No. 9. The repair contractors fulfilled the primary task of restoring the refractory lining of the furnace and the upper roof of the furnace and replacing four cooling plates.
