Compliance of the HT cabin - Maison de la Culture

Replacement of equipment and security of high voltage cabins – Maison de la Culture. The Maison de la Culture is powered by two high-voltage cabins. The main cabin, located under the staff premises, includes a high voltage feeder supplying a second cabin located near the Semois, called the “parking cabin”. Existing installations are equipped with exposed high-voltage equipment, including copper bars providing connections between the different cells: arrival, protection and transformer. The parking booth is kept in service to allow the subsequent installation of charging stations for electric vehicles. Given the current configuration of the installations, they no longer meet the required security requirements. It is therefore necessary to replace the existing equipment with fully enclosed high voltage cells, preventing any access to live elements. Work to be carried out: The work will include the dismantling of the existing fences as well as the removal of the high voltage equipment in place, with a view to replacing it with fully closed and secure cells. However, part of the fences will be retained in order to maintain the insulation of the transformer. Additional plexiglass protection will also be installed to prevent the risk of contact with elements presenting an electrical hazard. Following the visual inspection carried out jointly with ORES, it was estimated that the existing transformer could be retained. This conservation nevertheless remains conditional on verification of the quality of its insulating oil. It is also planned to equip the transformer with a monitoring relay to monitor its operation. Furthermore, the door separating the entrance to the cold station, at the level of the parking cabin, will be reinforced in order to improve the security of the installation.
