The intelligent system ensures that the power supply is foolproof
While ensuring the "full power" of snowmaking, the reliable use of temporary loads such as venue security inspection, timing and scoring, and technical equipment room is also an important part of power supply guarantee.
As one of the venues with the largest number of temporary power facilities, Shougang Ski Jumping Platform is affected by multiple factors such as power supply assurance, epidemic prevention and control, weather changes, etc., and has the characteristics of many guarantee points, high standards and closed environment. In order to ensure the use of electricity during the game, in April this year, the State Grid Beijing Shijingshan Power Supply Company actively docked the electricity demand of various fields of the venue in accordance with the unified arrangement of the State Grid Beijing Electric Power, strictly controlled the time node, and met the electricity demand of the venue in advance.
Up to now, the venue has built a pre-installed power distribution room, installed 3 combined diesel generators, 16 low-voltage ATS boxes, 38 OBS technology distribution boxes, 37 uninterruptible power supplies, and laid 900 meters of high-voltage cables and 52,750 meters of low-voltage cables.
At the same time, the Shougang Ski Jump Power Support Team also carried out hidden danger investigation, equipment testing, and terminal load power traceability for the permanent facilities and power facilities of the venue. Strengthen the control of the power guarantee process of the venue to ensure that the power supply guarantee during the Shougang Ski Jump is foolproof.
