In the figure: 1 switch board, 2 horizontal exhaust airway, 3 vertical exhaust airway, 4 outer exhaust fan, 5 clean air supply fan, 6 automatically controlled cabinets, 7 temperature and humidity detector, 8 transmission cabinets, 9 temperature probe, 10 air conditioners, 11 fans, 12 wireless smoke detector probes, 13 smoke alarm controller, 14 alarm lamp on duty room, 15 cables.
Detailed Description
The attached drawing is a concrete embodiment of the utility model.
The utility model discloses a rolling mill electricity distribution room cooling economizer, in the electricity distribution room, install vertical exhaust airway 3 on each switch board 1, be connected the air outlet on exhaust airway top and switch board casing upper portion, there is the air intake switch board casing lower part, and vertical exhaust airway collects and is connected to horizontal exhaust airway 2, horizontal exhaust airway end-to-end connection fan 4 of airing exhaust outward.
Install special clean air supply fan 5 outside the electricity distribution room (prevent that the air because of sending to the electricity distribution room contains dust and gets into the switch board more, leads to short-circuit fault to take place) and supply air for the electricity distribution room by force, clean air supply fan and automatically controlled cabinet 6 are connected, are controlled by the electric control cabinet.
An electric control cabinet 6 is installed in the power distribution room, a temperature and humidity detector 7 is installed outside the power distribution room and connected with the indoor electric control cabinet, a temperature measuring probe 9 (PT 100) is installed on 4 high-power transmission cabinets 8, and the temperature measuring probe is connected with the electric control cabinet.
Each air conditioner 10 and each fan 11 (including an outer exhaust fan and an indoor circulating fan) in the distribution room are connected with the electric control cabinet, and are controlled by the electric control cabinet to act when the temperature and the humidity reach set values.
A wireless smoke detector 12 is installed every 4 meters in cable pit one side in the distribution room and above the distribution room, and each smoke detector signal connection distribution room inner wall installation's smoke alarm controller 13, and the smoke alarm controller is connected automatically controlled cabinet and the room alarm lamp 14 of on duty, and the smoke alarm controller obtains the signal feedback to the automatically controlled cabinet in the distribution room, and automatically controlled cabinet action, fan, air conditioner stop, and smoke alarm controller output alarm signal simultaneously, installs the alarm lamp work at the room of on duty.
