1 Overview
transformer Chamber steel doors and windows It is a steel door with ventilation and heat dissipation function specially used in the transformer room window 。
2. Scope of application:
It is applicable to the doors and windows outside the transformer vessel that are independent or attached, closed or open in industrial and civil buildings. Enclosed transformer room is divided into high type and low type.
3. Door opening size:
The door opening width of transformer room is 2100, 2400 and 3000 mm; There are three kinds of door opening heights: 2700, 3300 and 3600mm. The door leaf height of the open transformer room is 1800mm.
4. The window type of the steel window in the transformer room is divided into the air inlet window at the lower part of the high type transformer room and the air exhaust window at the upper part of the closed type transformer room. Exhaust window is divided into louver and Cable There are two kinds of louvers for installing holes
5. Professional manufacturer - Anhui Secdoor Factory, window type code:
YC1- steel plate Mesh window, used for the air inlet window at the lower part of the high type transformer room; YC2 - shutter with steel mesh, used for the upper part of closed transformer room; YC3 - Louver with cable installation hole and steel mesh, used for the upper part of enclosed transformer room.
6. Window opening size:
The opening width of the window is 2100, 2400 and 3000 mm. YC1 window has two heights of 600 mm and 900 mm; YC2 window has six heights of 600, 900, 1200, 1500, 1800 and 2100mm; YC3 window has five heights of 900, 1200, 1500, 1800 and 21 00mm.
7. Selection instructions
7.1 The transformer room should adopt natural ventilation.
7.2 According to the requirements of the national standard Code for Design of 20kV and Below Substations (GB 50053-2013), in places with basements, combustible storage yards, combustible dust or fiber, the door from the transformer room to the outdoor shall be fireproof.
7.3 The steel doors and windows of the transformer room are selected according to the capacity of the transformer, the propulsion mode and the effective area of the air inlet and outlet provided by the electrical specialty according to the local climate conditions. The effective air inlet area of various air inlets is listed in the selection drawing (the calculation method of the ventilation area of the louver with steel mesh is: the effective area of the louver times the effective coefficient of the steel mesh 0.77). Therefore, the air inlet on the steel door of the high type transformer room provides two heights of 500 and 800 mm; The air inlet louver under the door is also provided with two heights of 600 and 900 mm
7.4 In order to directly find the effective air inlet area of each air inlet and the overall air inlet area of the transformer room, this atlas (17j610-1) combines the door type YM1, YM2, YM3 with the shutter YC1 under the door, and places them in the selection drawing.
7.5 In order to meet the needs of areas with heavy wind and rain, the atlas of Anhui Secomen Factory, a professional manufacturer, provides a steel door for the transformer room that is rain proof. Sealing strips are set around the door frame, and the doors and windows with louvers use anti rain louvers (not reflected in the door type code, and text description shall be added when selecting)
7.6 If it is necessary to set a rat guard ram inside the steel door of the transformer room, it should be explained in the engineering design. This atlas provides the construction method, but no rat guard ram number is set in the selection drawing. See page Y28 for the method.
