S9.S11 transformer and transformer tank, - for S9.S11M series transformer, S11-M series of transformers, the new S9 series three-phase oil-immersed transformers Shenyang Transformer Research Institute introduced new technology, no-load low load loss, anti-lightning impulse,short circuit capability, energy-saving effect is obvious, significant social and economic benefits, is the country ideal for both network reconstruction.S11-M Series fully sealed oil-immersed distribution transformers, with all oil-filled sealed type, no storage cabinet, transformer load due to changes in temperature and changes in oil volume, complete flexibility in the tank by the transformer to the mediation, the load loss30% lower than the S9, anti-lightning impulse short circuit capability, significantly more energy savings and reduce the appearance size of the transformer, is currently the new energy-saving products.STRUCTURE 1. Box change the basic structure is pided into "eye" shape and "goods" shape."Eye" shaped structure of high-pressure chamber wide, able to ring or dual power supply connection schemes; "goods" shaped structure, a wide low-pressure chamber can be placed 5 to 6 sets of low-voltage cabinet, 6 to 12 back to cable outlet.According to user requirements, box-type variable can be set to operate within the corridor.2. Cabinet frames are made of channel steel and angle steel welded together with high mechanical strength.Tank shell material is 2mm thick aluminum alloy plate, with excellent corrosion resistance, by painting colored in harmony with the surrounding environment.3. Have good ventilation and insulation measures.Box with up and down around the ventilation duct, air duct also Jianzuo ribs, items covered in the sandwich box with 30 ~ 50mm thick in a new flame retardant insulation material layer can effectively prevent the sunradiation.In the transformer room is equipped with automatic control of the axial fan at the bottom of the door of the upper set "A" shaped ventilation window, which ensures a fully loaded transformer in the hot season run.4. Box outside the door, with rain and blockades, anti-rust, anti-theft locks dedicated, open the outer door can be positioned after the opening position.5. Outside the door frame to install a dedicated rubber moldings, box top with the rain around the eaves, the bottom of the cable into the outlet to install a tower-shaped rubber bands, can effectively prevent rain, dust prevention, anti-small animals,ensure reliable operation of electrical equipment.6. Transformer room can be set to track and transformer car, transformer easy to install, replace.7. Box-type variable high-pressure part of the selection pressure vacuum switch or load switch ring counter, easy to operate and reliable.8. Transformer room is located two doors, open style of the door within the network, by galvanized metal mesh, mesh diameter = 8mm, to ensure the safety of inspection personnel.9. High pressure into the line of the program is pided into cable, overhead line into two, low-voltage cable outlet outlet generally.10. Box under the lifting by way of lifting a smooth and reliable.11. Simple Box variable transformer part of the exposed, high and low pressure terminal closed, low-voltage part can be set according to user needs to return to qualify 2-4.35kV class SZ9 Series Double Winding OLTC compared with SZ8 products, performance is more advanced, energy saving and better, so it is widely used in railway and rural power grid construction and transformation.
