S11-M-30-2000/10 sealed oil-immersed transformer serves power system of AC 50Hz, rated voltage up to 10kV. It is suitable for petroleum, metallurgy, chemicals, textiles, light industry enterprises and dusty locations. |
| 3.1 iron core The core is cold rolled silicon steel sheet with high magnetic conductivity3.1 iron coreand grain orientation . The core is a core type core and a fully inclined seamstacked core . Its core column is a circular section with multistage steps , andthe yoke and iron core are of equal cross-section. |
| 3.2 windings The winding adopts corrugated oil duct , no paint dipping process and tightband binding ; the winding is concentric coil ; the high-voltage winding hastap corresponding to tap voltage requirements , which is led to the tapchanger . The switch is installed on the box cover , and the tap voltage canbe changed after the power supply is cut off . |
3.3 safety protection device |
3.4 oil temperature measuring device |
3.5 transformer tank The oil tank of transformer is composed of corrugated wall , the surface is sprayedwith dust and the paint flm is frm . The corrugated heat sink not only has coolingfunction , but also has " breathing function . The elasticity of corrugated heat sink cancompensate for the change of transformer oil volume caused by temperature riseand fall . Therefore , the fully sealed transformer has no oil conservator and reducesthe overall height of transformer. |
| The vacuum oil injection process is adopted in the packaging of the transformerto completely remove the gas in the transformer , and the transformer oil doesnot contact with the air . It can effectively prevent oxygen and moisture frominvading the transformer , which may lead to the degradation of transformerinsulation performance and the aging of transformer oil. |
