Overview
S11 electric transformer oil is mainly used for breaking and closing the load current,overloadcurrent and short circuit current in the electronic system.The utility model is suitable for protectingand controlling the powe distribution system of thesubstation and the t mine enterprise,and the place where the rural power network operates frequently.it can also be used as the sectionalized switch of the power network,after the control is installed,the distribution network automation can be realized.
Features
1. The transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces no-load loss and no-load current, and binds the core to ensure the tightness of the core and reduce noise.
2. The high and low voltage windings are made of oxygen-free copper. The low voltage windings of 500KVA and below adopt a double-layer cylindrical structure, and the high-voltage windings adopt a multi-layer cylindrical structure.
3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the power supply quality.
4. The transformer is a fully sealed structure, prolonging the service life, free of hanging cores and maintenance-free.
5. The measured noise value is lower than the standard.
After this series of Satons transformers are normally transported, they can be installed with relevant parts and components, and can be put into operation after passing the inspection.
