S13 oil-immersed transformer is mainly composed of the following parts:
Iron core: Made of stacked silicon steel sheets, with high magnetic permeability.
Winding: Made of insulated copper wire or aluminum wire, divided into high-voltage winding and low-voltage winding.
Oil tank: Contains the internal components of the transformer and plays a heat dissipation role.
Oil pillow: Stores transformer oil and moves with the change of oil level.
Radiator: Dissipates heat through natural convection or forced convection.
Temperature controller: Monitors and controls the operating temperature.
Explosion-proof device: Prevents the transformer from exploding under abnormal conditions
Working principle of S13 oil-immersed power transformer
The working principle of S13 oil-immersed transformer is based on the principle of electromagnetic induction. When the high voltage power supply is connected to the high voltage winding, a changing magnetic field will be generated in the iron core, and this magnetic field will induce the voltage in the low voltage winding. By changing the turns ratio of the high voltage winding and the low voltage winding, the voltage can be increased or decreased.
Technical parameters and performance characteristics of 700kva oil-immersed power transformer
S13 oil-immersed power transformer has the following performance characteristics:
Oil-immersed structure: The low-voltage winding adopts a cylindrical or spiral structure, and the high-voltage winding adopts a multi-layer cylindrical structure, with small magnetic leakage, high mechanical strength, and strong short-circuit resistance
Fastening measures: The core and winding adopt fastening measures, and the fastening parts such as the height of the device and the low-voltage lead are equipped with self-locking anti-loosening nuts, which can withstand the vibration of transportation
Drying process: The coil and the core are vacuum dried, and the transformer oil adopts vacuum oil filtration and oil injection technology to minimize the moisture inside the transformer
Corrugated oil tank: The oil tank adopts corrugated sheets, which have a breathing function to compensate for the volume change of oil caused by temperature changes, reducing the height of the transformer
Application scenarios
The S13 transformer is widely used in industrial and mining enterprises, agriculture, civil construction, petroleum, chemical and other industries, especially suitable for box-type substations, oil fields, mines and other occasions
