5000 kVA Pad Mount Three-Phase Oil-Immersed Distribution Transformer 35kv
WINLEY presents a comprehensive range of liquid-filled Three-Phase Pad-Mounted distribution transformers that adhere to relevant ANSI®/IEEE® standards. Capable of handling high voltages reaching up to 34.5 kV and ratings up to 5,000 kVA, these transformers are ideal for applications demanding high voltage and substantial capacity, including power substations and industrial power consumption.
STRUCTURE
1)The transformer part and the control cabinet part of the United States variation, of which the transformer part is a fully sealed structure, and the insulating oil can be two types of high ignition point oil or ordinary oil.
2)The control cabinet is divided into a high-voltage room and a low-voltage room.
3)The high-voltage room is equipped with: high-voltage cable plug, lightning arrester, load switch operating handle, non-excitation tap switch handle, plug-in fuse, pressure release valve, thermometer, pressure gauge, oil Position gauges, oil filling plugs, oil drain valves, etc., load switches, off-excitation tap changers, plug-in fuses, etc. are all immersed in transformer oil together with the transformer core. The high-voltage cable and the transformer are connected by elbow cable connectors.
4)The low-voltage side can be installed with air circuit breakers, current transformers, as well as electric energy meters, ammeters and voltmeters, and output circuits and capacitance compensation devices can be configured according to user needs.
Performance
1.using the corrugated tank sealing structure, enclosure, to prevent contact with air, water in contact with the transformer, reducing the degree of aging of the oil, to extend the service life of the transformer; Through the elastic deformation of corrugated to adjust the volume change of transformer oil heat bilges cold shrink.
2. the product structure for the outdoor type, oil-free pillow,anti-fouling high level;; in normal use period without replacement transformer oil, truly maintenance-free, to ensure safe operation and reliability of the grid.
3. the transformer has a pressure release safety devices, when a transformer failure pressure is too high, it can be safely released reliably through the pressure relief valve to prevent the expansion of the accident.
