200 kVA 20 kV Oil-immersed Power Transformer

During the stage of 10 kV upgrade and 20 kV high-voltage network integration, many industrial areas faced problems such as single selection of high-voltage equipment and unreasonable load distribution in the intervals. Most conventional equipment was difficult to meet the long-term operation standards of 20 kV voltage level. The 200 kVA 20 kV oil-immersed power transformer specifically addresses this shortcoming, and can be combined with Box Type Substation for complete layout, and interact with High And Low Voltage Switchgear to balance regional power load, providing a reliable high-voltage power supply solution for industrial and mining areas and centralized distribution stations in towns.

This equipment is mainly used in 20 kV voltage level scenarios such as expansion of industrial and mining enterprises, expansion and renovation of town power grids, and expansion and renovation of industrial parks. It can independently undertake basic power supply in the area, and can also be mixed and networked with Oil Immersed Transformer and Dry Type Transformer. It relies on Electric Power Converter to regulate power quality and connect to Combined Photovoltaic Substations to complete distributed energy grid connection, adapting to the transition renovation of old and new power distribution systems. The overall adaptability is wider, effectively reducing the investment cost of power grid renovation.

Product Features
1.The high-pressure configuration has strong adaptability. It optimizes the insulation configuration based on the 20 kV high-voltage operation standard, has solid withstand voltage performance, balanced load output, and is suitable for medium- and long-term stable operation.
2. The overall structure is compact and regular. The sealing process is solid, and the environmental adaptability is strong. It can maintain stable operation in both indoor machine rooms and outdoor distribution points.

Tips for Use
During the layout stage, make sure to plan the site well to ensure good air circulation, reduce the risk of a sealed and stuffy environment, and delay equipment aging.
Regularly inspect the sealing status of the outer shell based on local climate conditions to promptly avoid potential hazards caused by the long-term accumulation of dust and moisture.

Frequently Asked Questions
Q1: How compatible is the 20 kV high-voltage version in grid renovation projects?
A1: It fully complies with the current grid upgrade standards. The interface specifications are universal, and it can directly integrate into 20 kV high-voltage renovation lines without the need for extensive changes to the original distribution layout. This makes the renovation implementation more efficient.

Q2: Will long-term light load or significant load fluctuations affect the equipment lifespan?
A2: The electromagnetic structure of the body has been optimized, which can withstand load fluctuations. The power loss during light-load operation is controllable, and it can maintain stable operation even under frequent load fluctuations, without accelerating internal wear.

Q3: Compared to dry-type equipment, what are the actual advantages of the oil-immersed structure under the same operating conditions?
A3: The cooling system is more mature, there is sufficient load redundancy, the endurance capacity under extreme conditions is stronger, the overall purchase and later maintenance costs are lower, and it is more suitable for large-scale outdoor and industrial regular power supply scenarios.
