200 kVA 20 kV High-Efficiency Oil-immersed Transformer: Energy-Saving and Stable Power Distribution Equipment
Currently, high-voltage power distribution equipment commonly suffers from industry pain points such as high no-load losses and poor operational stability. Many purchasers frequently face challenges related to excessive energy consumption and high failure rates under harsh operating conditions. To address these issues, this 200 kVA 20 kV Oil Immersed Transformer employs an optimized electromagnetic structure and a fully sealed heat dissipation design, focusing on two core advantages: high efficiency and energy saving, and stable operation and maintenance. It is suitable for various high-voltage power distribution scenarios. In practical applications, the equipment can effectively reduce long-term energy costs, is suitable for complex environments such as outdoor and industrial settings, has a low failure rate, and a long service life. It can be flexibly combined with Dry Type Transformers, Box Type Substations, and other equipment to complete the entire power distribution system. It is widely used in industrial plants, photovoltaic power stations, and urban and rural power grid upgrades. It can also be integrated with High And Low Voltage Switchgear, Electric Power Converters, and Combined Photovoltaic Substations to achieve integrated power supply solutions.
คุณสมบัติผลิตภัณฑ์หลัก
1. High Efficiency and Low Consumption: Superior performance through precise electromagnetic parameter optimization significantly reduces no-load and load losses, exceeding industry standards in Energy Efficiency. Long-term operation can significantly reduce enterprise power consumption and meet the needs of continuous and stable power distribution operations.
เคล็ดลับการบํารุงรักษาเชิงปฏิบัติ
1. Routine maintenance only requires periodic checks of insulating oil level, oil quality, and equipment sealing condition; frequent disassembly and maintenance are unnecessary. During rainy seasons and high-temperature conditions, the frequency of inspections can be increased appropriately to prevent dust and moisture intrusion from affecting equipment performance.
