In the 220 kV large-scale hub power distribution scenarios, the lack of equipment intelligence and the high transmission loss under heavy loads are industry pain points. During procurement, the lack of intelligent equipment operation and maintenance, low compatibility with various types of supporting equipment, and long project implementation cycle are your concerns. We have launched the 75000 kVA/220 kV large-scale high-voltage transformer, which focuses on intelligent efficiency and super-large capacity carrying. Customizable high-end Oil Immersed Transformer specifications can be provided, compatible with the standard of Dry Type Transformer, and intelligently linked with Box Type Substation, High And Low Voltage Switchgear. It is suitable for the grid connection of Combined Photovoltaic Substations of tens of thousands of kilowatts and the national-level 220 kV backbone power grid hub power supply. When paired with an Electric Power Converter, it can achieve intelligent power regulation and low-loss transmission, effectively solving the problems of insufficient intelligence, high loss, and poor compatibility in the power supply of large hubs. It enables the backbone grid to operate intelligently, efficiently, and safely, helping purchasers shorten the project implementation cycle, reduce comprehensive operating costs, and create a high-end intelligent power hub. Its core value lies in intelligent operation and maintenance and super-large capacity adaptation. Its application covers the national-level 220 kV backbone grid, tens of thousands of kilowatt-level new energy bases, and large industrial clusters hubs. It is the core benchmark equipment for the 220 kV-level large-scale intelligent power distribution scenarios.

Product features :

Equipped with an intelligent operation and maintenance system, it can monitor and remotely control the operating status in real time, automatically issue warnings for abnormal hazards. The power transmission loss is reduced by more than 20% compared to products of the same specification. Combined with the Electric Power Converter, it can achieve precise power regulation, and is compatible with Combined Photovoltaic Substations for large-scale grid connection, significantly enhancing the intelligence level of power supply.

2. Fully compatible and easy to install: Based on the requirements of national power grids and large-scale new energy bases, the core parameters of Oil Immersed Transformer can be customized to perfectly match the equipment of Dry Type Transformer. There is no need for extensive modification of the existing Box Type Substation and High and Low Voltage Switchgear systems. The installation and commissioning process is efficient, significantly shortening the project implementation cycle and reducing the adaptation cost.

Tips :

The installation must strictly follow the 220 kV super-large intelligent power equipment installation specifications. Special attention should be paid to ensuring the foundation’s load-bearing capacity, intelligent heat dissipation, and lightning protection grounding. After customizing the Oil Immersed Transformer, the insulation oil quality, oil level, and sealing performance should be tested every six months. When interacting with the Box Type Substation and Electric Power Converter in an intelligent manner, the intelligent monitoring system needs to be calibrated regularly to ensure smooth interaction.
