Description
The backbone power grid hubs at 220 kV level generally suffer from insufficient capacity reserves and high losses during long-distance power transmission. Most purchasers also encounter difficulties in selecting equipment due to low compatibility with existing systems and insufficient post-operation maintenance support. To address these issues, we have introduced the 120000 kVA/220 kV super-Large Power Transformer, which adopts a high-standard Oil Immersed Transformer design. It can be compatible with Dry Type Transformer for various operating environments and is integrated with Box Type Substation, High And Low Voltage Switchgear for unified operation. It also suits the grid connection of Combined Photovoltaic Substations and is compatible with Electric Power Converter to enhance the accuracy of power regulation. After deployment, this equipment can significantly enhance the carrying capacity of the regional power grid, reduce high-power transmission losses, ensure continuous and stable power supply, and mainly serve national-level 220 kV hub substations, billion-kilowatt-level new energy bases, and super-large industrial clusters. With ultra-high capacity and high reliability as its core value, it provides solid support for key power nodes.
Product Features
Ultra-large capacity stable output: The 120000 kVA rated capacity combined with 220 kV high-voltage conditions offers outstanding shock resistance and short-circuit protection capabilities, with low long-term full-load operation losses, and is suitable for large-power grid connection and hub power supply scenarios.
Comprehensive compatibility for all scenarios: It can be flexibly connected with various distribution systems, and does not require large-scale renovations to work in coordination with existing switch equipment, box-type substations, and new energy grid connection devices.
Tips
During the operation of the equipment, it is necessary to regularly monitor the oil level, oil quality and temperature rise of the Oil Immersed Transformer. When it is in coordination with the high-voltage cabinet and converter, avoid frequent overload to extend the overall service life.
FAQ
Q1: Can the equipment be directly connected to the existing 220 kV power grid and adapted for Combined Photovoltaic Substations?
A1: It can be directly connected. The parameters and interfaces are designed in accordance with grid standards. It can be seamlessly integrated with Box Type Substation and High And Low Voltage Switchgear, meeting the grid connection requirements for large-scale new energy power stations.
Q2: Is professional team required for daily maintenance, and is the maintenance cost high?
A2: No dedicated high-end technical team is needed. Routine inspections of insulation, oil conditions, and wiring are sufficient. Compared to the maintenance cost of the same level Dry Type Transformer, it is lower, and the process is simple and controllable.
Q3: How are quality assurance and after-sales response guaranteed?
A3: Long-term quality assurance services are provided. Core components are free for replacement in case of non-human faults. Rapid response for on-site visits is available nationwide. Special technical support is provided for hub projects to ensure continuous and reliable operation.
