In the 220 kV large-scale power distribution scenarios, the equipment’s carrying capacity is insufficient and the coordination of the power grid is poor, which are the industry’s pain points. During the procurement process, concerns about the high difficulty of customizing the equipment, the poor compatibility with the supporting system, and the high risks of later operation and maintenance are your troubles. We have launched the 63000 kVA/220 kV large-scale high-voltage transformer, specifically designed for 220 kV backbone power grid hubs and super-large energy bases. It can be customized with high-end Oil Immersed Transformer specifications, compatible with Dry Type Transformer supporting standards, and deeply coordinated 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 main power supply of regional backbone grids. When paired with an Electric Power Converter, it can achieve lossless transmission and precise regulation of electrical energy, effectively solving the problems of unstable power supply for large-scale loads, high adaptability difficulty, and high operation and maintenance risks. It enables the backbone grid to operate efficiently, safely, and for a long time, helping the purchaser build a stable and reliable large-scale power transmission hub and highlighting the benchmark value of the core power supply equipment. Its core value lies in the coordination and adaptation of large-scale load carrying and the power grid. Its applications cover regional 220 kV backbone grids, super-large new energy bases, and large-scale industrial core areas. It is the core supporting equipment for 220 kV-level large-scale power distribution scenarios.

2. Customized adaptation, controllable operation and maintenance: Based on the actual demands of the backbone power grid and super-large new energy bases, the core parameters of Oil Immersed Transformer can be customized to perfectly integrate with Dry Type Transformer supporting equipment. No large-scale renovation of the existing power distribution system is required. The equipment is equipped with an intelligent operation and maintenance monitoring system, which can promptly alert of any operational abnormalities, significantly reducing the difficulty and risks of later operation and maintenance.

Tips :

The installation must strictly follow the installation specifications for 220 kV super-large power equipment. Special attention should be paid to ensuring the bearing capacity of the foundation, 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 operating in conjunction with Box Type Substation and Electric Power Converter, regular coordinated grid debugging should be carried out to avoid sudden changes in grid load that may affect the safe operation of the equipment.

FAQ (Frequently Asked Questions):

Q1: Can this transformer be compatible with megawatt-scale Combined Photovoltaic Substations? How long will the customization process take?

A1: Fully compatible with multi-gigawatt Combined Photovoltaic Substations, it can efficiently undertake the task of ultra-large-scale power transmission and grid connection. When combined with the Electric Power Converter, it can enhance the efficiency and stability of grid connection. The regular customization cycle of the Oil Immersed Transformer is 30-35 days. It can be flexibly adjusted according to the project progress. It is compatible with Box Type Substation and High And Low Voltage Switchgear without any additional time consumption.

Q2: Is the operation and maintenance of extremely large high-voltage equipment very difficult and does it require a significant investment of human resources?

A2: The operation and maintenance process is controllable. The equipment is equipped with an intelligent monitoring system, which can monitor the operating status in real time and alert for potential abnormalities. Routine maintenance only requires quarterly calibration of the monitoring system and inspection of insulation performance. For Oil Immersed Transformers, the insulation oil needs to be replaced once a year. No significant investment in manpower is required. Ordinary maintenance personnel can operate independently after professional training, significantly reducing the maintenance labor cost.

Q3: Can the product’s after-sales support meet the requirements of large-scale projects, and how efficient is the fault resolution process?

A3: We have an exclusive large-scale high-pressure equipment after-sales system, offering 3-year free warranty. During the warranty period, non-human faults are free for repair and replacement of core high-pressure components. A dedicated after-sales team is equipped, responding 24/7. In remote areas, on-site handling is provided within 48 hours. Lifetime customized technical guidance is provided, fully meeting the long-term operation requirements of large-scale projects.
