80KVA 10KV Oil-immersed Transformer with No Excitation Voltage Regulation: Dedicated Equipment for Stable Power Distribution

 

In current low- and medium-voltage power distribution scenarios, conventional power equipment generally suffers from high losses, poor voltage adaptability, and insufficient outdoor operational stability. Many industrial and mining projects and park power distribution projects often face the practical problems of cumbersome equipment maintenance and voltage fluctuations affecting Electrical Equipment. To address these issues, this 80KVA 10KV Oil Immersed Transformer adopts a no-excitation voltage regulation structure design, relying on mature oil-immersed heat dissipation and insulation technology, making it suitable for various small and medium-sized power supply scenarios. This equipment can accurately match the needs of conventional power grid substations, effectively reducing operating energy consumption and failure probability. It exhibits excellent long-term operational stability and can be flexibly combined with Dry Type Transformers, Box Type Substations, High And Low Voltage Switchgear, etc., and is widely used in urban and rural power grid transformation, industrial plants, photovoltaic projects, and other scenarios. It can also be used with Electric Power Converters and Combined Photovoltaic Substations to complete the construction of a complete power system, comprehensively ensuring the stable operation of the power distribution system.

 

This transformer is a 10kV three-phase off-grid voltage regulating distribution device, primarily suitable for small and medium-sized industrial and commercial, residential, and small photovoltaic power station distribution scenarios. The equipment abandons complex load voltage regulation structures, adopting a power-off voltage regulation mode, resulting in a simplified structure and low failure rate, perfectly meeting the low-cost, high-stability procurement needs of small and medium-sized power distribution projects. Compared to similar transformers, it has stronger adaptability, seamlessly integrating into high and low voltage complete power distribution systems and cooperating with various power equipment, balancing practicality and economy, making it the preferred transformer for small and medium-capacity power distribution scenarios.

 

Core Product Features

1. Low-consumption and Stable Operation: Utilizing high-permeability silicon steel sheets and optimized electromagnetic structure design, no-load and load losses are far lower than industry standards, resulting in low operating noise and minimal heat generation. It can operate stably at full load for extended periods, achieving significant energy savings and greatly reducing long-term power maintenance costs.

2. Maintenance-Free Sealed Design: Utilizing a fully sealed oil tank structure, the insulating oil is isolated from air, effectively delaying oil aging and insulation component wear. Under normal operating conditions, frequent oil changes and maintenance are unnecessary. Suitable for complex outdoor conditions, it boasts exceptional durability.

 

Usage Tips

1. Voltage Adjustment Requires Power Off: The equipment employs a non-excitation voltage regulation structure. All voltage level adjustments must be performed with the power completely off. Live voltage adjustment is strictly prohibited to avoid equipment malfunction and safety hazards.

2. Suitable Installation Environment: The equipment is suitable for installation in environments with altitudes below 1000m and ambient temperatures ranging from -25℃ to 40℃. In humid or dusty environments, proper foundation protection is necessary to extend the equipment’s lifespan.

 

Frequently Asked Questions (FAQ)

Q1: What application scenarios is this equipment suitable for? Can it be used with photovoltaic power distribution systems?

A1: The equipment is mainly suitable for 10kV urban and rural power grids, small and medium-sized factories, residential communities, and small industrial and mining power distribution scenarios. It can perfectly adapt to the power distribution needs of Combined Photovoltaic Substations and can also be paired with High and Low Voltage Switchgear and Electric Power Converter to form a complete power distribution system, demonstrating wide adaptability.

 

Q2: Is the daily maintenance of the equipment complicated? Does it require regular oil changes?

A2: This Oil Immersed Transformer adopts a fully sealed structure, and the insulating oil is not easily oxidized or deteriorated. Under normal operating conditions, regular oil changes are not required; only quarterly checks of the casing seal and wiring status are needed, resulting in extremely low maintenance costs.

 

Q3: What is the difference between off-load voltage regulation and on-load voltage regulation? Is it suitable for my project?

A3: The no-load voltage regulator requires power off to adjust the range. It has a simple structure, lower cost, and lower failure rate, making it suitable for small to medium-sized projects with stable voltage fluctuations and no need for real-time voltage adjustment. The on-load voltage regulator allows for voltage adjustment while the load is running, adapting to large-scale scenarios with large load fluctuations. This model offers better cost-effectiveness for most small and medium-sized power distribution projects.

 

Q4: What is the product’s after-sales warranty period? How are malfunctions handled?

A4: The equipment comes with a standard warranty service. During the warranty period, non-human-caused damage can be repaired free of charge, and parts can be replaced. Users can contact the after-sales team at any time to obtain comprehensive services such as troubleshooting, remote guidance, and factory repair, ensuring the continuous and stable operation of the equipment.
