Custom Single-phase oil-immersed transformer Manufacturers, Suppliers

The single-phase oil-immersed transformer is a type of transformer that uses transformer oil as both insulation and cooling medium to convert electrical energy from one voltage level to another. They are widely used in power systems, power supply in remote areas, industrial applications, and testing and inspection, and are characterized by their compact structure, stable performance, and cost-effectiveness.

Product Description

Main Features and Composition

Insulation and Cooling: Transformer oil is used as both an insulating material and a cooling medium for the internal windings and core of the transformer, effectively dissipating heat.

Structural Components: Mainly includes the core, high and low voltage windings, oil tank, radiator, insulating bushings, etc.

Core: Typically made of high-quality cold-rolled silicon steel sheets to reduce hysteresis and eddy current losses.

Windings: Winded from insulated conductors (such as enameled wire), with the low-voltage winding usually on the outside.

Oil Tank: A steel oil tank to house the core, windings, and insulating oil, and equipped with accessories such as an oil level gauge and thermometer.

Application Scenarios

Power Systems: Used in remote areas or special situations where single-phase power supply is unavailable, to convert high-voltage electricity to a voltage suitable for user use.

Industrial Sector: Provides power to industrial equipment requiring single-phase high-voltage power, such as small electric furnaces or single-phase motors.

Testing and Inspection: Used as a high-voltage supply device in electrical equipment testing and inspection, for insulation withstand voltage tests, etc.

Rural Power Grid Upgrading: Suitable for power grid upgrading projects in rural and mountainous areas, reducing line losses and improving power supply quality.

Advantages

High Energy Efficiency: Compared to traditional single-phase transformers, certain designs (such as high-efficiency energy-saving wound cores) can achieve higher energy efficiency.

High Cost-Effectiveness: Pole-mounted installation reduces infrastructure investment, making it particularly suitable for areas with dispersed power supply.

High Reliability: Utilizing a fully sealed structure, it boasts strong overload capacity, high operational reliability, and simple maintenance.

Frequently Asked Questions

1. What is the primary function of oil in a single-phase transformer?
Transformer oil serves two critical purposes: it provides high-grade electrical insulation between internal components and acts as a coolant to dissipate heat generated during operation.
2. Why are these transformers ideal for rural power grids?
They are specifically designed for pole-mounted installation, which reduces infrastructure costs. This makes them highly cost-effective for providing stable power to dispersed populations in mountainous or rural areas.
3. What materials are used in the core construction?
The core is typically constructed from high-quality cold-rolled silicon steel sheets, which are chosen to minimize energy losses like hysteresis and eddy currents.
4. Is maintenance difficult for these oil-immersed units?
No, these transformers feature a fully sealed structure. This design protects the internal components from environmental contaminants, resulting in high operational reliability and very low maintenance requirements.
5. Can these transformers handle industrial equipment?
Yes, they are suitable for providing single-phase high-voltage power to specific industrial tools, such as small electric furnaces, motors, and testing equipment for insulation withstand tests.
6. How is the oil level monitored?
The steel oil tank is equipped with specialized accessories, including an oil level gauge for visual inspection and a thermometer to monitor the operating temperature of the oil.
