Main Features and Application Areas of Fully Sealed Oil-Immersed Distribution Transformers

发布时间：2023-08-23

The fully sealed oil-immersed distribution transformer is a special type of transformer with the following key features: 1. Fully sealed construction: This transformer adopts a completely enclosed design, ensuring that the insulating oil inside is entirely sealed and does not come into contact with the external environment. This structure prevents oil contamination and leakage, thereby guaranteeing reliable operation. 2. Oil-immersed cooling: The fully sealed oil-immersed distribution transformer uses oil-immersed cooling, in which the transformer’s heat is dissipated to the surrounding environment through the insulating oil. This cooling method offers excellent heat dissipation and uniform temperature distribution, enhancing the transformer’s operational efficiency and service life. 3. Wide environmental adaptability: The fully sealed oil-immersed distribution transformer is highly adaptable to various environments and can be installed indoors or outdoors, performing reliably under harsh conditions such as high temperatures, low temperatures, and high humidity. 4. Compact size and light weight: Compared with conventional dry-type transformers, the fully sealed oil-immersed distribution transformer is smaller and lighter, occupying less space and facilitating installation and maintenance.

Epoxy-resin dry-type transformers are primarily used in the following applications: 1. Power systems: Dry-type transformers offer high dielectric strength, low energy consumption, compact size, low noise, and high reliability, making them well suited for power transmission, transformation, and distribution within power systems. 2. Industrial sector: These transformers are ideal for industrial power supply and distribution systems, such as those found in factories, mines, and construction sites. 3. Municipal infrastructure: Dry-type transformers can be deployed in urban distribution networks to provide stable and reliable power supply. 4. Wind and solar power generation: They are suitable for wind farms and solar power plants, meeting the demanding operational requirements of transformers in harsh environments. 5. High-speed railways: Dry-type transformers are employed in high-speed railway power supply systems, satisfying the stringent power demands of high-speed trains. 6. Offshore platforms: With their corrosion resistance and moisture-proof properties, these transformers are well-suited for power supply in humid and corrosive environments, such as offshore oil and gas platforms. In summary, epoxy-resin dry-type transformers are widely used in power systems, the industrial sector, municipal infrastructure, and new-energy power generation, providing stable and reliable power supply across various fields.

Transformer Manufacturer – Transformer Overview

发布时间：2023-08-07

A transformer is a device used to change the voltage of an alternating current. It consists of two or more coils that transfer electrical energy by sharing a common magnetic field. One coil, called the primary winding, receives current from the original power source, while the other coil, called the secondary winding, delivers the transformed voltage. The operating principle of a transformer is based on Faraday’s law of electromagnetic induction: when the primary winding is connected to an AC power source, the resulting magnetic field passes through the secondary winding, thereby inducing a current in the secondary winding.
