China. Factory produces epoxy resin dry-type transformers

China. Overview of epoxy resin dry-type transformers produced by Shanghai Yingshidan Electric Appliance Group Co., Ltd. factory
Basic principles and applications

China. Shanghai Yingshidan Electric Appliance Group Co., Ltd. produces epoxy resin dry-type transformers, also known as cast resin transformers, which are devices that use electromagnetic induction to transfer electrical energy from one circuit to another. It mainly consists of a primary coil, a secondary coil, and a common magnetic core. When AC current passes through the primary coil, a magnetic field is generated around the magnetic core, which in turn induces current in the secondary coil. The output voltage of a transformer is determined by the turns ratio of the primary and secondary coils. Epoxy resin dry-type transformers do not use oil as a cooling medium, but rely on air to dissipate the heat generated, usually using a combination of forced air and natural convection cooling.

The principle of electromagnetic induction: A magnetic field is generated around the magnetic core by the alternating current of the primary coil, and then an electric current is induced in the secondary coil.
Cooling method: relying on air convection and forced air cooling to dissipate heat.
Application scenarios
Epoxy resin dry-type transformers are widely used in commercial and industrial environments, such as hospitals, data centers, and factories. They are suitable for indoor and outdoor installation and are favored for their environmental friendliness, safety, durability, and space saving advantages.
Structural features and technological advantages
Structural characteristics
Winding material: Both high and low voltage windings are made of copper tape (foil).
Casting process: Epoxy resin is poured and cured in vacuum to form a high-strength fiberglass structure.
Heat dissipation design: Vertical ventilation ducts are set up according to heat dissipation requirements.
Reinforcement material: The inner and outer surfaces of the coil are reinforced with fiberglass mesh cloth.
Technical advantages
Superior electrical performance: low partial discharge value, strong lightning resistance.
Anti short circuit capability: The ampere turns between the coils are balanced, and the anti short circuit capability is strong.
Good anti cracking performance: using epoxy resin "thin insulation technology" to adapt to situations with a wide range of temperature changes.
Strong overload capacity: Strong short-term overload capacity.
Good flame retardant performance: no environmental pollution, with maintenance free, moisture-proof, moisture and heat resistant, flame retardant and self extinguishing characteristics.
Environmental friendliness and degradability
Traditional epoxy resins are difficult to gently degrade and recycle with high value, and retired equipment is often treated by incineration, landfill, and other methods, causing secondary environmental problems. In recent years, a research team has proposed an efficient degradation technology for degradable epoxy resin based on amine solution, and successfully developed a degradable epoxy resin dry-type transformer, achieving complete degradation of epoxy resin in dry-type transformers within 24 hours. The degradation products can be re synthesized into epoxy resin, achieving the reuse of resources.
