The 200kva Three Phase 50Hz Dry Type Transformer is a static power device that converts AC voltage through electromagnetic induction. Its rated capacity is suitable for medium-power distribution needs. Its core consists of a laminated silicon steel core and epoxy resin-encapsulated windings, without any liquid cooling medium.
Three-phase AC input generates alternating magnetic flux in the primary winding. The high-permeability silicon steel core directs the magnetic flux lines. The secondary winding cuts through the magnetic flux lines, inducing an electromotive force. The turns ratio determines the voltage conversion ratio. The epoxy resin encapsulation layer isolates the conductors from air, eliminating the risk of partial discharge. The fully beveled core reduces eddy current losses in the magnetic circuit, resulting in lower no-load current than conventional laminated structures.
1. The 200kva Three Phase 50Hz Dry Type Transformer uses no mineral oil as a cooling medium, reducing fire hazards and meeting fire safety regulations for underground commercial buildings. The epoxy resin's flame retardancy is UL94 V-0 certified, and no toxic gases are released during an arc fault.
2. The IP54 protection rating withstands high-humidity environments, and salt spray corrosion tests exceed industry standards. With no risk of oil leakage, it can be deployed in food processing plants, and the operating noise level is significantly lower than comparable oil-immersed products.
3. No oil filter required for maintenance, saving labor costs, and the winding encapsulation structure allows for cleaning with a damp cloth. The temperature-controlled fan requires no lubrication throughout its lifecycle, with overall maintenance frequency only a fraction of that of oil-immersed fans.
The 200kva Three Phase 50Hz Dry Type Transformer's connector terminals utilize a nickel-zinc alloy multi-layer composite electroplating process, and an optional salt spray-resistant protective cover is available to isolate them from moisture. Regularly apply contact paste to maintain low contact resistance, and mechanical polishing of the plating is strictly prohibited.
The fan modules of the 200kva Three Phase 50Hz Dry Type Transformer utilize a fully sealed bearing design. After a certain period of cumulative operation, they can be replaced without lubrication. The air duct should be cleaned with negative pressure vacuum equipment every quarter, and high-pressure gas is prohibited from blowing directly on the winding surface.
