The 110 kV series oil-immersed power transformer was developed by Daelim to meet the needs of urban and rural power grid transformation and market energy saving. It is based on digesting and absorbing the technology of many transformer manufacturers, adopting mature technology and new insulation, electromagnetic force, Optimized by basic research results such as temperature field.
110 kV series oil-immersed power transformers have passed CSA, IEEE, ANSI, IEC international certifications to ensure that the transformer you buy perfectly meets your market needs.
The design of 110 kV series oil-immersed power transformers is based on ensuring the insulation margin of the product and ensuring the safe and reliable operation of the transformer.
Computer electromagnetic optimization and structural optimization are used to reduce product loss, noise, and partial discharge.
The transformer adopts the ingenious design of the oil circuit and uses non-oriented cooling technology to avoid the risk of electrification of the oil flow inside the transformer under the premise of ensuring the low-temperature rise of the oil level and windings.
The iron core is made of a high-quality cold-rolled grain-oriented silicon steel sheet, adopts a fully oblique non-porous structure, and uses a low magnetic steel plate as a pull plate.
The upper and lower clamps and the iron core are firmly connected into a steel structure to obtain a relatively high Small no-load loss and low noise.
According to the size of the transformer capacity, the winding adopts cylindrical, spiral, continuous, and other structures. For windings of 110kV and above, the tangled or inner screen structure is adopted to effectively improve the impulse voltage distribution.
The wire adopts transposed wire or composite wire to reduce the additional loss of the winding and uses computer simulation to calculate the electric field and the impact characteristics of the winding to ensure the excellent electrical characteristics and impact strength of the winding.
In the process, effective measures are taken to ensure its safety. , Reliable operation.
The compression structure of the transformer body adopts a full-circle insulating pressing plate.
The packaging process adopts the integral assembly of windings, thereby improving the reliability of the product.
The fuel tank adopts a flat-top bell-shaped structure, and the wall of the tank is welded with a folded plate type strengthening iron, which improves the mechanical strength of the fuel tank.
In order to reduce the stray loss of the transformer, the large transformer is equipped with a magnetic shield on the inner wall of the fuel tank.
In order to prevent the transformer body from displacing during transportation, the body is equipped with a positioning device in the oil tank.
A sealed oil conservator is used to isolate the transformer oil from the atmosphere to avoid oil dampness and aging.
The end is equipped with an indicator oil level gauge. According to the oil weight of the transformer, a pressure relief valve is installed on the top of the oil tank to ensure the safe operation of the product.
