10kV oil-immersed three-dimensional winding core distribution transformer
Product Introduction
This series of three-dimensional coil core transformer is an energy-saving power transformer, which creatively reforms the laminated magnetic circuit structure and three-phase layout of the traditional power transformer. Because its three legs are arranged in a three-dimensional equilateral triangle, there is no air gap in the magnetic circuit, and the winding is more compact. The lengths of the three magnetic circuits are the same and the shortest, and the cross-sectional area of the core legs is closer to a circle.So the performance is further improved with the loss reducing, the noise reducing, the three items balancing, and the third harmonic component reducing.
Product Model
Product Features
The magnetic circuit is evenly distributed everywhere. There is no obvious high resistance area, there is no distortion of magnetic flux density at the joints, and the three-phase magnetic circuit is completely symmetrical.
Three-dimensional coil core is a kind of wound core. The whole iron core is assembled by three identical single frames. The assembled equilateral triangle three-dimensional structure has good stability, high mechanical strength of the iron core, and the three-phase stress is consistent, which enhances the short-circuit resistance of the body. The three core columns of the assembled iron core are arranged in equilateral triangle three-dimensional.
After vacuum annealing in the manufacturing process, the internal stress can be basically eliminated, and there is no high reluctance everywhere in the magnetic circuit, which greatly reduces the no-load loss and no-load current.
The iron core is wound continuously without seam, and the structure of silicon steel strip is compact, and the working vibration is small, which can reduce the noise to a minimum.
The three-phase magnetic circuit of iron core is coherent, and it is shortest than laminated iron core and planar wound iron core transformer, which ensures the balance of three-phase power supply and makes the loss reduction effect remarkable.
The products are energy-saving, low in consumption, low in operating cost and high in cost performance, which fully Applicable Conditionss to China's policy of energy conservation and emission reduction.
