Abstract

The present invention relates to the field of power transformers, in particular to a transformer core structure and a power transformer, including a casing, a bottom plate cavity, a slotted support frame, a transformer component, etc.; the bottom plate cavity is fixedly installed in the casing, and the A slotted support frame is fixedly installed on the bottom plate chamber, and the pressure transformation component is arranged on the slotted support frame. Through the silicon steel terminal, the silicon steel terminal utilizes the orientation of the silicon steel sheet and adopts the annealing process, which can reduce additional loss and increase the current transmission efficiency. The silicon steel chip uses a high magnetic permeability silicon steel sheet to fully reduce the loss. Stacking can reduce iron loss by about 8%, achieving the purpose of effectively reducing loss.

Description

Technical field [0001] The present invention relates to the field of power transformers, in particular to a transformer core structure and a power transformer. Background [0002] With the rapid development of the entire national economy, the demand for transformers will continue to increase, power transformers are one of the most important equipment in the power system, is the basis for ensuring the reliability of power supply, transformers are composed of two or more coil windings around the same core, the windings are connected by alternating magnetic fields and work according to the principle of electromagnetic induction, transformer installation location should be considered for easy operation, maintenance and transportation, and should choose a safe and reliable place. [0003] The rated capacity of the transformer should be selected according to the needs of the electricity load, the traditional transformer can not control the capacity of the transformer according to the ...
