Description

A kind of transformer
Technical field
The utility model relates to transformer, relates in particular to a kind of transformer.
Background technology
In electric equipment and radio-circuit, transformer is commonly used for lifting voltage, matched impedance, safety isolation etc.Leakage inductance is an important indicator of transformer, and is very big to performance indexes, and the existence of leakage inductance can make circuit produce vibration and outside electromagnetic radiation energy, causes electromagnetic interference.
Traditional transformer adopts the method for plane lapping usually, adds air-gap in magnetic circuit, to increase magnetic resistance, avoid occurring magnetic saturation, but can cause very big radiated interference, also produce local loss and generate heat at the air gap incision position, cause magnetic to worsen even disappear.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of transformer is provided, and the magnetic core inboard grinds to form the inclined-plane, does not have the gap between magnetic core, neither destroys magnetic circuit, can effectively regulate the control leakage inductance again, avoids magnetic saturation; But derate is used, and improves stability, is conducive to slow down performance degradation.
For achieving the above object, the utility model by the following technical solutions:
A kind of transformer comprises magnetic core, skeleton, the first elementary winding, the second elementary winding, the 3rd elementary winding, secondary winding, and the magnetic core inboard grinds to form the inclined-plane; The inclined-plane of magnetic core and vertical plane angle are 3~4 degree; Magnetic core is installed in the skeleton both sides; Magnetic core, skeleton, the first elementary winding, the second elementary winding, the 3rd elementary winding, secondary winding are around on the skeleton.
Described magnetic core inboard grinds to form the inclined-plane, and the inclined-plane of magnetic core and vertical plane angle are 3~4 degree, can avoid magnetic saturation, do not have the gap between magnetic core, neither destroy magnetic circuit, can effectively regulate the control leakage inductance again.
Described magnetic core is installed in the skeleton both sides; Magnetic core, skeleton, the first elementary winding, the second elementary winding, the 3rd elementary winding, secondary winding are around on the skeleton, but the derate use improves stability, is conducive to slow down performance degradation.
Compared with prior art, the utlity model has following beneficial effect:
1. the increase magnetic resistance avoids occurring magnetic saturation;
2. by bevel ground, do not have the gap between magnetic core, do not destroy magnetic circuit, effectively regulate the control leakage inductance;
3. but derate is used, and improves stability, is conducive to slow down performance degradation.
