Description
Technical field
The utility model belongs to field transformer, and in particular to a kind of high-frequency electrical for high voltagehigh frequency power conversion system
Depressor.
Background technology
High-tension transformer is the conventional electronic equipment of electronic product, is for low frequency low voltage is converted into low frequency high voltage
Equipment.When first side winding is by alternating current, transformer produces alternating magnetic field, secondary by the induction effect of alternating magnetic field
Level winding also produces alternating magnetic field accordingly and produces AC electromotive force, the voltage levels of secondary windings and the number of turn of secondary windings
Than thering is relation, i.e. voltage to be directly proportional to the number of turn, the main function of high pressure be by low voltage transition into required high voltage, wherein
Manufacture process insulation particularly important.
For voltage very high transformer (particularly high frequency transformer), if winding in a mounting groove multilayer around
System, can cause the relative voltage of adjacent two layers very high, it is difficult to solve its Insulation Problems.Therefore, to general high-tension transformer
Speech, in order to reduce the voltage stress of high pressure winding, is divided into multiple windings in series by high voltage winding group and forms, each winding is located at respectively
In different insulation tanks, between adjacent series connection winding, obstructed with insulation barricade, to solve Insulation Problems from each other.
Between adjacent series connection winding, obstructed with insulation barricade, to solve Insulation Problems from each other.
