Abstract
The utility model discloses a shielding and isolating layer of a high-power high-frequency impulse high-voltage rectifier transformer. The shielding and isolating layer is of thin copper foil, and the surface of the thin copper foil is coated with a teflon layer. The peripheral section shape of the teflon layer coating the thin copper foil is of a spherical structure. The peripheral shape of the thin copper foil is of an arc-shaped structure. The shielding and isolating layer can prevent secondary high voltage from passing through a distributing capacity coupling to a low-voltage winding to cause the damage of a primary inverter switching circuit.
Description
Technical field
The utility model relates to a kind of high-power high-frequency high voltage pulse rectifier transformer shielding separator.
Background technology
Existing a kind of high-power high-frequency high voltage pulse rectifier transformer for electric cleaner, contain cored, the low pressure winding, the high pressure winding, rectifier bridge, oil tank of transformer, iron core adopts rectangle ferrite or the ultracrystallite transformer core that contains long limit and minor face, the low pressure winding divides on two groups of equidirectional two low pressure skeletons that are around on the long limit of iron core with wide Copper Foil, the high pressure sub-winding of half quantity in the high pressure winding is wound on the high voltage ring skeleton successively, the high pressure sub-winding of second half quantity in the high pressure winding is successively on another high voltage ring skeleton, two high voltage ring skeletons are set on two low pressure windings, each high pressure sub-winding in the high pressure winding is connected with input from supporting rectifier bridge respectively, the positive pressure side of the transformer output after the output of each rectifier bridge is connected successively is connected with transformer case, and the negative pressure end of transformer output is connected with high-voltage output end.Because unshielded layer between low pressure winding and the high pressure winding, therefore can't avoid secondary high voltage to pass through that distributed capacitance is coupled to the low pressure winding and the damage that causes elementary inverse switch circuit.
The utility model content
The technical problems to be solved in the utility model provides a kind of high-power high-frequency high voltage pulse rectifier transformer shielding separator, and it can avoid the damage of elementary inverse switch circuit.
For solving the problems of the technologies described above, a kind of high-power high-frequency high voltage pulse of the utility model rectifier transformer shields separator, and this shielding separator is thin copper foil, scribbles polytetrafluoroethylene floor on the surface of this thin copper foil.
The described peripheral cross sectional shape that is coated in the polytetrafluoroethylene floor on the thin copper foil is spherical structure.
The peripheral shape of described thin copper foil is arcuate structure.
Above-mentioned shielding separator is when reality is used, be arranged between the high pressure winding and low pressure winding of high-power high-frequency high voltage pulse rectifier transformer, owing between high pressure winding and low pressure winding, be provided with above-mentioned shielding separator, therefore can avoid the secondary high voltage of prior art to be coupled to the low pressure winding through distributed capacitance and cause the deficiency of elementary inverse switch circuit damage.
