CN201430062Y - High-tension output transformer - Google Patents

Abstract

The utility model discloses a high-tension output transformer which comprises a magnetic core, a framework shell, a framework inner core, enameled wires, adhesive tape wound on the magnetic core and pins, wherein baffle walls are respectively arranged on the periphery of the framework shell close to pins of a coil. The high-tension output transformer has more reliable safety performance.

Description

The high pressure output transformer

Technical field

The utility model relates to a kind of transformer, particularly a kind of high pressure output transformer.

Background technology

At present, transformer is because of volume is little, in light weight, cost is low, steady performance is widely used, existing kind is tired many, pattern is different, and the existing high pressure output transformer skeleton shell upper edge commonly used and the distance at high pressure pin place are about 3mm, make easily between pin and the magnetic core creepage phenomenon to occur, cause high-voltage breakdown and whole circuit is damaged.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of high pressure output transformer, and security performance is more reliable.

The utility model technical scheme that adopts of dealing with problems is: a kind of high pressure output transformer, comprise magnetic core, skeleton shell, skeleton inner core, enamelled wire, be wound on adhesive tape, stitch on the magnetic core, around described skeleton shell, be provided with barricade respectively near the coil pin place.

Enamelled wire is wound in the winding slot of skeleton inner core in the utility model, enamelled wire after line system is finished and stitch scolding tin, in the skeleton of then magnetic core being packed into, and the magnetic core outer ring around on adhesive tape, carry out dipping lacquer again.

The beneficial effects of the utility model are: be provided with barricade respectively near the coil pin place around the skeleton shell, can avoid creepage phenomenon occurring between pin and the magnetic core, guaranteed that coil is when high-pressure work and the fail safe of magnetic core.
