Description

A kind of leakage transformer
Technical field
The present invention relates to a kind of leakage transformer.
Background technology
Leakage transformer belongs to the category of leakage field boosting dry-type transformer, drastically changes for loading and requires progressively to become In the electronic equipment of stable state, such as fluorescent lamp power supply, ion pump power equipment;This one kind load shows as starting working When impedance it is larger, it is necessary to higher transient voltage;And when steady operation, load impedance is smaller, need to be limited in load current In permissible value, with can normal work;Existing leakage transformer generally existing unreasonable structure, causes to take up too much space, The problems such as radiating effect is poor.
The content of the invention
For above-mentioned technical problem, the purpose of the present invention is:Propose a kind of space and account for smaller, heat dispersion Good leakage transformer.
What the technical solution of the present invention was realized in:A kind of leakage transformer, comprising shell, it is provided with shell Main iron core, coil is provided with main iron core;The shell includes upper clamping piece, lower clamping piece and the side of connection upper clamping piece and lower clamping piece and pressed from both sides Part;Hanging rod is provided between the upper clamping piece and lower clamping piece, radiating notch is provided with upper clamping piece, hanging rod is arranged on radiating The downside of notch.
Preferably, the main iron core includes three stems, and 3 coils, radiating notch position are respectively arranged with three stems It is symmetrical arranged in the top of the intersection of the adjacent coil of each two, and in the front and rear sides of upper clamping piece.
Preferably, the coil includes exterior loop and interior loop, sets cored mating groove in the middle part of interior loop, interior loop with It is provided with cross-over block and secondary iron core between exterior loop, the contact in exterior loop and interior loop is arranged at the same side.
Preferably, the secondary iron core includes end iron core and middle iron core, and end iron core is separately positioned on upper and lower ends, more Individual middle iron core is arranged between two end iron cores, and air gap, end iron core and phase are provided between iron core among each two Air gap is also equipped between near middle iron core;The front and rear sides of the secondary iron core are provided with thin stainless steel arm-tie, thin stainless Insulation board is provided with the outside of steel arm-tie.
Preferably, the air gap between the end iron core and middle iron core is less than the air gap between middle iron core.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art:
The leakage transformer of the present invention, the radiating effect of coil is improved by the radiating notch on upper clamping piece, and hung tight The lower section of the radiating notch of bar income indent, the space of both sides occupancy being reduced, upper clamping piece is connected with lower clamping piece by side folder, Stability is improved, overall structure is simple, reasonable, and is easy to assemble.
