Abstract
The invention provides a novel high-frequency high-voltage transformer. The novel high-frequency high-voltage transformer is characterized by comprising a framework, a manganese zinc ferrite magnetic core, a primary secondary line winding, a radiating air channel and a protecting layer; the manganese zinc ferrite magnetic core with high frequency and high resistivity is adopted; high-frequency bundling wires which are arranged and wound from inside to outside are used as the winding copper wires of the primary secondary line winding; the high-frequency bundling wires are subjected to interlayer isolation through a epoxy resin chock rod and pieces of dupoint paper; polyester silks and teflon films wrap the outer layers of the high-frequency bundling wires; heat absorbing holes are formed in the radiating air channel. The novel high-frequency high-voltage transformer has the advantages of producing less heat, being fast to radiate, high in isolation performance, and preventing from breakdown.
Description
Technical field
The present invention relates to ozone generating apparatus, particularly a kind of novel high-frequency high-tension transformer.
Background technology
Usually understand using ozone in fields such as water treatment, sewage disposal and chemical industry oxidations and carry out sterilization, sterilization; ozone demand is also increasing; market is also comparatively urgent to the demand of the ozone generator of super large rank (more than 50KG/h), and high-power high-frequency, high-tension transformer are the bottlenecks manufacturing ultra-large type ozone generator.That ultra-large type ozone generator is divided into some independently unit in the market mostly, then corresponding with it with the power transformer of some cover low capacities, mutual interference is large, the utilance of power supply is low, run extremely unstable, and manufacturing cost is higher, and heat radiation is also a problem very much.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of novel high-frequency high-tension transformer.
For solving above technical problem, technical scheme provided by the invention is:
A kind of novel high-frequency high-tension transformer, it is characterized in that, comprise transformer framework, manganese-zinc ferrite core, former vice-side winding, heat dissipation wind channel, protective layer, described manganese-zinc ferrite core is fixed by transformer framework, manganese-zinc ferrite core quantity is 25 pairs, described former vice-side winding comprises former limit winding and vice-side winding, described former limit winding is positioned at below vice-side winding, former limit winding is arranged around forming by high frequency beam envelope in a row from inside to outside, vice-side winding is arranged around forming by high frequency beam envelope in a row from inside to outside, described high frequency beam envelope is φ 0.1 × 1050 strand, high frequency beam envelope outer layer covers has dacron thread and polytetrafluoroethylene membrane, described protective layer is arranged at high frequency beam envelope between row and row, protective layer comprises epoxy resin filler strip and Du Pont's paper, described heat dissipation wind channel quantity is 2 and is arranged between former limit winding and vice-side winding, the side plate up and down of heat dissipation wind channel evenly has multiple heat absorption hole.
Beneficial effect of the present invention is:
One, reduce magnetic core heating: the manganese-zinc ferrite core adopting high frequency, high resistivity, reduce the magnetic core of transformer because of the heating caused by loss;
Two, the heating of former vice-side winding is reduced: the kelvin effect considering transformer electric current under high frequency state, the coiling copper cash of former vice-side winding have employed high frequency beam envelope, heating when transformer runs caused by copper loss obtains effective control, with time-frequency beam envelope row from inside to outside around mode, can effective control transformer leakage inductance, reduce former vice-side winding because of the heating caused by inside transformer circulation;
Three, stop interlayer to puncture: interlayer adopts the epoxy resin filler strip of fire-retardant, high temperature resistant, excellent insulating property and Du Pont's paper to carry out zone isolation, for stopping turn-to-turn short circuit, high frequency beam envelope skin swathes dacron thread and the polytetrafluoroethylene membrane of high temperature resistant, excellent insulating property;
Four, heat extraction performance is good: inside transformer is provided with heat dissipation wind channel, heat dissipation wind channel has heat absorption hole, internal heat is discharged in time, avoid because temperature rise is too high and damage transformer during operation by external air intake device;
Five, leakage inductance is adjusted: the elasticity adjusting the former secondary number of turn and the coupling of former secondary, reaches the object of adjustment leakage inductance, enable ozone generation system carry out resonance under suitable frequency.
