Problems solved by technology

[0003] The whole transformer with solid insulation encapsulated winding is covered with epoxy resin. The heat generated by the transformer winding can only be transmitted to the air after many barriers, resulting in the temperature of the winding being much higher than that of the outer sealing material, and the heat dissipation is not good.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] In Fig. 1 and Fig. 2, the high and low voltage coils 2 and 3 are arranged in the shell 1, and the high and low voltage coils 2 and 3 are wound between them, and the insulating cylinder 4 is arranged between the high and low voltage coils 2 and 3, and the insulating cylinder 4 is provided with an axial ventilation hole 5, and the low-voltage coil 3 is multi-coiled and wound in layers, and both the turn insulation and the interlayer insulation are potted with epoxy resin. The high-voltage coil 2 is cake-shaped, and comb-shaped stays are used between the wire cakes, which reduces the maximum voltage between the cakes by half and greatly improves the axial short-circuit resistance of the high-voltage coil 2 . The high and low voltage coils 2 and 3 are wrapped around, which enhances the mechanical strength and reduces the leakage inductance. The insu...

Abstract

The invention relates to a dry-type transformer used for an ozone generator, which comprises a casing, a high-tension coil and a low-tension coil. The high-tension coil and the low-tension coil are arranged inside the casing and are wound to enhance mechanical strength and reduce leakage inductance. An insulating cylinder is arranged between the high-tension coil and the low-tension coil, and an axial ventilation heat radiating hole is formed on the insulating cylinder. A shielding layer is arranged outside the casing to effectively reduce the influence of electromagnetic radiation on the surroundings. The inventive dry-type transformer has a large contact area between the high-tension/low-tension coil and the air, thereby having the advantages of good heat radiating and ventilation performance and strong overload capacity, having larger redundancy of coil temperature rise due to the limitation of load loss sometimes, and further improving the reliability of the transformer. Moreover, the dry-type transformer reduces the contaminating and damping extents of coils. With the improvement of the insulation treatment process of insulating materials and coils, the wearing and the noise are well controlled.

Description

technical field [0001] The invention relates to a transformer, in particular to a dry-type transformer for an ozone generator. Background technique [0002] At present, the dry-type transformers in use can be divided into two types in terms of structure: solid insulation encapsulated windings and non-encapsulated windings. [0003] The whole transformer with solid insulation encapsulated winding is covered with epoxy resin. The heat generated by the transformer winding can only be transmitted to the air after many barriers, resulting in the temperature of the winding being much higher than that of the outer sealing material, and the heat dissipation is not good. , the copper used in the transformer increases, and the cost increases. [0004] The transformer without encapsulating windings has good heat dissipation because the windings are exposed in the air, but it causes another bad effect, which is easily attacked by dust, pollution and water vapor, the insulation drops, a...
