A high temperature resistant and anti-corrosion transformer

Abstract

The invention relates to a high-temperature-resistant anticorrosive transformer which is formed by filling insulation potting wax with favorable liquid flowability into transformer gaps. The insulation potting wax comprises 72-78% of petroleum wax, 2-4% of polyethylene wax, 9-13% of tackifier and 9-13% of vaseline. The high-temperature-resistant anticorrosive transformer has the characteristics of excellent high temperature property, excellent corrosion resistance, favorable electric properties, favorable moisture resistance and the like. The insulation potting wax is not only suitable for insulation impregnation potting of electronic transformers and high-frequency transformers, but also suitable for insulation impregnation potting of inductive coils and other special coils for electronic components.

Description

technical field [0001] The invention relates to a high-temperature-resistant and anti-corrosion transformer, in particular to a high-temperature-resistant, anti-corrosion, and moisture-proof electronic transformer and a high-frequency transformer made by filling the transformer gap with insulating potting wax. Background technique [0002] In the production of transformers, it is often necessary to use insulating potting wax to impregnate and pot the transformer to improve the insulation performance of the transformer. In the prior art, commercial paraffin or microcrystalline wax is simply used. Although the price is cheap, there are defects such as poor high-temperature performance and toughness and plasticity. Potting transformers with oil is prone to leakage. The use of resin materials can make the transformer have good high temperature resistance, but it has defects such as poor toughness and plasticity and high production cost, which cannot meet the requirements of cur...

[0004] Invention patent CN1458216A discloses a sealing wax for electronic components, including petroleum wax, polymer wax, tackifier and plasticizer, mainly used for positioning and sealing of electronic tuners, inductor coils and other electronic component coils. However, for electronic transformers and high-frequency transformers with high requirements for liquid fluidity and dielectric loss, insulation impregnation and potting cannot make them have the best performance.
