Problems solved by technology

Simply using commercial paraffin wax or microcrystalline wax has defects such as poor toughness and plasticity, brittleness and large shrinkage at low temperatures, and poor oxidation resistance. After the wax is oxidized, its color becomes darker and the overall acid value increases. , will affect the dielectric properties, working stability and service life of the capacitor
The use of oil has a large loss and is easy to leak, which does not meet the requirements of the current production plant

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a metallized film capacitor potting wax with good oxidation resistance. Background technique [0002] In the production of metallized film capacitors, the main dielectric and the pores between the plate and the main dielectric are usually potted with a material to improve capacitance and insulation performance, and improve partial discharge, heat resistance and stability. Simply using commercial paraffin wax or microcrystalline wax has defects such as poor toughness and plasticity, brittleness and large shrinkage at low temperatures, and poor oxidation resistance. After the wax is oxidized, its color becomes darker and the overall acid value increases. , will affect the dielectric properties, working stability and service life of the capacitor. The use of oil has a large loss and is easy to leak, which is not suitable for the requirements of the current production plant. Co...
