Description

Technical Field

[0001] This utility model relates to the field of zinc oxide resistor technology, specifically to a zinc oxide resistor pre-fired bowl with easy glue removal. Background Technology

[0002] As a core component of surge arresters, the electrical performance of zinc oxide resistors directly determines the electrical performance of the arrester. Because organic materials such as polyvinyl alcohol are added during the manufacturing process of zinc oxide resistors, if these materials are not completely removed during the adhesive removal process, they will carbonize into the resistor matrix, introducing impurities.

[0003] Existing pre-firing bowls are typically sealed at the bottom, lacking permeability. During the pre-firing process, the resistor sheet blanks may partially adhere to the bottom plate. Due to the insufficient air supply, incomplete glue removal is easily caused. This will significantly increase the defect rate of the resistor sheets during square wave screening, resulting in a decrease in the current carrying capacity of the resistor sheets, an increase in production costs, and the impurities adhering to the bottom plate are inconvenient to clean, affecting later use.
