Abstract

The invention discloses a process for processing an oxide resistor. The process for processing an oxide resistor includes the steps of raw material preparation, raw material preparation, mixing, granulation, water content, forming, sintering, heat treatment, and electrical performance measurement; S1. Raw material preparation: Take 94.7% mol zinc oxide, 0.7% mol bismuth oxide, 1.0% mol cobalt oxide, 0.5% mol manganese oxide, 1.0% mol antimony oxide, 1.0% mol chromium oxide, 0.5% mol nickel oxide, 0.% 5mol silicon oxide and 0.1% mol boric acid. The oxide resistor chip processing technology crushes the material into nanometer shape, improves the uniformity of the mixture, so as to facilitate the combination of raw materials, and increases the moisture content of the material by adding water, so as to avoid dry cracking and damage during the sintering process. The method of dry pressing is used to control the amount of compression of the molding powder in the mold sleeve and slow down the compression speed.

Description

technical field [0001] The invention relates to the technical field of electronic component processing, in particular to a processing technology for an oxide resistance chip. Background technique [0002] Zinc oxide resistors are the core devices of metal oxide voltage limiters in power systems. In order to adapt to the development of high-performance MOVs towards ultra-high voltage, miniaturization, and direct current transmission, zinc oxide resistors are developed to high potential gradients, through The high-performance high-potential gradient with large current capacity, low residual voltage ratio, and excellent aging performance is developed. High-gradient and large-capacity zinc oxide resistors are used to reduce the height and weight of the arrester core, thereby reducing the weight and weight of the entire arrester. Promote the rapid development of the entire power industry. It can be seen from this that it is an important way to improve the safety, reliability, li...
