Abstract

The invention provides a ceramic capacitor material used for sharing voltage for the manganese dioxide lightning arrester consisting of manganese dioxide (MnO2) 60-60%, strontium titanate (SrTiO3) 20-24%, lead titanate (PbTiO3) 8-10%, magnesium titanate (MgTiO3) 4-8%, zinc oxide (Zn0) 8-12%. Adopting this formula, the dielectric constant of the capacitance material can be increased to 2800, the loss of the medium can be less than 0.00012, and the rate of change of the high temperature stability capacitance is less than 8% following the temperature, in addition, the capacitance material has good lightning-protection and voltage-sharing function.

Description

technical field [0001] The invention relates to a capacitor material, especially a high-voltage ceramic capacitor material. Background technique [0002] Because it is easy to generate high temperature and high pressure when lightning strikes, most of the current high-voltage capacitors work in a low temperature range at high temperatures, and the temperature change rate is too high at high temperatures, which cannot be used in lightning rods and other equipment. Contents of the invention [0003] The object of the present invention is to provide a high-voltage ceramic capacitor material which is less affected by temperature and has strong stability. [0004] Manganese dioxide lightning arrester voltage equalization ceramic capacitor material is characterized in that it is made of manganese dioxide MnO 2 60-60%, strontium titanate SrTiO 3 20~24%, lead titanate PbTiO 3 8-10%, magnesium titanate MgTiO 3 High-voltage ceramic capacitor material composed of 4-8%, zinc oxide...
