Abstract
The invention provides a doped and modified ceramic capacitor material for voltage equalization of a zinc oxide doped arrester. The high-voltage ceramic capacitor material consists of 80 to 84 percent of strontium titanate (SrTiO3), 8 to 10 percent of bismuth oxide (BiO), 0.5 to 2 percent of titanium dioxid (TiO2), 0.1 to 1 percent of manganese dioxide (MnO2), 4 to 8 percent of yttrium oxide (Y2O3) and 3 to 5 percent of magnesium titanate (MgTiO3). Due to the formula, the solid capacitance limit of a SrTiO3 lattice is increased, intense peak shifting and widening effects are generated, the capacitance temperature characteristic is improved, the electric constant is increased to 2,500, the medium consumption is less than 0.0001, the change ratio of high-temperature stability capacitance is less than 10 percent along with the temperature change, and excellent lightning protecting and voltage equalizing effects are achieved.
Description
Technical field
The present invention relates to a kind of capacitance material, especially the higfh-tension ceramics capacitance material.
Background technology
Because thunderbolt the time is easy to generate High Temperature High Pressure, present high-voltage capacitance majority is lower in the hot operation temperature range, and rate of temperature change is too high when high temperature, can not satisfy in the equipment such as lightning rod and use, and it is little to hold limit limit admittedly.
Summary of the invention
Purpose of the present invention provides a kind of and is subjected to the solid appearance limit big, the higfh-tension ceramics capacitance material that stability is strong.
A kind of Zinc-Oxide Arrester of doping vario-property is all pressed and is used ceramic capacitor material, it is characterized in that by strontium titanate SrTiO
380～84%, bismuth oxide BiO8-10%, titanium dioxide TiO
20.5-2%, Manganse Dioxide MnO
20.1-1%, yttrium oxide Y
2O
34-8%, magnesium titanate MgTiO
3The high-pressure porcelain capacitor material that 3-5% forms.
Adopt this prescription, just can make and hold limit increase in the strontium titanate lattice admittedly, produce intensive and move peak and broadening effect, improve temperature characteristics of capacitance, improving electric constant simultaneously is 2500, dielectric loss is less than 0.0001, and the high-temperature stability capacity varies with temperature rate and diminishes in 10%, and good lightning-arrest all pressure effects are arranged.
