AI Technical Summary

Problems solved by technology

[0004] The study found that the main reason affecting the flow capacity of the resistor is that the internal microscopic structure of the valve plate leads to the uneven current distribution, and the heat generated thereby leads to the formation of internal thermal stress, which causes the valve plate to break down or burst

The invention relates to an additive used for a nano composite praseodymium-system zinc oxide resistance chip. The additive comprises the following components in parts by weight: 1-3 parts of nano NiO, 2.0-3.0 parts of Al(NO3)3, 1-5 parts of AgNO3, 1-2 parts of nano ZrO2, 1-2 parts of praseodymium-system oxide, 4-10 parts of glass powder, 1-2 parts of Co2O3, 2-3 parts of Cr2O3, 4-5 parts of B2O3, and 1-3 parts of CaCO3. The addictive employs a leadless formula, nano NiO, Al(NO3)3, AgNO3, ZrO2, praseodymium-system oxide, glass powder, Co2O3, Cr2O3, B2O3, and the CaCO3 modifier are added, and the addictive is suitable for producing the medium-voltage high-power zinc oxide resistance chip; and the prepared medium-voltage high-power zinc oxide resistance chip prepared by the medium material has the characteristics of high voltage, high nonlinear coefficient and stable performance.

Description

technical field [0001] The invention relates to an auxiliary material for a direct-current zinc oxide resistor, in particular to an additive for a nanocomposite praseodymium-based zinc oxide resistor, and belongs to the technical field of resistor auxiliary materials. Background technique [0002] my country's economy is in the process of rapid development, the demand for electricity is growing rapidly, and the distribution of my country's power resources is unbalanced. In order to adjust this situation, it is necessary to establish a long-distance, large-capacity transmission system, so it is necessary to develop UHV transmission projects. In 2009, my country's first UHV transmission line, Jindongnan, Nanyang, and Jingmen UHV AC test demonstration line projects were energized and trial run, thermal power from Shanxi entered Hubei through 1000kV UHV transmission lines for the first time, and the two major power grids in North China and Central China were realized for the firs...
