Description
Technical field
The invention belongs to high-temperature refractory manufacturing technology field, in particular it relates to which a kind of be used for Zinc-Oxide Arrester valve
The exotic material and preparation method of piece.
Background technology
Zinc-Oxide Arrester is the arrester with good protection performance.It is special using the good non-linear volt-ampere of zinc oxide
Property, make the electric current for flowing through arrester in normal working voltage minimum（Microampere or milliampere level）；When overvoltage is acted on, resistance is anxious
Play declines, and the energy for overvoltage of releasing reaches the effect of protection.The difference of this arrester and traditional arrester is that it does not have
Discharging gap, plays a part of aerial drainage using the nonlinear characteristic of zinc oxide and cut-offs.
Zinc oxide valve plate is also known as piezo-resistance, with more excellent than carborundum in more preferably nonlinear resistance property.
Under system operation voltage, its resistance is very big, the electric current very little passed through, and resistive component is only 10-15uA or so, so small electricity
Stream will not burn out valve block, therefore can isolate power frequency operation voltage without series gap;When the voltage increases, its resistance becomes
Very little is obtained, can be by high current, after residual voltage is also very low, is protected equipment, and overvoltage disappears, it recovers former again
Shape.Zinc-Oxide Arrester valve block is by semiconductor oxide zinc and other metal oxides（Such as oxidation brill, manganese oxide）In high temperature
（More than 1000 DEG C）Lower sintering is formed.Generally sintered with corundum as high-temperature refractory, but be due to that corundum mutually expands and is
