Description
Technical field
The present invention relates to the preparation method of Zinc-Oxide Arrester valve block, repair particularly to using cutting process method
The preparation method of the Zinc-Oxide Arrester valve block of the most described zinc oxide smooth shape of magnet end face and shape.
Background technology
Zinc-Oxide Arrester has special nonlinear current-voltage.Unusual condition is once there is in using,
Such as power circuit meets with thunderbolt, strong-electromagnetic field disturbs, on and off switch frequent movement, power system failure,
Make voltage spikes on circuit, exceed the conducting voltage of spark gap, conducting district will be entered.Now electric current (I)
With voltage (V) in non-linear relation, commonly referred to as nonlinear factor (Nonlinearity Parameter), its
Value is up to tens of or up to a hundred.Now, the impedance of spark gap can drastically decline, and the most several ohms made electricity
Swaging becomes burst current to flow out, the energy of overvoltage of releasing, and uses all kinds of high and low voltage electric distributions that protection is connected,
Converting equipment.
Regular oxidation zinc spark gap material is through dispensing, grinding, pelletize, molding, binder removal, upper resistive formation, height
Temperature sintering, glazing operation after, formed zinc oxide magnet, its hardness is about 7 grades, the third constellations, Lip river, with ceramic phase
Seemingly.Owing to burning till through about 1200 DEG C of high temperature, zinc oxide magnet all can some deformation, its end face need to be revised
Flatness.
At present, generally use grinder to add mode that abrasive disk is ground is processed and is revised zinc oxide magnetic
The shape of body.The method of attrition process there is the problem that
First, time-consumingly, such as processing oneCylindrical two transverse planes of 40 × 25mm, need the most about 6 points
Clock；
Second, the sewage that in process of lapping, corundum and lapping liquid, cooling water are formed is not easily recycled, is difficult to locate
Reason, causes environmental pollution.
