Maximum Demand Meter
The single structure maximum demand panel meter is dual metal structure. It’s used for measuring Max. average current of all kinds of AC/DC transmission systems and electric equipment controlled by the power plant in the demand cycle.
Metal Oxide Resistor
As the core part of surge arrester, metal oxide resistor is made according to the following procedure: add a little bismuth oxide, cobalt oxide, chromium oxide, manganese carbonate, stibium oxide and other microcrystalline additives to the main component-zinc oxide and then burn in high temperature at 1200℃.
Metal oxide resistor mainly consists of zinc oxide grain, crystal boundary layer and spinel. It's generally considered that zinc grain has better conductivity; the voltage upon zinc oxide grain nearly totally affect on high resistant crystal layer(taking bismuth oxide as main component).Spinel ,as the component oxide made up of zinc oxide and stibium oxide distributions in the crystal boundary layer to limit the growing of zinc oxide grain and make resistor of better nonlinear characteristics. CHINT metal oxide resistor features flat v-t characteristics curves within large current range and superior nonlinear. It also features for excellent over voltage protection level due to its low residual voltage and large current passing capacity and is widely used in all kinds of surge arresters to absorb the energy in over voltage system.
