Descripción del producto

1. Electrical principle: arrester monitor mainly consists of sampling valve, silicon bridge rectifier, high-voltage capacitor, electromagnetic counter, milliammeter and other components. It uses the discharge current of the arrester and the voltage generated on the valve plate (non-linear resistance) to charge through silicon bridge rectifier and discharge to the electromagnetic counter. Each discharge is recorded once to record the action times of the arrester.
2. The shell of this product is made of high-quality die-casting aluminum, and its outer surface has good corrosion resistance after plastic spraying treatment; The sealing performance is superior to that of the stainless steel shell, and is not affected by the external environment. The internal components have good anti-aging performance and can be used in power system for a long time.
