Composite jacket metal zinc oxide surge arresters

Yueqing Deng Rui Electric Co., Ltd.supply various specifications of the [Composite jacket metal zinc oxide surge arresters] products, providing professional [Composite jacket metal zinc oxide surge arresters] prices, models, pictures, factory direct supplier prices have obvious advantages, find [Composite jacket metal zinc oxide surge arresters] manufacturers, we chose Dengrui electrical, please contact us!


Composite jacket metal zinc oxide surge arresters Introduction
Composite coat metal zinc oxide surge arresters using microcomputer sampling, control and other advanced technology to measure the full current of the composite coat metal zinc oxide surge arresters in the power frequency voltage, resistive, resistive current peak capacitive current, the third harmonic, active power and so on. Composite coat metal zinc oxide arrester is the 1970s developed a new type of lightning arrester, it is mainly composed of zinc oxide varistors. A varistor is made when there is a certain switching voltage in the normal operating voltage varistor value very equivalent to the insulating state, but the role of impulse voltage was low hit in the varistor wear equivalent to short-circuit state. However, the varistor hit in the state can be restored; When the revocation of the voltage higher than the varistor voltage, it restored the high impedance state. Therefore, installed in the power line, such as zinc oxide surge arresters, lightning strikes, lightning-wave high-voltage make varistor breakdown, the lightning current into the earth through the varistor, the power line voltage control in a safe range, which to protect the safety of electrical equipment.

Features of composite coat metal zinc oxide surge arresters
The core components of the composite coat metal zinc oxide arrester insulation jacket zinc oxide-based multi-element metal oxide powder to burn, has excellent non-linear V - A characteristics, the steep wave fast response and flow capacity. Clearance products boast the gap with the pressure of radiation structure, reducing the dispersion of the discharge, the impact coefficient is small, and conforms to the development trend of international electricity product miniaturization, safety, maintenance-free, organic polymer composite materials with traditional compared to inorganic materials such as ceramics and glass, has the advantage of light weight, small size, the filthy-free cleaning, explosion-proof anti-vibration. Integrated, modular, high voltage power transmission equipment preferred lightning protection components. Arrester is usually connected between the live conductors and ground, and protect the device in parallel. When the voltage value of action to achieve the required voltage, the arrester immediately action, flows through the charge, limiting the amplitude of voltage protection equipment insulation; normal voltage, the arrester and rapid restitution in order to ensure the normal power supply.
