Product Description

10kv ceramic zinc oxide lightning arrester HY5WZ-17/45

Scope of application:
AC gapless metal oxide surge arrester is used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltage and operational overvoltage damage. Applicable to transformers, transmission lines, distribution panels, switchgear, power measurement boxes, vacuum switches, shunt compensation capacitors, rotating motors and semiconductor devices, etc. Overvoltage protection.HY5WZ-17/45Q fully insulated zinc oxide lightning arrester (with insulated cables) is mainly suitable for 10KV switchgear.

Features and principles of fully insulated zinc oxide surge arrester
AC gapless metal oxide surge arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no renewal current, large current capacity, low residual voltage, strong overvoltage suppression capability, dirt resistance, aging resistance, not subject to altitude constraints, simple structure, no gap, tight sealing, long service life and other characteristics.
Zinc oxide lightning arrester in the normal system operating voltage, showing high resistance state, only microampere current through. Under the action of overvoltage and high current, it presents low resistance, thus limiting the residual voltage at both ends of the arrester.

10kv ceramic zinc oxide surge arrester HY5WZ-17/45 is a surge arrester with good protection performance.
The use of zinc oxide good nonlinear volt-ampere characteristics, so that the current flowing through the arrester in the normal operating voltage is very small (ampere or milliampere level); when the overvoltage effect, the resistance drops sharply, the energy of the overvoltage is discharged, to achieve the effect of protection. The difference between this type of lightning arrester and the traditional lightning arrester is that it does not have a discharge gap, the use of zinc oxide non-linear characteristics of the current discharge and disconnection role. Zinc oxide lightning arrester is a new type of lightning arrester developed in the seventies, it is mainly composed of zinc oxide varistor.
Each piece of piezoresistor from the time of making it a certain switching voltage (called piezoresistor voltage), in the normal operating voltage (that is, less than the piezoresistor voltage) piezoresistor value is very large, equivalent to the insulating state, but in the impact voltage (greater than the piezoresistor voltage), the piezoresistor is a low value of breakdown, equivalent to the short-circuit state. However, the piezoresistor can be restored to the insulated state after being struck; when the voltage higher than the piezoresistive voltage is withdrawn, it restores the high resistance state. Therefore, such as the installation of zinc oxide lightning arrester on the power line, when a lightning strike, the high voltage of the lightning wave to make the piezoresistor breakdown, the lightning current flows through the piezoresistor into the earth, can be controlled in the power line voltage within the safe range, thus protecting the safety of electrical equipment.
