KNFF Lighting Protection Gate Of The Generator For Wind (SPD)
KNFF lighting protection gate of the wind generator is Mainly used for wind power generation, railway transportation, electric power, mining enterprises, large factories, ship, naval ships and other fields. To prevent lightning pulses generated surge and instantaneous over voltage damage to the electrical equipment.
·When the fault occurs, The detection display to change from green to red.
·Without considering the load current, plug design, can be charged for replacement, easy maintenance with check off port device.
·Using the temperature control circuit break technology, high safety performance, continued flow.
·With remote alarm device (S type), convenient for remote monitoring.

Installation And Maintenance
1.DIN 35MM standard rail installation
2.The product adopt the flame - retardant ABS housing,fix the products,connect the power lines and ground lines,examine and power up.
3.Grounding is very important to the normal work of SPD.the ground contact area is no less than 25 mm2 and as short as possible.
4.the products don't need special maintenance while it is on position for a long time.So we should assign some people to examine regularly.Especially in The thunderstorm season.Once stuck,check it Immediately.
5.The product is equipped with a fault indicator.when working correctly,the indicator shows green,When this system malfunctions,it shows red.
6.The internal components is with alternating current,be careful when the system is working.
