Do you know how to prevent the solar photovoltaic power station lightning?

The temperature rising, the pace of the summer a little close, a big wave lightning, heavy rain and hail in the not far away waiting for us! Our pv power station can carry it live? Summer weather is changeable, what are the effects of photovoltaic power station, we should do something as soon as possible

high temperature from day to day, summer footsteps getting closer, a lightning, heavy rain and hail the waves in the not far away waiting for us! Our pv power station can bear? Summer weather is changeable, what is the effect of photovoltaic power station, what we should do to minimize the effects of bad weather? Lightning for rooftop photovoltaic power station, lightning will not only destroy the photovoltaic modules and inverters, paralysis of the entire power grid system. As a result of photovoltaic modules and inverters in make up a large proportion of early investment, once by electric shocks, module of power will be reduced, the total power will be reduced. The inverter may be damaged, increase maintenance costs. It not only affects the economic benefits of power station owners, but also may endanger personal safety power station under the roof. How should we deal with mine hurt? 1, to do a good job of lightning protection. The thunder's influence on the photovoltaic power station was divided into two types, namely 'lightning' and 'induction thunder'. As the name suggests, the direct lightning refers to the direct lightning stroke of photovoltaic power generation systems. Induction lightning refers to when near lightning, lightning strikes the energy generated by photovoltaic power generation system of transmission line and grounding line transmission, to exert far more than rated voltage level of power generation equipment, so as to cause damage to equipment. In response, lightning arrester is usually installed in the junction box and process control system, the induction lightning surge voltage, introduced to cope with, prevent power equipment damage. In addition, the personal computer is equipped with a large capacity capacitor, can stable instability of solar energy. The equipment in the inhibition of surge voltage also plays an important role. At the same time, the porsche centre is equipped with over voltage and over current protection device, this will disconnect the DC circuit, in order to prevent the accident due to lightning. In addition, the cable is usually used in communication, remote monitoring monitor instead of metal cable vulnerable to lightning strikes. 2. Because the controller and the inverter are expensive equipment, secondary power surge protector shall be installed in the controller and the inverter, make its have the function of lightning protection. If the inverter output to some of the more important load device, should also be installed in the output of the inverter a three-stage power surge protector. Installed in the power supply system and electronic system multilevel single-pole double throw, also should consider multistage matching. 3. In the present lightning protection measures, the most common method is the most effective and connect metal parts of the electrical equipment from the earth. Grounding system is made up of four parts, namely the earthing equipment, earthing body, the introduction of line and grounding. A good grounding is the important foundation of successful lightning protection measures.
