What is on the photovoltaic power station lightning protection and fire prevention technology?

Photovoltaic (pv) but with the advantages of 'high yield, low risk' to the user benefits, many families install power station after careful operations, ensure the service life of power station and income flow. At the same time, in case of a thunderstorm or dry weather, many users consider at home

photovoltaic power generation with the advantages of 'high benefit and low risk' to the user. Many families will carefully after installed power plant operation and maintenance of the power plant, in order to ensure the service life of power station and the maximum benefit. At the same time, the thunderstorm or dry weather, many users consider installation of lightning rod to prevent lightning and fire in the home. Is this really necessary? Or what better way to prevent the fire? Necessary in residential photovoltaic power station installation of lightning rod? Rural household photovoltaic (pv) has two characteristics: most roof is shorter, the roof area is limited. Most roof in rural areas are very short, photovoltaic power station lightning strike probability is very low. In addition, there are many tall towers, poles, trees, etc. In the village. These tall buildings can transfer power station, reduce the possibility of power station lightning strike. In addition, the installation of lightning rod should be from the components more than 5 meters. Most of the roof, especially the sloping roof, area is finite, it is difficult to satisfy. If the distance is not enough, the installation could backfire. Therefore, there is no need to install the lightning rod in the ordinary users of family power station. However, individual users in special circumstances. Plant is located in a thunderstorm, for example, many regions or user housing is relatively high, considering the installation can be combined with the actual situation. That should be paid attention to during the installation process, is that if the plant is more than 5 m, component plant should not be shadows shade, at the same time should ensure the unobstructed channels and grounding resistance meet the requirements. Household photovoltaic power station how to fire? A, 'DC arc breaking' preventive measures 1, strictly implements national design standards, design specifications, to ensure construction quality. 2. Carefully selected pv electrical equipment quality, and from the source to inspect 3, photovoltaic power plant construction and installation, should be regulated to eliminate hidden dangers, cable fire prevention measures, because of the large photovoltaic power plant covers an area of cable distribution, it is impossible to set fixed cable fire extinguishing installation. Therefore, fire protection separation and flame retardant cable can be used for cable channel, as the main measures of dealing with the cable fire. Pipe and cable should be noncombustible material or non-combustible material tight seal, prevent cable fire after each other to spread. Third, strengthen the operation of the photovoltaic power station maintenance operations and maintenance personnel shall have the corresponding professional skills. Earnestly the plant maintenance regularly, resolutely stop disease, extended and overload operation. Must be prepared to safety before maintenance. Disconnect all should disconnect switch, in order to ensure that completely discharge the capacitor and inductor. Wear insulated shoes, a low-voltage insulating gloves, when it is necessary to use insulated tools. After the completion of the work, should eliminate the potential accident in the system. Problems found during the maintenance process should be handled in time, such as line contact undesirable, such as aging, it should be replaced in a timely manner.
