the photovoltaic panel device maintenance, first of all should consider how to ensure the maintenance and technical personnel safety operation. The key is to need to install the device can be broken up into parts, make its power can be individually or as a whole to cut off the equipment. Requirements to ensure that the electrical cabinets ( Electric cabinet is made of quality steel processing components to protect the normal work of the cabinet. 】 In good condition, ventilation, moisture and clean is very important. In extreme conditions need to take specific measures: first, as earlier, electrical cabinets is outdoor device. So they are exposed to the bad weather, high temperature and other environmental factors. So regular testing electric cabinet to ensure the good condition is very important. Second, the photovoltaic device in high pressure ( Up to 1000 v dc) Under operation, voltage close to constitute the insulation voltage of the device device. In the annual solar radiation and high temperature condition, the equipment designed to withstand 1000 v voltage in fact can only bear 1000 v full voltage, compared with the 400 v ac voltage run under the same or similar products, the equipment is almost no safety margin' Safety margin is a measure of the total uncertainty of allowable values, mainly by the uncertainty of measurement value and measurement conditions caused by the uncertainty of measurement of value of two parts. 】 。 Therefore, in order to ensure the safe operation of the photovoltaic device & ndash; — And provide maximum output, electrical cabinets and other equipment must be in good condition.
