The utility model discloses a string
inverter of a
photovoltaic power generation system, which comprises a bottom plate, a connecting column is arranged on the bottom plate, an electric telescopic rod is mounted in the inner wall of the connecting column, an upper top is arranged at the upper end of the electric telescopic rod, and a protective separation net is arranged at the lower end of the upper end. A
locking plate is arranged at the front end of the protective partition net, and an
insect repelling lamp is arranged on the inner wall of the
locking plate. According to the utility model, firstly, the upper top ascends and descends regularly through the electric telescopic rod, so that periodic air circulation is realized, internal heat loss is accelerated, and meanwhile, the problem of
high energy consumption caused by
continuous operation is avoided; secondly, through the
collaborative design of the protective separation net and the
insect repelling lamp, mosquitoes can be physically prevented from entering, the insects can be attracted and repelled through the
light source, and the internal cleanliness of the equipment is doubly guaranteed; and the third group and the fourth group of side plates are connected through self-locking rotating shafts and can be flexibly folded and opened to be parallel to the bottom plate or flush with the connecting columns, so that the maintenance process of internal elements is greatly simplified, and the maintenance cost is reduced.
