Safety protection device for photovoltaic power station inverter

Abstract

The invention provides a safety protection device for a photovoltaic power station inverter. The safety protection device comprises an outer shell, a base, an inner shell, a side damping seat, a folded plate, a telescopic rod and a wire passing pipe. The right side of the outer shell is hinged to a right side cover, and the front side of the right side cover is connected with the front of the right side of the outer shell through a lock catch; the base is fixedly connected with the upper portion of the outer shell; the four parts of the folded plate are fixedly connected with the upper surfaceand the lower surface of the interior of the outer shell; one end of the telescopic rod is fixedly connected with the upper surface and the lower surface of the interior of the outer shell, and the other end of the telescopic rod is fixedly connected with the two ends of the corresponding side supporting plate; the side support plates are movably connected to the inner sides of the folded plate;the inner shell is slidably connected into the middle openings of the side supporting plates on the two sides; the anti-vibration performance of the inverter protection shell is improved, the probability that the inverter core assembly is damaged by vibration generated in the carrying process is reduced, the effect of limiting the air flow direction can be achieved through an air drainage cover, heat dissipation is more concentrated, and the heat dissipation effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of electric safety protection devices, and more specifically relates to a safety protection device for inverters in photovoltaic power stations. Background technique [0002] Inverters convert DC power into AC power. It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVDs, VCDs, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In recent years, in order to promote new energy power generation, The construction of photovoltaic power stations is becoming more and more widespread. Since the electric energy generated by photovoltaic panels is direct current, it is not convenient to transmit electric energy. Therefore, installing an inverter can convert the direct current generated by photovoltaic panels into alternating current, whi...
