Problems solved by technology

However, the inverter of this mechanism also has certain defects. In order to achieve a better heat dissipation effect, the inductance box usually needs to use a metal aluminum inductance box, which will increase the cost of the inverter, and in order to be able to use The inductance box has the effect of dustproof and waterproof, which requires a good cooperation between the inductance box and the inverter chassis, which will increase the production cost of the inverter, prolong the assembly time of the inverter, and reduce the production efficiency

Abstract

The invention provides a photovoltaic inverter which comprises a box casing. A radiator is arranged at the bottom of the box casing, and an inductance box is further arranged in the box casing. The inductance box comprises a plastic casing which is provided with at least one cavity, the upper end and the lower end of the cavity are of an opening structure, an inductor is arranged in the cavity, the inductance box is fixed to the radiator, and cooling silica gel is arranged between the inductance box and the radiator. Cooling does not need to be performed through the inductance box, the inductance box can be made of plastics, and the production cost can be effectively reduced. The inductance box of the inverter is arranged in the box casing, so that the inverter is more convenient to assemble, and the production efficiency can be effectively improved. A wiring terminal with the structure can reduce circuit connection risk resulting from the thermal deformation of the terminal, the line connecting quality can be effectively improved, lines can be connected more reliably, electrical connection points in the inverter can be reduced, and the loss is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic inverter used in photovoltaic power generation. Background technique [0002] With the increasing shortage of energy and the aggravation of environmental pollution, clean energy and renewable energy have become the key areas of development in countries around the world. Among them, photovoltaic power generation technology has attracted more and more attention because of its green, environmental protection, and renewable advantages. and welcome. In photovoltaic power generation technology, the inverter used to convert DC power generated by photovoltaic modules into AC power is a key component of the entire photovoltaic power generation technology. [0003] The inductance box used to place the inductance in the inverter is usually placed outside the inverter chassis, which can facilitate heat dissipation. For example, the Chinese utility model patent (pa...
