Abstract
The utility model provides a protective device of a high-power photovoltaic inverter, which has an excellent protective effect and a low cost, and comprises a mounting plate, a radiator and a power device, wherein the power device is embedded in the mounting plate and is provided with a radiating surface and a protective surface which are exposed to the outer part, and the radiator is fixedly arranged on the mounting plate and is contacted with the radiating surface of the power device; and the protective surface of the power device is provided with a protective cover capable of covering the protective surface. The technical scheme can be solved by additionally arranging the protective cover on the exposed protective surface, and the protective cover fully covers the protective cover. If the power device explodes, scattered debris can be completely blocked by the protective cover, so that the harm is controlled in a minimum range, the safety performance is enhanced, and the normal operation of surrounding equipment and the personnel safety are effectively protected.
Description
Technical field
The utility model relates to the protector of the high-power photovoltaic DC-to-AC converter that can play a protective role in the test of high-power photovoltaic DC-to-AC converter unit, debug process.
Background technology
Photovoltaic DC-to-AC converter is a link indispensable in the photovoltaic industry, often needs to use powerful photovoltaic DC-to-AC converter in the reality.And high-power photovoltaic DC-to-AC converter can be blasted when serious because power is crossed conference and had potential safety hazard, especially must experience test and debug phase its early stage, and the danger coefficient maximum of this process.
Summary of the invention
In order to overcome the potential safety hazard of above-mentioned high-power photovoltaic DC-to-AC converter, the utility model provides the protector of a kind of protection effect high-power photovoltaic DC-to-AC converter excellent and with low cost.
The protector of high-power photovoltaic DC-to-AC converter provided by the utility model, comprise mounting panel, radiator and power device, power device is inlaid in the mounting panel, power device has radiating surface and the anti-mask that exposes, radiator is fixedly installed to mounting panel and contacts with the radiating surface of power device, and the anti-mask of power device is provided with the protective cover that it is shrouded.
Owing to have exposed two faces on the power device, wherein one side is a radiating surface, radiating surface is not owing to needed to consider its safety problem by the radiator covering, if another side misoperation then easily blast is splashed, be equivalent to exist a not timing bomb, so need to solve the safety problem of this face of protection, technique scheme solves by install protective cover additional on exposed anti-mask, and protective cover will prevent that mask shrouds fully.If power device blast, then protective cover can block the fragment that it scatters fully, and harm is controlled in the minimum zone, strengthens security performance, effectively protects the normal and personnel's of equipment operation around it personal safety.
Below in conjunction with drawings and Examples the utility model is described in further detail.
