Abstract
The utility model relates to a photovoltaic grid-connected inverter comprising a casing, a radiator, a circuit board and an inductor device. The casing sleeves the radiator. The circuit board is fixedly arranged on the radiator. The inductor device is fixedly arranged on the upper end face of the radiator. The inductor device comprises a shielding box, reactors and a boost inductor, the reactors and the boost inductor are arranged in the shielding box, and the shielding box, the reactors and the boost inductor are potted by heat-conduction potting adhesive. The photovoltaic grid-connected inverter is very convenient to produce and assemble. No sealing rubber strip is needed. The waterproof effect is obvious. Full contact between the inductor box and the smooth surface of the radiator is ensured, heat of the reactors is transferred, and interference of electromagnetic field radiation of the inductor to the outside is shielded. The photovoltaic grid-connected inverter has superior performance.
Description
Technical field
The utility model relates to a kind of photovoltaic combining inverter.
Background technology
In recent years, the research of China's photovoltaic combining inverter and application have obtained development fast, because inversion is in production and use procedure, power boost inductance and filter reactor itself is by the power switch pulse current of upper frequency, the communication system of inverter own and control loop have been caused to serious electromagnetic interference, generated output can cause serious electromagnetic radiation when increase, the useful life of the normal operation to safeguards system and personnel, equipment, significant.
At present, general photovoltaic DC-to-AC converter inductance box is to be all contained in outside casing, seal by waterproof adhesive tape and casing, so just have water-proofing treatment problem, mostly water-proof sealing rubber strip is can agingly cause after rubber high temperature that waterproof sealing does not sternly cause product waterproof bad and cause internal circuit premature corrosion and damage.Sealing rubber strip has seriously intercepted the heat conduction that inductance box produces, and causes inverter temperature rise too high, efficiency hydraulic performance decline, the shortcoming such as power density is not high.Conventional inductance box causes the problems such as production and assembly difficulty at the casing back side in addition.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and the photovoltaic combining inverter of a kind of simple in structure, waterproof, anti-electromagnetic radiation successful is provided.
For achieving the above object, the utility model adopts a kind of photovoltaic combining inverter, comprise casing, radiator, wiring board and inductor, casing is set in the top of radiator, described wiring board is fixedly installed on radiator, described inductor is fixedly installed on radiator upper surface, and inductor comprises shielding box and the reactor and the boost inductance that are arranged in shielding box, and shielding box, reactor and boost inductance are by the embedding of heat conduction casting glue.
The utility model further arranges again, and described inductor adopts screw upside-down mounting to form and be electrically connected in the upper surface of radiator one side and with wiring board.
Reactor and boost inductance are contained in shielding cassette interior and then use the embedding of heat conduction casting glue, and outconnector terminal and wiring board formation is electrically connected from the side, the upside-down mounting of inductance box on radiator,
-1-
After casing and radiator combination, ensure that inductance box is in inverter casing inner and upper.
The production and assembly of this Novel photovoltaic grid-connected inverter are very convenient, and without sealing rubber strip, waterproof effect is obvious, ensure that inductance box fully contacts with radiator shiny surface, conduct the heat of reactor, the electromagnetic field radiation that has simultaneously also shielded inductance itself interference to external world, superior performance.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the stereogram of the utility model embodiment inductor.
Fig. 3 is that the utility model embodiment removes the stereogram after casing.
Embodiment
As described in Fig. 1-3, specific embodiment of the utility model is a kind of photovoltaic combining inverter, tip upside down on the inductance box 2 on radiator 1, two reactors 21 and boost inductance 22 are contained in shielding box 23 inside and then use the embedding of heat conduction casting glue, from inductance box 2 side outconnector terminals, inductance box 2 is combined with the power radiator 1 that serves as casing 3 lower covers, two reactors 21 of inductance box 2 embedding and 6 pieces of screw upside-down mountings of the rear use of boost inductance 22 are on radiator 1, after casing 3 upper covers and radiator 1 combination, ensure that shielding box 23 is in inverter casing 3 inner and upper, be connected with below wiring board 4, the production and assembly of this photovoltaic combining inverter are very convenient, without sealing rubber strip, play good waterproof effect, ensure that inductance box 2 fully contacts with radiator 1 shiny surface, conduct the heat of reactor 21, the electromagnetic field radiation that has simultaneously also shielded inductance itself interference to external world.
