Description
Technical field
The utility model relates to field of photoelectric technology, belongs to a kind of structure of photovoltaic inverter.
Technology status
In the photovoltaic application of solar energy, grid-connected (Grid-tied or Grid-connected) generating is the important development trend that photovoltaic is used, and has become the principal mode of photovoltaic application.Because the plurality of advantages of solar energy power generating, its research and development, industrialization manufacturing technology and market development have become various countries, the world today, particularly the main focus of developed country's keen competition.At present, grid-connected photovoltaic system is very general in the application of Japan, Europe and the U.S., and technology and equipment is ripe relatively.
Core component in the grid-connected photovoltaic system is a photovoltaic network inverter, and it is responsible for the direct current that solar cell produces is converted to and the alternating current of line voltage with frequency, homophase, presents to electrical network, realizes parallel network power generation.The reliability of this inverter, efficient, fail safe, monitoring property, environmental suitability are the key indexs of estimating a grid-connected photovoltaic system performance.
Along with developing rapidly of power electronic technology, control technology and new forms of energy application technology, photovoltaic network inverter develops to high efficiency, high reliability direction.
At present, domestic photovoltaic network inverter has the following disadvantages on internal structure:
1, cools off with air cooling way: because general device operating efficiency when rated power is below 90%, so the heat that transformer and inductance produce is more, must adopt air cooling way to cool off, thereby can't seal by implement device, use so also can't directly carry out outdoor mounted.
2, because the device sealing is poor, so be subjected to the dust of environment and the influence of moist degree easily, the reliability of device work can not be protected;
3, effectively sound insulation of the noise of Chan Shenging produces uncomfortable influence to the user.
The utility model content
The purpose of this utility model provides the hermetic device arrangement of the photovoltaic network inverter of a kind of suitable high efficiency, high reliability.This version can be carried out the heat radiation of system effectively, improves system effectiveness, has good Electro Magnetic Compatibility simultaneously.
The technical solution of the utility model is as follows:
The component arrangement structure of photovoltaic network inverter, include cabinet, be equipped with in the cabinet on power main circuit board, control board, transformer and inductance, the radiator power device is installed, it is characterized in that described cabinet upper end perforate, radiator passes perforate up and is installed on the cabinet, and radiator and cabinet bonding crack are smeared the sealing of high-effective water-proof glue; Main circuit board, transformer and inductance, control board are installed in three zones in the cabinet respectively, and it is installed shielding iron plate each other and isolates.
Described transformer below pad is placed with circular aluminium dish and is installed on the chassis backplane, between transformer and the aluminium dish, evenly be coated with full heat-conducting silicone grease between aluminium dish and the chassis backplane.
Line between main circuit board and the control board adopts single winding displacement to connect.
The utility model has following characteristics:
1, the power main circuit board is positioned over the radiator top, and radiator passes the perforate at cabinet top, stretches out outside the cabinet, becomes the part of cabinet housing, and radiator can reach preferable radiating effect directly to the air heat radiation.
2, adopt shielding iron plate to isolate between power main circuit board, transformer and inductance, the control board, prevented mutual electromagnetic interference effectively, have good effect of heat insulation simultaneously.Make the working temperature of control board below 40 ℃.
3, the line between main circuit board and the control board adopts single winding displacement to connect, and significantly reduces wiring quantity on the one hand, reduces the interference between line on the other hand, particularly the interference between the drive signal of IPM modular power device.
4, in order to carry out the heat radiation of transformer better, pad is put circular aluminium dish and is dispelled the heat below transformer.Between transformer and the aluminium dish, aluminium dish and cabinet equally evenly be coated with full heat-conducting silicone grease between the bottom.After using this kind frame mode,, make the radiating effect of this mode directly dispel the heat raising more than 20% than transformer owing to increased area of dissipation and radiating efficiency.
5, cabinet adopts the mode of sealing fully, and output adopts the waterproof terminal to draw.Degree of protection reaches IP65, can prevent from well to drench with rain.Be fit to directly be installed on outdoor.This version can also be prevented dust effectively and is moistureproof, has improved the device reliability of operation greatly.
6, cabinet adopts stainless steel material to make cabinet, effectively prevents to get rusty.
The utility model adopts a kind of brand-new version, bond material and technology have realized the natural cooling working method of photovoltaic network inverter, this version can be carried out the heat radiation of system effectively, improves system effectiveness, has good Electro Magnetic Compatibility simultaneously.The sound insulation of can also preventing dust effectively of this version improves the operational reliability of device.
