Description

Photovoltaic inverter adjustable magnetic ring box

technical field

The utility model relates to a photovoltaic inverter, in particular to an adjustable magnetic ring box of the photovoltaic inverter.

Background technique

Photovoltaic inverter is an important component of photovoltaic substation, and a magnetic ring is installed in the photovoltaic inverter to filter the current. The magnetic ring is generally installed in the magnetic ring box, and the magnetic ring box is fixed on the power lining board of the photovoltaic inverter. Since the photovoltaic inverter is divided into various models of various power sizes according to the application occasions, each type of The number of required magnetic rings is different, and the size of the magnetic ring box for installing the magnetic ring is also different, so that each type of photovoltaic inverter needs to design the magnetic ring box separately, open the mold and produce it separately, the installation is inconvenient, and the investment and cost of equipment production They are all very high, and the magnetic ring box of the corresponding model must be replaced during maintenance, which is very inconvenient for later maintenance work.

Utility model content

The utility model designs an adjustable magnetic ring box of a photovoltaic inverter aiming at the shortcomings of the above-mentioned prior art.

The adjustable magnetic ring box of the photovoltaic inverter of the utility model includes a box body with upper and lower openings, a first support frame is installed on the upper opening of the box body, and a bottom support is installed in the lower opening.

The side plates on the left and right sides of the box body are provided with a plurality of fixing structures from bottom to top, and the fixing structures include two installation holes arranged at the front and back. The distance between adjacent fixing structures is the same, and the two fixing structures of each fixing structure A heat dissipation grill is arranged between the mounting holes.

The side wall of the bottom support is connected with the box body through bolts installed in the installation holes, and a second support frame is installed on the top of the bottom support.

Preferably, the first support frame and the second support frame have the same size, and both are elastic rubber pads.

The beneficial effect of the utility model is: the photovoltaic inverter can adjust the magnetic ring box to install the magnetic ring in the box body through the installation hole of the fixed structure. Installing multiple sets of magnetic rings from top to bottom improves the adaptability of the structure, meets the various needs of the photovoltaic inverter for the magnetic rings, and reduces the cost of design, manufacturing and maintenance. The bottom bracket can be installed on the adjacent fixed structure, so that it can be installed at various height positions in the box body, support the magnetic ring, and fix the magnetic ring through the first support frame and the second support frame to prevent the photovoltaic inverter from being transported. The vibration in the process shatters the magnetic ring, ensuring the structural integrity of the photovoltaic inverter and avoiding unnecessary losses. Each set of magnetic rings is installed on the corresponding fixed structure. A heat dissipation grill is set between the two mounting holes of the fixed structure, so that each set of magnetic rings has a corresponding ventilation structure, which improves heat dissipation efficiency, ensures stable operation of the equipment, and improves equipment life. . The size of the first support frame is the same as that of the second support frame, so that when the two support the magnetic ring, the position of the magnetic ring will not be deflected, ensuring the stability of its installation, and the two support frames are elastic rubber pads, which can avoid photovoltaic inverse The vibration generated by the reactance during the operation of the transformer is transmitted to the magnetic ring to avoid the vibration of the magnetic ring and prevent it from being damaged due to vibration.

Detailed ways

In order to further understand the structure, characteristics and other purposes of the present utility model, now in conjunction with the attached preferred embodiment, the detailed description is as follows. The described preferred embodiment is only used to illustrate the technical solution of the present utility model, and does not limit the utility model .

The specific embodiment of the utility model is as follows:

As shown in FIG. 1 , the adjustable magnetic ring box of the photovoltaic inverter includes a box body 1 with upper and lower openings, a first support frame 2 is installed on the upper opening of the box body 1 , and a bottom bracket 3 is installed in the lower opening.

The side plates 4 on the left and right sides of the box body 1 are provided with a plurality of fixing structures 5 from bottom to top, and the fixing structures 5 include two installation holes 6 arranged front and back. Each group of magnetic rings is fixed in the box body 1 between the two side plates 4 through the bracket and the two fixing structures 5 at the same height. The first group of magnetic rings is installed in the uppermost part of the box body 1, and the rest of the magnetic rings are installed next to each other downwards. After all the magnetic rings are installed, they are installed in the bottom bracket 3, and the bottom bracket 3 is adjacent to the bottom group of magnetic rings. . Bottom bracket 3 adjusts its installation position according to the number of magnetic rings loaded in the box body 1, so that it can support and fix the magnetic rings.

The side wall of the bottom support 3 is connected with the box body 1 through the bolts 8 installed in the installation holes 6 , and the second supporting frame 9 is installed on the top of the bottom support 3 .

The distance between the adjacent fixing structures 5 is the same, which can prevent the magnetic rings from being squeezed and damaged while ensuring that the magnetic rings can be loaded normally.

A heat dissipation grill 7 is arranged between the two installation holes 6 of each fixed structure 5, so that each set of magnetic rings has a corresponding heat dissipation structure, so as to avoid excessive temperature inside the box, ensure long-term stable operation of the equipment, and improve the service life of the equipment .

The first support frame 2 is the same size as the second support frame 9. Since the magnetic ring is nanocrystalline, it is very fragile. The first support frame 2 and the second support frame 9 support the magnetic ring from the upper and lower parts respectively to avoid the magnetic ring during transportation. In the process of damage due to vibration, the first support frame 2 and the second support frame 9 are elastic rubber pads, which can further eliminate vibration, prevent the vibration of other components of the photovoltaic inverter from being transmitted to the magnetic ring, further avoid damage to the magnetic ring, and ensure the magnetic ring integrity.
