[0027] The present application is provided with the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize various changes and modifications to the various embodiments described herein without departing from the scope and spirit of the present application.

[0028] In the description of the present application, the orientation description, such as the orientation or position relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0029] It should be understood that when one element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

[0030] The embodiment of the present application provides an insulation structure for a solar inverter, as shown in Figures 1-7 The insulation structure comprises:

[0031] The inverter box 100 is provided with a partition plate 110 inside the inverter box 100, the partition plate 110 divides the inverter box 100 into an inverter assembly part 120 and an extension part 130, and the inverter assembly part 120 is provided with a solar inverter assembly 140;

[0032] The copper bar structure 200 is connected to the solar inverter assembly 140 in the inverter assembly part 120 at one end and extends into the extension part 130 at the other end;

[0033] The insulation assembly 300 comprises a first insulation component 310 for separating the copper bar structure 200 and the inverter box 100, a second insulation component 320 sleeved on the copper bar structure 200, and a third insulation component 330 for fixing the copper bar structure 200.

[0034] The inverter box 100 is the housing of the entire device, used to accommodate and protect the internal components. Inside the box, there is a partition plate 110 that divides the box into an inverter assembly part 120 and an extension part 130. The inverter assembly part 120 is located inside the inverter box 100 and is where the solar inverter assembly 140 is installed. The extension part 130 is also located inside the inverter box 100 but is separate from the inverter assembly part 120. One end of the copper bar structure 200 is connected to the solar inverter assembly 140 inside the inverter assembly part 120, and the other end extends into the extension part 130 and connects to other components inside the extension part 130. The copper bar structure 200 allows wiring to be done in the extension part 130, avoiding direct wiring on the solar inverter assembly 140, which can cause wiring errors. The first insulation component 310 is used to separate the copper bar structure 200 from the inverter box 100, preventing electrical connection between the copper bar structure 200 and the box. The second insulation component 320 is fitted on the copper bar structure 200, further isolating the electrical connection between the copper bar structure 200 and other components. The third insulation component 330 is used to fix the copper bar structure 200, ensuring its stability inside the inverter box 100.

[0035] The working principle of the utility model is as follows:

[0036] First, one end of the copper bar structure 200 is connected to the solar inverter assembly 140 inside the inverter assembly part 120, and the other end is placed in the extension part 130. The second insulation component 320 is fitted on the copper bar structure 200, and the first insulation component 310 is installed between the copper bar structure 200 and other components. The third insulation component 330 is used to fix the copper bar structure 200, ensuring its stability inside the inverter box 100.

[0037] This insulation structure can effectively isolate the electrical connection between the copper bar structure 200 and other components, improving the safety and stability of the solar inverter. At the same time, this structure can also improve the efficiency and reliability of the solar inverter, prolonging its service life. This insulation structure is suitable for various types of solar inverters, especially those that require high safety and stability.

[0038] In some embodiments, the first insulation component 310 is a rectangular insulation pad extending from the inverter assembly part 120 to the extension part 130.

[0039] The rectangular insulation pad can be made of insulating materials including polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), silicone rubber, etc. These materials have good electrical insulation properties, heat resistance, and chemical corrosion resistance. The design of the rectangular insulation pad is simple, easy to manufacture and install, and also meets the insulation requirements. The rectangular insulation pad can effectively isolate the copper bar structure 200 from the inverter box 100, preventing current leakage and short circuit, improving the safety and reliability of the system.

[0040] In some embodiments, the extension 130 is provided with a first fixing member 150, and the third insulation component 330 is provided with a first fixing structure 340 that cooperates with the first fixing member 150.

[0041] The first fixing member 150 inside the extension 130 can be a metal plate, a plastic bracket, or other suitable structure, which serves to provide a fixing point to fix the third insulation component 330 on the extension 130. The first fixing structure 340 is provided on the third insulation component 330. The first fixing structure 340 can be a metal buckle, a plastic buckle, or other suitable structure, which serves to cooperate with the first fixing member 150 to ensure that the third insulation component 330 can be firmly fixed on the extension 130. The fixing method of the first fixing member 150 and the first fixing structure 340 includes screw fixing, buckle fixing, glue bonding, etc. The fixing method should be able to provide sufficient fastening force to prevent the third insulation component 330 from shifting or loosening during operation.

[0042] Further, the third insulation component 330 is provided with an avoidance slot 350 for avoiding the copper bar structure 200.

[0043] The avoidance slot 350 is designed on the third insulation component 330, which matches the structure of the copper bar in shape and size. The avoidance slot 350 can be a rectangular, circular, or other suitable slot that matches the shape of the copper bar to ensure that the copper bar can pass through smoothly without interfering with other components.

[0044] In some embodiments, the first fixing member 150 is a threaded stud, and the first fixing structure 340 is a through hole. In this embodiment, the first fixing member 150 and the first fixing structure 340 are bolted.

[0045] In some embodiments, the copper bar structure 200 includes a wiring portion 210 and a transition portion 220 for passing through the partition plate 110.

[0046] The wiring portion 210 is the place in the copper bar structure 200 for connecting cables or solar inverter components 140. It usually has one or more holes so that cables or devices can be inserted and connected to the copper bar. The shape and size of the wiring portion 210 are determined according to the needs of specific applications and can be circular, square, rectangular, etc. The transition portion 220 is the part of the copper bar structure 200 for passing through the partition plate 110. It usually has one or more curved or bent parts so that the copper bar can pass through the partition plate 110 smoothly without being hindered. The shape and size of the transition portion 220 are determined according to the thickness and shape of the partition plate 110 and can be linear, arc-shaped, or polygonal, etc.

[0047] Further, the cross section of the wiring portion 210 and the transition portion 220 is in the shape of a concave character.

[0048] The cross section in the shape of a concave character refers to the cross section of the copper bar being concave, i.e. the middle part is concave and the two side parts are convex. When the copper bar is installed, the concave part of the copper bar can be closer to the inverter box 100, avoiding the copper bar from contacting other components. At the same time, as shown in the drawings, the concave part can be used to install other components such as the fan 10, improving the utilization of space. Figure 3

[0049] In some embodiments, the extension portion 130 is provided with a wire inlet 160, and the position of the wire inlet 160 matches the position of the wiring portion 210 located in the extension portion 130.

[0050] The position of the wiring portion 210 matches the position of the wire inlet 160, so that after the wire is inserted into the wire inlet 160, it can be directly connected with the wiring portion 210 without the need for further adjustment of the position, improving the efficiency of wiring.

[0051] In some embodiments, the partition plate 110 has a through slot 170 for the copper bar structure 200 and the insulating assembly 300 to pass through.

[0052] The through slot 170 is a slot-like structure in the partition plate 110 for the copper bar structure 200 and the insulating assembly 300 to pass through, so that the copper bar and the insulating assembly 300 can smoothly pass through the partition plate 110 without being hindered.

[0053] In some embodiments, the second insulating component 320 is an insulating rubber sleeve.

[0054] The insulating rubber sleeve is a sleeve-like structure made of insulating material, which is used to wrap the copper bar structure 200 or the insulating assembly 300 to prevent electrical short circuit and interference. It has excellent insulating performance and mechanical strength, and can withstand certain pressure and temperature.
