DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0035] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] The combiner box is a wiring device that ensures the orderly connection and convergence function of photovoltaic modules in the photovoltaic power generation system. It is mainly used to converge the power output of multiple photovoltaic panels and transmit it to the inverter through cables.

[0037] Specifically, a certain number of photovoltaic cells of the same specifications are connected in series to form photovoltaic strings, and then several photovoltaic strings are connected in parallel to the combiner box. After the currents are combined in the combiner box, they are used in conjunction with the controller, DC distribution cabinet, photovoltaic inverter, and AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection with the city power grid.

[0038] In photovoltaic power generation systems, combiner boxes ensure orderly connection and convergence of photovoltaic strings, making it easy to cut off the circuit during maintenance and inspection, and reducing the scope of power outages in the event of system failures.

[0039] In addition, in the power system, the combiner box also includes the role of introducing high-voltage DC current into the low-voltage distribution system, converting the three-phase AC from the generator into a single-phase DC power supply, converting the high-voltage AC from the distribution transformer into a low-voltage DC power supply, and converting the low-voltage voltage from the user's equipment into a high-voltage AC power supply. At the same time, the combiner box is also used to collect and distribute the AC power of each branch, monitor and protect the line, realize the selection of electrical main wiring and backup wiring methods, and realize the connection of busbars and cable outlet terminals and the control of circuit breaker opening and closing operations.

[0040] However, in some application scenarios, photovoltaic strings are prone to form circulations between the photovoltaic strings due to factors such as uneven lighting, affecting the power generation efficiency of photovoltaic modules and even accelerating the hot spot effect of photovoltaic modules, thereby reducing the service life of photovoltaic modules.

[0041] Specifically, buildings, trees or other obstructions may block direct sunlight, thereby forming shadows on the surface of photovoltaic strings. These shadows will cause uneven lighting on the surface of photovoltaic panels, making the light intensity in some areas lower than in other areas. In addition, the altitude and azimuth of the sun will change over time, which will affect the incident angle and distribution of light on the photovoltaic panels. Light at different angles shining on the photovoltaic panels may also cause uneven distribution of light intensity. In addition, the installation angle and layout of photovoltaic panels are also important factors affecting the uniformity of lighting. If the installation angle is unreasonable or the layout is too dense, some photovoltaic panels may receive less light, resulting in uneven lighting.

[0042] In addition, in some other application scenarios, PV strings are connected to combiner boxes through underground DC cables. When the underground cables are damaged, the combiner box will send power in the opposite direction to the fault point, which may easily cause the cables of the faulty branch and other adjacent branches to burn, thus expanding the scope of the fault and posing a fire risk.

[0043] Therefore, in the prior art, in order to ensure circuit safety, anti-reverse diodes and fuses are also installed on the photovoltaic string. Specifically, the anti-reverse diodes and fuses are respectively installed on the first mounting seat and the second mounting seat, the first mounting seat and the second mounting seat are electrically connected through a wire, and one of the first mounting seat and the second mounting seat is electrically connected to the photovoltaic string, and the other is electrically connected to the fuse, so as to achieve series connection between the four.

[0044] However, when the existing anti-reverse diode and fuse are connected to the photovoltaic string, the first mounting base and the second mounting base need to be connected in sequence through wires, which is a relatively cumbersome step and affects the installation efficiency.

[0045] Based on this, an embodiment of the present application provides a circuit safety seat, firstly, an anti-reverse diode and a fuse are installed on the mounting piece, and then the mounting piece is installed on the base along the guide groove through the guide piece by holding the handle, and the anti-reverse diode and the fuse are respectively limited to the limiting part by the inner concave surface of the guide piece and the bottom end surface of the base, so that multiple conductive parts contact the conductive end of at least one of the anti-reverse diode and the fuse, so that the anti-reverse diode and the fuse are installed in the limiting part and electrically connected to the conductive parts corresponding to the limiting part. When the photovoltaic string and the combiner box are powered on and used, the circuit safety seat realizes the series connection between the photovoltaic string and the combiner box busbar; the anti-reverse diode and the fuse are installed in the circuit through the circuit safety seat provided by the present application, so as to ensure the circuit safety. At the same time, by installing the base into the circuit in advance, when the anti-reverse diode and the fuse need to be installed, the mounting piece is installed to the base to realize the anti-reverse diode and the fuse corresponding to the limiting parts respectively, so as to realize the installation of the anti-reverse diode and the fuse. The operation is simple and the installation efficiency is guaranteed.

[0046] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Reference Figures 1 to 3 As shown, a circuit safety seat provided in an embodiment of the present application includes a mounting member 100 and a base 200 .

[0048] Among them, the mounting member 100 is used to install the anti-reverse diode 1000 and the fuse 2000; the base 200 includes a base 210 and a conductive member 220 installed on the base 210, and at least three conductive members 220 are provided. Two conductive members 220 are used to electrically connect with the photovoltaic string and the combiner box busbar through the base 210, and a limit portion is formed between two adjacent conductive members 220.

[0049] The mounting member 100 is configured to be mounted on the base 200 so that the anti-reverse diode 1000 and the fuse 2000 are respectively connected to the limiting parts and are electrically connected to the conductive members 220 corresponding to the limiting parts.

[0050] Before the photovoltaic string and the combiner box are powered on, the base 200 is first installed in the circuit, and the anti-reverse diode 1000 and the fuse 2000 are installed on the mounting member 100. Then the mounting member 100 is installed on the base 200, and the anti-reverse diode 1000 and the fuse 2000 are respectively limited at the limiting part, so that the plurality of conductive members 220 contact the conductive end of at least one of the anti-reverse diode 1000 and the fuse 2000, so that the anti-reverse diode 1000 and the fuse 2000 are installed in the limiting part and electrically connected to the conductive member 220 corresponding to the limiting part. When the photovoltaic string and the combiner box are powered on, the anti-reverse diode 1000 and the fuse 2000 are installed in the limiting part. When the box is powered on and used, the circuit safety seat is connected in series with the photovoltaic string and the busbar of the junction box; the anti-reverse diode 1000 and the fuse 2000 are installed in the circuit through the circuit safety seat provided by the present application, thereby ensuring the safety of the circuit. At the same time, by installing the base 200 in the circuit in advance, when the anti-reverse diode 1000 and the fuse 2000 need to be installed, the mounting member 100 is installed to the base 200 to realize the anti-reverse diode 1000 and the fuse 2000 corresponding to the limit parts respectively, so that the installation of the anti-reverse diode 1000 and the fuse 2000 can be realized, the operation is simple, and the installation efficiency is guaranteed.

[0051] Among them, when the photovoltaic strings in the photovoltaic module array are unevenly illuminated, there may be a voltage difference between the photovoltaic strings. The unidirectional conductivity of the anti-reverse diode 1000 prevents the occurrence of circulating current. At the same time, the fuse 2000 can quickly cut off the current when overcurrent or overload is detected in the circuit, thereby further protecting the circuit to prevent the occurrence of faults such as circulating current and hot spot effect in the circuit, ensuring the heating efficiency of the photovoltaic module and extending the service life of the photovoltaic module.

[0052] In addition, the installation of the anti-reverse diode 1000 avoids the current backflow caused by the reverse connection of the positive and negative poles of the photovoltaic module, thereby avoiding the burning of the photovoltaic module. At the same time, when a fault occurs in the string, the anti-reverse diode 1000 can be used as a disconnection point to achieve effective isolation, which not only protects the faulty string, but also provides convenience for maintenance; the installation of the fuse 2000 prevents and protects against potential damage caused by circulating current, hot spot effect, etc. in terms of overload protection and circuit safety isolation.

[0053] Specifically, Figure 1 As shown, four conductive members 220 are provided, wherein every two conductive members 220 correspond to the conductive ends of the anti-reverse diode 1000 and the fuse 2000 respectively, and the two conductive members 220 provided between the anti-reverse diode 1000 and the fuse 2000 are connected.

[0054] In addition, the anti-reverse diode 1000 and the fuse 2000 are installed through the detachable connection between the mounting member 100 and the base 200, which not only facilitates the installation and removal operations, but also facilitates the maintenance and replacement of the anti-reverse diode 1000 and the fuse 2000.

[0055] It should be noted that the anti-reverse diode 1000 and fuse 2000 mentioned in this scheme are introduced as elements for preventing circuit circulation and hot spot effects. All elements connected to the circuit to prevent circuit circulation and hot spot effects are within the protection scope of this application and will not be elaborated here.

[0056] In some embodiments, the base 210 has an input terminal 211 and an output terminal 212, wherein the input terminal 211 is used to electrically connect one of the photovoltaic string and the combiner box busbar, and the output terminal 212 is used to electrically connect the other; the input terminal 211 and the output terminal 212 are respectively electrically connected to a conductive member 220.

[0057] When the mounting member 100 is mounted on the base 200 and powered on, the anti-reverse diode 1000, the fuse 2000, and the conductive member 220 will be electrically connected to the power input terminal 211 and the power output terminal 212 of the mounting member 100, thereby realizing the series connection of the anti-reverse diode 1000 and the fuse 2000. The current flows from the photovoltaic string into the power input terminal 211, then flows through the anti-reverse diode 1000 and the fuse 2000 through the conductive member 220, and finally flows out from the power output terminal 212 to the busbar of the combiner box. In this process, the anti-reverse diode 1000 and the fuse 2000 play a key protective role to ensure the stability and safe transmission of the current.

[0058] Furthermore, the guide members 110 respectively connected to the power input terminal 211 and the power output terminal 212 are respectively the first conductive member 220 and the last conductive member 220 on the base 210, so that after the conductive member 220 respectively connects the anti-reverse diode 1000 and the fuse 2000, the photovoltaic panel string and the junction box busbar are electrically connected through the first conductive member 220 and the last conductive member 220.

[0059] In some embodiments, the circuit safety socket further includes at least two connection groups 300 , which are respectively arranged at the power input end 211 and the power output end 212 , and the connection group 300 includes a connection member 310 and a fixing member 320 .

[0060] The connector 310 is installed on the base 210 and is electrically connected to the conductive member 220 ; the fixing member 320 is detachably connected to the connector 310 , and is suitable for connecting the connector 310 to a photovoltaic string or a combiner box busbar.

[0061] The connection group 300 is an important part of the circuit safety seat for connecting with the external circuit, and is suitable for being designed to conveniently connect the photovoltaic string or the combiner box busbar. During the installation process, the connector 310 is first installed on the base 210, and then the connector 310 is firmly connected to the photovoltaic string or the combiner box busbar using the fixing member 320 to ensure the stability and reliability of the connection.

[0062] Among them, the connector 310 is made of conductive material to ensure smooth flow of current. Furthermore, the design of the connector 310 may include a jack, a terminal block or other forms of electrical connectors to facilitate connection with an external circuit; the fixing member 320 is suitable for ensuring that the connector 310 can be firmly connected to the photovoltaic string or the combiner box busbar. Furthermore, the fixing member 320 may use screws, clamps, crimping terminals or other mechanical connection methods to achieve reliable connection and fixation.

[0063] Furthermore, the base 200 also includes a substrate 230, which is installed on one side of the base 210, and the conductive member 220 is installed on the substrate 230, suitable for the mounting member 100 to abut against the base 210 when the anti-reverse diode 1000 and the fuse 2000 are respectively connected to the limiting parts.

[0064] The substrate 230 is installed on one side of the base 210, providing a stable supporting structure for the conductive member 220. In an example, when the anti-reverse diode 1000 and the fuse 2000 are respectively connected to the limit parts, the mounting member 100 is abutted against the base 210, that is, the anti-reverse diode 1000 and the fuse 2000 are clamped at the gap between the conductive member 220 and the base 210, ensuring that the anti-reverse diode 1000 and the fuse 2000 can be accurately installed in the preset position, improving the stability of the overall structure, and further enhancing the positioning accuracy and stability of the anti-reverse diode 1000 and the fuse 2000, thereby ensuring the normal operation and electrical safety of the circuit safety seat.

[0065] In another example, two adjacent conductive members 220 are respectively connected to the ends of the anti-reverse diode 1000 or the fuse 2000 to achieve position limiting between the base 200. Different examples can be used according to actual installation conditions.

[0066] Furthermore, a surface of the conductive member 220 facing the base 210 is a concave surface, and the concave surfaces on the conductive member 220 corresponding to the anti-reverse diode 1000 and the fuse 2000 are matched with the two respectively.

[0067] The concave surfaces on the conductive member 220 corresponding to the anti-reverse diode 1000 and the fuse 2000 match the two respectively, which means that when these components are connected to the conductive member 220, they can fit tightly in the concave surfaces, ensuring good electrical contact and mechanical stability, thereby improving the reliability of the entire circuit safety seat.

[0068] Furthermore, at least one guide member 110 is provided on the mounting member 100, and at least one guide groove 240 for accommodating the guide member 110 is opened on the base 210, which is suitable for the guide member 110 to be inserted into the guide groove 240 and move along the extension direction of the guide groove 240, so that the mounting member 100 is installed on the base 200.

[0069] The guide member 110 plays a guiding and aligning role to ensure that the mounting member 100 can be accurately installed on the base 210. The two ends of the guide groove 240 are respectively arranged at one end of the base 210 connected to the substrate 230 and the other end away from the substrate 230. In this way, when the mounting member 100 is installed, the mounting member 100 can slide in from the other end and slide toward the substrate 230, that is, the guide member 110, until the guide member 110 contacts the conductive end of at least one of the anti-reverse diode 1000 and the fuse 2000; this design can ensure that the mounting member 100 can smoothly slide to the preset position along the guide groove 240 during the installation process, ensure that the mounting member 100 can be accurately installed on the base 210, and enhance the overall stability.

[0070] In some embodiments, at least one heat dissipation hole 213 is defined on the base 210 .

[0071] The heat dissipation holes 213 are designed to improve the heat dissipation performance of the circuit safety seat, ensuring that even under high load or long-term working conditions, the heat can be effectively dissipated to prevent the device from overheating.

[0072] Furthermore, in some examples, the heat dissipation holes 213 may be opened corresponding to the limiting portions to ensure that the heat generated by the anti-reverse diode 1000 and the fuse 2000 during operation can be effectively dissipated, thereby maintaining the normal operation of the device and extending its service life.

[0073] Furthermore, the base 200 further includes a mounting buckle 250 , which is connected to the base 210 and is suitable for fixing the base 200 to the mounting rail in the combiner box through the mounting buckle 250 .

[0074] The mounting rail is installed in the junction box, providing a basis for installing the circuit safety seat and other components. During the installation process, the base 200 is first placed on the mounting rail, and then the base 200 is firmly fixed to the mounting rail using the mounting clip 250, thereby improving the installation efficiency and ensuring the stability and safety of the base 200.

[0075] In one example, not shown in the figure, first select and install a linear mounting rail on the inner wall of the combiner box, select a suitable mounting clip 250, and fix it to the back of the base 200. The base 200 is mounted on the installed mounting rail through the mounting clip 250, and finally, the base 200 is adjusted to a preset position, and the base 200 and the fixing member 320 are firmly fixed together using screws or other fasteners.

[0076] Furthermore, the installation of the mounting rails allows the circuit safety seats with different photovoltaic strings connected in series to be installed on the mounting rails, making the layout inside the combiner box more neat and orderly.

[0077] Similarly, multiple circuit safety sockets can be electrically connected between the photovoltaic strings and the combiner box busbars, which can be selected according to the actual installation situation.

[0078] In some examples, the mounting member 100 may also be used to mount circuit protection components other than the anti-reverse diode 1000 and the fuse 2000 .

[0079] In some embodiments, the mounting member 100 includes two mounting seats 120 , and the mounting seats 120 are used to mount the anti-reverse diode 1000 and the fuse 2000 , respectively. The mounting seats 120 are detachably connected to the mounting member 100 .

[0080] The setting of the mounting base 120 ensures that each component has its specific position, which is convenient for management and maintenance; at the same time, the mounting base 120 is detachably set on the mounting part 100, which is convenient for regular inspection, replacement or maintenance of the anti-reverse diode 1000 and the fuse 2000. The maintenance personnel can quickly remove the mounting base 120, perform related operations, and then reinstall it, thereby reducing downtime.

[0081] In some examples, a plurality of mounting bases 120 may be provided, and circuit protection elements including the anti-reverse diode 1000 and the fuse 2000 may be installed in the plurality of mounting bases 120 according to actual installation conditions.

[0082] In addition, the mounting member 100 further includes a handle 130, which is disposed at the end of the mounting member 100. The provision of the handle 130 makes the mounting member 100 easy to hold and ensures smooth assembly and disassembly between the mounting member 100 and the base 200.

[0083] Furthermore, the handle 130 may be made of a strong and durable material, such as metal or hard plastic, to ensure its load-bearing capacity and service life.
