[0002] In photovoltaic power generation systems, in order to reduce the number of connections between the solar photovoltaic cell array and the inverter, a junction box is often added between the photovoltaic modules and the inverter to facilitate maintenance and improve reliability. The junction box is equipped with a junction busbar, an isolating switch, etc. After the currents in multiple energy storage systems are merged on the junction busbar, they are output to the back-end equipment after passing through the isolating switch.

[0003] The wiring in the existing combiner cabinet is generally carried out by cables, and various devices are connected by cables. On the one hand, the wiring is messy, and on the other hand, it is not convenient to disassemble when a short circuit occurs and maintenance is required.

[0004] Therefore, it is necessary to design a junction box wiring structure that is convenient for subsequent maintenance of the wiring inside the junction box. Utility Model Content

[0007] The conductive members are arranged at intervals to form electrical gaps between adjacent conductive members.

[0008] Furthermore, the electrical gap does not exceed 1.5 mm.

[0009] Furthermore, a plurality of insulating parts are arranged on the inner wall of the combiner cabinet; and

[0010] Each of the insulating parts corresponds to a corresponding conductive part; wherein

[0011] The conductive member is connected to the combiner cabinet via an insulating member to fix the conductive member.

[0012] Furthermore, the combiner cabinet is provided with a plurality of fixing holes;

[0013] Each of the insulating members is connected to a corresponding fixing hole respectively.

[0014] Furthermore, each of the fixing holes is a waist-shaped hole.

[0015] Furthermore, a protective plate is provided inside the combiner cabinet.

[0016] Furthermore, the protective plate is arranged on one side of the conductive member to protect the conductive member.

[0017] Furthermore, the conductive member is made of copper.

[0018] Furthermore, a busbar and an isolating switch are provided inside the combiner cabinet on the other side of the conductive member; the busbar is electrically connected to the isolating switch so that after the current is combined on the busbar, it is output through the isolating switch.

[0019] On the other hand, the present application also provides a combiner cabinet, which adopts the wiring structure of the combiner cabinet as described above.

[0020] The beneficial effect of the utility model is that the utility model replaces the original cables with copper conductive parts, and arranges the direction of the conductive parts to make the wiring neater and easier to maintain later. At the same time, the conductive parts are fixed to the junction cabinet by insulating parts. On the one hand, the shaking of the conductive parts is avoided to ensure that the conductive parts and the side walls of the junction cabinet will not touch each other. On the other hand, by fixing the conductive parts, a safe electrical gap is ensured between two adjacent conductive parts. The fixing holes on the junction cabinet are waist-shaped holes, and the insulating parts are fixed on the waist-shaped holes, thereby reducing the accuracy of the conductive part openings and the processing accuracy requirements of the conductive parts, thereby reducing costs.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The wiring in the existing combiner cabinet is generally carried out by cables, and various devices are connected by cables. On the one hand, the wiring is messy, and on the other hand, it is not convenient to disassemble when a short circuit occurs and maintenance is required.

[0031] Therefore, in some embodiments, a combiner cabinet wiring structure is provided, comprising: a plurality of conductive members 2 arranged on the inner wall of the combiner cabinet 1; wherein the conductive members 2 are arranged at intervals to form an electrical gap between adjacent conductive members 2, and the electrical gap does not exceed 1.5 mm.

[0032] In this embodiment, by arranging the conductive parts at intervals and setting electrical gaps, insulation can be achieved through air while ensuring stable and safe electrical performance, saving installation space. The conductive parts are preferably copper busbars, which replace the original cables and arrange the direction of the copper busbars, making the wiring neater and easier to maintain later.

[0033] In some embodiments, a plurality of insulating members 3 are provided on the inner wall of the combiner cabinet 1; and each of the insulating members 3 corresponds to a corresponding conductive member 2; wherein the conductive member 2 is connected to the combiner cabinet 1 through the insulating member 3 to fix the conductive member 2.

[0034] In this embodiment, a plurality of fixing holes are opened on the combiner cabinet, and the fixing holes are preferably waist-shaped holes. The insulating parts are then fixed on the waist-shaped holes, and the copper busbar only needs to be connected to the insulating parts, thereby reducing the accuracy of the copper busbar hole opening and the processing accuracy requirements of the copper busbar, thereby reducing costs. The conductive parts are fixed on the combiner cabinet through the insulating parts, which prevents the conductive parts from shaking and ensures that the conductive parts do not touch the side walls of the combiner cabinet.

[0035] In some embodiments, a protective plate 4 is provided inside the combiner cabinet 1. The protective plate 4 is provided on one side of the conductive member 2. The conductive member 2 is protected by the protective plate 4 to prevent the combiner cabinet from being hit and causing its internal components to touch the conductive member.

[0036] In some embodiments, a busbar and an isolating switch are provided inside the busbar cabinet 1 on the other side of the conductive member 2 (the busbar and the isolating switch are both prior art and therefore not shown in the figure), and the busbar is electrically connected to the isolating switch so that after the current is converged on the busbar, it is output through the isolating switch.

[0037] In summary, the copper busbar is used to replace the original cable, and the direction of the copper busbar is arranged, so that the wiring is neater and convenient for subsequent maintenance. At the same time, the copper busbar is fixed to the junction box through an insulating member. On the one hand, it avoids the shaking of the copper busbar and ensures that the copper busbar and the side wall of the junction box do not touch each other. On the other hand, by fixing the copper busbar, a safe electrical gap is ensured between two adjacent copper busbars. The fixing hole opened on the junction box is a waist-shaped hole, and the insulating member is fixed on the waist-shaped hole, thereby reducing the accuracy of the copper busbar opening and the processing accuracy requirements of the copper busbar, thereby reducing the cost.

[0038] In the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
