For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] At present, in power systems, multiple circuit breakers are usually integrated on the same base to facilitate installation and save installation space. However, the existing base is usually an integrated base, and the installation position of the circuit breaker on the integrated base is fixed, the scalability is poor, and the functional structure is single.
[0031] In order to solve the above technical problems, one aspect of the embodiments of the present application is as follows: Figure 1 and Figure 2 , a circuit breaker wiring module 100 is provided, which is used to be connected to a circuit breaker 200. The circuit breaker wiring module 100 includes: a base 110, a bus bar 120 arranged on the base 110, a phase-changing wiring module 130 and a main control module 140, the bus bar 120 and the main control module 140 are electrically connected to the phase-changing wiring module 130 respectively, and the phase-changing wiring module 130 and the main control module 140 are also used to be electrically connected to the circuit breaker 200 respectively.
[0032] The above-mentioned circuit breaker wiring module 100 has a modular design for the integrated base 110 in the prior art, and the integrated base 110 in the prior art is split into multiple parts, including at least the base 110, the bus 120, the phase-changing wiring module 130 and the main control module 140. The various parts can be freely disassembled and assembled. Therefore, the circuit breaker wiring module 100 has good scalability, can adjust the phase sequence, and has a more diversified functional structure. In addition, when a part of the structure of the circuit breaker wiring module 100 fails, the user can also only replace the faulty part without replacing the entire circuit breaker wiring module 100, which is more cost-saving.
[0033] Optionally, in one possible implementation of the present application, please refer to Figure 3 and Figure 4 The phase-changing wiring module 130 is provided with at least one interface 131 , and the interface 131 is provided with a plug-in terminal 132 , and the plug-in terminal 132 is used to be electrically connected to the busbar 120 .
[0034] The plug-in terminal 132 is electrically connected to the busbar 120 by plugging and unplugging, thereby realizing an electrical connection between the phase-changing wiring module 130 and the busbar 120. The plug-in connection can improve the convenience and efficiency of installing the phase-changing wiring module 130, and can realize a stable electrical connection between the phase-changing wiring module 130 and the busbar 120.
[0035] Optionally, in one possible implementation of the present application, please refer to Figure 5 The busbar 120 is provided with a first busbar 121, a second busbar 122, a third busbar 123 and a fourth busbar 124, and the phase-changing wiring module 130 is provided with at least one of a first interface, a second interface, a third interface and a fourth interface, wherein the plug-in terminal 132 at the first interface is used to electrically connect to the first busbar 121, the plug-in terminal 132 at the second interface is used to electrically connect to the second busbar 122, the plug-in terminal 132 at the third interface is used to electrically connect to the third busbar 123, and the plug-in terminal 132 at the fourth interface is used to electrically connect to the fourth busbar 124.
[0036] When the circuit breaker wiring module 100 needs to be connected to multiple circuit breakers 200 at the same time, according to the different phase sequences that the circuit breakers 200 need to be connected to, it is necessary to match the phase-changing wiring module 130 of the corresponding phase sequence for each circuit breaker 200. The phase-changing wiring module 130 can be a combination of two-phase wiring (live wire and neutral wire) (AN / BN / CN), can be single-phase (A / B / C / N), can be three-phase wiring (ABC), or can be four-phase wiring (ABCN). For example, the circuit breaker 200 connected to the AN phase needs to match the phase-changing wiring module 130 of the AN phase. In order to enable the bus 120 to match the phase-changing wiring modules 130 of different phase sequences at the same time, four-phase busbars are set on the bus 120 at the same time, namely the first busbar 121, the second busbar 122, the third busbar 123 and the fourth busbar 124, and the phase-changing wiring modules 130 of different phase sequences can be plugged and connected with the corresponding busbars. For example, the first busbar 121 corresponds to phase A, the second busbar 122 corresponds to phase B, the third busbar 123 corresponds to phase C, and the fourth busbar 124 corresponds to phase N. Then the AN phase phase switching connection module 130 is plugged in and out of the first busbar 121 and the fourth busbar 124 at the same time.
[0037] Optionally, in one implementable manner of the embodiment of the present application, the first busbar 121 , the second busbar 122 , the third busbar 123 and the fourth busbar 124 extend along the length direction of the busbar 120 , and are spaced apart along the width direction of the busbar 120 .
[0038] Accordingly, when the number of the phase-changing wiring modules 130 is at least two, at least two phase-changing wiring modules 130 are sequentially arranged along the length direction of the busbar 120, and the interfaces 131 on each phase-changing wiring module 130 are sequentially arranged along the width direction of the busbar 120. In this way, the busbar 120 can be electrically connected to more phase-changing wiring modules 130 at the same time.
[0039] Optionally, in one possible implementation of the present application, please refer again to Figure 1 The upper part of the phase-changing wiring module 130 is used to connect with the circuit breaker 200 , and the width of the phase-changing wiring module 130 is equal to the width of the circuit breaker 200 adapted thereto.
[0040] The upper part of the phase-changing wiring module 130 is connected to the circuit breaker 200, which can facilitate the installation of the circuit breaker 200. Preferably, the phase-changing wiring module 130 is plug-in connected to the circuit breaker 200 to improve the installation efficiency and convenience of the circuit breaker 200.
[0041] Furthermore, the lower part of the phase-changing wiring module 130 is connected to the base 110 and the busbar 120, that is, the busbar 120 is fixed on the base 110, and the phase-changing wiring module 130 is connected to the busbar 120 above, and the lower part of the phase-changing wiring module 130 is also fixed to the base 110. In this way, the structural layout of the circuit breaker wiring module 100 can be made more reasonable, and the installation of the phase-changing wiring module 130 can be made more stable.
[0042] The width of the phase-changing wiring module 130 is equal to the width of the circuit breaker 200 adapted thereto, so that the arrangement of the phase-changing wiring module 130 can be more compact, thereby saving space and making the appearance of the circuit breaker wiring module 100 more beautiful.
[0043] Optionally, in one possible implementation of the present application, please refer to Figure 2 The phase-changing wiring module 130 includes at least two first phase-changing wiring modules 133 and at least two second phase-changing wiring modules 134. The positions of the at least two first phase-changing wiring modules 133 and the at least two second phase-changing wiring modules 134 correspond to each other. The circuit breaker 200 is electrically connected to one first phase-changing wiring module 133 and one second phase-changing wiring module 134 at the same time. The first phase-changing wiring module 133 and the second phase-changing wiring module 134 corresponding to each other are respectively located on opposite sides of the main control module 140, so as to be connected to the corresponding main control module 140.

[0045] For example, the first phase-changing connection module 133 is an incoming phase-changing connection module 130, the second phase-changing connection module 134 is an outgoing phase-changing connection module 130, the first busbar area 125 is an incoming busbar area, and the second busbar area 126 is an outgoing busbar area.
[0046] The first bus area 125 and the second bus area 126 may be two areas divided on the same bus bar 120 , or may be located on two bus bars 120 respectively, which is not limited in this embodiment.
[0047] Optionally, in an achievable manner of an embodiment of the present application, a first accommodating groove 135 and a second accommodating groove 136 connected to the first accommodating groove 135 are provided on a side of the phase-changing wiring module 130 away from the base 110, the second accommodating groove 136 is located between the first accommodating groove 135 and the base 110, the main control module 140 is located in the second accommodating groove 136, and the first accommodating groove 135 is used to accommodate the circuit breaker 200.
[0048] Preferably, the width of the second accommodating groove 136 is smaller than the width of the first accommodating groove 135 , so as to form a plane supporting the circuit breaker 200 between the first accommodating groove 135 and the second accommodating groove 136 .
[0049] Optionally, in an achievable manner of the embodiment of the present application, the main control module 140 is located between the phase-changing wiring module 130 and the circuit breaker 200. This arrangement facilitates the main control module 140 to simultaneously collect electrical signals from the circuit breaker 200 and the phase-changing wiring module 130, and control the circuit breaker 200.
[0050] This embodiment further provides a distribution box, comprising a circuit breaker 200 and a circuit breaker wiring module 100 as described above, wherein the circuit breaker 200 is electrically connected to a phase-changing wiring module 130 and a main control module 140 in the circuit breaker wiring module 100 , respectively.
