For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In one aspect of the embodiment of the present application, please refer to Figure 1 , Figure 2 As shown, a wiring module 100 is provided, including a housing 10, and a wiring busbar assembly and a wiring terminal assembly arranged in the housing 10. The wiring module 100 is connected to the circuit breaker 201 through the wiring busbar assembly, and the wiring module 100 is connected to the busbar through the wiring terminal assembly.

[0033] The shell 10 serves as a support for the wiring module 100, and a wiring busbar assembly and a wiring terminal assembly are arranged therein. The wiring busbar assembly is used to connect to the circuit breaker 201, and the wiring terminal assembly is used to connect to the bus. The bus is arranged on the base 200, and the wiring modules 100 are arranged on both sides of the base 200. The main control module can be installed under the circuit breaker 201 to form an integral installation between the wiring modules 100 on both sides.

[0034] The wiring module 100, the circuit breaker 201 and the base 200 are all modularly configured. The wiring module 100, the circuit breaker 201 and the base 200 can be freely disassembled and assembled to meet flexible adaptation requirements. The modules can be expanded according to requirements. The overall scalability is strong, the scope of use is expanded, and it has wide applicability.

[0035] Further, in an optional example, the wiring module 100 forms an L-shaped structure, and along the height direction H of the L-shaped structure, the wiring busbar assembly is located above the wiring terminal assembly.

[0036] In terms of layout, the busbar assembly is located at the upper part of the housing 10 , and the terminal assembly is located at the lower part of the housing 10 .

[0037] Among them, Figure 1 As shown, the terminal assembly includes a terminal 103 and a sampling plate 105, and the terminal 103 and the sampling plate 105 are arranged side by side along the length direction L of the L-shaped structure.

[0038] For the sampling plate 105, the sampling plate 105 is as follows: Figure 1 to Figure 4 As shown, the sampling plate 105 is placed in a plane perpendicular to the length direction L and the height direction H.

[0039] The wiring module 100 is connected to the busbar via a wiring terminal 103 . There is at least one wiring terminal 103 . At least one wiring terminal 103 is slidably connected to the housing 10 to correspond to different phase sequences of the busbar.

[0040] For example, Figure 5 As shown, in the present application, only one connection terminal 103 may be provided, and the connection terminal 103 is a movable terminal 103a.

[0041] For example, Figure 1 to Figure 4 As shown, two connecting terminals 103 are provided in the present application, one of which is a movable terminal 103a, which can slide left and right along the length direction L to different positions to correspond to different phase sequences of the bus, and the other terminal is a fixed terminal 103b.

[0042] For example, a bus is installed on the base 200, and the bus can be divided into an N-phase bus, an A-phase bus, a B-phase bus, and a C-phase bus. By sliding the movable terminal 103a to different positions of the shell 10, the N, A, B, and C-phase bus can be connected respectively, which can be used to adjust the connection phase sequence between the wiring module 100 and the bus.

[0043] For the busbar assembly, the busbar assembly includes a busbar, a first current collector 108 and a second current collector 106 connected to the busbar, the wiring module 100 is connected to the circuit breaker 201 through the busbar, the busbar is also connected to the terminal 103, and the busbar includes at least an L-pole busbar 101;

[0044] The first current collector 108 and the second current collector 106 are connected to the sampling board 105 respectively. The first current collector 108 is used to collect the main loop current, and the second current collector 106 is used to collect the leakage current.

[0045] The main loop current collected by the first current collector 108 and the leakage current collected by the second current collector 106 are both fed back to the sampling board 105; in addition, a circuit board 104 is also arranged below the second current collector 106, and the circuit board 104 is also connected to the sampling board 105 for feeding back the collected voltage. The sampling board 105 is connected to the main control module below the circuit breaker 201 to feed back the above-mentioned collected signal to the main control module for processing or output.

[0046] like Figure 5 As shown, the busbar may be provided with only an L-pole busbar 101, or may be provided with only an N-pole busbar 102; Figure 1 to Figure 4 As shown, the L-pole busbar 101 and the N-pole busbar 102 are arranged at the same time, and the N-pole busbar 102 and the L-pole busbar 101 are arranged side by side along the length direction L of the L-shaped structure.

[0047] In one embodiment, Figure 3 As shown, the first current collector 108 is a shunt, and the second current collector 106 is a zero-sequence transformer. At this time, the zero-sequence transformer and the busbar are arranged left and right along the length direction L, and the busbar and the shunt are arranged up and down along the height direction H.

[0048] For example, Figure 1 , Figure 3 In the figure, the zero-sequence transformer is located above the shell 10 and on the left side of the busbar, and two connecting wires 107 pass through it. The two connecting wires 107 are respectively connected to the L-pole busbar 101 and a terminal 103, and to the N-pole busbar 102 and another terminal 103. When the two connecting wires 107 pass through the zero-sequence transformer, the zero-sequence transformer senses the leakage current signal and feeds it back to the sampling board 105.

[0049] In the present application, the shunt is connected to the N-pole busbar 102 and may also be connected to the L-pole busbar 101 , without specific limitation.

[0050] In another embodiment, Figure 4 As shown, the first current collector 108 is a current transformer, the second current collector 106 is a zero-sequence transformer, the current transformer and the busbar are arranged left and right along the length direction L, and the busbar and the zero-sequence transformer are arranged up and down along the height direction H.

[0051] This is equivalent to replacing the shunt in the above embodiment with a current transformer, which has the same function of collecting the main circuit current.

[0052] Furthermore, in terms of layout, the current transformer is located above the housing 10 and on the left side of the busbar, and the zero-sequence transformer is located below the busbar.

[0053] In this embodiment, the connection method of the connecting wire 107 may not be adopted, and a pin is provided on the connection terminal 103, and the pin passes through the zero-sequence transformer and is connected to the busbar.

[0054] The pins and the wiring terminals 103 are integrally arranged. For example, pins are respectively arranged on the two wiring terminals 103 , and the pins pass through the zero-sequence transformer and are directly connected to the L-pole busbar 101 and the N-pole busbar 102 . One wiring terminal 103 is connected to the L-pole busbar 101 , and the other wiring terminal 103 is connected to the N-pole busbar 102 .

[0055] Through the above-mentioned settings, the wiring module 100 provided in the embodiment of the present application can not only realize the function of adjusting the phase sequence through the sliding setting of the wiring terminal 103 within the width of one module, but also realize the current, voltage, and leakage detection functions. It has complete functions and a compact structure, can be adapted to various circuit breakers 201 and power distribution systems, and has strong versatility.

[0056] A wiring trough is provided in the area inside the housing 10 and between the busbar assembly and the terminal assembly for accommodating the lines between the busbar assembly and the terminal assembly to facilitate wiring; the wiring trough puts the lines together, which plays a certain protective role in the safety and cleanliness of the lines.

[0057] On the other hand, please refer to Figure 6 As shown, an embodiment of the present application also discloses a circuit breaker base, including a base 200, a bus, a circuit breaker 201 and a main control module, and the above-mentioned wiring module 100, the bus, the circuit breaker 201, the main control module and the wiring module 100 are all arranged on the base 200, the circuit breaker 201 is connected to the main control module, and the wiring module 100 is respectively connected to the circuit breaker 201 and the bus.

[0058] There are multiple circuit breakers 201 , wiring modules 100 , and busbars. The wiring modules 100 are arranged in two rows on both sides of the base 200 , and the circuit breakers 201 are arranged side by side between the two rows of wiring modules 100 .

[0059] Furthermore, the base 200 can be installed on a 35 mm standard guide rail to facilitate sliding connection with external devices.

[0060] The circuit breaker base includes the same structure and benefits as the wiring module 100 in the above embodiment. The structure and benefits of the wiring module 100 have been described in detail in the above embodiment, and will not be repeated here.

[0061] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
