[0077] The connection line between the main circuit breaker 6 and the contactor 5 is located on the front side of the first mounting plate 2 .

[0078] The first filter 8 is also a direct-connected electrical device. A second wire outlet hole 205 is provided on the surface of the first mounting plate 2. The connecting wire at the output end of the contactor 5 passes through the gap, comes out through the second wiring hole 205, and is connected to the first filter 8.

[0081] In the above structure, the arrangement of the components is reasonably planned, and the arrangement of the components takes into account the wiring sequence relationship between the components, and also takes into account the volume, aspect ratio and other characteristics of the components themselves. In some specific implementation structures, for example, when the length and width dimensions of the cabinet 1 are clearly limited, the arrangement sequence of the components is not convenient to adjust.

[0082] In order to facilitate wiring, the structure of the device mounting plate can be designed differently without affecting the volume of the cabinet 1.

[0083] The first device mounting board 2 has a structural reference Figure 1 and Figure 2 In this embodiment, a first device mounting board 2 is disposed inside the cabinet 1, and all devices except the transformer are mounted on this device mounting board.

[0084] The second device mounting board 3 has a structural reference Figure 3 and Figure 4 In this embodiment, in addition to the first device mounting board 2, a second device mounting board 3 is also included. Except for the transformer, all devices are mounted on these two device mounting boards.

[0085] The second device mounting plate 3 is installed inside the cabinet 1 at intervals from the first device mounting plate along the height direction of the cabinet 1, and the second mounting plate is located on the side close to the top of the cabinet 1; the first miniature circuit breaker assembly 10, the relay 11, and the second miniature circuit breaker assembly 12 are installed on the first device mounting plate 2, and the output contactor and the terminal block assembly 5 are installed on the second device mounting plate 3. The second filter 9 is also installed on the second device mounting plate 3, and is located on the back of the second device mounting plate 3.

[0086] There are also differences in the structures of the cabinets corresponding to the two implementation structures. If only one first device mounting plate 2 is included, the top of the back of the cabinet is inclined. If the first device mounting plate 2 and the second device mounting plate 3 are included, the top of the back of the cabinet is stepped, which is more convenient for the installation of the second filter 9.

[0087] In this structure, the installation area of ​​the second device mounting board 3 can also be regarded as the middle installation area. The gap between the first device mounting board 2 and the second device mounting board 3 is used for wiring, and the use of two mounting boards facilitates wiring.

[0088] In order to ensure that all devices can be installed and the height of the cabinet 1 is sufficient, and to facilitate the installation of the transformer, in some embodiments of the utility model, a structure of a first device mounting plate 2 is further designed. The first device mounting plate 2 includes a main panel 201, and a first side panel 202 and a second side panel 203 integrally arranged with the main panel 201. The first side panel 202 and the second side panel 203 are spaced apart to form a gap area; the electronic devices in the first side mounting area are arranged and installed upward along the bottom of the first side panel 202, and the electronic devices in the second side mounting area are arranged and installed upward along the bottom of the second side panel 203.

[0089] The first side panel 202 and the second side panel 203 may be of equal width, or may be designed according to the width of the product to which they are adapted to be installed.

[0090] The transformer unit includes an isolation transformer 14 , which is installed in a gap area between the first side panel 202 and the second side panel 203 .

[0091] Furthermore, the isolation transformer 14 can be installed inside the cabinet 1 or outside the cabinet 1 .

[0093] refer to Figure 6 and Figure 7In some embodiments of the utility model, the transformer unit includes a control transformer 15, and the control transformer 15 is arranged on the bottom plate of the cabinet 1. Since the volume of the control transformer 15 is smaller than that of the isolation transformer 14 and occupies less space, the structure of the first device mounting plate 2 can be further designed to adapt to the installation of the isolation transformer 14, and the length of the second side panel 203 can be smaller than the length of the first side panel 202. After the first device mounting plate is installed with the cabinet 1, the first side panel 202 is directly installed with the bottom of the cabinet 1, and there is a gap between the second side panel 203 and the bottom of the cabinet 1, and the control transformer 15 is installed below the second side panel.

[0094] It should be noted that, in order to control the structural properties of the structure, according to the working relationship between the various components, in the above-mentioned implementation structure, the power input connector 4, the contactor 5, and the main circuit breaker 6 are installed on one side of the first side panel 202, the interface panel 7 and the first filter 8 are installed on one side of the second side panel 203, and the second filter 9 can be installed on the first device mounting board 2 or behind the second device mounting board 3 according to the structural requirements of the device mounting board.

[0095] In order to facilitate wiring, wiring holes 102 can be designed at the top, side, bottom, etc. of the cabinet 1 according to wiring requirements, which will not be described in detail.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
