[0021] The preferred embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] according to Figures 1 to 6A modular high and low voltage grid-connected switchgear includes a cabinet. The cabinet adopts a modular structure, which allows for the replacement of damaged parts inside the cabinet without the need for tools, greatly increasing the replacement efficiency.

[0023] The combined structure includes several component units 1 that make up the cabinet, a support structure for placing the component units 1, a connection structure for positioning and connecting the component units 1, and a conductive structure for wiring between the component units. The component units 1 are installed on the support structure. The connection structure is located between two component units 1 connected vertically and between the component units 1 connected vertically and the support structure. The conductive structure is located between two component units 1 connected vertically and between two component units 1 connected horizontally.

[0024] Various components are installed inside the component unit 1. These components are pre-fixed inside the component unit 1. This pre-fixing method eliminates the need for tools during replacement, allowing for complete repairs directly through the connection of the component unit 1 and the connection of the circuit terminals.

[0025] The support structure includes a base 4 and legs 5. Several of the constituent units 1 are installed on the base 4. The legs 5 are located at the bottom of the base 4. The front of the base 4 is provided with a limiting plate 12 for limiting the front cover 2.

The receiving port 8 is located on the left and bottom surfaces of the constituent unit 1, and the inlet port 9 is located on the right and top surfaces of the constituent unit 1. The receiving port 8 is larger than the inlet port 9. Both the receiving port 8 and the inlet port 9 are equipped with a cut dustproof pad 10. The dustproof pad 10 serves to prevent dust when not in use, thereby ensuring the cleanliness of the combined unit.

[0029] The receiving port 8 cooperates with the receiving port 9 for connecting the circuits within the component unit 1.

[0030] A telescopic tube 11 is provided on the outside of the inlet 9. The maximum diameter of the telescopic tube 11 is smaller than the diameter of the receiving port 8.
