[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figures 1 to 4The utility model provides a technical solution: a switch cabinet with a compact structure, including a cabinet body 1, wherein the interior of the cabinet body 1 is provided with an upper chamber 2 and a lower chamber 3 from top to bottom, a circuit breaker body 7 is installed on the left side of the inner wall of the lower chamber 3, and an operating mechanism 8 is provided on one side of the circuit breaker body 7. The operating mechanism 8 is used to actuate the circuit breaker body 7 to complete the opening and closing operations of the circuit breaker body 7. A mutual inductor 10 and a grounding switch 12 are installed on the right side of the inner wall of the lower chamber 3 from top to bottom, a support plate 4 is provided on the left side of the inner wall of the upper chamber 2, and a negative pressure switch 12 is installed on the support plate 4. The load switch 5 is located above the circuit breaker body 7. By staggering the circuit breaker body 7, the grounding switch 12, the mutual inductor 10, and the load switch 5 in sequence on the inner wall of the cabinet 1, the electrical components are rationally distributed and the structure is compact. While complying with relevant standards and specifications and electrical clearance requirements, the volume of the cabinet 1 is minimized as much as possible.
