Metal armored removable switchgear is a type of switchgear. The existing metal armored removable switchgear mainly consists of two parts: a fixed cabinet and a trolley. The circuit breaker trolley is pulled out of the cabinet by a pick-up trolley. During maintenance, only the circuit breaker trolley needs to be replaced, which can shorten the maintenance power outage time.

[0003] Existing application number CN202320772191.8 The utility model discloses an AC armored removable switch cabinet, including a switch cabinet main body and a supporting and stabilizing mechanism, the switch cabinet main body includes a cabinet door rotatably installed on the front surface, and two supporting and stabilizing mechanisms are installed back to back on both sides of the switch cabinet main body, the supporting and stabilizing mechanism includes a stabilizing plate, a countersunk bolt, a mounting bolt and a supporting member, the upper end of the L-shaped stabilizing plate is installed on the side of the switch cabinet main body by a countersunk bolt, the lower end of the stabilizing plate is provided with a mounting bolt, and the side of the upper end of the stabilizing plate is provided with a supporting member; the utility model combines the switch cabinet main body and the supporting and stabilizing mechanism, which not only does not affect the installation and use of the switch cabinet main body, but also can further increase its contact area and stability with the ground, avoid the situation where the internal parts become loose and affect the use due to the impact of external force, and increase the safety and stability of the switch cabinet main body.

[0004] Based on the above, when inspecting the circuit breaker trolley of the existing metal armored removable switch cabinet, the circuit breaker trolley needs to be pulled out of the cabinet. After the circuit breaker trolley is pulled out, moisture and dust in the air will enter the cabinet through the vents on the cabinet partition and circulate in the cabinet, affecting the drying and cleanliness of the switch cabinet. In addition, the vents are prone to blockage if they are not cleaned all year round, affecting the cabinet circulation. In order to increase the utilization of space during installation and use, multiple groups of switch cabinets will be installed in parallel. If the installation spacing is too small, it will affect the heat dissipation of the cabinet. In addition, the contact area between a single group of switch cabinets and the ground is small, making the structural stability low. During the inspection or installation process, external force collision may occur, causing the switch cabinet to shake or topple over and hit adjacent groups of switch cabinets.
