Like this, not only can realize the installation outside the operation workman cabinet, reduce operation workman's intensity of labour, can realize the flow operation moreover, raise the efficiency. In order to realize the modular assembly of the switch cabinet, not only how to divide, design and arrange the functional rooms, but also how to assemble the functional rooms together after installation. It should be noted that, for a medium voltage switch cabinet, the volume of each functional chamber is relatively large, and how to combine and fix the functional chambers with relatively large volumes and satisfy the requirements of the switch cabinet after the combination and fixation are completed needs creative labor. The combination switch cabinet is also called 'split cabinet', namely, the modular functional rooms are split together.

The utility model provides a switch cabinet. The switch cabinet comprises a first functional compartment 11 and a second functional compartment 12, the first functional compartment 11 and the second functional compartment 12 being adjacent, and the switch cabinet further comprises at least one guide plate 13.
