Structural features The
switchgear is designed according to the armored metal-enclosed switchgear in GB3906-91. The whole is composed of a cabinet and a middle-mounted withdrawable part (ie, a handcart). The cabinet is divided into four separate compartments, the enclosure protection level is IP4X, and the protection level of each compartment and circuit breaker room is IP2X when the door is opened. It has overhead incoming and outgoing lines, cable incoming and outgoing lines and other functional schemes, which form a complete set of power distribution system devices after arrangement and combination. The switchgear can be installed, debugged and maintained from the front, so they can be installed back-to-back, in double rows and against the wall, which improves the safety and flexibility of the switchgear and reduces the floor space.
