| The switchgear is designed according to armored metal enclosed switchgear under GB3906-2006. The structure of the switchgear is described in Figure 1: The switchgear is composed of two parts: a fixed cabinet and a withdrawable part (referred to as the handcart), and the shell of the cabinet and the partition board of each functional unit are connected by bolts. The protection level of the switchgear shell is IP4X, and the protection level of the circuit breaker room when the door is opened is IP2X. Switchgear can be equipped with vacuum circuit breaker handcart, can also be equipped with fixed load switch. It has aerial inlet (outlet) line, cable outlet and other functional schemes. The switchgear can be installed in a double cabinet arrangement, that is, installed in back-to-back or face to face double rows. |
