According to its voltage, it can be classified into high-tension switchgear and low-tension switchgear. While according to its installation sites, it can be divided into outdoor switchgear and indoor switchgear. Besides, it can also be classified into stationary switchgear and hand-push- switchgear according to its mobility of the breaker. The switchgear is a combination of various high-low tension electric, measuring instruments, electric safeguards and control switches which function as a distinct performance. Generally, switchgear can form a circuit, which could cooperate with other switchgear and realized distinct function. Switchgear possesses versatile advantages. Structurally, the clapboards are used to separate the room in switchgear, which shaped several individual small spaces. Such independent small spaces can depart the high-tension switch, isolating shutters, relay protecting as well as measuring instruments each other, which is in favor of restrictin
