Abstract
Switchgear was utilized in power distribution system, which usually engaged in power transmission, acceptation and distribution. 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 realizeddistinct 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 restricting the enlargement of short-circuit accident, and convenient to repair and maintain. High-tension switchgear is suitable for not only generating electricity, transmission electricity, distributing electricity,electricity transition in electrical system but also the switch, control and protection in electricity depletion. The high-tension switchgear is a kind of electric equipment with the voltage range from 36 KV to 550KV, which mainly include high-tension cut-out, high-tension isolator switch, earthing switch, high-tension load switch, high-tension auto-registration and sectionalizer,high-tension operating mechanism, high-tension anti-explosion power distribution unit and high-tension switch. What’s more, low-tension switchgear is mainly used in industry such as power station, petroleum, chemical industry, metallurgy, spinning and high-rise buildings which function as electricity transition equipment in transmission and distribution of electricity.

摘要
开关柜用于电力配电系统，一般作为发送、接受、分配电能之用，按电压等级的高低可分为高压开关柜和低压开关柜，按装置地点的不同可分为户外式和户内式两种。按断路器是否能动又可分为固定式和手车式。将各种高低压电气、测量仪表、保护电气和控制开关集中在一个柜子里的装置，并能达到特定性能的柜子称为开关柜。一般一个柜子构成一个回路，可以与别的柜子配合使用，达到某一特定的功能。开关柜有以下优点，从结构来看开关柜内的空间用隔板分隔，成许多独立的小间。使高压开关、隔离刀闸、继电保护和测量仪表都互相分隔开。这样有利于限制短路事故的扩大，也便于检修维护。高压开关柜适用于电力系统发电、输电、配电、电能转换和消耗中起通断、控制、保护等作用。电压等级在36KV到550KV的电气设备。主要包括高压断路器、高压隔离开关、接地开关、高压负荷开关、高压自动重合与分段器，高压操作机构、高压防爆配电装置和高压开关等几大类。低压开关柜用于发电厂、石油、化工、冶金、纺织、高层建筑等行业。作为输电配电等电能转换之用。
