高压开关柜系列
High Voltage Switchgear Series

产品特点 / Features
开关柜结构 GB3906-2006 和 IEC298 中铠装金属封闭开关设备标 Switchgear structure GB3906-2006 and IEC298 in armored metal-enclosed
准而设计，整体由柜体和可抽出部分 ( 手车 ) 两部分级组成。柜体结 switchgear standard design, the overall cabinet and can be extracted from the
portion (handcart) two graded composition. Cabinet structure is assembled
构为组装式，用螺栓栓接组合成型，用金属隔板将开关柜体内部分隔 with bolted combination molding, metal separator separates the circuit breaker
为断路器室、主母线室、电缆室和继电器仪表室。外壳防护等级达到 switch inside the cabinet room, the main bus room, cable room and relay
IP3X，各隔室间防护等级为 IP2X，并且所有金属结构件可靠接地， instrument room. Shell protection grade IP3X, among compartment protection
class IP2X, and reliable grounding all metal structures, between the main
主回路系统的隔室间有独立排气的压力释放通道。 circuit compartment exhaust system with separate pressure release channel.
手车根据用途可分为断路器手车、电压互感器手车、计量手车、隔离 Withdrawable circuit breaker can be divided according to use, voltage
手车等，各类手车的外形尺寸相同，相同用途的手车具有良好的互换 transformer handcart, metrology handcart, isolating handcart and so on, all
kinds of handcarts same dimensions, the same purpose trolley with good
性；手车在柜内有试验 / 隔离位置和工作位置，每一处位置都设有联 interchangeability; Handcart in the cabinet there is the test / disconnected
锁装置以保证手车处于以上两位置时不能随便移动。 position and the working position, every position has interlock device to ensure
that can not be moved when the trolley is more than just two locations.
