结构特点/Structure features
● 开关柜结构GB3906-2006和IEC298中铠装金属封闭开关设备标准而设计，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IP3X，各隔室间防护等级为IP2X，并
且所有金属结构件可靠接地，主回路系统的隔室间有独立排气的压力释放通道。
● 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锁装置以保证手车处于以上两位置时不能随便移动。
● The metal cald switchgear cabine is designed as GB3906-2006和IEC298 and the complete cabinet consists of cabinet body and withdraw ( handcart)
and .the cabinet is assembled type and connected with botls . Inside the cabinet the circuit breaker compartment, mian busbar compartment, cable
compartment and relay compartment are segregated by metal barrier . The protection grade of case reaches to IP3X and the protection grade of each
compartment is IP 2X . All the metal structure shall earth reliably and the compartment of main circuit system has independent pressure relief channel.
● The handcart , according to it application , can be calssified into circuit breaker handcart, instrument transformer handcart , meti\erign handcart and
isolation handcart .Each type of handcart has same appearance and the handcart with same application has good iterhcnagebility .The handcart has test/
isolation position in the cabinet .Each position has interlock device so to assure the handcart can not move freely at above two positions.
