Indoor HV Vacuum Circuit Breaker AREVA ELECTRIC

主要元器件介绍 /Main components introduction

底盘车：用于将断路器推进或者移出工作位置。采用优质材料制作，结构强度高，操作顺畅
Chassis：For pushing or removing the circuit breaker from its working position. Made by high quality materials.
航空插头：用于与开关柜的电气控制部分进行连接
Plug connector electric connection between VCB and cubicle.

固封极柱：用于主回路的合闸和分闸操作。断路器主体真空泡部分设置在由环氧树脂采用 APG 工艺浇注而成的固封极柱内，这种结构能有效地防止包括外
力冲击、污秽环境等外部因素对真空灭弧室的影响。断路器主体安装在断路器框架后部，与操动机构连接成一个整体。
Pole：Execute closing and opening operation. The vacuum interrupter of the circuit breaker are located in the sealed pole made of epoxy resin poured
by APG process. This structure can effectively prevent the influence of external factors, such as external force impact and polluted environment, on
the vacuum interrupter. The poles are installed at the rear of the circuit breaker frame, and is connected with the operating mechanism as a whole.
梅花触头：用于与开关柜的静触头进行插拔连接。
Moving contact：To connect with the fixed contact.
触臂：用于梅花触头和固封极柱的上下输出桩头进行连接并承受负载电流。
Contact arm：To connect between moving contact and pole output contact surface.

分合闸过程介绍 /Process of closing and opening
储能 /Spring charge

断路器合闸所需能量由合闸簧储能提供。储能既可由外部电源驱动电机
完成，也可以使用储能手柄手动完成。
分合闸指示 The energy to drive the circuit breaker is provided by charging
CO indicator spring. charge can be accomplished either by spring charge motor or
manually by using spring charge handle.
