HVS 12kV\24kV Indoor HV Vacuum Circuit Breaker AREVA ELECTRIC

主要元器件介绍 /Main components introduction

操作机构：用于驱动极柱进行分合闸操作。操作机构为弹簧储能式操作机构，操作功率小，结构紧凑，可靠性高，维护间隔时间长。阿海珐不断
更新与优化断路器操作机构。机构形式分为：弹簧式、永磁式；弹簧操作机构有双排弹簧式与内外双轴弹簧式；结构形式分为整体式与分合闸模
块分组式；操作机构安装方式分为正装式、侧装式等。
Operating mechanism：Drive closing and opening operation of the poles. The operating mechanism is spring energy storage type. It has
small operation power, compact structure, high reliability and long maintenance interval. AREVA ELECTRIC continuously updates and
optimizes the operating mechanism of circuit breakers. Mechanism type is divided into spring type and permanent magnet type, spring type
operating mechanism has double row spring type and double axle spring type; structure form is divided into integral type and module type;
installation mode of operating mechanism is divided into normal type and side-mounted type.
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.
