双臂水平伸缩式气动隔离开关的设计

Development and Design of Double Arm Horizontal Telescopic Pneumatic Disconnector

目前隔离开关结构一般分为动侧和静侧,分合闸以动侧静侧往复传动的方式。为解决断口距离大、传动方式受限等问题,研发了一种双臂水平伸缩式气动隔离开关结构和气动传动结构,该气动传动方式已成功应用在国家电网常州电气设备检测中心。首次提出了双臂水平伸缩式结构,并具体介绍了隔离开关结构特点及气动结构原理。

At present,the structure of the disconnector is generally divided into the dynamic side and the static side.The opening and closing is based on the reciprocating drive of the static side of the dynamic side.In order to solve the problems such as the large fracture distance and the limited transmission mode,a double arm horizontal expansion pneumatic isolation switch structure and pneumatic transmission structure are developed.The pneumatic transmission mode has been successfully applied in Changzhou Electrical Equipment Testing Center of the national grid.This paper first proposes a double arm horizontal telescopic structure,and introduces the structure characteristics and pneumatic structure principle of the disconnector.
