Description

断路器脱扣致动装置
技术领域
本发明属于低压电气设备，涉及一种在低压断路器中出现短路电流导致触头斥开时用以触发机构使其动作的断路器脱扣致动装置。
背景技术
在低压断路器工作过程中，当出现短路等故障，致使流过触头的电流超过预设阈值时，动、静触头在电动斥力作用下斥开。断路器脱扣致动装置的作用就是在此过程中及时触发机构，以进行脱扣动作。现有的断路器脱扣致动装置大多存在着结构复杂、改变了模块内部的压力分布、动作可靠性差、反应速度慢等缺陷。
发明内容
本发明所要解决的技术问题是提供一种结构简单、动作可靠、反应迅速的断路器脱扣致动装置。
本发明的断路器脱扣致动装置包括有一个由上盖和下盖对合而成的壳体，有一个致动转臂通过转轴安装在上盖和下盖之间，相应地在上盖和下盖之间设置有供致动转臂安装并在一定角度范围内转动的空间，致动转臂的致动端伸出壳体用来连接常规的机构，致动转臂与壳体的基体之间设置有限制其转动的弹性元件；在壳体上、下盖相对的基体中开有两条气流通道，两个气流通道的进气口分别开在上盖和下盖上，分别用来与断路器相邻两极的灭弧区域相通；两条气流通道的前端开口处均安置有可沿气流通道滑动的活塞，两个活塞与上述的致动转臂为一个整体并可随致动转臂转动。
本发明结构简单、制造和安装方便，其可利用断路器内部发生短路等故障时情况下产生的高气压作为动力直接推动致动转臂动作，动作过程迅速、可靠。
附图说明
图1是本发明第一个实施例的分解结构示意图；
图2是第一个实施例在未动作时去除上盖后的平面结构示意图；
图3是第一个实施例在进行致动动作时去除上盖后的平面结构示意图；
图4是本发明第二个实施例的分解结构示意图；
图5是第二个实施例在未动作时去除上盖后的平面结构示意图；
图6是第二个实施例在进行致动动作时去除上盖后的平面结构示意图。
具体实施方式
如图所示，本发明的壳体1由上盖11和下盖12对合而成，致动转臂2可在上盖与下盖之间转动，致动转臂的致动端21伸出壳体之外，用来连接常规的机构。致动转臂还包括两个与之连为一体的活塞22，两个活塞分别安置在壳体内的两个气流通道13的开口132处并可沿气流通道滑动，活塞受压力的面积与其随致动转臂转动的半径相对应。两个气流通道13互不相通，它们的进气口131分别安置在上盖和下盖上，这样当壳体安装在断路器的两个相邻极之间时，两个气流通道的进气口131可以分别与相邻两极的灭弧区域相通。
致动转臂与壳体之间设置有用来使活塞压向气流通道压入的弹性元件3。在图1～图3所示的实施例中，弹性元件3为一个压缩弹簧；在图4～图6所示的实施例中，弹性元件3为一个扭簧，扭簧的主体套在壳体上的固定轴上，扭簧的弹性臂压在致动转臂背面。此外，弹性元件也可以采用簧片等其他形式。
本发明在使用时安装在断路器的两个相邻极之间，当断路器任何一极发生短路等故障时，断路器内部气压升高，气体由壳体上的进气口进入一条气流通道，当压力超过预设值时就推动活塞向外运动，从而带动致动转臂动作，驱动机构使其脱扣。
