Abstract

本实用新型涉及一种高压真空断路器推进机构,其特征在于丝杆架上垂直设有滑杆,滑杆上垂直设有滑块,第一辅助开关和第二辅助开关并排反向设置在滑块和丝杆架之间,第一辅助开关的推杆位于底板外,与丝杆架垂直相对,第二辅助开关的推杆与滑块垂直相对。本实用新型将传统的转角斜推式改为直推式,直推式减少了转换的中间环节,并且,由于辅助开国的推杆受到的式垂直的推力,使得位置开关的切换更加平稳可靠,消除了断裂的隐患,减少了开关的维护。

Description

一种高压真空断路器推进机构
技术领域:
本实用新型涉及高压真空断路器,具体涉及一种高压真空断路器推进机构。
背景技术:
原有的高压真空断路器推进机构的位置转换开关的切换采用转角斜推式结构,见附图1。丝杆的推进与退出带动连接运动,从而带动辅助开关的推杆动作实现辅助开关的切换。由于推杆的运动是经过连杆的连动转换来带动的,受力不垂直,推杆容易出现断裂,无法正常切换,直接影响开关和开关柜的防误联锁性能。
发明内容:
本实用新型的目的在于提供一种能够克服上述缺陷的高压真空断路器推进机构。
为了实现上述目的,本实用新型的技术方案如下:一种高压真空断路器推进机构,包括底板,设于底板上的丝杆,丝杆与丝杆架连接,其特征在于丝杆架上垂直设有滑杆,滑杆上垂直设有滑块,第一辅助开关和第二辅助开关并排反向设置在滑块和丝杆架之间,第一辅助开关的推杆位于底板外,与丝杆架垂直相对,第二辅助开关的推杆与滑块垂直相对。
本实用新型将传统的转角斜推式改为直推式,直推式减少了转换的中间环节,并且,由于辅助开国的推杆受到的式垂直的推力,使得位置开关的切换更加平稳可靠,消除了断裂的隐患,减少了开关的维护。
附图说明:
图1为本实用新型的结构示意图
具体实施方式:
下面结合附图和实施例对本实用新型作详细说明。
一种高压真空断路器推进机构,包括底板5,设于底板5上的丝杆6,丝杆6与丝杆架4连接,其特征在于丝杆架4上垂直设有滑杆7,滑杆7上垂直设有滑块1,第一辅助开关2和第二辅助开关3并排反向设置在滑块1和丝杆架4之间,第一辅助开关2的推杆位于底板5外,与丝杆架4垂直相对,第二辅助开关3的推杆与滑块1垂直相对。
丝杆6在旋转过程中,使得丝杆架4前后移动,由于滑杆7与丝杆架4垂直设置,滑块1与滑杆7垂直设置,因此,滑块7也作前后移动。这样,在试验位置上,丝杆架4推动第一辅助开关2的推杆,在工作位置上,滑块7推动第二辅助开关3的推杆,完成辅助开关的动作全过程。
