【技术实现步骤摘要】
一种变压器储油柜用管式油位计
本技术涉及一种变压器储油柜用配件,具体为一种新型可传输信号的管式油位计。
技术介绍
目前,变压器储油柜均选用指针式油位计显示油位及油位报警,指针式油位计由于结构原因,主要存在以下问题:1、指针式油位计的指针摆动主要是靠内部浮球的齿轮、连杆传动实现的,对油位计加工精度要求较高,且油位计指针指示位置并非储油柜内部油面的真实位置,油位显示不够直观;2、指针式油位计的信号报警是通过指针及内部齿轮的机械运动触发信号开关实现的,机械运动误差和行程开关自身误差都会造成信号开关的误动或拒动,报警误差较大;3、指针式油位计的浮球摆动角度受到限制,通常为120°,无法充分量取储油柜内油位,厂家为满足变压器不同的运行环境,往往采用增大储油柜来预防指针式油位计在极限温度下的误报警,增加了变压器生产的成本;4、指针式油位计的浮球在长途运输过程中容易来回摆动进而损坏连杆或内部齿轮,造成油位计的损坏。
技术实现思路
为解决现有变压器储油柜油位显示的上述问题,本技术提供了一种变压器储油柜用管式油位计,适用于油浸式变压器储油柜油位显示及油位报警用。为实现上述专利技术目的,本技术所采用的技术方案为:一种变压器储油柜用管式油位计,它包括防护罩、油位视窗、密封垫Ⅰ、玻璃管、密封垫Ⅱ、带孔螺栓,螺母,信号开关K1,信号开关K2,接线盒,玻璃管为带有上下横通孔的竖直管,其上下端通过带孔螺栓密封,带孔螺栓与横通孔之间设置有密封垫Ⅰ、带孔螺栓穿过储油柜柜盖并通过螺母连接固定,带孔螺栓与储油柜柜盖之间设置有密封垫Ⅱ,玻璃管上下两端分别设有信号开关K1和信号开关K2,玻璃管下侧设置 ...
