高电压温度在线监测光电变换触头盒的结构  High voltage temperature online monitoring photoelectric conversion contact box structure
技术领域 Technical field
本发明涉及高电压开关设备的温度在线监测装置，具体说是一种 高电压温度在线监测光电变换触头盒的结构。  The invention relates to a temperature online monitoring device for a high voltage switchgear, in particular to a high voltage temperature on-line monitoring photoelectric conversion contact box structure.
背景技术 Background technique
目前移开式开关设备中动静触头由于制造安装偏差以及在运行 动作过程会因电磨损机械操作和短路电动力引起机械振动等原因，使 接触电阻增加，引起温度升高，加剧接触面氧化导致局部温度过高造 成设备重大事故屡有发生。这种现象已成为开关设备的薄弱环节， 因 此如何既准确又方便地在线监测其真实温度是业内人士关注的课题。  At present, the moving and static contacts in the moving-off switchgear increase the contact resistance due to manufacturing installation deviation and mechanical vibration caused by electrical wear mechanical operation and short-circuit electric power during operation, causing temperature increase and intensifying oxidation of the contact surface. The local temperature is too high, causing major accidents of equipment to occur frequently. This phenomenon has become a weak link in switchgear, so how to accurately and conveniently monitor its real temperature online is a topic of concern to the industry.
现有温度在线监测方式主要有两种类型：红外辐射的非接触式和 采用热敏器件的接触式测温非接触式红外传感器由于受环境湿度大 气压的影响较大，红外辐射受遮挡就无法准确测量，使用有很大局限 性， 而接触式的传感器直接与测温点相接触， 受环境因素干扰小， 可 实现准确、 快速温度检测。  There are two main types of on-line monitoring methods for temperature: non-contact type of infrared radiation and contact type temperature measurement non-contact type infrared sensor using heat-sensitive device.

In the actual measurement, when the hot end is far away from the cold end, the compensation wire is also needed.
采用电阻式传感器直接接触测量，在高电位用有线输送信号，简 单运用空气间隙隔离高低电位，通过红外光电转换传输温度信号是一 个不错的办法，但红外发射接收管外露， 长期使用会落灰尘污秽， 使 得信号传输的可靠性 '逐渐变差， 影响测量值也是一个很难解决的问 题? 另外还必须进行现场专业安装调试。 Direct contact measurement with resistive sensor, wire transmission signal at high potential, simple use of air gap to isolate high and low potential, transmission of temperature signal by infrared photoelectric conversion is a good method, but the infrared emission receiving tube is exposed, long-term use will fall dust and pollution , making the reliability of signal transmission 'gradually worse, affecting the measured value is also a difficult problem to solve . In addition, on-site professional installation and debugging must be carried out.
