Switch cabinet cable tray contact busbar joint fiber temperature measurement
The safe operation of key electrical facilities in the power system is the basic guarantee for the normal operation of the national economy.。Power switch cabinet、Bus cable trays, etc. are power equipment、The most important electrical equipment composition of production equipment。Its dynamic and still contacts、Busbar connector、Cable connectors, etc. are at high voltage for a long time、High current working state,Surface oxidation corrosion、Loose fastening bolts、Factors such as aging of contacts and busbar joints,Contact resistance increases,Contacts and joints rise in temperature to heat up。If you don't control it,If it is light, a power outage will occur,If serious, major safety accidents and economic losses。
High insulation pressure resistance。
All-optical measurement device。该传感器在30cm的爬行距离内可承受超过140kV的工频电压,完全满足开关柜的绝缘耐压要求。
防污能力强。
荧光测温传感器根据电压等级的不同,采用不同耐污性强的硅外套和聚四氟乙烯外套,通过特殊的光纤传输信号,可以确保系统的安全性。
感温材料具有很高的可靠性。
温度传感器的感温物质是只对温度敏感的稀土材料,这种材料的长期稳定性得到充分验证,相关系统已成功应用于设备监测30年以上。
分布式系统结构,稳定性高。
为了真正的分布式系统,可以灵活配置,各测温单元之间相互独立,互不影响,不会因一个环节的影响而导致整个系统的故障,具有良好的鲁棒性,可靠稳定。
正确定位测量点。
感温探针体积小(3mm),可准确定位安装位置。
测温周期小,实时性高。
测温周期小于1秒,可充分保证报警的及时性。
