背景技术 Background technique
在电网运行中，高压开关长时间大负荷运行、接头松动、触头老化等诸多因素导致接触电阻增大，进而引起触头温度升高，设备温度超过一定限度时，不仅会降低设备强度，影响运行寿命，甚至还会引起设备毁坏，造成重大事故。目前，在国内外，对开关柜测温，可采取的成熟的方法大致有三种：加装传感器，受通道限制，不一定能监测到实际发热点，可能出现漏检；加装透视片，不能实现实时监测；采用实时在线监测，不能实现整个柜内在线测温。 In the operation of the power grid, many factors such as long-term heavy-duty operation of high-voltage switches, loose joints, and aging of contacts lead to an increase in contact resistance, which in turn causes an increase in the temperature of the contacts. When the temperature of the equipment exceeds a certain limit, it will not only reduce the strength of the equipment, but also affect Operating life, and even cause equipment damage, resulting in major accidents. At present, at home and abroad, there are roughly three mature methods that can be adopted to measure the temperature of switch cabinets: adding sensors, which are limited by the channel, may not be able to monitor the actual hot spots, and may miss detection; Realize real-time monitoring; real-time online monitoring cannot realize online temperature measurement in the entire cabinet.

由于被探测物体本身辐射能力不同，表面氧化程度、平整度都会影响其表面辐射能力，为了改变其表面发射率，使得物体表面具有高发射率，并且发射率统一，在其表面涂覆一层能改善物体表面辐射能力弱、不一致等特性的涂覆材料，探测效果更佳。 Since the radiation ability of the object to be detected is different, the degree of surface oxidation and flatness will affect its surface radiation ability. Coating materials that improve the characteristics of weak and inconsistent radiation on the surface of objects have better detection effects.
