一种轻钢龙骨装配式复合墙板的防水性能试验研究

Jianzhu Gangjiegou Jinzhan
本文聚焦一种具有横向企口构造的轻钢龙骨装配式复合墙板，展开防水性能试验研究。首先设计足尺试件，开展风压下淋水试验，参照相关标准采用稳定加压法，模拟不同风荷载与风雨共同作用，运用目测法、化学试纸法观测墙体本身水密性；之后针对不同企口间隙的墙板进行淋水试验，运用目测法、化学试纸法和红外热成像法观测横缝渗漏情况。试验结果显示：该复合墙板水密性能优良，水密性能指标达3 000 Pa，满足相关标准要求；横缝间隙影响墙面渗漏，间隙宜控制在2 mm以下；红外热成像检测法能有效判断墙板拼缝是否渗漏 ...

GIS内触头过热的无线感知系统研制

Gaoya dianqi
为了实现72.5 kV及以上电压GIS内触头温度的无线感知，文中阐述了一套GIS内触头温度无线感知系统的设计思路，并进行了研制。通过功能性试验，验证了本系统的有效性和可行性。最后，建立了252 kV GIS角型隔离开关接触良好和接触不良工况模型，开展了一系列局部过热无线感知试验。试验数据与热电偶测试数据进行了对比，验证了本系统的可信性。试验结果表明：本系统能够实现GIS内部触头温度的无线感知；当接触电阻Rj>250 μΩ，动触头及静触头座的温度上升较快；当Rj达到620 μΩ，负荷电流600 A时，
