1975年以来,我们结合每年电气设备预防性试验、设备迎峰渡夏、和新设备载荷运行,以定期重点检查等形式,采用红外测温仪对电力设备在负荷多变的情况下,进行了32228个接触点的温度测量(见表1),其中发现极严重的缺陷一例,温度竟高达306℃(见表2)。由于应用了红外测温技术,有效地防止了类似恶性故障的发生。从表1可见,由于坚 Since 1975, we combined annual annual preventive test of electrical equipment, equipment Yingtandu summer, and new equipment load operation, regular inspections and other forms, the use of infrared thermometer on the power equipment in the case of load changes, 32228 temperature measurement of the contact point (see Table 1), which found a very serious case of defects, the temperature actually as high as 306 ℃ (see Table 2). As a result of the application of infrared temperature measurement technology, effectively prevent the occurrence of similar malignant failures. Can be seen from Table 1, due to Kennedy
