论文部分内容阅读
在1987年第6期《中小型电机》上徐孝寅同志发表了一篇“国内外中小型电机绝缘发展状况”的论文,其中有一段话如下:“我国目前新绝缘材料的温度指数,往往是利用热天平谱图求得的快速评定方法,即热重点斜法td(JB1544—76)和割线法tzg(JB2624—79)。用这种快速方法得到的温度指数,其可信度远低于用常规法取得的。所以很难直接引用这些规范”。笔者认为:徐文关于割线法(CL′)的结论是符合事实的,而关于热重点斜法(TPS)td的可信度问题则不符合实际情况
In 1987 No. 6 “small and medium-sized motor” Comrade Xu Xiaoyin published a “domestic and international small and medium-sized motor insulation development,” one of the passage is as follows: “The current temperature of new insulation materials in our country, is often the use of The rapid assessment method of thermoplasma spectrogram, namely the hot-key oblique method td (JB1544-76) and the secant method tzg (JB2624-79) .The temperature index obtained by this rapid method is far less reliable Made by the conventional method, so it is difficult to directly reference these specifications. ” The author thinks: Xu Wen’s conclusion about the secant method (CL ’) is in line with the fact, and the question of the credibility of the TPS Td is not in line with the actual situation
