摘要：

In recent years, underground pipe gallery has become more and more important. Its Special working environment makes temperature monitoring and control increasingly important. paper applies heat-transfer differential equation to the cable to obtain the similarity criterion of cable temperature distribution. After calculating the electric cabin model with different fire separations, it is found that the temperature distribution of the same ampacity in different fire separations conforms to certain rules. The temperature distribution of different ampacity in the same fire separation is also regular: the ampacity rises. 5%, temperature rises by 7%. As a result, the fitting formulas of the current carrying capacity, the length of the fire separation and the location of the highest temperature were also proposed. (C) 2019 The Authors.
