Aiming at the problem that the convective heat transfer coefficient depends on experience in the calculation process of arrester temperature rise, a method of determining convective heat transfer coefficient was proposed. The temperature field distribution inside the arrester was studied. The influences of pollution, wind speed and sunshine on the temperature rise of the arrester at different damp degree and different damp positions were analyzed. The results show that under different influencing factors, the convective heat transfer coefficient of the arrester ranges from 5 to 31, 27 to 35 and 19 to 34 W/(m2·℃), respectively. The pollution location will affect the temperature rise distribution of MOA surface, and the greater the degree of moisture, the more significant the impact on temperature rise. With the increase of wind speed, the temperature on the valve plate decreases slightly. However, the surface temperature decreases greatly. The influence of sunshine on the temperature rise of lightning arrester is obviously increased, but it is smaller than that of pollution and wind speed.

针对避雷器温升计算过程对流换热系数依靠经验确定的问题,提出了对流换热系数计算方法,研究了避雷器内部温度场分布,分析了污秽、风速、日照三种因素对不同受潮程度、不同受潮位置下避雷器温升的影响。结果表明,不同影响因素下,避雷器表面对流换热系数取值范围分别为5~31、27~35、19~34 W/(m2·℃);污秽位置会影响MOA表面温升分布,且受潮程度越大,对温升影响越显著;随着风速的增加,阀片上的温度下降较小,表面的温度下降较大;日照对受潮时的避雷器温升影响明显增大,但较于污秽和风速影响偏小。

针对避雷器温升计算过程对流换热系数依靠经验确定的问题,提出了对流换热系数计算方法,研究了避雷器内部温度场分布,分析了污秽、风速、日照三种因素对不同受潮程度、不同受潮位置下避雷器温升的影响。结果表明,不同影响因素下,避雷器表面对流换热系数取值范围分别为5~31、27~35、19~34 W/(m2·℃);污秽位置会影响MOA表面温升分布,且受潮程度越大,对温升影响越显著;随着风速的增加,阀片上的温度下降较小,表面的温度下降较大;日照对受潮时的避雷器温升影响明显增大,但较于污秽和风速影响偏小。

Aiming at the problem that the convective heat transfer coefficient depends on experience in the calculation process of arrester temperature rise, a method of determining convective heat transfer coefficient was proposed. The temperature field distribution inside the arrester was studied. The influences of pollution, wind speed and sunshine on the temperature rise of the arrester at different damp degree and different damp positions were analyzed. The results show that under different influencing factors, the convective heat transfer coefficient of the arrester ranges from 5 to 31, 27 to 35 and 19 to 34 W/(m2·℃), respectively. The pollution location will affect the temperature rise distribution of MOA surface, and the greater the degree of moisture, the more significant the impact on temperature rise. With the increase of wind speed, the temperature on the valve plate decreases slightly. However, the surface temperature decreases greatly. The influence of sunshine on the temperature rise of lightning arrester is obviously increased, but it is smaller than that of pollution and wind speed.
