| 摘 要： | 在输电线路直流融冰装置中所用避雷器的运行工况不同于交流系统中的避雷器,施加在避雷器上的运行电压是直流、工频和谐波的叠加。在该装置中对各种避雷器的能量吸收能力和保护水平要求各有不同。介绍了直流融冰装置中避雷器的运行特点,针对运行特点开展融冰装置用避雷器的关键技术研究,研制的避雷器已在输电线路融冰工程中得到应用。

| Abstract: | The MOA's operating condition in transmission line direct current(D.C.) ice-melting device is different with that in A.C.system.The operating voltage applied to the arrester is the sum of D.C.,power frequency and harmonics.The requirements of energy absorption and protection level to each kind of surge arrester in the device are different.This paper introduces the operation characteristics of surge arresters in D.C.ice-melting device on which the key technologies are researched.The developed arresters have been applied in the DC ice-melting project of the transmission line. |
