Abstract

Anti-bird shield is a kind of commonly used anti-bird device in overhead transmission lines and is mainly used in the medium-risk and high-risk area of bird-related failure. In view of such problems of the existing structure of the anti-bird shield as inconvenient installation and maintenance as well as easy to fall off in the application

a kind of fitting anti-bird shield which combined ball head hanging ring structure and inner embedded metal shield base is designed with the goal of simplifying the number of parts

eliminating loose structure and using mature raw material

and its influence on the electric field distribution of the composite insulator is simulated and analyzed. The simulation results show that the designed fitting anti-bird shield has a certain electric field shielding effect

can improve the local electric field distribution at the low voltage end of the insulator

and the improvement effect can be improved by increasing the diameter of the metal base. The designed fitting anti-bird shield in actual application operates well and achieves the design purpose.
