Abstract:The application investigation on parallel gap lightning protection device of composite insulators for the 110 kV overhead transmission line used in Dongguan Power Supply Company is present in this article.The lightning performance calculation after the installation of parallel gap device is carried out.The functions of its guiding lightning discharge,transferring power frequency arc,uniforming power frequency electric field are verified by tests.The operation situation of the 110 kV line parallel gap lightning protection of composite insulator is introduced.The results show that the designs of the parallel gap for 110 kV transmission line composite insulators meet the requirements.The parallel gap is in good on-site operation condition,which can be used as the positive complement the existing lightning protection measures,and has broad application prospects.
Keywords:lightning protection  composite insulator  parallel gap device  lightning trip-out rate  electric field distribution  experimental study  operation experiences
