Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage lightning arresters, in particular to a durable high-voltage lightning arrester. Background Art

[0002] Lightning arresters are used to protect electrical equipment from high transient overvoltage hazards and limit the amplitude of the follow-on current. They are widely used in power systems to protect communication lines and equipment. In power systems, lightning arresters are usually connected between cables and the ground. When abnormal voltage appears in the power system, the lightning arrester immediately acts to direct the voltage surge current to the ground, thereby limiting the voltage amplitude to protect the insulation of communication cables and equipment.

[0003] A large number of lightning arresters are usually used in substations, but most of them are fixed directly through the mounting plate and the insulating base, lacking auxiliary support and fixation for the lightning arrester. Some lightning arresters used in substations are often longer in size and will be subjected to greater forces in windy weather, resulting in large-scale shaking. These forces will be concentrated at the connection between the lightning arrester and the mounting plate, which can easily cause damage to the lightning arrester and reduce its service life.

[0004] Therefore, it is necessary to propose a durable high-voltage lightning arrester to solve the above problems. Utility Model Content
