Description

Technical Field

[0001] The utility model relates to the technical field of electric power lightning protection, in particular to an oxide lightning arrester with a drain wire. Background Art

[0002] The arrester is connected between the cables of the power system and the ground, and in parallel with the protected equipment. Once abnormal high voltage occurs, such as a lightning strike, the arrester uses its internal resistors to direct the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the cables and power equipment.

[0003] The arrester and the cable are usually connected by a drain wire. One end of the drain wire is connected to the connection end of the arrester, and the other end is connected to the cable. With this connection method, the drain wire will be affected by wind at high altitudes and swing. Long-term swinging will cause the connection between the drain wire and the arrester to loosen or even break, thus affecting the normal use of the arrester. To this end, we proposed an oxide arrester with a drain wire. Utility Model Content
