Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, and more specifically to a lightning arrester with a support member. Background Art

[0002] A lightning arrester is an electrical appliance used to protect electrical equipment from the harm of high transient overvoltage during lightning strikes, limit the follow-up current time, and often limit the follow-up current amplitude. A lightning arrester is sometimes also called an overvoltage protector or overvoltage limiter. Lightning arresters are divided into many types, including metal oxide lightning arresters, line-type metal oxide lightning arresters, gapless line-type metal oxide lightning arresters, fully insulated composite jacket metal oxide lightning arresters, removable lightning arresters, etc.

[0003] At present, during the long-term use of a lightning arrester, it will be affected by environmental factors, frequent overvoltage and other factors, and gradually age. Aging will lead to a decline in the insulation performance and discharge performance of the lightning arrester, and ultimately cause the lightning arrester to be damaged. At this time, the lightning arrester needs to be replaced. However, when replacing the lightning arrester, since the mounting base of the lightning arrester is usually fixed to the wire rack by multiple bolts, the staff needs to use tools such as screwdrivers to remove the multiple screws on the base one by one before the lightning arrester can be removed. The same method is required for installation, making the replacement of the lightning arrester rather cumbersome and in need of improvement. Summary of the Utility Model
