Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, in particular to a drop-type lightning arrester. Background Art

[0002] The drop-out arrester is a distribution-type zinc oxide arrester modified and cleverly installed on the drop-out mechanism of the drop-out fuse. This allows the arrester to be easily inspected, repaired, and replaced without power outages, using the insulated switch operating lever. The drop-out (throwable, removable) arrester is a distribution-type zinc oxide arrester modified and cleverly installed on the drop-out mechanism of the drop-out fuse. This allows the arrester to be easily inspected, repaired, and replaced without power outages, using the insulated switch operating lever. This not only ensures smooth circuit operation, but also greatly reduces the workload and time of power maintenance personnel. It is particularly suitable for locations where power outages are not suitable, such as communications, airports, stations, hospitals, and busy commercial areas. Other product performance is the same as that of the distribution-type arrester.
