Abstract

The invention provides a drop-off type fuse grounding device. By welding a bare metal strip inside a fuse tube supporting frame at the lower end of a main body of a drop-off type fuse, the drop-off type fuse grounding device can directly hang a grounding wire, particularly when a space between the drop-off type fuse and a transformer is relatively narrow.

Description

technical field [0001] The invention relates to the field of electrical equipment protection, in particular to a grounding device for a drop-out fuse. Background technique [0002] As we all know, when maintaining or overhauling high-voltage electrical equipment, the fault or inspection point must be grounded. At present, there is no ideal grounding device between the dropout fuse and the transformer, which brings safety hazards to maintenance or overhaul. Contents of the invention [0003] In order to achieve ideal and convenient grounding between the dropout fuse and the transformer, the present invention provides a grounding device for the dropout fuse. [0004] The present invention is achieved in the following way: a bare metal strip is welded on the inner side of the insurance tube support frame at the lower end of the drop-out fuse body so that it can be directly connected to the grounding wire. [0005] The beneficial effects of the present invention are: simple i...
