Problems solved by technology

[0005] When the installation position of the drop-out fuse is higher than the ground, the operator below needs to lift the long tool with a hook to operate, but due to the problem of sight distance and the small ring pull ring, it is difficult to see clearly, and it is difficult to extend the hook into the fuse. It is very inconvenient to operate in the ring pull ring

Abstract

The invention discloses a manual operating mechanism for the opening and the closing of a dropout type fuse and a fuse carrier with the manual operating mechanism. The manual operating mechanism comprises a top hook with a downward notch and a drag hook with an upward notch. The fuse carrier comprises a fuse tube, a contact, a fuse carrying sleeve and the manual operating mechanism, wherein the contact is arranged at the top part of the fuse tube, the fuse carrying sleeve is arranged at the lower part of the fuse tube, and the manual operating mechanism is arranged on one side of the fuse tube, is used for opening and closing operation and comprises a top hook with a downward notch and a drag hook with an upward notch. The invention has the advantages of rapid and convenient opening and closing operation.

Description

technical field [0001] The invention belongs to the technical field of fuses, and in particular relates to a manual operating mechanism for opening and closing a drop-out fuse and a fuse-carrying part made by using the manual operating mechanism. Background technique [0002] A fuse is a protective device that protects electrical equipment from over-short circuits. Its working principle is that when the line is short-circuited or overloaded, the melt in the fuse-carrying part of the fuse is melted to form an arc, and the arc is stretched under the action of the elastic mechanism. A high pressure is established in the fuse-carrying part tube, and the free metal gas is ejected out of the tube to extinguish the arc, thereby breaking the short-circuit current. At the same time, the fuse-carrying part falls under the action of its own weight, forming a visible isolation fracture. The development of dropout fuses in China has a history of more than 50 years. In the early days, pr...
