Quick hanging type drop-out fuse

Abstract

The invention discloses a quick hanging drop-out fuse which comprises a fuse tube body, a hook and a brass screw and is characterized in that the brass screw is in threaded connection with the bottomof the fuse tube body, the hook is detachably connected with the top of the fuse tube body, and a brass wire is arranged in the fuse tube body in a penetrating manner; the hook comprises a hook body,a boss extending towards another end of the hook body is arranged at one end of the hook body, a threaded hole is formed in the boss, a connecting screw is connected in the threaded hole, a top end ofthe connecting screw extends into the hook body, a top block is fixed to a top end of the connecting screw, and a lifting ring nut is fixed to a bottom end of the connecting screw. The fuse has the advantages that quick hanging is achieved through the hook, and the quick connection of a bypass drainage wire can be achieved through the brass screw; the hook is driven and tightened by the connecting screw and then is clamped by the top block, so that the effects of loosening and untight clamping of the wire during locking are avoided; the brass wire is used to replace an original fuse wire, sothat the opening and closing of the fuse can be manually controlled, and the work is convenient.

Description

technical field [0001] The invention relates to a quick hook-up drop-out fuse. Background technique [0002] With the increasing demand for power supply reliability, the application of smart switches is also increasing. In order to replace the smart switch on the pole without power failure, we are currently using the bypass operation method without power failure to replace the smart switch on the pole. However, it is cumbersome to use the existing bypass equipment to replace the intelligent switch on the pole. It is necessary to use the bypass switch, the insulating drain wire and the fixed cross-arm of the insulating drain wire to build a temporary bypass. After the bypass is connected, the smart switch is disconnected, and the The drainage wires on both sides are disconnected to realize intelligent switch replacement. [0003] The existing bypass live work uses a bypass switch to complete the work, and needs to be equipped with a dedicated bypass drain line. The equipmen...
