Description

Technical Field

[0001] This utility model relates to the field of fuse technology, specifically a novel drop-out fuse. Background Technology

[0002] Drop-out fuses are the most commonly used short-circuit protection switches for 10kV distribution line branches and distribution transformers. Installed on 10kV distribution line branches, drop-out fuses can reduce the scope of power outages. Because they have a clearly visible disconnect point, they function as disconnecting switches, creating a safe working environment for lines and equipment under maintenance. When installed on distribution transformers, they can serve as the main protection for the transformers.

[0003] For example, a novel drop-out fuse disclosed in the authorization announcement number CN222690622U belongs to the field of drop-out fuses. It includes a high-strength insulator, with an upper terminal at the upper end of the high-strength insulator and a lower terminal connected to the lower end of the high-strength insulator. The upper terminal is provided with a connecting buckle, and the lower terminal is connected with a rotating connecting frame.

[0004] Although it achieves the installation structure, the mounting plate is installed on the fixed frame through a rotating seat, which can be rotated and adjusted when needed, improving the overall flexibility of the drop-out fuse. The rotating seat has a slot, which is used in conjunction with the limit rod to adjust the angle of the drop-out fuse at a specific angle and ensure the stability after adjustment. The hexagonal block at the end of the limit rod is connected to the threaded seat through a threaded groove, which can ensure the connection stability of the limit rod and prevent the limit rod from falling off and causing the drop-out fuse to loosen.

[0005] However, this does not solve the problem that existing types of fuses are generally not conducive to the convenient installation of new drop-out fuses, making it difficult to easily adjust the tilt angle of new drop-out fuses, to easily adjust the installation position of new drop-out fuses, and to flexibly adjust the spacing between multiple sets of new drop-out fuses, thus affecting the scope and convenience of installation.

(1) Install the mounting plate to the appropriate position, place the three sets of drop-out fuse bodies on the surface of the connecting block, and manually rotate the mounting bolts to fix the drop-out fuse bodies to the surface of the connecting block for easy installation. When it is necessary to adjust the tilt angle of the three sets of drop-out fuse bodies, manually rotate the two sets of limit bolts to loosen the limit bolts on the tilting frame. Manually push the tilting frame to rotate it around the flip axis. The tilting frame drives the connecting block to rotate through the mounting frame, and the connecting block drives the drop-out fuse bodies to rotate through the mounting bolts for easy adjustment of the tilt position of the drop-out fuse bodies. After adjustment, rotate the two sets of limit bolts in the opposite direction to loosen the limit bolts on the tilting frame. The system allows for easy fixing of the drop-out fuse body. When the position of the drop-out fuse body needs to be adjusted, the fixing bolt is manually rotated to loosen the bolt from the locked position. The drive frame is then manually pushed to rotate around the adjustment shaft. The drive frame drives the tilting frame, mounting frame, connecting block, mounting bolt, and drop-out fuse body to rotate, facilitating convenient adjustment of the drop-out fuse body's installation position. Once the desired position is reached, the fixing bolt is rotated in the opposite direction to loosen the bolt from the locked position. This system enables convenient installation of the new drop-out fuse, facilitates easy adjustment of the tilt angle, and improves the ease of installation and use of the new drop-out fuse. (2) Manually rotate the two sets of second bolts to facilitate the change from the locked state to the loose state of the second bolt on the sliding sleeve. Manually push the support frame, and the sliding sleeve slides on the surface of the support rod to provide sliding support for the support frame. The support frame drives the three sets of drop-out fuse bodies to adjust to the appropriate height. Reversely rotate the second bolt to facilitate the change from the loose state to the locked state of the second bolt on the sliding sleeve. When it is necessary to adjust the installation angle of the drop-out fuse body in multiple stages, manually rotate the first bolt to facilitate the change from the locked state to the loose state of the first bolt on the adjusting arm. Manually rotate the adjusting arm to facilitate the rotation of the adjusting arm around the rotating shaft. The adjusting arm drives the drive frame, mounting frame, connecting block, and drop-out fuse body for convenient multi-angle adjustment. When it is necessary to adjust the distance between the three sets of drop-out fuse bodies, manually... The operator rotates two sets of third bolts to loosen the limit block from its locked state. The operator then manually pushes the limit block, which, supported by the sliding rail, moves the transmission plate. The transmission plate then moves the connecting rod, support arm, adjusting arm, drive frame, mounting frame, connecting block, and drop-out fuse body. Once the drop-out fuse body reaches the appropriate distance, the operator rotates the third bolts in the opposite direction to loosen the limit block from its locked state. This allows for convenient adjustment of the distance between the drop-out fuse bodies, enabling convenient height adjustment, convenient multi-level adjustment of the installation angle, and flexible adjustment of the distance between multiple sets of new drop-out fuses, thus increasing the installation range of the new drop-out fuse.
