Description

Technical Field

[0001] The utility model relates to the technical field of drop fuses, and particularly relates to a fuse that is convenient to install. Background Technique

[0002] The drop fuse is the most commonly used short-circuit protection switch for the branch lines of 10 kV distribution lines and distribution transformers. The drop fuse is installed on the branch line of the 10 kV distribution line, which can narrow the power outage range. Because it has an obvious disconnection point and has the function of a disconnecting switch, it creates a safe working environment for the overhaul section of the line and equipment. Installed on the distribution transformer, it can be used as the main protection of the distribution transformer. It has the characteristics of economy, convenient operation, and strong adaptability to outdoor environments. It is widely used in 10 kV distribution lines and the primary side of distribution transformers for protection and equipment switching operations, and has been popularized;

[0003] Traditional fuses have some disadvantages. The drop fuse is generally fixed to the bracket at the use position through bolts. Each time it is installed, workers need to carry tools such as wrenches to carry out the operation. They need to adjust it to a suitable angle according to the installation site environment and install it on the cross arm. The installation angles of each installation site are also different, and the operating environments of the installation sites are also different, resulting in it being difficult for workers to install the drop fuse at a suitable angle at the installation site.

[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] As Figures 1-4 shown, a fuse with convenient installation includes a high-strength insulator 1. A connection mechanism 5 is arranged on the outer side of the high-strength insulator 1. The connection mechanism 5 includes a fixing frame 51 installed on the outer side of the high-strength insulator 1. One end of the fixing frame 51 is fixedly connected with a guiding frame 52. A first threaded component 53 is installed inside the guiding frame 52. A limiting ring 54 is fixedly connected to the outer side of the first threaded component 53 near the upper side of the guiding frame 52. A docking buckle 55 is sleeved on the outer side of the limiting ring 54. One end of the docking buckle 55 is fixedly connected with a limiting buckle 56. The rear end of the limiting buckle 56 is movably connected with a connecting rod 57. A second threaded component 58 is installed inside the connecting rod 57. One end of the connecting rod 57 is fixedly connected with a support member 59. One end of the support member 59 is fixedly connected with a mounting plate 510.

[0021] In this embodiment, a fastening plate 511 is fixedly connected to the front end of the fixing frame 51. A third threaded component 512 is installed inside the fastening plate 511. The lower end of the limiting ring 54 is in contact with the upper end of the guiding frame 52. The second threaded component 58 penetrates through the inside of the limiting buckle 56, and the second threaded component 58 is connected with the limiting buckle 56. The fixing frame 51 and the docking buckle 55 are both in a C shape, and the number of the fastening plates 511 is two groups.

[0022] Specifically, loosen the second threaded component 58 and pull the mounting plate 510, so that the mounting plate 510 drives the connecting rod 57 to rotate around the second threaded component 58 through the support member 59, changing the mounting angle of the mounting plate 510. Then adjust the mounting plate 510 to match the installation site. Then tighten the second threaded component 58 to limit the mounting angle of the mounting plate 510. By loosening the second threaded component 58 and pulling the mounting plate 510, the mounting plate 510 drives the connecting rod 57 to rotate around the second threaded component 58 through the support member 59, changing the mounting angle of the mounting plate 510, which can achieve the purpose of facilitating the adjustment of the mounting angle of the mounting plate 510, and then facilitating the adjustment of the mounting plate 510 to match the installation site, thereby reducing the operation difficulty of workers installing the high-strength insulator 1 on site.

[0023] In this embodiment, an upper locking member 2 is installed at the upper end of the high-strength insulator 1. A fuse tube 3 is installed on the lower side of the upper locking member 2 near one side of the high-strength insulator 1. A lower locking member 4 is installed at the lower end of the high-strength insulator 1. The lower end of the fuse tube 3 is installed on the upper end of the lower locking member 4 near one side of the high-strength insulator 1.

[0024] Specifically, put the fixing bracket 51 on the outside of the high-strength insulator 1 and tighten the third threaded component 512, so that the third threaded component 512 pulls the fixing bracket 51 through the fastening plate 511, and the fixing bracket 51 is stuck on the outside of the high-strength insulator 1, thus completing the preliminary preparation work for installing the high-strength insulator 1.

[0025] Working principle:

[0026] During use, the worker first puts the fixing bracket 51 on the outside of the high-strength insulator 1 and tightens the third threaded component 512, so that the third threaded component 512 pulls the fixing bracket 51 through the fastening plate 511, and the fixing bracket 51 is stuck on the outside of the high-strength insulator 1. Then loosen the second threaded component 58 and pull the mounting plate 510, so that the mounting plate 510 drives the connecting rod 57 to rotate around the second threaded component 58 through the support member 59, changing the mounting angle of the mounting plate 510. Then adjust the mounting plate 510 to be similar to the installation site, and then tighten the second threaded component 58 to limit the mounting angle of the mounting plate 510. Then take the high-strength insulator 1 to the wire line and align the mounting plate 510 with the cross arm. Since the mounting angle of the mounting plate 510 has changed, the height of the mounting plate 510 is adapted to the cross arm, and then use bolts to limit the mounting plate 510 on the cross arm, thus completing the installation of the high-strength insulator 1. By loosening the second threaded component 58 and pulling the mounting plate 510, the mounting plate 510 drives the connecting rod 57 to rotate around the second threaded component 58 through the support member 59, changing the mounting angle of the mounting plate 510, which can achieve the purpose of facilitating the adjustment of the mounting angle of the mounting plate 510, and then facilitating the adjustment of the mounting plate 510 to be similar to the installation site, thereby reducing the operation difficulty of the worker installing the high-strength insulator 1 on site.
