Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage fuses, in particular to a fully enclosed outdoor high-voltage fuse. Background Art

[0002] A high-voltage fuse is a safety electrical component specially designed to protect high-voltage circuits. It is used to protect electrical equipment from damage caused by overload and short-circuit currents. When the high-voltage fuse is working, if the current in the circuit exceeds the specified value, it will generate heat to cause the fuse to melt, thereby disconnecting the circuit to protect the electrical equipment.

[0003] The prior art discloses a patent application number "CN202221102369.X", which is an outdoor high-voltage fuse with good protection effect, including a ceramic insulator. The arrangement of a ceramic insulating tube and a closing pull ring is beneficial to shielding the connection between the end conductive cap and the contact contact, preventing the contact position from being affected by other conductors, thereby improving the protection effect. The ceramic insulating tube extends out of the upper part of the end conductive cap, which can delay the appearance time of the arc when the switch is closed.

[0004] The outdoor high-voltage fuse can only achieve shielding protection. However, in actual use, since most high-voltage fuses are often installed and fixed with bolts, the high-voltage fuse cannot be replaced conveniently. Assembly tools are required to load and unload the high-voltage fuse, which affects the replacement efficiency of the high-voltage fuse. At the same time, the high-voltage fuse is exposed to outdoor use, and the bolts are easily rusted when exposed to water, making it difficult to remove the entire high-voltage fuse, which is inconvenient to use.

[0028] Two elastic clips 19 are connected to the inner side surfaces of the two U-shaped clamp seats 18, and a high-voltage fuse body 20 is clamped inside the four elastic clips 19. Through the setting of the elastic clips 19, the elastic clips 19 can be freely adjusted to clamp the high-voltage fuse. One side of the elastic clips 19 is clamped with a fitting seat 23, and the fitting seat 23 is used to fix the high-voltage fuse body 20. The upper sides of the two elastic clips 19 are clamped with a limiting plug plate 21, and a protrusion 22 is fixedly installed inside the limiting plug plate 21, and the protrusion 22 is used to squeeze the elastic clips 19.

[0029] Both ends of the bidirectional threaded rotating rod 2 pass through the base 1 and extend to both ends of the base 1. Both ends of the bidirectional threaded rotating rod 2 are fixedly connected with fixed hand wheels 3. Two limiting round rods 4 are connected to the inside of the base 1. Through the setting of the limiting round rods 4, the two limiting round rods 4 can limit the moving trajectory of the two mounting top seats 5, so that the two mounting top seats 5 can move back and forth smoothly to adjust the position of the insulator 9, which is convenient to use. Two L-shaped bottom plates 7 are installed on the lower side of the base 1. Two mounting holes 8 are provided inside the two L-shaped bottom plates 7. Through the installation and use of the L-shaped bottom plates 7 and the mounting holes 8, the two can be used to fix the entire base 1 so that the high-voltage fuse can be used outdoors.

[0030] Two telescopic positioning blocks 10 are slidably connected to the inner side surface of the mounting top seat 5 . A connecting spring 11 is connected between the two telescopic positioning blocks 10 and the mounting top seat 5 . The telescopic positioning blocks 10 are used to fix the positioning block 6 .

[0031] One side of the telescopic positioning block 10 passes through the mounting top seat 5 and extends to both ends of the mounting top seat 5 . One side of the telescopic positioning block 10 is fixedly connected with a side plate 15 .

[0032] The upper side of the top seat 5 is rotatably connected with a rotary plate 13 distributed in an array, and a No. 1 rubber round pad 14 is installed on the lower side of the rotary plate 13. Through the setting of the No. 1 rubber round pad 14, the rotary plate 13 at the rotary plate 13 can be squeezed on the top of the positioning block 6 to prevent the positioning block 6 from loosening.

[0035] By placing the high-voltage fuse body 20 between the two U-shaped clamp seats 18, the high-voltage fuse body 20 will be embedded in the elastic clips 19 at the two U-shaped clamp seats 18, which is conducive to allowing the elastic elastic clips 19 to be adaptively clamped and fixed to the outside of the high-voltage fuse body 20, which is used to preliminarily position the entire outdoor high-voltage fuse, and then the fitting seat 23 is clamped to the inside of the two elastic clips 19, so that the two elastic clips 19 can stably limit the high-voltage fuse, and then the two limiting plug plates 21 are inserted into the top of the elastic clips 19 in turn, so that the two fitting seats 23 at the elastic clips 19 can squeeze the elastic clips 19 to ensure the stability of the elastic clips 19 when clamped, so that there is no need to use bolts for installation, and the high-voltage fuse can be easily replaced by using the clamping method, thereby improving the replacement efficiency of the high-voltage fuse;

[0036] By respectively clamping the two positioning blocks 6 into the inside of the two mounting top seats 5, the positioning blocks 6 will drive the insulator 9 to be fixed above the mounting top seat 5, and then the two telescopic positioning blocks 10 equipped with connecting springs 11 can also be fixed to the two ends of the telescopic positioning blocks 10 to limit the insulator 9, and then the No. 1 rubber round pad 14 at the rotating plate 13 and the No. 2 rubber round pad 16 at the movable cross plate 12 can be used to reposition the position of the positioning block 6 to ensure the stability of the insulator 9 during installation, which is convenient to use. Then, the fixed handwheel 3 is turned, and the fixed handwheel 3 drives the two-way threaded rotating rod 2 to rotate, so that the two mounting top seats 5 at the two-way threaded rotating rod 2 can move toward each other or relative to each other, so that the distance between the two insulators 9 can be adjusted to adapt to high-voltage fuse bodies 20 of different specifications and lengths, thereby improving the applicability of fully enclosed outdoor high-voltage fuses.
