Problems solved by technology

However, the fuse in the prior art is generally a fixed fusing current device, and at the same time, the fuse cannot be adjusted or replaced quickly and intelligently, and it cannot continue to be used once it is destroyed. If the current is over-current and the fuse is blown, the smart device will be stagnant, and some devices may be accidentally disconnected, and a new fuse needs to be replaced in time. Since the fuses are all single, timely replacement cannot be guaranteed, resulting in unnecessary loss
In addition, some power equipment is in the stage of equipment research and development, and the selection of fuse specifications is only in the theoretical stage. Different fuses need to be replaced in the test as a basis, but the current of the fuse is different, and the installation method may be different, resulting in the design of power equipment. heavy

Embodiment 1

[0026] please combine figure 1 and figure 2 As shown, this embodiment discloses a fuse assembly, which includes an automatic fuse replacement, a power system, a detection system, and a control system. The automatic fuse replacement includes a push-pull rod 100 , a metal conductor connector 200 connected to the moving end of the push-pull rod 100 , a rotary connector 300 , several melts 400 mounted on the rotary connector 300 , a housing 500 , and a telescopic rod pusher 600 . The telescopic rod pusher 600 is used to push the telescopic rod 100 to extend or retract. The telescopic rod pusher 600 and the telescopic rod 100 are located in the casing, and the metal conductor connector 200 extends from the front end of the casing 600 . The rotary connector 300 is a conductor, and the rotary connector 300 includes a turntable 310 and a driving device 320 for driving the turntable 310 to rotate. The plurality of melts 400 are installed around the outer edge of the turntable 310 , ...

Embodiment 2

[0033] This embodiment is the control method of the fuse assembly in the above-mentioned first embodiment. In the control method, the push-pull rod 100 is pushed to make the metal conductor connector 200 contact and connect with a melt 400 . When the melt 400 is fused, the push-pull rod 100 is retracted, the turntable 310 of the rotary connector is rotated, the other unfused melt is rotated to the position facing the metal conductor connector 200, and the push-pull rod 100 is pushed to make the metal conductor The connector 200 is in contact with the unfused melt to complete the operation of replacing the melt.

[0034] Another optional way is: push the push-pull rod 100 to make the metal conductor connector 200 contact and connect with a melt 400; the detection system detects the current value passing through the melt 400 in real time and sets a comparison threshold, when the detected current When the value is higher than the comparison threshold, the push-pull rod 100 is con...

Embodiment 3

[0036] The third embodiment provides an automatic replacement fuse, which is an independent automatic replacement fuse in the first embodiment. The independent automatic replacement fuse can be manufactured and used as a product alone, and is controlled manually or automatically. The push-pull of the push-pull rod 100 and the rotation of the rotary connector 300 realize the selection of different fuses. Since the automatic replacement of the fuse in this embodiment is exactly the same as the automatic replacement of the fuse included in the first embodiment, it will not be repeated here.

Abstract

The invention relates to an automatic replacement fuse and a fuse assembly. The fuse assembly includes an automatic replacement fuse, a power system, a detection system, and a control system; There are multiple melts. And if a melt is blown, the rotary connector is rotated to connect an unfused melt to the metal conductor connector, and the melt can be replaced quickly and automatically. The invention also provides a control method of the fuse assembly.

Description

technical field [0001] The invention belongs to the technical field of electronic devices, and specifically relates to a fuse and an assembly including the fuse. Background technique [0002] A fuse is an overcurrent protector. The fuse is mainly composed of melt, melting tube and external filler. When in use, connect the fuse in series with the protected circuit. When the current of the protected circuit exceeds the specified value, and after a certain period of time, the heat generated by the melt itself fuses the fuse and disconnects the circuit, thereby protecting it. effect. A fuse that uses a metal conductor as a melt to break the circuit is connected in series in the circuit. When an overload or short-circuit current passes through the melt, the melt itself will heat up and fuse, thus affecting the power system, various electrical equipment and household appliances. to a certain degree of protection. [0003] With more and more types of electrical equipment, elect...
