Description

Technical Field

[0001] The utility model relates to the technical field of active fuses, in particular to an anti-interference active fuse triggering device. Background Art

[0002] Active fuses generally refer to a device used to prevent circuit overloads. It monitors changes in current and automatically interrupts the circuit when the current exceeds a safe range. This device protects electrical equipment from damage caused by overcurrent, while also preventing dangerous events such as fire. Active fuses are widely used in industrial and domestic electrical systems and are an important device for maintaining circuit safety. If you have specific questions about active fuses, please feel free to ask and I will do my best to help you answer them.

[0003] After searching, the patent number is (CN207602505U). A high-voltage fuse triggering device is arranged between the high-voltage fuse and the micro switch, and is characterized in that it includes an insulating rod, a spring and a connecting piece; the insulating rod is made of a hard material; the connecting piece is fixed on the high-voltage fuse, the insulating rod axially penetrates the connecting piece and can slide between the high-voltage fuse and the micro switch; the spring is sleeved on the insulating rod, and one end of the spring close to the high-voltage fuse is connected to the insulating rod. The high-voltage fuse triggering device disclosed in the utility model uses a hard insulating rod to move horizontally to trigger the micro switch to give an alarm signal. It has a simple structure and a low probability of false triggering. However, when using this structure, it is not convenient to replace the insulating rod, which makes it very limited to use. Therefore, a new structure is now proposed to solve this technical problem. Utility Model Content
