Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 3 , a fuse with adjustable fusing current, including conductive connectors 1 at both ends, and a fuse 2 between the conductive connectors 1, the fuse 2 is made of commonly used fuse materials, such as copper, Materials such as silver, zinc, lead, and lead-tin alloy can be used. The outer side of the fuse body 2 is provided with an insulating elastic sleeve 3, and the insulating elastic sleeve 3 is filled with a conductive medium 4. The radius of the fuse body 2 gradually increases from one end to the other end. An elastic partition 5 is arranged on the outer periphery of the elastic sleeve 3 , and the elastic partition 5 separates a section of the fuse 2 from the conductive medium 4 on the outer periphery of the insulating elastic sleeve 3 and isolates the conductive medium 4 on both sides. When this kind of fuse with ...

Abstract

The invention discloses a fuse with adjustable fusing current, which comprises conductive connectors located at both ends, and a fuse body located between the conductive connectors, an insulating elastic sleeve is arranged outside the fuse body, and the insulating elastic sleeve is filled with a conductive medium , the radius of the fuse link gradually increases from one end to the other end, and an elastic partition is arranged on the outer periphery of the elastic sleeve. This kind of fuse with adjustable fusing current can adjust the fusing current of the fuse by adjusting the position of the elastic partition, so that one fuse can be used under various working conditions, and the fusing speed of the fuse when it reaches the fusing current is faster. quick.

Description

technical field [0001] The invention belongs to the technical field of fuses, in particular to a fuse with adjustable fusing current. Background technique [0002] A fuse is an electrical component that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overcurrent protectors, fuses are one of the most commonly used protection devices. [0003] The main functional part of the fuse is the fuse link. Under the premise that the material of the fuse link remains unchanged, the thickness of the fuse link determines the fusing current ...
