Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 5 , 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, silver, Materials such as 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 cross section of the fuse body 2 gradually increases from one end to the other end. Including several partition clips 5, the clamping positions of several partition clips 5 are provided with slots 51 corresponding to each part of the fuse 2. Disconnect and isolate the conductive medium 4 on both sides. This kind of fuse with adjustable fusing current can be installed according to the re...

Abstract

The invention discloses a fusing current adjustable fuse, which comprises conductive connecting pieces positioned at two ends and a fuse link positioned between the conductive connecting pieces, an insulating elastic sleeve is arranged on the outer side of the fuse link, a conductive medium is filled in the insulating elastic sleeve, and the section of the fuse link is gradually increased from oneend to the other end. The fuse further comprises a plurality of partition clamps, the clamping positions of the partition clamps are provided with grooves matched with all parts of the fuse link in aone-to-one correspondence mode, and the partition pieces are clamped on the periphery of the insulating elastic sleeve to enable one section of the fuse link to be out of contact with the conductivemedium and partition the conductive medium on the two sides of the fuse link. According to the fusing current adjustable fuse, the fusing current of the fuse can be adjusted by adjusting the positionof the elastic partition piece, so that one fuse can be used under various use working conditions.

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 and disconnects the circuit with the heat generated by itself 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 ...
