Problems solved by technology

The existing fuse has a single function and does not have the filtering function to eliminate the interference signal and noise existing in the power supply
At the same time, the metal wire of the existing fuse is made of lead-antimony alloy, which is a conductive material with high internal resistance. The high internal resistance metal wire will increase the internal resistance of the power circuit, which will affect sensitive audio-visual equipment or precision models. The overall performance of the instrument is affected

Abstract

The present invention discloses a fuse tube with the function of wave filtration, and the fuse tube includes a metal wire and a tube; wherein, the metal wire is arranged in the tube which is filled with granular electric wave absorption materials. The granular size of the electric wave absorption materials stands at 50 items to 300 items. The advantage is that the tube is filled with granular electric wave absorption materials that can well absorb or isolate the interference of miscellaneous waves, at the same time, reduce and restrain the influences of the miscellaneous wave interference produced in the working of the machine on other equipments via a power supply loop. By entering into the front end of the machine power supply, the function of wave filtration can be effectively broughtinto full play, thus letting the machine have better anti-interference capability in the increasingly serious ambience of electromagnetic interference and have more stable working performance and thestate of the machine.

Description

technical field [0001] The invention relates to a fuse, in particular to a fuse with filter function. Background technique [0002] The AC power we use is basically transmitted from the outdoor power transmission main line to the user's ammeter, and then enters the user's sub-main line. The electric meter of each household is connected in parallel with the electric meters of many users, and all externally induced interference and noise will enter the user's home along with the transmission and distribution lines, such as natural lightning strikes, various communication broadcasts, radio transmissions, and cars passing by nearby residents. , electric equipment work, etc., will affect the quality of our indoor power supply. Unpurified power supply will affect the use of precision instruments, especially sensitive audio-visual equipment. Using impure power supply will increase the background noise of the sound and image of audio-visual equipment, which will affect the effect o...
