Abstract

The present invention relates to a manufacturing method of an EV fuse. The manufacturing method of the EV fuse comprises the following steps: mixing and stirring raw materials evenly to obtain solidified sand, and the solidified sand includes the following components in parts by mass: 95 parts of mixed quartz sand 99 parts, 0.5 to 1 part of curing agent, and 0.5 to 2 parts of water, wherein the mixed quartz sand includes the following components by mass: 35 to 45 parts of 70 mesh quartz sand, 20 parts of 60 mesh quartz sand to 30 parts, 20 parts to 30 parts of 50-mesh quartz sand, and 5 parts to 15 parts of 40-mesh quartz sand; solidify the solidified sand, place the solidified sand in the fuse housing, and fuse the The fuse housing is placed into a curing device, and the curing device adds high-temperature water vapor into the fuse housing under a pressure of 0.05 bar to 0.15 bar.

Description

technical field [0001] The invention relates to the field of manufacturing EV fuses, in particular to a method for manufacturing EV fuses. Background technique [0002] Fuses are widely used in low-voltage power distribution systems, control systems, and electrical equipment. As short-circuit and over-current protection, fuses are one of the most commonly used protection devices. The fuse is mainly composed of two parts, the melt and the fuse tube, and external fillers. The fuse is connected in series in the circuit to be protected during the working process. When the current of the protected circuit exceeds the specified value for a period of time, the heat generated by the melt itself will fuse the fuse and disconnect the circuit, thereby protecting the circuit. When the overload current is small, the fusing time is long, and when the overload current is large, the fusing time is short. In the overload current range until the current returns to normal, the fuse will not ...
