Problems solved by technology

[0003] However, the current fuses have a slow fusing speed, and it is time-consuming and laborious to replace them. At the same time, some fuses with simple structures do not have a better protection measure, and it is easy to cause the melt to splash around, causing danger. Therefore, a quick replacement method is proposed. fuse

Abstract

The invention discloses a fuse of a quickly replaced type, and the fuse comprises a pedestal. The upper surface of the pedestal is provided with a fixed end case and a movable end case, and a fuse assembly is in plug connection between the fixed end case and the movable end case. The pedestal is provided with a transmission self-locking mechanism matched with the movable end case. The fuse assembly comprises a fuse housing, a fuse body, stopping blocks, a fuse elastic part, and sealing covers. The inner cavity of the fuse housing is provided with the fuse body, and two ends of the fuse body are respectively provided with the stopping blocks. The fuse body comprises a fuse and a fuse block, wherein the fuse and fuse block are separated from each other. Two ends of the fuse housing are in clamping connection with the sealing covers, and the fuse elastic part is disposed between the stopping block and the fuse cover. According to the invention, the fuse body is designed to the fuse and the fuse block which are separated from each other, thereby effectively improving the fusing speed. Meanwhile, the fuse assembly can enable the fuse body to be gathered effectively when the fuse body is fused, thereby preventing dripping spattering. Meanwhile, the transmission self-locking mechanism can achieve the one-step installation of the fuse assembly, enables the fuse assembly to be locked, and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of strong electricity, in particular to a quick-change fuse. Background technique [0002] A fuse (fuse) refers to an electrical appliance 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] However, the current fuses have a slow fusing speed, and it is time-consuming and laborious to replace them. At the same time, some fuses with simple structures do not have a bett...
