A fuse installation device

Abstract

The invention discloses a fuse installation device, which comprises a base, a fuse and a ceramic insulator. Both ends of the ceramic insulator are provided with clips, and the base is provided with several sets of clips for installation near the surfaces of both ends. holes, fastening bolts are provided between the clamp and the mounting hole, connecting screws are provided at both ends of the ceramic insulator, and conductive connecting plates are sleeved on the surfaces of the two connecting screws, and the conductive connecting plates are A terminal is provided on the side, a fixing screw is fixedly connected to one end of the top of the conductive connecting plate, and a fuse fixing device is arranged between the two fixing screws. The invention is equipped with a fuse fixing device, which is beneficial to adopt a press-type fixed fuse method to prevent the fuse from being rotated and fixed, causing the conductive spring chip to be twisted and damaged, and through the action of the chute of the fixed end piece, the fuse can be effectively made Properly install according to the length of the ceramic insulator.

Description

technical field [0001] The invention relates to the technical field of fuse equipment, in particular to a fuse installation device. Background technique [0002] A fuse is 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] Generally, the fuses used in rail transit are usually installed together with ceramic insulators and fuses to form high-voltage drop-out fuses. However, during the installation process of ce...

Problems solved by technology

[0003] Generally, the fuses used in rail transit are usually installed together with ceramic insulators and fuses to form high-voltage drop-out fuses. However, during the installation process of ceramic insulators and fuses, due to the length of The models vary, so in the process of installing the fuse and the ceramic insulator, the installation is inconvenient, and the fuse cannot be adapted to ceramic insulators of different lengths, and generally the two ends of the fuse are often installed by screwing. During the process, the conductive sheet is prone to loosening, which may easily cause poor contact and affect the function of the power-off protection of the fuse
