Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a fuse with a support. Background Art

[0002] A fuse is an electrical device that generates heat to melt its fuse element, disconnecting the circuit when the current exceeds a specified value. A fuse is a current protector that uses the principle that, after the current exceeds a specified value for a period of time, the heat generated by the fuse element melts, thereby disconnecting the circuit. Fuses are widely used in high and low voltage power distribution and control systems, as well as in electrical equipment. As a short-circuit and overcurrent protector, they are one of the most commonly used protective devices.

[0003] Chinese patent 201520307444X discloses a high-current fast-acting fuse comprising a body comprising a fuse tube, a melt disposed within the fuse tube, and conductive plates disposed at both ends of the fuse tube. The ends of the melt tube are electrically connected to the two conductive plates, respectively. The fuse tube is filled with an arc-extinguishing medium. Heat dissipation holes are provided on the sidewalls of the fuse tube to dissipate heat within the fuse tube and cool the melt tube. The conductive plates are provided with connection holes for connecting to an external busbar.

[0004] The fuse in the above patent is fixed to the external busbar in the distribution cabinet through the conductive plate during installation, so the entire weight of the fuse is applied to the conductive plate. However, since the outer shell of the fuse is made of ceramic material and the interior is filled with quartz sand, the fuse is heavy. The greater the current it carries, the heavier the fuse is. Long-term support by the conductive plate can easily cause the conductive plate to bend or even be damaged, affecting the service life of the fuse. Utility Model Content
