Problems solved by technology

In the prior art, the shape of the fuse cartridge is as follows: figure 1 As shown, it is necessary to apply silicone grease to the rubber during installation, and use silicone grease to connect the rubber and the cabinet shell. The installation process is laborious, and as time goes by, the fuse tube and the portable cover will stick to the electrical cabinet shell In general, the fuse cartridge is a component that needs to be replaced frequently. If it is stuck to the electrical cabinet, it will cause great inconvenience to disassembly and affect the sealing performance of the next installation.

Abstract

The invention discloses a fuse unit convenient to dismount. The fuse unit comprises a unit frame of a U-shaped structure, wherein a fuse tube is installed in the unit frame, an elastic body is arranged at one end of the fuse tube, the end, away from the unit frame, of the elastic body is connected with a seal cap, the seal cap is matched with a hand-lifted cap through a rotary shaft, the rotary shaft is sleeved with a spring, and a fixing part is also arranged on the rotary shaft. The fuse unit convenient to dismount is simple in installation and convenient to dismount, time and effort are saved, and follow-up installing precision is not affected.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a fuse cartridge which is easy to assemble and disassemble. Background technique [0002] In the field of power equipment, high-voltage ring network cabinets usually use sulfur hexafluoride (SF6) gas to insulate the components in the cabinet from the outside world. When the current is too large, it can cut off the circuit and make the tripping thimble action to realize tripping, so as to protect the switch cabinet. The outside of the fuse tube is provided with a fuse tube for protecting the fuse tube. After using the fuse tube, the installation and maintenance of the fuse tube in the sulfur hexafluoride gas high-voltage switchgear are very simple. In the prior art, the shape of the fuse cartridge is as follows: figure 1 As shown, it is necessary to apply silicone grease to the rubber during installation, and use silicone grease to connect the rubber and the cabinet shell. Th...
