[0002] Fuse is the simplest protective device. It is used to protect electrical equipment from overload and short-circuit current damage. We often say that fuses are fuses. Fuses are connected in series with melts made of metal materials with a lower melting point. In the protected circuit, when the circuit or the equipment in the circuit is overloaded or fails, the fuse will heat up and melt, thereby cutting off the circuit and achieving the purpose of protecting the circuit or equipment. However, after the existing fuse is damaged, it is necessary to repair the fuse Repairing or replacing the melt after the overall disassembly and assembly is performed. The disassembly of the existing fuse is cumbersome and requires the aid of auxiliary equipment to complete the disassembly, which greatly prolongs the power outage time. Therefore, the inventor designed a fuse that can quickly and easily replace the melt. device

Embodiment Construction
[0094] A quick replacement method for a circuit fuse protector, the steps of which are as follows:
[0095] S1: The fuse 200 installed in the housing 100 is blown;
[0096] The fuse tube 200 includes a glass tube 210, a trigger lever 240, a transition plate 250, a melt 260, and a compression spring 270. The glass tube 210 is a circular cylinder with two ends open, and the open ends of the glass tube 210 are coaxially matched and installed. There is a conductive pipe head, which is a circular cylinder with one end open and one end closed, and the open end of the conductive pipe head is coaxially fixed to the open end of the glass tube 210. There are two sets of conductive pipe heads corresponding to the conductive pipe heads. One 220, conductive pipe head two 230, the closed end of the conductive pipe head one 220 is coaxially provided with an avoidance hole, the transition plate 250 is coaxially installed in the conductive pipe head one 220 to form a sliding guide fit, and the...

The invention discloses a method for intelligent protection and quick replacement of a circuit. The method comprises the following steps that melt of a working fuse tube is fused, and then the elasticforce of a compression spring enables the free end of a trigger rod to extend out of a conductive tube head; when the free end of the trigger rod extends out, the free end of the trigger rod is in contact with pushing and unloading mechanism and enables the pushing and unloading mechanism to be switched to a pushing and unloading state, then a separation rod moves and enables a clamping mechanismto be switched to a spreading state in advance, and then the pushing and unloading mechanism moves and pushes a working safety tube out of a shell through a discharge opening; when a trigger pushingand unloading device is triggered, a conductive contact mechanism is switched to a disconnection state, and the circuit is disconnected in time; the user manually makes the whole pushing and unloadingmechanism move away from the clamping mechanism, and simultaneously a replacement mechanism pushes a replacement fuse tube positioned in a guide area of the clamping mechanism into a clamping area ofthe clamping mechanism, and the replacement fuse tube becomes a new working fuse tube, and after the replacement is finished, the conductive contact mechanism is again switched to a closed state, andthe whole circuit is closed at the moment.
