Rapid switching-on method of fusing circuit

Abstract

The invention discloses a rapid switching-on method of a fusing circuit. The rapid switching-on method of the fusing circuit is characterized in that when a circuit is normal, the current can be transmitted to a protection mechanism under the working state through a wiring mechanism I, and the current can be re-transmitted to the circuit through a wiring mechanism II; after a fuse is fused down ofthe protection mechanism under the working state due to an abnormal circuit, a self-replaceable protection device cannot work due to existence of a plug pin, so that a user or electrician performs fault checking and removal on the circuit abnormity; after the abnormal fault of the circuit is removed, the user or electrician manually pulls the plug pin and enables the plug pin to remove limit on the self-replaceable protection device; and meanwhile, the protection mechanism with the fused down fuse drives the whole self-replaceable protection device to rotate under the matching of a self guideboss and a guide groove, and finally, the next group of protection mechanism can replace the protection mechanism with the fused down fuse; next, the user loosens to enable the plug pin to restore tothe original shape; and meanwhile, the circuit is restored to be normal, and the reciprocating is carried out.

Description

technical field [0001] The invention relates to the field of circuit protection, in particular to a method for replacing a blown melt. Background technique [0002] The fuse is a current protector made by using this principle to melt the melt with the heat generated by itself after the current exceeds the specified value for a period of time, and the fuse is simple in structure and easy to use. It is widely used as a short-circuit and over-current protector in power systems, various electrical equipment and household appliances. It is one of the most commonly used protection devices. Notifying the electrician to repair and replace is very troublesome, so the inventor designed a circuit protector that is convenient and easy to operate for melt replacement. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a method for replacing the melt after blown. The self-replacement protection devi...
