The protector of overcurrent, is to apply one of most common protection device.Fuse can divide according to use voltage
For high-tension fuse and low-tension fuse.Protection transformator can be divided into with the most electric according to protection object
The fuse of equipment, the fuse of protection voltage transformer, the protection fuse of power capacitor, guarantor
Protect the fuse of semiconductor element, the fuse of protection motor and the fuse etc. of protection household electrical appliance.
Open type, semi-enclosed, tubular type and expulsion fuse can be divided into according to structure.Open type fuse is tied
Structure is simple, and melt is completely exposed in air, porcelain knob support, and does not has bearing, is suitable to low voltage outdoor and uses.
Bigger acousto-optic is produced in an atmosphere during breaking current.The melt of semi-enclosed fuse is contained on porcelain frame,
Insert in the porcelain box with metal consent of the two ends, be suitable to the indoor use of low pressure.During breaking current, produced sound
Light is blocked by porcelain box.
But in use there are some defects, such as, present electric power in present power fuse
Fuse breaks down when keeping in repair, and on the one hand to look for is which power fuse occurs in that fault, the opposing party
Face to be also very inconvenient with standby fuse.
Utility model content

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Fig. 1, a kind of technical scheme of this utility model offer: a kind of electricity conveniently with emergency function are provided
Power fuse, including upper terminals 1, fuse converter 5, lower moving contact 9, lower terminals 10 and fixing
Installing set 13, upper terminals 1 are arranged on the top of upper static contact 15, and the right side of upper static contact 15 sets
Being equipped with moving contact 3, the right side of upper moving contact 3 is provided with convenient operation ring 4, and conveniently operates ring 4
