Embodiment：
It is noted that described further below is all exemplary, it is intended to provides further instruction to the application.It is unless another
Indicate, all technologies used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in this manual using term "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2 is respectively to be insured outside existing panel using chip insurance and air conditioner power source circuit using chip
Schematic diagram；
Fig. 3 is the control panel overcurrent protective device schematic diagram that the utility model uses resettable fuse, including is controlled
Panel power circuit and resettable fuse 11；The resettable fuse 11 is connected on control panel power circuit.
Control panel power circuit includes A/C switches 1, diode 2, relay, resistance 6 and refrigeration lamp 5；A/C switches 1,
Diode 2 and the resettable fuse 11 are connected in series；Relay coil end 3 is in parallel with diode 2；Relay contact end 4,
Resistance 6 and refrigeration lamp 5 are connected in parallel to A/C switches 1 and the both ends of diode 2 again after being connected in series.
Resettable fuse is a kind of excessively stream electrical protection component, using macromolecule organic polymer in high pressure, high temperature, sulphur
Under conditions of changing reaction, after dashing with particulate materials, it is process by special technique.When short circuit or overload occur for circuit
When, flowing through the high current of resettable fuse makes it collect temperature rise, and when reaching Curie temperature, its density of states reduces rapidly, phase
Become increase, internal electrically conductive links become or are broken in snowslide state, and fuse adjourns high-impedance state in phase step type, and electric current is pinched rapidly
