Claims
- 1. A large-current fuse unit, comprising:
- a large-current fuse including a pair of terminals, and a fuse element interconnecting said pair of terminals;
- a housing receiving said large-current fuse therein; and
- a temperature fuse mounted in said housing, and being meltable by heat generated from said fuse element to open said temperature fuse;
- wherein, during a normal operating condition, a current flowing through said large-current fuse does not flow through said temperature fuse.
- 2. A large-current fuse unit according to claim 1, wherein the melting of said temperature fuse one of activates an alarm circuit and activates a forced breaking circuit.
- 3. A large-current fuse unit according to claim 1, wherein an operating temperature of said temperature fuse is set to a value between an operating temperature of said large-current fuse and a maximum temperature which can develop in a normally-used condition of said large-current fuse.
- 4. A large-current fuse unit comprising:
- a large-current fuse including a pair of terminals, and a fuse element interconnecting said pair of terminals;
- a housing receiving said large-current fuse therein; and
- a temperature fuse mounted in said housing, and being meltable by heat generated from said fuse element;
- wherein said temperature fuse includes a pair of lead portions, and an element receiving portion interconnecting said pair of lead portions, said element receiving portion being disposed to intersect said fuse element; and
- wherein the melting of said temperature fuse one of activates an alarm circuit and activates a forced breaking circuit.
- 5. A fuse unit comprising:
- a housing;
- a current fuse mounted in said housing; and
- a temperature fuse mounted in said housing, and being meltable by heat generated from said current fuse to open said temperature fuse;
- wherein, during a normal operating condition, a current flowing through said current fuse does not flow through said temperature fuse.
- 6. A fuse unit according to claim 5, wherein the melting of said temperature fuse one of activates an alarm circuit and activates a forced breaking circuit.
- 7. A large-current fuse unit according to claim 5, wherein an operating temperature of said temperature fuse is set to a value between an operating temperature of said current fuse and a maximum temperature which can develop in a normally-used condition of said current fuse.
- 8. A fuse unit comprising:
- a housing;
- a current fuse mounted in said housing; and
- a temperature fuse mounted in said housing, and being meltable by heat generated from said current fuse to open said temperature fuse;
- wherein, during a normal operating condition, said current fuse and said temperature fuse are not electrically coupled together.
- 9. A fuse unit according to claim 8, wherein the melting of said temperature fuse one of activates an alarm circuit and activates a forced breaking circuit.
- 10. A large-current fuse unit according to claim 8, wherein an operating temperature of said temperature fuse is set to a value between an operating temperature of said current fuse and a maximum temperature which can develop in a normally-used condition of said current fuse.
