A kind of fuse unit
Technical field
The utility model belongs to technical field of electric equipment, and in particular to a kind of fuse unit.
Background technology
Fuse in fuse unit utilizes its low fusing point, fuse when electric current in circuit increases suddenly in fuse It is blown so that closed circuit is disconnected so as to achieve the purpose that to protect equipment in circuit.
Existing fuse unit is generally sealed in the form of electro-insulating rubber circle, and the heat dissipation performance of electro-insulating rubber circle Difference, the heat for causing to produce inside fuse unit cannot be quickly spread so as to cause the accumulation of heat, when the electric current in circuit not When reaching the blowout current of fuse, disconnected since the accumulation of heat result in fuse so that the equipment in circuit stops work suddenly Make, so damage equipment and the replacement for causing unwanted fuse unit.
Utility model content
The purpose of this utility model is that for fuse unit internal heat can not normal discharge cause heat build-up, finally make Obtaining fuse and disconnecting influences the problem of normal work of equipment and fuse are often replaced in circuit, and the utility model provides a kind of Fuse unit.
The technical solution adopted in the utility model is as follows:
A kind of fuse unit, including cylinder, the cylinder both ends are connected to deck and inlet wire portion, are set on the cylinder There are outlet portion, grounding parts and central control interface, be provided with fuse in the cylinder, fuse one end is arranged in the deck It is interior, it is arranged with radiator outside fuse;
Radiator includes being sheathed on insulation inner ring outside fuse, is arranged with insulation outer shroud outside insulation inner ring, in insulation The annular chamber of closing is formed between ring and insulation outer shroud, is provided with some partition plates in annular chamber, some partition plates are by the annular chamber It is separated into some not connected coolant storage chambers.
Further limit, the heat-dissipating pipe connected with the coolant storage chamber, heat-dissipating pipe are provided with the insulation outer shroud Through the barrel of the cylinder.
Further limit, transparent tube body of the heat-dissipating pipe including running through the cylinder barrel, tube wall on the outside of transparent tube body On be provided with graduation mark.
Further limit, tube wall is provided with liquid level alarm and gas alarm on the inside of the transparent tube body.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. setting radiator outside fuse, electric current can be taken away maintenance fusing by heat caused by fuse Normal temperature on device;Radiator in coolant storage chamber by being filled with liquid, due to the heat absorption capacity pole of cooling liquid It is strong and be not susceptible to phase transformation, so it is small to the volume requirement of coolant storage chamber, reduce the volume of fuse.
2. some partition plates are set and annular chamber is separated into some not connected coolant storage chambers by some partition plates so that Coolant is as much as possible full of in whole annular chamber, increases the heat exchange with fuse.
3. setting the heat-dissipating pipe connected with coolant storage chamber on insulation outer shroud, a part of coolant enters in heat-dissipating pipe Air is transferred heat to by the tube wall of heat-dissipating pipe, and then the effect further cooled down.
4. setting liquid level alarm and gas alarm on the inner side tube wall of transparent tube body, liquid level alarm is used to detect Because coolant absorbs heat cause liquid level rise and liquid level exceed certain graduation mark when and alarm, prompting staff Check that the abnormal conditions of the equipment on circuit and fuse unit avoid power failure;Gas alarm is used to monitor cooling in heat-dissipating pipe The gasification situation of liquid, so that it is determined that in fuse unit in the accumulation situation of heat and circuit electric current abnormal conditions.
