The Chinese patent application of Publication No. CN201804828U discloses a kind of Fuse box, and the Fuse box includes
Fuse box body, is provided with locking plate by inserts on described fuse box body, is provided with protecting cap and melts on fuse box body
Disconnected device lid.
Existing fuse cannot transmit the signal that opens a sluice gate or close a floodgate.
Content of the invention
It is an object of the invention to provide a kind of fuse, the fuse that the present invention is provided can be transmitted opens a sluice gate or closes a floodgate
And the signal for whether fusing.
For achieving the above object, the present invention provides a kind of fuse, and the fuse includes hollow housing and is located at
Fuse cylinder in the housing, the fuse also include that the detector that breaks, the broken string detector are enclosed within outside the housing
All and described fuse cylinder passes through the broken string detector, the broken string detector to dock shape by two semiorbicular plastic casings
Become annular, in one of plastic casing, accommodate semiorbicular iron core and the coil being wrapped in outside the iron core, institute
State coil to be introduced in the plastic casing by the plastic casing and draw the plastic casing after being wrapped in the iron core outside
For transmitting signal.
Preferably, the electric wire is introduced and drawn by outlet terminal.
Preferably, the fuse also includes inlet wire mouth positioned at the housing tip, is located at going out for the lower housing portion
Line mouth, the inlet wire mouth are provided with incoming line, and the outlet nozzle is provided with line outlet.
Preferably, the top of the housing is provided with for electrically connecting the upper electrode of the electric wire that the incoming line is entered,
The bottom of the housing is provided with for connecting the lower electrode of the electric wire that the line outlet is drawn.
Preferably, the lower electrode is formed as annular and is enclosed within the periphery of the fuse cylinder.
Preferably, the fuse also includes that the extinguishing arc cylinder in the housing, the fuse cylinder are housed inside institute
State in extinguishing arc cylinder.
Preferably, the extinguishing arc cylinder is urea-formaldehyde materials.
Preferably, the bottom of the housing is provided with closure.
Preferably, the opening passed through for the fuse cylinder is provided with the closure.
The invention has the advantages that:
Compared with prior art, present patent application has the technical effect that:
1. windproof, anti-pollution.Because using interpolation type structure, not only not falling off to the wind, and also add conductor contact surface,
Solve the problems, such as the arc short-circuit that switching on is caused when operating;Top seal, can be greatly lowered environmental pollution, and sand and dust
Erosion with sleet.
2. anti-fault-free comes off.Using the fuse of new structure, it is to avoid as dust storm, vibrations, overload, weather become
Change, the impact of the natural environment such as hot and cold.
3. closing success rate is high.Because the fuse of new structure is had with the different part of old-fashioned fuse:1. novel spraying
The fuse for penetrating formula fuse is not subject to pulling force;2. do not limited by fusion tube length;3. fast, success rate of closing a floodgate is high, conductive contact surfaces
Greatly.First, the fuse of old-fashioned fuse will be easy to moment disconnection, need to take because of the pulling force by more than 50N in closing operation
Get off the fuse for renewing again, because during fuse is changed causing upper and lower contact distance to change, is stranded will combined floodgate
Difficult;Secondly, when fusion tube is more renewed, because of corresponding problem, adjustment is difficult, through equipment adjustment after, flexibility ratio and fitness are possible to
Original state not being reached, closing success rate being caused than relatively low, the conduction contact part of old-fashioned fuse mostly is line and small area contact,
Operational reliability is poor.
4. circuit operational efficiency is high.
5. fuse by melt itself, form electric arc, then under high arc temperature effect, the gas exhausted material in arc cylinder will be cut
After gasification, a large amount of gases are produced, by arc blow out.
6. solving existing fuse does not have the defect of visual fracture.By fracture detector, fuse can be detected
Inside is to close a floodgate or gate-dividing state, while providing signals to subordinate's process.
