Abstract
The utility model provides a fast fusing speed and nonexpendable mercury fuse. The mercury in a mercury passage connects with two connection terminals, the mercury passage communicates with a gas chamber and the gas chamber is tightly sealed and the mercury is in the gas chamber. When the overloading or the short circuit happens, the mercury column rapidly expands and is disconnected, the mercury in the mercury passage ejects into the gas chamber occurring the powerdown. After the powerdown, the fuse is taken off and is rocked horizontally then the mercury injects into the mercury passage so as to reuse.
Description
The utility model relates to a kind of Mercury fuse, as the safeties of electrical equipment.
In the prior art as group's core formula fuse 85203813 be to finish fusing process several times by several fusible link change in location, so the fusing number of times is subjected to the restriction of fuse radical, and fusing time is long; No fuse failure device 85201165 is principles of utilizing thermocouple, and it can only play overload protection, and can not play short-circuit protection, and fusing time is also longer.
The purpose of this utility model be to provide a kind of reliably, can repeatedly use, both can play the fuse that short-circuit protection also can play overload protective function, and fusing speed is fast.
Task of the present utility model is finished in the following manner: binding post is coated epoxy resin and housing bonds together, mercury in the mercury channel links to each other two binding posts, mercury channel communicates in air chamber, inject mercury in the air chamber, then air chamber is sealed, air chamber is positioned at the opposite side of two binding posts, the diameter of fuse mercury channel needs to change according to the rated current size of the electrical equipment that links with it, rated current is big more, and the diameter of mercury channel is big more, otherwise more little, after the energising, when overload does not take place or during short circuit, the shortage of heat that electric current produced by mercury between two binding posts so that mercury expand, disconnect, do not produce the outage phenomenon; When overload or short circuit take place when, the heat that electric current produced by mercury make the disconnected son of two wiring between mercury expand rapidly, disconnect, the mercury in the mercury channel is ejected in the air chamber, formation is opened circuit.
Advantage of the present utility model is that fusing speed is fast, and can repeatedly use, and after the outage, fuse is taken off each time; horizontal positioned is shaken several times, after mercury injects mercury channel; just can reuse, this fuse both can be used for short-circuit protection, also can be used for overload protection.
Accompanying drawing is the cutaway view of the utility model Mercury fuse.
The utility model is described below in conjunction with accompanying drawing.
With binding post 1,6(conductor) coat epoxy resin and housing 5(bakelite or pottery) bond together, inject mercurys to gas chamber volume 1/2～1/10 to air chamber 3, use seal cover 2(bakelite then) air chamber is sealed.With the fuse horizontal positioned, shake several times after finishing, make the interior mercury of air chamber fill with mercury channel 7, connect two binding posts.
Claims (2)
1, a kind of have a binding post 1,6, the Mercury fuse of housing 5, the mercury channel 7 that it is characterized in that continuous two binding posts 1,6 communicates with the air chamber 3 of its opposite side, fill mercury in the mercury channel 7 and connect two binding posts, fill mercury 4 in the air chamber, relative air chamber of housing and mercury channel seal.
2,, it is characterized in that housing 5 is that insulating material is made according to the said fuse of claim 1.
