Abstract
The invention relates to a high-current fuse, which is used for protecting devices, such as a secondary battery with the carrying rated current of dozens of amp and even hundreds of amp, and the like. The high-current fuse comprises a special non-metal support base, which is used for supporting two metal planar electrodes in parallel. The metal planar electrodes also are high-current terminals connected to a main loop. A plurality of alloy silks with low melting point are connected in parallel to form a fuse capable of bearing high current through the planar electrodes. A resistance heating body tightly and thermally coupled with the planar electrodes is also designed in the high-current fuse. The current of the heating body is supplied by another power supply loop. Under normal conditions, no current flows through the power supply loop; when the current in the main circuit is too high, the voltage is too high, and the temperature of a storage battery is too high, a monitoring circuit sends out instruction so that a heating circuit is electrified; the temperature of the metal planar electrodes can be increased through the heat of the heating body so that the main fuse is molten; furthermore, under the action of assistant fusing agent, each alloy silk can be well disconnected; and a small temperature fuse, temperature of which is higher than the melting temperature of the main fuse, is connected with the heating body in series, therefore, the main fuse is disconnected at first.
Description
Technical field
The present invention relates to a kind of large current fuse, particularly the large current fuse of a kind of protecting secondary battery being operated under low-voltage
Background technology
In recent years, the technological development of secondary cell is showing improvement or progress day by day, wherein for the electrokinetic cell of various uses also along with growing up.Electric bicycle, tour bus, big bus, electric automobile, communication, post and telecommunications, railway, the fields such as military boats and ships, it,, by driving the flourish of whole dynamic lithium battery industry, is being promoted with green, and environmental protection is pollution-free, the high efficiency new forms of energy that can recycle.Generally, the discharging current of these power battery pack is all more than tens amperes, and what have even reaches hundreds of ampere.Due to being widely used of electrokinetic cell, produced a problem that discharging and recharging of power battery pack protected.For example occurred a kind of power battery management system that has electronic circuit to form, it is the system of being switched by a kind of contactor of electronic circuit control.But this contactor volume is larger, cost is relatively high, and owing to adopting contact incoming current to cut off, also there will be contact to bear the ability of electric current simultaneously, and the hidden danger brought of self-contact resistance.
Summary of the invention
A kind of large current fuse of the present invention, it comprises:
Main fuse-link, consists of many low-melting alloy silks, is filled with the disconnected agent of fluxing of shrinking to two end electrodes for after causing melting alloy wire in the surrounding of B alloy wire;
Pair of metal electrodes (6) and (7);
