Abstract:
The invention provides an overcurrent protection device ( 1 ), comprising a current input terminal ( 2 ); a central terminal ( 3 ) for the output of current overshoots (I s ); and a terminal ( 4 ) for the output of non impulse currents (I c ) which is outwardly connected to the voltage of the central terminal ( 3 ) before the occurrence of the current overshoot (Is) at the input terminal ( 2 ); and an electrical conductor element ( 5 ) connected between the current input and output terminals ( 2  and  4 ); such conductor element showing a reduced self-induction (L) when operating without current overshoots but, which, in case that current overshoots are present at the input terminal ( 2 ), produces a high drop of the induction voltage between such input terminal and the output terminal ( 2  and  4 ); wherein the central terminal ( 3 ) is arranged in the vicinity of the current input terminal ( 2 ) at a distance (D) that may be regulated, so that when, as a result of a current overshoot, the inductive voltage drop between the input terminal and the non-impulse current output terminal ( 2  and  4 ) exceeds the dielectric strength of the dielectric material present between the input and central terminals ( 2  and  3 ), and thanks to the skin effect, an arc is generated between such input and central terminal ( 2  and  3 ), thus preventing the flow of current overshoots (Is) through the conductor element ( 5 ).

Claim (Index 1):
An overcurrent protection device for electrical circuits, comprising:\n a current input terminal ( 2 ); a central terminal ( 3 ) for an output of current overshoots (I s ); and an output terminal ( 4 ) for an output of non impulse currents (I e ) which is outwardly connected to a voltage of the central terminal ( 3 ) before an occurrence of the current overshoot (Is) at the current input terminal ( 2 ); and an electrical conductor element ( 5 ) connecting the current input terminal ( 2 ) and the output terminal ( 4 ), the electrical conductor element having reduced self-induction (L) at current levels below the overcurrent condition and the electrical conductor element having greater self-induction at the overcurrent condition such that when operating without current overshoots but, which, in case that current overshoots are present at the current input terminal ( 2 ), a high inductive voltage drop (\u0394U i =L\u00b7dl s /dt) is established between the current input terminal ( 2 ) and the output terminal ( 4 ); wherein the central terminal ( 3 ) is firmly arranged in the vicinity of the current input terminal ( 2 ) at a distance (D) that can be regulated, so that, when the inductive voltage drop (\u0394U i ) between the current input terminal ( 2 ) and the output terminal ( 4 ), as a result of a current overshoot, exceeds a dielectric strength of a dielectric material present between the input and central terminals ( 2  and  3 ), also as a result of a skin effect, an electric arc is generated between the current input terminal ( 2 ) and the central terminal ( 3 ), eliminating the flow of the current overshoots (I s ) through the electrical conductor element ( 5 ) wherein the overcurrent protection device is used on an associated limiter fuse ( 12 ) resistant to current overshoots, wherein the associated limiter fuse ( 12 ) respectively comprises: a first ( 120 ) and a second ( 121 ) connection capsules; a first contact portion ( 122 ) which is connected to the first connection capsule ( 120 ) and a second contact portion ( 123 ), separated from the first portion, connected to a main fusible element ( 124 ) which is arranged following a spiral layout around a central core ( 125 ); a third contact portion ( 126 ) which is adjacent to the second contact portion and which is electrically insulated from the second portion by means of an insulating portion ( 127 ), wherein a secondary fusible element ( 1240 ) which is resistant to current overshoots and which is also arranged following a spiral layout around the central core ( 125 ) parallel to the main fusible element ( 124 ) is connected to said third contact portion; a fourth metal contact element ( 128 ) which is connected to the second connection capsule ( 121 ), wherein the overcurrent protection device ( 1 ) is connected to a fuse link ( 12 ) with the current input terminal ( 2 ) connected to the first contact portion ( 122 ), the output terminal ( 4 ) connected to the second contact portion ( 123 ) and the central terminal ( 3 ) connected to the third contact portion ( 126 ) through a non-fusible connection conductor ( 13 ), and wherein the over current protection device is used on a fuse link ( 10 ) resistant to impulse currents.
