Abstract

Fuse element for high breaking capacity fuses in the form of a single strip, which is repetitive in terms of the distribution and shape of throats, the strip has throats arranged in series and grouped in the repetitive sections of the strip, which are double-sided and symmetrical to each other, and each throat is made by way of two cut-outs facing each other with closing arches crossing the double-sided edge of the fuse element; furthermore each throat arranged in series is made by means of two cut-outs parallel to the symmetry axis of the fuse element strip, connected with the cut-outs perpendicular to this axis and crossing its double-sided edge and double-sided throats are made by means of uniform circular sectors facing the symmetry axis of the fuse element strip with their convex parts, characterized in that in the sections of the fuse element strip (1) between the sections (3) with throats arranged in series (2), there is at least one single double-sided throat of any shape and size made by means of circular sectors (5) facing the symmetry axis of the strip (1) with their convex parts.<IMAGE>

Description

Przedmiotem wynalazku jest element topikowy do bezpieczników wielkiej mocy wyłączalnej.The subject of the invention is a fuse element for high breaking power fuses.

Znany z patentu polskiego nr 99 045 element topikowy stanowi co najmniej jeden pasek topika z przewężeniami zgrupowanymi w powtarzających się odcinkach paska. Przewężenia te wykonane są obustronnie i symetrycznie względem siebie. Każde przewężenie stanowią dwa wycięcia utworzone przez krzywe wypukłe zwrócone do siebie zamykającymi się łukami przecinającymi obustronną krawędź paska topika. Każde obustronne przewężenie utworzone jest przez dwa wycięcia równoległe do osi symetrii paska topika połączone z wycięciami prostopadłymi do tej osi i przecinającymi obustronną krawędź paska topika, przy czym stanowią one jednakowe wycinki okręgu zwrócone stronami wypukłymi ku osi symetrii paska topika.The fuse element known from Polish patent No. 99,045 consists of at least one fuse strip with constrictions grouped in repeating sections of the strip. These narrowings are made on both sides and symmetrically to each other. Each constriction consists of two notches formed by convex curves facing each other with closing arcs crossing the double-sided edge of the fuse strip. Each two-sided constriction is formed by two notches parallel to the fuse strip symmetry axis connected to the cutouts perpendicular to that axis and crossing the double-sided edge of the fuse strip, and they are uniform circular segments with convex sides facing the fuse strip symmetry axis.

Według wynalazku element topikowy w odcinkach paska topika między odcinkami z szeregowymi przewężeniami zaopatrzony jest w co najmniej jedno pojedyńcze przewężenie dwustronne o dowolnym kształcie i wymiarach utworzone przez wycinki okręgu zwrócone stronami wypukłymi ku osi symetrii paska.According to the invention, in the sections of the fusible link between the sections with serial constrictions, the fusible link is provided with at least one single two-sided constriction of any shape and dimensions, formed by the circular sections with convex sides facing the axis of symmetry of the strip.

Zaletą wynalazku jest zmniejszenie strat mocy oraz umożliwienie poprawy charakterystyki czasowo-prądowej bezpieczników.The advantage of the invention is the reduction of power losses and the possibility of improving the time-current characteristics of the fuses.

Wynalazek w przykładowym wykonaniu uwidoczniono na rysunku przedstawiającym element topikowy w postaci paska 1 zaopatrzonego w szeregowe przewężenie 2 zgrupowane w powtarzających się odcinkach 3 paska 1, pomiędzy którymi znajduje się pojedyńcze przewężenie 4 utworzone przez wycinki okręgu 5 zwrócone stronami wypukłymi ku osi symetrii paska 1.The invention in an exemplary embodiment is shown in the drawing showing a fusible element in the form of a strip 1 provided with a serial groove 2 grouped in repeating sections 3 of the strip 1, between which there is a single narrowing 4 formed by sections of a circle 5 with convex sides facing the axis of symmetry of the strip 1.
