Description

Wynalazek dotyczy urzadzenia stykowego o stykach wstepnych i glównych z podwójnym przerywaniem, dzieki któremu osiaga sie znacz¬ ne zmniejszenie wymiarów konstrukcyjnych aparatury wylacznikowej, na skutek odpowied¬ niego rozmieszczenia i ksztaltu styków wstep¬ nych i glównych.Wymiary, a w szczególnosci szerokosc apara¬ tury wylacznikowej jest w wysokim stopniu uzalezniona od wymiarów szyn pradowych.Szerokosc szyny pradowej jest z góry ustalona odpowiednio do wartosci przewodzonego pradu oraz rozlozenia na niej zacisków dolaczeniowych.Jezeli urzadzenie stykowe wymaga poszerze¬ nia szyny pradowej ponad minimalny rozmiar, *) Wlasciciel patentu oswiadczyl, ze twórca wyna¬ lazku jest Herbert Boxleidner wynikajacy z warunków pradowych oraz dola¬ czeniowych, nalezy przy tym miec na wzgledzie to, ze szczególnie przy wielobiegunowych apara¬ turach wylacznikowych, otrzyma sie duza sze¬ rokosc aparatury. Przy wlacznikach dzwignio¬ wych z przerywaniem pojedynczym, wystarcza¬ ja zwykle te minimalne wymiary szyny pra¬ dowej, poniewaz równolegle laczenie styków wstepnych z glównymi jest mozliwe, w zakresie tej szerokosci, za pomoca tasm podatnych.Inaczej ksztaltuja sie warunki przy zastosowa¬ niu styków wstepnych i glównych z bardziej ko¬ rzystnym, podwójnym, przerywaniem, które mie¬ dzy innymi nie wymaga tasm podatnych i wyka¬ zuje krótsze drogi laczeniowe. Biegun pradowy musi byc jednak tutaj podzielony na dwa stale równolegle odgalezienia. Proponowane bylojak to przedstawiono na fig. 3 i 4, wykorzystac w pelni na korzysc dostatecznie szerokich sty¬ ków, uzalezniona od warunków pradowych i do- laczeniowych minimalna szerokosc szyny pra¬ dowej 7', 7" przy zachowaniu potrzebnych odste¬ pów powietrznych i przewidzianych ze wzgledu na wystepowanie pradów pelzajacych. Dodat¬ kowe pogrubienie odgalezien pradowych mozna osiagnac przez to, ze jak np. wedlug fig. 1, odga¬ lezienia pradowe 3, 4 zostaja poszerzone i wpu¬ szczone ponizej górnej powierzchni plyty pod¬ stawowej 6. Uruchamianie styków ruchomych nastepuje przeciwbieznie, wedlug fig. 1 w zna¬ ny sposób za pomoca dzwigni dwuramiennej 5 i popychaczy, przy czym popychacze sa prowa¬ dzone przez oddzielone od siebie przestrzennie styki wstepne lub glówne oraz w odpowiednio uksztaltowanej plycie podstawowej. Zamiast ta¬ kiego sposobu uruchamiania styków moze oczy¬ wiscie znalezc zastosowanie, przy urzadzeniach stykowych ze zgodnym kierunkiem ruchu, pod¬ noszona i opuszczana poprzeczka.Aparaty lacznikowe z urzadzeniem stykowym wedlug wynalazku odpowiadaja wymaganiom praktycznym ze wzgledu na minimalna szero¬ kosc ich konstrukcji, latwy dozór i kontrole sty¬ ków oraz nieskomplikowane narzady do napedu styków ruchomych. PLThe invention relates to a contact device with double-break primary and primary contacts, thanks to which a significant reduction in the design dimensions of circuit breaker devices is achieved due to the appropriate arrangement and shape of the primary and main contacts. Dimensions, and in particular the width of the circuit breaker device. is highly dependent on the dimensions of the busbars. The width of the busbar is predetermined according to the value of the conducted current and the distribution of the connection terminals on it. If the contact device requires the expansion of the busbar beyond the minimum size, *) The patent holder has declared that According to the invention, the Herbert Boxleidner is based on the current and connection conditions, bearing in mind that especially with multipolar circuit breaker devices, a large width of the apparatus will be obtained. In the case of single-break toggle switches, usually these minimum dimensions of the current bus are sufficient, because the parallel connection of the primary contacts with the main contacts is possible, within this width, by means of flexible bands. Otherwise, the conditions for the use of contacts are shaped. initial and main lines with the more preferred double break, which, inter alia, do not require flexible tapes and have shorter connecting paths. The current pole, however, must here be divided into two continuously parallel branches. It was proposed, as shown in Figs. 3 and 4, to use fully, in favor of sufficiently wide contacts, the minimum width of the current busbar 7 ', 7 "depending on the current and connection conditions, while maintaining the necessary air gaps and Due to creeping currents, an additional thickening of the current branches can be achieved by the fact that, for example according to Fig. 1, the current branches 3, 4 are widened and recessed below the upper surface of the base plate 6. Activation According to FIG. 1, the movable contacts are reversed in a known manner by means of a two-arm lever 5 and pushers, the pushers being guided through spaced-apart primary or main contacts and in a suitably shaped base plate. actuating the contacts can of course find application, with contact devices with the same direction of movement, lifting and lowering pop Switching devices with a contact device according to the invention meet practical requirements due to the minimum width of their construction, easy supervision and control of the contacts and simple tools for driving the movable contacts.

Claims

Claims 1. A double-break contact device with primary and secondary contacts, characterized in that it has, along the current rail (7 "), two permanent (V, 1") contacts and two fixed main contacts (2 2 "), spatially and electrically separated from each other and so arranged that the longitudinal axes of the two preliminary contacts run parallel on one side, and the longitudinal axes of both main contacts run parallel on the other side with respect to the longitudinal axis of the current rail, with whereby each of the fixed initial contacts is connected to one of the fixed main contacts through one of the external side of them and set with a greater dimension of their cross-section perpendicular to the width of the rail, current branches (3, 4), and coincides the width of one additional contact (V) and next to it the current branch (3) along with the air gap and the section provided for the occurrence of creeping currents, or one the main contact (2 ') and the current branch (4) next to it, together with the air gap and the section provided for the occurrence of creeping currents is equal to or smaller than the width of the current rail (7', 7 "), depending on the size of the current and connection conditions.
