Description

jak równiez pomiaru natezenia pradu w fazie T.Przelacznik wedlug wynalazku posiada te zalete, ze mozemy dokonywac wszelkich pomiarów, a szczegól¬ nie natezen pradów w dowolnych fazach pradu trójfazowego bez koniecznosci przerywania doplywu energii do odbiorcy jak np: we wszelkich zakladach przemyslowych, gdzie dokonywanie pomiarów, powoduje przerwe w dostawie energii, czyniac olbrzymie straty produkcyjne. Istotna zaleta jest prostota w budowie przelacznika, jego obsludze, jak równiez dokonywania pomiarów. Ponadto dokonywanie pomiarów tym przelacznikiem jest bardzo dokladne, gdyz eliminuje koniecznosc stosowania wielu przyrzadów pomiarowych, a tym samym wplywa na wyeliminowanie niedokladnosci pomiarowych, wynikajacych ze stosowania róznych przyrzadów. Stosowaie przelacznika eleminuje koniecznosc utrzymywania przyrzadów pomiarowych pod ciaglym napieciem oraz chroni je przed skutkami zwarcia. Przelacznik posiada szerokie zastosowanie w przemysle, technice pomiarowej a szczególnie w laboratoriach i pracowniach elektrycznych. PL PLas well as the measurement of the current intensity in the T phase. The switch according to the invention has the advantage that we can make all measurements, especially the current intensity in any three-phase current phases without the need to interrupt the energy supply to the recipient, e.g. in all industrial plants, where measurements, causes a break in the supply of energy, causing huge production losses. A significant advantage is the simplicity in the construction of the switch, its operation, as well as making measurements. In addition, making measurements with this switch is very accurate, because it eliminates the need to use many measuring devices, and thus helps to eliminate measurement inaccuracies resulting from the use of different devices. The use of the switch eliminates the need to keep the measuring instruments under constant voltage and protects them against the effects of a short circuit. The switch is widely used in industry, measuring technology, and especially in laboratories and electrical laboratories. PL PL

Claims

1. Patent claim Three-phase packet switch, especially for electrical measurements, characterized by the fact that in the housing (12), having a voltage switch (8), input terminals (5), output terminals (4) and measuring terminals (6), ( 7), there is a switch having at least three current segments (9) and three voltage segments (10), each of which has at least six contact contacts (11), the contacts of the current segments being so constructed that when switching of the switch with the knob (1) from one position to the other, the adjacent contacts of the current segments (9) are previously closed, and then, when they are in the position determined for a given position, they are open for one of the measurement phases. 21 c, 39/01 79 666 MKP H01h 19/50 Fijl Is: n / A Ur: .ed'J f, PiKL. 21 c, 39/01 79 666 MKP HOlh 19/50 and 12 4 and Rq2 Prac.
