Abstract

Czujnik prądu zawiera zestaw cewek (6) wykonanych w postaci obwodu drukowanego składającego się z laminatu, na którego obu stronach znajdują się pola stykowe połączone z zewnętrznym końcem uzwojeń. Wewnętrzne końce uzwojeń połączone są ze sobą za pomocą przepustu przechodzącego przez laminat, przy czym kierunek zwojów uzwojeń jest jednakowy po obu stronach laminatu. Z jednej strony cewki (6) uzwojenie pokryte jest warstwą izolacyjną. Cewki (6) są ułożone równolegle do siebie i połączone szeregowo za pomocą cienkiej warstwy lutowia (10). Do skrajnych pól stykowych zestawu cewek (6) dołączone są za pomocą lutowia przewody wyprowadzeniowe (11), przy czym cały zestaw cewek (6) jest ułożony wzdłuż szyny prądowej (7), a stałą pozycję cewek względem szyny prądowej zapewnia obejma (9) z materiału nieferromagnetycznego.The current sensor contains a set of coils (6) made in the form of a printed circuit consisting of a laminate, on both sides of which are contact fields connected to the outer end of the windings. The inner ends of the windings are connected to each other by means of a culvert passing through the laminate, where the direction of the winding turns is the same on both sides of the laminate. On one side of the coil (6), the winding is covered with an insulating layer. The coils (6) are arranged parallel to each other and connected in series with a thin layer of solder (10). To the extreme contact fields of the set of coils (6), lead wires (11) are connected by soldering, whereby the whole set of coils (6) is laid along the busbar (7), and the fixed position of the coils relative to the busbar is provided by the clamp (9) with non-ferromagnetic material.
