PROCESS FOR MANUFACTURING COMPOSITE LAMELLA PACKAGES OF DETACHABLE TYPE FOR VOLTAGE CORES OF INDUCTIVE POWER METERS FROM PARTIAL LAMELLA PACKAGES

摘要

The yoke lamella (11) located in the same level of the lamellar core package (5) for the lamellar partial yoke package (51), and the pole lamella (12) for the lamellar partial pole package (52) are always manufactured by partial cuts. In its central leg (112) of the yoke lamella (11) sector, two parallel single separation partial cuts (1, 1') are performed, which are almost symmetrical to the longitudinal axis of this leg (112) and approximately parallel to the lamella. Together with the partial cuts (b, c2, c2') they separate the central leg (112) from the pole lamella (12). Subsequently, the central leg (112) is shortened by partial cuts (c1, c1'), which on one side and the other of the single separating partial cuts (a, a') are leading approximately at a right angle against it and in the extension of each other. Between the lamellar partial packages (51, 52) of the yoke or pole, which are made according to an improved process, they provide a good mechanical and a timely stable magnetic contact, the pressing and extracting force do not change with the increase in the number of prints.
