1884 winter, in Vienna commerce federation revealed their invention in heart. On January 2, 1885, the patent that the first concerned paralell connection files to run transformer in Austria in Qibainuofusiji and heart (№ .37/101) , graph the 19 attached drawing in be this patent. Of the same age on Feburary 2 they 3 people file patent of the 2nd transformer in Austria and Germany (Austrian patent № .35/2446, .40414) of German patent № .
On September 16, 1884, the first transformer that hillock Ci factory makes (1400W, f=Hz, 120/72V, change than 1.67) , it is core of a single-phase shell type, closed circuit (iron wire) transformer. Of the same age, hillock Ci factory still made additionally 4 transformer. Graph 20 for the most primitive Z-D-B transformer.
On May 1, 1885, hungarian Bulapeisi national exposition kicks off, the electric current that single-phase alternator of a 150V, 70Hz gives out, through transformer of 5kVA of factory of 75 hillock Ci (closed circuit core, shunt-wound, shell type) step-down, lighted the 1067 edison bulb of exposition field, the grand occasion with its dazzing brilliance is resounding the world. So, successors try the absurd birthday that served as contemporary and practical transformer on May 1, 1885 to commemorate. Budapest exposition makes hillock Ci factory well-known in the world, the factory receives a batch of order during exposition.
They all are heart type transformer, very as adjacent already as contemporary transformer.
21Z-D-B is G. The transformer that the lab makes Feilanlisi (1885) (3000W, change than 1 ∶ 2 or 1 ∶ 4)
Came in June 1885 in October, z-D-B transformer attended London to invent exhibition, made on the meeting demonstrate. The engineer Bell of company of Gibbs of Gao Lande — expends Er heart (R.Belfield) visited London to invent exhibition, be very interested in Z-D-B transformer. On May 7, 1885, core of the first closed circuit applies for in the United States with Bulashen in Qibainuofusiji, heart
Transformer and the patent that communicate distribution system (№ .352105) .
Cloth of the — in — heart pulls Qibainuofusiji assorted (Z-D-B) transformer is the important milestone on transformer technology phylogeny, the basic structure such as paralell connection of the closed circuit core that it uses, former edge all the time continue to use up to now. Can say Z-D-B transformer already made the structure of contemporary transformer finalizes the design basically, from now on domain of the transmit electricity of alternating current of transformer make one's bow, distribution, effectively drove alternating current popularize application, promoted the development of contemporary communication electric machinery.
1888, hillock Ci factory is overcome to Ha Ersi of — of German Xi Menzi (Simens-Halske) company makes over transformer patent. Before long, company of additionally two Germany also bought the transformer patent of hillock Ci factory. 1890, the company of France, Spain also bought the transformer patent of hillock Ci. From 19 centuries 80 time later period begins, transformer is popularized quickly in Europe, already produced 1000 transformer in all to 1889, break through 10000 to 1899. In 20 centuries before 20 time, hillock Ci factory makes a domain maintain world banner level all the time in transformer.
