Abstract

U društvu KONČAR - Generatori i motori d.d. razvijen je i korišten sustav za automatizirano prikupljanje i obradu podataka, iz pokusa praznog hoda, kratkog spoja i pokusa opterećenja asinkronog motora u tvorničkim uvjetima. Sustav se zasniva na računalu upravljanom procesu prikupljanja podataka iz trofaznog analizatora snage, nakon čega se vrši njihova obrada i prikaz rezultata. Sami se podaci se prikupljaju uz pomoć trofaznog analizatora snage, kojemu se na ulaz dovode prilagođeni signali napona i struje motora. Nakon prikupljanja mjernih veličina i njihovog spremanja u datoteku na računalu, vrši se obrada podataka. Ovisno o vrsti pokusa izračunavaju se parametri važni za utvrđivanje ispravnosti stroja. Obrađene je podatke moguće arhivirati u datoteku na računalu ili ih ispisati kao preliminarni izvještaj o ispitivanju. Program koji upravlja mjernim sustavom napisan je pomoću programskog paketa TESTPOINT®.

Abstract (english)

A system for automated acquisition of data from no load test, locked rotor test and load test of an induction machine in factory environment was developed and used in company KONČAR - Generators and Motors. The system is based on computer-controlled acquisition of data from three-phase power analyzer, after which the data is processed, calculated and presented to the user. Before being acquired by the power analyzer, measured voltage and current signals are transformed and adjusted to meet the requirements of power analyzer itself. Depending on the type of test, various parameters, which are important to determine whether the machine is correct, are calculated. The program that controls measuring system is created with software TESTPOINT®.
