Abstract
The invention discloses an annealing process for an amorphous alloy transformer, and belongs to the technical field of power distribution equipment. Optimum values such as heat preservation temperature and the like of an iron core are determined by exploring the annealing process for the iron core of the amorphous alloy transformer for a long time by our company and repeated trial, so as to ensure the load loss and the excitation power of the iron core to be lowest after annealing.
Description
Affiliated technical field
The present invention is a kind of amorphous alloy transformer annealing process, belongs to the power distribution equipment technical field.
Background technology
Amorphous alloy transformer mainly is made up of iron core, coil, folder, transformer oil and housing etc.The quality of iron core directly affects the open circuit loss and the exciting power of transformer, and amorphous alloy iron core plays critical effect at transformer.
After the amorphous alloy iron core moulding, the annealed processing of magnetizing, iron core open circuit loss and exciting power are descended.General annealing process is undesirable to non-crystaline amorphous metal, and annealing back iron core exciting power is still higher.
Summary of the invention
For addressing the above problem, the invention provides a kind of amorphous alloy transformer core annealing process, make behind the core annealing open circuit loss and exciting power minimum.Core annealing is divided into blow-on, and---La Wen---insulation---cools off four-stage.By my company for a long time to the exploration of core annealing technology and repeatedly trial-production, the iron core holding temperature is determined at 330 ℃-335 ℃, open circuit loss and exciting power are minimum behind the assurance core annealing, are lower than national standard 10%, and the amorphous alloy iron core qualification rate reaches 100%.
Amorphous alloy iron core makes that through exact annealing process the amorphous alloy transformer energy-saving effect of assembling is remarkable, and low, the good economy performance of running cost meets the energy-conservation policy guidance of country.
