What aspects does the quality of epoxy cast resin dry type transformers depend on?
(1) Energy saving and low noise: Low loss silicon steel sheet, stepped iron joints, foil winding structure, and in-depth research on environmental protection requires computer optimization design and other new materials, new processes, and new technologies to be introduced and developed to make wet-type transformers More energy-saving and quieter than simply relying on material input to reduce iron loss or copper loss
(2) High reliability: The operational reliability of electrical products, especially transformers, is particularly important. The electromagnetic field theory and its calculation, wave path, casting process, hot spot temperature rise, partial discharge mechanism, quality assurance system, reliability engineering and other aspects are actively researched on quantitative basis. Carry out reliability certification and progress, improve the reliability of epoxy cast resin dry type transformers, and pursue unremittingly
(3) Environmental protection characteristics certification: European standard HD464 basic exhibition dry-type transformer weather resistance (C0, C1, C2), environment resistance (E0, E1, E2), fire resistance (F0, F1, F2) characteristics research and certification
(4) Capacity: The capacity of the distribution transformer is 2,500KVA. At present, the dry-type transformers are developed and produced by the main owners of the dry-type transformers. Power supply dry-type power transformers have been widely used has produced nearly ten sets of 35KV 16,000/24,000KVA ultra-capacity dry transformers
(5) Function combination and intelligence: The single transformer with substation function is developed into a combined transformer with functions such as forced air cooling, protective casing, power metering, computer interface, closed busbar, various low-voltage lateral lines, etc.; the introduction of TTU intelligence The interface has the functions of data processing, status control, status display, etc., so that the transformer functions are intelligent, and the electrical equipment is in the best operating state. epoxy cast resin dry type transformer
(6) Field development: Distribution transformers are mainly used in power plant excitation transformers, factory transformers, rail transit traction rectifier transformers, current electric furnace transformers, nuclear power plants, marine applications, oil extraction platforms and other special transformers and applications. Recently, Shunte Electric has developed R&D and mass production of special products in various fields
(7) Materials and varieties: Our epoxy cast resin dry type transformer occupies the leading market. It is expected that it will be difficult to change in the near future. The dry-type transformer has excellent performance and its performance indicators reach the international advanced level. Low moisture-proof performance, 100% humidity operation, shutdown operation, after pre-drying, it is put into operation loss, low partial discharge, strong noise and heat dissipation capacity, mechanical performance, strong short-circuit resistance, and high-voltage winding. Winding and casting in vacuum state and equipped with perfect temperature protection and control system for safe operation of transformers
