Hvad er de typer af transformere% 3f

(1) Strøm transformer
At present, representative products that have been in operation in the system include: 1150KV, 1200MV·A, 735-765KV, 800MV·A, 400-500KV, 3-phase 750MV·A or single-phase 550MV·A, 220KV, 3-phase 1300MV·A electric power Transformer; DC transmission ±500KV, 400MV·A converter transformer. Power transformers are mainly oil-immersed, and the product structure is divided into two types: core type and shell type. The production volume of core type accounts for 95 percent , and that of shell type only accounts for 5 percent . There is no overwhelming advantage between the core type and the shell type, but the core type process is relatively simple, so it is adopted by most enterprises; while the shell type structure and process are more complicated, only traditional factories use it. The shell type is especially suitable for high voltage and large capacity. It has advantages in insulation, machinery and heat dissipation, and is suitable for transportation of hydropower stations in mountainous areas.
(2) distribution transformer
Den kapacitet af udenlandske distribution transformere kan nå 2500KV·A, og der er cirkulære og ovale kerneformer. De cirkulære ones rede for det store flertal, og de elliptiske dem kan reducere det materiale forbrug due til de små M0 (den afstand mellem jern kerne søjler), og den tilsvarende spoler er er elliptiske. Lavspændings spoler er er wireviklet og folie, og tanke er er (få) og bølgepap ( de fleste).
(3) tørtype transformer
Recently, dry-type transformers have developed rapidly in China. In big cities such as Beijing, Shanghai and Shenzhen, dry-type transformers have accounted for 50 percent , and in other large and medium-sized cities, they have also accounted for 20 percent . There are four structures of dry change: epoxy resin casting, filling casting, wrapping and impregnation. At present, open and ventilated H-class dry-type transformers are widely used in Europe and the United States. It is a new type of H-class dry transformer developed after absorbing the characteristics of the wrapped structure on the basis of the impregnated type and using Nomex paper. Due to the high price, it is not popular in my country. Not promoted yet. At present, the domestic dry-type distribution transformers with the largest short-circuit test capacity are 2500KV·A, 10/0.4KV; the dry-type power transformers with the largest short-circuit test capacity are 16000KV·A, 35/10KV.
(4) amorf legering transformer
Selvom amorf legering transformere har dårlig kortslutning modstand og høj støj , de er energibesparende% 2c så fremtiden udvikling udsigter er lovende. På nuværende , Kina% 's største amorfe legering transformer kerne producent har en årlig produktion kapacitet af 3% 2c � 3% 2c %7 b% 7 d% 7d tons af jern kerner af jern kerner af transformere er ikke nøglen faktor begrænsende den forfremmelse af amorf legering jern kerne guld transformere. Det gennembrud af amorf legering strimler I rækkefølge til fremme a spring i produkt kvalitet.
(5) Sår kerne transformer
At nuværende, den produktion af viklet kerne transformere er hovedsageligt koncentreret i den 10KV klasse, og den kapacitet er generelt mindre end 800KV·A, og 1600KV·A har også været prøveproduceret, men mest af den elektriske kraft afdelinger indkøb kapacitet under 315KV·A, som er er egnet til landdistrikter strøm net. Der er mere end 200 sår kerne transformer fremstilling anlæg i Kina, 20 procent af hvilken have en bestemt skala. Den produktion kapacitet af stærk spole kerne transformere i Kina er om 16 million KV·A, men den faktiske output er relativt lavt.
