Nau'in Canjin Mai Busasshen Guduro SCB18-2000/10

Dry Transformer wani nau’in wutar lantarki ne wanda ya bambanta da na’urar wutar lantarki da aka nutsar da mai, injin da aka nutsar da mai shi ne amfani da mai na wutan lantarki don rufewa da tarwatsewar zafi, amma abin rufe fuska na busassun transformer galibi shi ne insulation da aka samu ta hanyar zuba resin epoxy.

(1) Tsarin tushen ƙarfe. Ƙarfe na busasshiyar tasfoma shine ɓangaren da'ira na maganadisu, wanda ya ƙunshi sassa biyu: ginshiƙin ƙarfe na ƙarfe da kuma karkiya na ƙarfe. An tattara iskar a kan babban ginshiƙi, kuma ana amfani da karkiya don rufe duk da'irar maganadisu. Gabaɗaya za a iya raba tsarin jigon cikin gida biyu: nau'in asali da nau'in harsashi. Jigon yana da karkiyar ƙarfe akan sama da ƙasa na iskar, amma baya kewaye gefen iskar; Shell core yana da karkiyar ƙarfe wanda ke kewaye ba kawai saman da kasa na iskar ba, har ma da bangarorin da ke cikin iska. Saboda tsarin ginin yana da sauki, kuma shimfidar iskar gas da insulation suma suna da kyau sosai, don haka busassun tafanfoma na kasar Sin galibi suna amfani ne da core, sai kawai a wasu busassun na'urorin lantarki na musamman (irin su bushewar tanderun lantarki) don amfani da harsashi.

(2) Iron core material. Domin ginshiƙin ƙarfe shine da'irar maganadisu na busassun na'ura mai canzawa, kayansa yana buƙatar haɓakar ƙarfin maganadisu mai kyau, kuma ƙarfin maganadisu mai kyau ne kawai zai iya sa asarar ƙarfe ta yi ƙanƙanta. Saboda haka, baƙin ƙarfe core na busassun gidan wuta da aka yi da silicon karfe takardar. Akwai nau'i biyu na siliki karfe sheet: zafi birgima da sanyi birgima karfe sheet. Saboda sanyi-birgima karfe takardar yana da mafi girma permeability da karami naúrar asarar lokacin da magnetizing tare da mirgina shugabanci, da yi shi ne mafi alhẽri daga na zafi-birgima karfe takardar, da kuma gida busassun gidajen wuta duk amfani sanyi-birgima karfe takardar silicon karfe takardar. Kauri na gida sanyi birgima karfe takardar ne 0.35, 0.30, 0.27mm da sauransu. Idan takardar tana da kauri, hasarar eddy a halin yanzu tana da girma, kuma idan takardar ta kasance sirara, ƙimar lamination ɗin ƙarami ne, saboda saman takardar silicon karfe dole ne a lulluɓe shi da fenti mai rufi don rufe takardar daga yanki ɗaya. zuwa wani.

Iskar shine sashin da'irar busasshen taswira, wanda gabaɗaya ana yin shi da insulated enameled, nannade takarda da aluminum ko wayar tagulla.

Dangane da tsari daban-daban na iska mai ƙarfi da ƙarancin wutar lantarki, za a iya raba windings zuwa concentric da rhomboid. Don haɗakarwa mai mahimmanci, don sauƙaƙe rufin tsakanin iska da mahimmanci, ƙananan ƙarfin wutar lantarki yawanci ana sanya shi kusa da ginshiƙi mai mahimmanci: don overlapping windings. Don rage nisa mai rufewa, ƙarancin wutar lantarki yawanci ana sanya shi kusa da karkiya.

Babban kayan da ke rufe busassun taranfoma su ne busasshen man tasfoma, kwali mai rufe fuska, takardan igiya, takarda gyale da sauransu.

Domin samar da barga irin ƙarfin lantarki, sarrafa iko kwarara ko daidaita load juriya halin yanzu, shi wajibi ne don daidaita irin ƙarfin lantarki na bushe transformer. A halin yanzu, hanyar daidaita wutar lantarki ta injin taswirar busasshen ita ce saita famfo a gefe ɗaya na iska don yanke ko ƙara wani ɓangaren jujjuyawar don canza adadin jujjuyawar, ta yadda za a cimma hanyar. daidaita ƙarfin lantarki mai daraja ta canza yanayin ƙarfin lantarki. Da'irar da ake zana iskar da kuma dannawa don daidaita wutar lantarki ana kiranta da'irar ka'ida; Maɓallin da aka yi amfani da shi don canza famfo don daidaita matsa lamba ana kiransa maɓallin tap. Gabaɗaya, mataki na gaba shine zana fam ɗin da ya dace akan babban iskar wutar lantarki. Wannan shi ne saboda yawancin ƙarfin wutar lantarki ana saita shi a waje, wanda zai kai ga famfo ya dace, na biyu, babban ƙarfin wutar lantarki na gefen halin yanzu karami ne, na yanzu yana ɗauke da sashin gubar famfo da mai canza famfo ƙarami ne, kuma haɗin kai tsaye na sauya kuma ya fi yiwuwa a kera shi.

Ƙa'idar ƙarfin lantarki na gefen sakandare na busassun gidan wuta ba tare da juriya ba, kuma ɓangaren farko kuma an katse shi daga grid na wutar lantarki (babu ƙarfin wutar lantarki), ana kiransa tsarin wutar lantarki ba tare da tashin hankali ba, da kuma tsarin wutar lantarki tare da juriya ga juriya don juyawa juyawa. bugawa.
