Ihe Mgbanwe Mgbata Transformer

Ngwaọrụ nhazi voltaji nke transformer ahụ kewara n'ime ngwaọrụ nhazi voltaji "off-excitation" nke transformer na onye na-agbanwe tap "on-load".

Ha abụọ na-ezo aka na ụdị nhazi voltaji nke onye na-agbanwe tap transformer, yabụ kedu ihe dị iche n'etiti ha abụọ?

① Ihe mgbanwe ọkpọkọ "anaghị akpali akpali" bụ ịgbanwe ọkpọkọ akụkụ voltaji dị elu nke transformer iji gbanwee oke ntụgharị nke winding maka nhazi voltaji mgbe ma akụkụ mbụ na nke abụọ nke transformer ahụ kwụsịrị na ọkọnọ ike.

② "N'elu-ibu" tap changer: Site na iji ihe mgbanwe tap canver nke na-ebu ibu, a na-agbanwe tap nke transformer winding iji gbanwee mgbanwe voltaji dị elu maka nhazi voltaji na-enweghị ibelata ọkụ eletrik.

Ihe dị iche n'etiti ha abụọ bụ na ihe na-agbanwe tap off-excitation enweghị ike ịgbanwe gia na ibu, n'ihi na ụdị ihe na-agbanwe tap a nwere usoro nkwụsịtụ nwa oge n'oge usoro mgbanwe gia. Ịkwụsị ọkụ eletrik ibu ga-eme ka arcing dị n'etiti kọntaktị ma mebie ihe na-agbanwe tap. Ihe na-agbanwe tap load nwere mgbanwe nguzogide gabigara ókè n'oge usoro mgbanwe gia, yabụ enweghị usoro nkwụsịtụ nwa oge. Mgbe ị na-agbanwe site na otu gia gaa na nke ọzọ, enweghị usoro arcing mgbe a kwụsịrị ọkụ eletrik ibu. A na-ejikarị ya eme ihe maka transformers nwere ihe achọrọ voltaji siri ike nke kwesịrị ka a na-agbanwekarị.

Ebe ọ bụ na onye na-agbanwe tap transformer "on-load" nwere ike ịrụ ọrụ nhazi voltaji n'okpuru ọnọdụ ọrụ nke transformer, gịnị kpatara ị ga-eji họrọ onye na-agbanwe tap "off-load"? N'ezie, ihe mbụ kpatara ya bụ ọnụahịa ya. N'ọnọdụ nkịtị, ọnụahịa nke onye na-ewepụ ibu ahụ nwere ike ịrụ ọrụ Mgbata Mgbanwe Transformer bụ 2/3 nke ọnụahịa nke transformer mgbanwe tap na-ebu ibu; n'otu oge ahụ, olu nke transformer mgbanwe tap na-ebu ibu dị obere nke ukwuu n'ihi na ọ nweghị akụkụ mgbanwe tap na-ebu ibu. Ya mere, na-enweghị iwu ma ọ bụ ọnọdụ ndị ọzọ, a ga-ahọrọ transformer mgbanwe tap na-ebu ibu.

Gịnị mere ị ga-eji họrọ ihe na-agbanwe tap transformer? Gịnị bụ ọrụ ya?
① Meziwanye ọnụego ikike voltaji.
Nnyefe ike na netwọk nkesa sistemụ ike na-akpata mfu, uru mfu ahụ bụkwa nke kacha nta naanị nso voltaji enyere ikike. Ime iwu voltaji n'elu ibu, ịnọgide na-enwe voltaji bọs substation mgbe niile, na ime ka akụrụngwa eletriki na-arụ ọrụ na steeti voltaji enyere ikike ga-ebelata mfu ahụ, nke bụ nke kachasị mma ma dị mma. Ọnụego asambodo voltaji bụ otu n'ime ihe ngosi dị mkpa nke ịdị mma nke ọkọnọ ike. Nhazi voltaji n'oge nwere ike hụ na ọnụego asambodo voltaji, si otú a na-emezu mkpa nke ndụ ndị mmadụ na mmepụta ụlọ ọrụ mmepụta ihe na ugbo.

② Meziwanye ikike nkwụghachi ike mmeghachi omume ma mee ka ọnụego ntinye nke capacitor dịkwuo elu.
Dịka ngwaọrụ nkwụghachi ike mmeghachi omume, mmepụta ike mmeghachi omume nke capacitors ike kwekọrọ na square nke voltaji ọrụ. Mgbe voltaji ọrụ nke sistemụ ike belatara, mmetụta nkwụghachi ụgwọ na-ebelata, na mgbe voltaji ọrụ na-abawanye, a na-akwụghachi akụrụngwa eletriki gabiga ókè, na-eme ka voltaji njedebe na-abawanye, ọbụna gafere ọkọlọtọ, nke dị mfe imebi mkpuchi nke akụrụngwa na ihe kpatara ya.
ihe mberede akụrụngwa. Iji gbochie ike mmeghachi omume ịlaghachi na sistemụ ike na akụrụngwa nkwụghachi ike mmeghachi omume ka ọ ghara ịrụ ọrụ, nke na-ebute mfu na mmụba nke ngwaọrụ ike mmeghachi omume, a ga-agbanwe ihe mgbanyụ ọkụ isi transformer n'oge iji gbanwee voltaji bọs ahụ ka ọ bụrụ oke ruru eru, ka ọ gharakwa ịdị mkpa ịgbanyụ ụgwọ capacitor.

Kedu otu esi arụ ọrụ iwu voltaji n'elu ibu?
Usoro nhazi voltaji n'elu ibu gụnyere iwu voltaji eletrik na iwu voltaji aka.

Isi ihe dị mkpa n'ịhazi voltaji n'elu ibu bụ ịgbanwe voltaji site n'ịhazi oke mgbanwe nke akụkụ voltaji dị elu ebe voltaji dị n'akụkụ voltaji dị ala anaghị agbanwe agbanwe. Anyị niile maara na akụkụ voltaji dị elu bụkarị voltaji sistemụ, voltaji sistemụ na-agbanwekarị agbanwe. Mgbe ọnụọgụgụ nke ntụgharị na winding akụkụ voltaji dị elu mụbara (ya bụ, a mụbara oke mgbanwe), voltaji dị n'akụkụ voltaji dị ala ga-ebelata; kama nke ahụ, mgbe ọnụọgụgụ ntụgharị na winding akụkụ voltaji dị elu belatara (ya bụ, a belatara oke mgbanwe), voltaji dị n'akụkụ voltaji dị ala ga-abawanye. Nke ahụ bụ:

Mmụba ntụgharị = mgbanwe mgbada = mbelata voltaji Mbelata ntụgharị = mgbanwe elu = mmụba voltaji
Ya mere, n'ọnọdụ dị aṅaa ka transformer agaghị arụ ọrụ na-ebu ibu tap changer?
① Mgbe transformer ahụ buru ibu (ma e wezụga maka ọnọdụ pụrụ iche)
② Mgbe etinyere mkpu ọkụ gas nke ngwaọrụ njikwa voltaji n'elu ibu
③ Mgbe nguzogide nrụgide mmanụ nke ngwaọrụ njikwa voltaji dị n'elu erughị eru ma ọ bụ enweghị mmanụ na akara mmanụ
④ Mgbe ọnụọgụgụ iwu voltaji gafere ọnụọgụ akọwapụtara
⑤ Mgbe ngwaọrụ njikwa voltaji adịghị mma

Gịnị mere oke ibu ji akpọchikwa ihe na-agbanwe tap?
Nke a bụ n'ihi na n'ọnọdụ nkịtị, n'oge usoro nhazi voltaji n'elu ibu nke transformer bụ isi, enwere ọdịiche voltaji n'etiti njikọ isi na tap ebumnuche, nke na-emepụta ọkụ eletrik na-agagharị agagharị. Ya mere, n'oge usoro nhazi voltaji, a na-ejikọ resistor n'otu akụkụ iji gafee ọkụ eletrik na ọkụ eletrik na-agagharị agagharị. Resistor parallel kwesịrị iguzogide ọkụ eletrik buru ibu.

Mgbe transformer ike ahụ buru ibu, ọkụ eletrik nke transformer isi na-arụ ọrụ karịrị ọkụ eletrik nke onye na-agbanwe tap, nke nwere ike ịgba njikọ enyemaka nke onye na-agbanwe tap ahụ ọkụ.

Ya mere, iji gbochie ihe na-eme ka ihe na-agbanwe tap gbanwee, a machibidoro iwu ịchịkwa voltaji n'elu ibu mgbe transformer bụ isi karịrị akarị. Ọ bụrụ na a manye iwu voltaji, ngwaọrụ nhazi voltaji n'elu ibu nwere ike ịgba ọkụ, gas ibu nwere ike ịgbalite, ma gbanwee isi transformer ahụ nwere ike ịda ada.
