Ziziphi izizathu kunye neendlela zokuphatha ukukhubeka kokhuseleko lombane wejeneretha?

Xa sisebenzisa i-generator, sinokuhlangabezana nesiganeko sokukhubeka ngenxa yesenzo sokukhusela umbane. Le yinto eqhelekileyo xa kusetyenziswa iijenereyitha. Kuyimfuneko kakhulu kubasebenzi abasebenzisa kunye nokugcina ijenereyitha ukuba baqonde izizathu zokukhubeka kunye neendlela zokuphatha.

I. Izizathu

1. Ukugqithiswa kwamandla okudlulayo:

- Inkcazo: Ukugqithisa okwethutyana kubhekiselele kwinto ekwinkqubo yamandla yokuba amandla ombane anyuke ngokukhawuleza ngexesha elifutshane ngenxa yezizathu ezinje ngeesekethe ezimfutshane, ukumiswa kwe-arc, ukusebenza kokutshintsha, okanye ukubetha kombane.

- Impembelelo: Ukugqithiswa kombane odlulayo kubeka isoyikiso esibi kwisixokelelwano sokufakelwa kwejeneretha. Inokubangela ukuba ukugquma kwee-windings kuphuke, kwaye emva koko kubangele iisekethe ezimfutshane ze-inter-turn okanye i-inter-phase short circuits. Ukongeza, ukugqithisa okwethutyana kuya kwandisa ilahleko yobushushu yangaphakathi yejenereyitha, okukhokelela ekunyukeni kobushushu obugqithisileyo, kwaye ekugqibeleni kunokubangela ukukhubeka kokhuseleko lombane.

2. Ngokungaphaya:

- Ingcaciso: I-Overcurrent ibhekisa kwisenzeko sokuba umbane wangoku wejeneretha ungaphezulu kwexabiso lawo elilinganisiweyo.

- Izizathu: Utshintsho ngequbuliso kumthwalo, iimpazamo zesekethe emfutshane, okanye ukuhla kwamandla ombane wenkqubo, njl. njl., konke kunokukhokelela ekwenzekeni kwe-overcurrent kwijeneretha.

- Impembelelo: Ukugqithisa kwexesha elide kuya kubangela ukuba i-windings ye-generator igqithise, ikhawuleze ukuguga kwe-insulation, kwaye inokukhokelela ekutshisweni kwee-windings kwiimeko ezinzima. Ngelo xesha, i-overcurrent inokubangela ukwanda kwe-vibration kunye nengxolo ye-generator, echaphazela ukusebenza okuzinzile kwezixhobo.

3. Ukwehla kwamandla ombane:

- Inkcazo: Ukuhla kwamandla ombane kubhekiselele kwinto yokuba inqanaba lombane kwinkqubo yamandla lingaphantsi kunexabiso eliqhelekileyo.

- Izizathu: Ukonyuka komthwalo wenkqubo, ukonyuka kokuphazamiseka komgca, ukungabikho kwamandla asebenzayo, njl. njl., Konke kunokukhokelela ekwehleni kombane.

- Impembelelo: Ukuhla kwamandla ombane kuya kuchaphazela amandla aphumayo kunye nokusebenza kakuhle kwejeneretha. Ngexesha elifanayo, kunokubangela ukuba inkqubo yokuvuselela i-generator ingazinzi, kwaye ibangele ukukhubeka kokukhusela umbane.

II. Phenomena

1. Ukukhubeka kotshintsho oluphambili lwejenereyitha:

- Ukutshatyalaliswa komtshini oyintloko we-generator kukubonakalisa ngokuthe ngqo isenzo sokukhusela umbane, esibonisa ukuba i-generator ikhutshwe kwinkqubo.

2. Ukukhubeka kokutshintsha inkqubo yokuvuselela:

- Ukutshatyalaliswa kokutshintshwa kwenkqubo yokuvuselela ngokuqhelekileyo kwenzeka kunye nokukhubeka kwenguqu ephambili ye-generator, ebonisa ukuba i-generator ilahlekelwe ngumbane othakazelisayo kwaye ayikwazi ukugcina ukusebenza okuqhelekileyo.

3. Iimpawu ezingaqhelekanga zeemitha:

- Izibonakaliso zeemitha ezifana ne-stator yangoku, amandla asebenzayo kunye ne-reactive, i-voltage, kunye ne-frequency ye-generator iya kwehla ngokukhawuleza ukuya kwi-zero okanye isondele kwi-zero.

4. I-alam yesenzo sokhuseleko:

- Isixhobo sokukhusela umbane siya kuthumela iimpawu ezivakalayo nezibonakalayo ze-alamu ukubonisa uhlobo kunye nendawo yesenzo sokukhusela.

5. Iimpawu zangaphandle:

- Kusenokubakho iimpawu zangaphandle ezifana neempembelelo zesixokelelwano, izandi ezingaqhelekanga zejenereyitha, ukwanda kokungcangcazela, ukutshaya, okanye umlilo.

III. Iindlela Zokuphatha

1. Jonga kwaye uqinisekise imeko yokukhubeka:

- Khangela ngokukhawuleza ukuba zonke iimitha zejeneretha zibuyele kwi-zero, kwaye ingaba umtshini oyintloko kunye nokutshintshwa kwe-excitation ye-generator ziye zakhubeka, kwaye uqinisekise ukuba i-generator ikhutshwe ngokukhuselekileyo.

2. Ukubuyisela unikezelo lombane lwenkqubo yenkonzo yesitishi:

- Jonga ukuba isixhobo sokudlulisa ngokukhawuleza senkqubo yenkonzo yesitishi sisebenze ngempumelelo. Ukuba ayisebenzanga okanye ikhubekile emva kotyando, zama ukuyivala ngamandla kube kanye. Ukuba ukuvalwa okunyanzeliswayo akuphumeleli, ungazami ukuvala kwakhona, kwaye ngokukhawuleza uthathe amanyathelo okubuyisela ukunikezelwa kwamandla kwenkqubo yenkonzo yesitishi.

3. Jonga kwaye ujongane nesiphene:

- Ngokwesizathu sokukhubeka kunye nemeko yendawo, khangela kwaye ulinganise i-generator kunye ne-generator-transformer unit system ukumisela ubunjani kunye nobubanzi besiphoso. - Thatha amanyathelo okuphatha ahambelanayo, njengokuhlukanisa indawo yesiphoso, ukubuyisela i-insulation, ukutshintshwa kwezinto ezonakalisiweyo, njl.

4. Buyisela ukusebenza kwesixhobo:

- Emva kokuqinisekisa ukuba impazamo isusiwe kwaye inkqubo izinzile, ngokuthe ngcembe ubuyisele ukusebenza kwejeneretha. Nika ingqalelo ukujonga imeko yokusebenza kwenkqubo yokuvuselela, inkqubo yokulawula isantya, njl., Ukuqinisekisa ukusebenza okuzinzile kwejeneretha.
