Li-relay tsa khase tseo hape li bitsoang li-relay tsa Buchholz li bapala karolo ho li-transformer tse tletseng oli. Li-relay tsena li etselitsoe ho tsebahatsa le ho phahamisa tlhokomeliso ha lipulumo tsa khase kapa tsa moea li fumanoa ka har'a oli ea transformer. Ho ba teng ha li-bubble tsa khase kapa moea ka har'a oli e ka ba pontšo ea bothata ka har'a transformer, joalo ka ho chesa haholo kapa potoloho e khuts'oane. Ka mor'a ho lemoha phoso, mochine oa khase o tla etsa hore ho be le pontšo ho mochine oa potoloho ho khaola le ho sireletsa transformer kotsing. Sengoliloeng sena se sheba hore na ke hobaneng ha li-relay tsa khase li le bohlokoa bakeng sa li-transformer tsa kabo, hore na li sebetsa joang le mefuta ea tsona e fapaneng.
Bohlokoa ba Li-Relay tsa Khase ho Li-Transfer Transformers
Li-transformer ke likarolo tsa marang-rang a motlakase ha li ntse li theola matla a motlakase ho tloha lithapong tsa phetiso ho ea maemong a tšebeliso ea malapa le khoebo. Li-transformer tsena li sebelisa oli joalo ka insulator le ntho e pholileng. Leha ho le joalo liphoso li ka hlaha ka har'a transformer e lebisang ho thehoeng ha bubble ea khase kapa moea ka har'a oli. Li-bubble tsena li ka senya thepa ea insulating ea oli e bakang liphoso le tšenyo ho transformer.
Li-relay tsa khase li etselitsoe ka ho khetheha ho khetholla boteng ba li-bubble tsa khase kapa tsa moea, ka har'a oli ea transformer. Haeba ho na le phoso, relay ea khase e tla bontša hore sekhechana sa potoloho se tsamaea. Tlosa transformer ho grid ea matla ho thibela kotsi leha e le efe ho transformer le ho netefatsa polokeho ea tsamaiso ea matla.
Molao-motheo oa ho Sebetsa oa Liphaello tsa Khase
Li-relay tsa khase li sebetsa ho latela melao-motheo ea ho iphetola ha khase. Ha phoso e kang ho chesa haholo kapa potoloho e khutšoanyane e etsahala ka khase ea transformer e hlahisoa ka oli. Khase ena e nyolohela holimo ka har'a transformer ebe e kena sebakeng sa khase bakeng sa ho bonoa. Sepheo sa relay ena ke ho bona libubble leha e le life tsa khase kapa tsa moea ka har'a oli le ho romela lets'oao ho tsosa sekhechana sa potoloho se arolang transformer ho sistimi ea matla.
Mefuta ea Liphaello tsa Khase
Ho na le mefuta e 'meli ea li-relay tsa khase: relay ea Buchholz le phepelo ea oli.
● Relay ea Buchholz
Buchholz relay (DIN EN 50216-2) ke mofuta o atileng haholo oa phepelo ea khase o sebelisoang ho li-transformer tsa kabo. E reheletsoe ka moqapi oa eona, moenjiniere oa Lejeremane Max Buchholz, ea ileng a qapa relay ka 1921.
Mosebetsi:
Relay ea Buchholz e etselitsoe ho bona ho bokellana ha khase le metsamao e menyane ea oli ka har'a transformer. Haholo-holo e sebelisetsoa ho bona liphoso tse kang ho hloleha ho kenya letsoho, ho chesa haholo, kapa ho lutla ho honyane ho hlahisang khase ka har'a oli ea transformer.
Sebaka:
E kentsoe pompong e kopanyang tanka e kholo ea transfoma ho tanka ea conservator.
Molao-motheo oa ho sebetsa:
Ha khase e hlahisoa ka lebaka la phoso, e ea phahama ebe e kena ho relay ea Buchholz, e tlosa oli le ho etsa hore float e theohe. Sena se kenya tšebetsong switch e romellang lets'oao ho theola sekhechana sa potoloho, se arola transformer.
Tšebeliso:
Hangata e sebelisoa ho li-transformer tsa kabo 'me e sebetsa hantle bakeng sa ho bona liphoso tse ntseng li tsoela pele butle.
● Oil Surge Relay
Mosebetsi:
Phallo ea oli e etselitsoe ho bona liphetoho tsa tšohanyetso phallo ea oli, tse ka supang liphoso tse kholo joalo ka ho lutla ho hoholo kapa li-circuits tse khutšoane tse matla.
Sebaka:
E boetse e behiloe pompong lipakeng tsa tanka ea transformer le tanka ea conservator, empa sepheo sa eona ke ho bona motsamao o potlakileng oa oli ho fapana le ho bokellana ha khase.
Molao-motheo oa ho sebetsa:
Ho phahama ka tšohanyetso ha phallo ea oli ho etsa hore ho phaphametse ka hare ho relay ho sisinyehe, ho etsa hore ho be le sesebelisoa se romelang letšoao ho khopa sephahla sa potoloho, se arola transformer.
Tšebeliso:
Ka tloaelo e sebelisoa ho li-transformer tse kholo moo kotsi ea ho sisinyeha ha oli ka tšohanyetso e leng kholoanyane.
Tsa tsau-tsau
Li-relay tsa khase li bapala karolo ho li-transformer tse tlatsitsoeng ka oli ka ho utloa le ho tsebisa ka likhase kapa libubble tsa moea ka har'a oli ea transfoma. Li-bubble tsena li ka supa litaba, joalo ka li-circuits tse khutšoane. Ka mor'a ho lemoha phoso, relay ea khase e kenya mochine oa potoloho ho arola transformer tsamaisong ea matla e thibelang kotsi. Ho na le mefuta e 'meli ea lisebelisoa tsa khase; Buchholz relay le oli surge relay. Relay ea Buchholz hangata e sebelisoa ho li-transformer ha li-transformer tse kholo li sebelisa phepelo ea oli.
