Gasi relays inonziwo Buchholz relays inoita basa mumafuta akazara ekugovera matransformer. Aya madhiri akagadzirirwa chaizvo kuona uye kusimudza yambiro kana gasi kana mabhuru emhepo aonekwa mumafuta etransformer. Kuvapo kwegasi kana mhepo inoputika mumafuta inogona kuva chiratidzo chechinetso mukati memushanduri, zvakadai sekupisa kana kuti pfupi pfupi. Pakuona kukanganisa gasi relay inokonzeresa chiratidzo kune wedunhu breaker kuti ibvise uye kudzivirira iyo transformer kubva mukukuvadza. Chinyorwa ichi chinotarisa kuti sei gasi relay rakakosha pakugovera matransformer, mashandisiro avanoita uye nemhando dzavo dzakasiyana.
Kukosha kweGasi Relays muDistribution Transformers
Distribution transformers zvikamu zve network yemagetsi pavanenge vachidzika magetsi emagetsi kubva kumatanho ekutakurisa kuenda kumatanho ekushandiswa kwemba nekutengesa. Aya ma transformer anoshandisa oiri sese insulator uye inotonhorera mumiriri. Nekudaro zvikanganiso zvinogona kusimuka mukati meiyo transformer inotungamira kune gasi kana mweya bubble kuumbwa muoiri. Aya mabhuru anogona kukanganisa iyo insulating zvivakwa zveoiri zvichikonzera kukanganisa uye kukanganisa kune transformer.
Gasi relays dzakagadzirirwa chaizvo kuona kuvepo kwegasi kana mabhuru emhepo, mumafuta etransformer. Kana paine chikanganiso gasi relay rinoratidza kuti mupazaki wedunhu afambe. Bvisai transformer kubva kune gidhi remagetsi kudzivirira chero kukuvadza kune transformer uye kuve nechokwadi chekuchengetedzwa kwesimba remagetsi.
Kushanda Nheyo yeGasi Relays
Gasi relays inoshanda zvichibva pane gasi shanduko yemisimboti. Kana kukanganisa kwakafanana nekupisa kana kupfupika kunoitika mugasi rekushandura rinogadzirwa mumafuta. Iri gasi rinokwira kumusoro mukati me transformer uye rinopinda mugasi relay kuti rionekwe. Chinangwa cheiyi relay ndechekuona chero gasi kana mabubbles emhepo muoiri uye kutumira chiratidzo kukonzeresa dunhu rinotyora rinoparadzanisa transformer kubva kune simba system.
Mhando dzeGasi Relays
Kune marudzi maviri egasi relay: iyo Buchholz relay uye mafuta ekuvhiya relay.
●Buchholz Relay
Iyo Buchholz relay (DIN EN 50216-2) ndiyo yakajairika rudzi rwegasi relay rinoshandiswa mukugovera matransformer. Yakatumidzwa zita remugadziri wayo, injinjini yeGerman Max Buchholz, akagadzira relay muna 1921.
Basa:
Iyo Buchholz relay yakagadzirirwa kuona kuunganidzwa kwegasi uye madiki emafuta ekufamba mukati meshanduko. Inonyanya kushandiswa kuona zvikanganiso zvakadai sekutadza kwekudzivirira, kupisa, kana kudonha kudiki kunoburitsa gasi mukati memafuta etransformer.
Nzvimbo:
Yakaiswa mupombi inobatanidza main transformer tank kune conservator tank.
Working Principle:
Kana gasi ragadzirwa nekuda kwekukanganisa, inosimuka ichipinda muBuchholz relay, ichibvisa oiri uye ichikonzera kudonha kudonha. Izvi zvinomisikidza switch inotumira chiratidzo kuti ifambise wedunhu breaker, ichiparadzanisa transformer.
Kushandisa:
Inowanzo shandiswa mukugovera shandurudzo uye inoshanda pakuona kunonoka-kukura kukanganisa.
●Oil Surge Relay
Basa:
Oiri yekuvhiya relay yakagadzirirwa kuona shanduko dzinongoerekana dzaitika mukuyerera kwemafuta, izvo zvinogona kuratidza kukanganisa kukuru senge mavuza makuru kana mapfupi mapfupi.
Nzvimbo:
Inoiswawo mupombi pakati petransformer tank uye tangi inochengetedza, asi yakatarisana nekuona kukurumidza kufamba kwemafuta kwete kuunganidzwa kwegasi.
Working Principle:
Kamwe kamwe kuputika kwekuyerera kwemafuta kunokonzera kutenderera mukati meiyo relay kufamba, zvichikonzera switch inotumira chiratidzo kutsika dunhu rinotyora, ichiparadzanisa transformer.
Kushandisa:
Inowanzo shandiswa mune makuru matransformer uko njodzi yekukurumidza kufamba kwemafuta yakakura.
Tora woenda nazvo
Gasi relays rinoita basa muoiri yakazadzwa kugovera ma transformer nekuona uye kuzivisa nezve gasi kana mabhuru emhepo mumafuta etransformer. Aya mabhuru anogona kuratidza nyaya, semapfupi maseketi. Pakuonekwa kwemhosho, gasi relay rinoita kuti muparadzi wedunhu aparadzanise transformer kubva kumagetsi system kudzivirira kukuvadza. Kune marudzi maviri egasi relay; Buchholz relay uye mafuta ekuvhiya relay. Iyo Buchholz relay inowanzo shandiswa mukugovera matransformer ukuwo ma transformer makuru anoshandisa mafuta ekuvhiya relay.
