Tap shanduko midziyo inogona kuwedzera kana kuderedza inobuda yechipiri voltage nekushandura reshiyo yekutendeuka yepuraimari kana yechipiri mhepo. Chinja chepombi chinowanzoiswa pane yakakwira voltage chikamu cheaviri-inotenderera transformer, nekuda kweiyo yakaderera ikozvino munzvimbo iyoyo. Vashanduri vanopihwawo pamhepo yakakwira voltage windings yemagetsi emagetsi kana paine zvakakwana kutonga kwemagetsi. Shanduko yevoltage inokanganiswa kana iwe uchichinja huwandu hwekutendeuka kwetransformer yakapihwa matepi.
Kune marudzi maviri eTap Changers:
1. On-Load Tap Changer
Chinhu chayo chikuru ndechekuti panguva yekushanda, dunhu guru rekushandura harifaniri kuvhurwa. Izvi zvinoreva kuti hapana chikamu chekuchinja chinofanira kuwana pfupi pfupi. Nekuda kwekuwedzera uye kubatana kwesimba remagetsi, zvinova zvakakosha kuti uchinje matepi ekushandura kakawanda zuva rega rega kuti uwane iyo voltage inodiwa sekuenderana nezvinodiwa.
Uku kudiwa kwekuenderera mberi kwekupa hakukubvumidze kuti ubvise dhizaini kubva kune sisitimu yekubvisa-kuremedza tap kuchinja. Nekudaro, on-load tap ekuchinja anofarirwa mune mazhinji emagetsi emagetsi.
Mamiriro maviri anofanirwa kuzadzikiswa paunenge uchibaya:
· Yekuremerwa yedunhu inofanirwa kuve yakasimba kudzivirira kuvharidzira uye kudzivirira kusangana kukuvara
·Paunenge uchigadzirisa pombi, hapana chikamu chemhepo chinotenderedza chinofanira kunge chiri chipfupi-chinotenderera
Mumufananidzo uri pamusoro, S ndiyo diverter switch, uye 1, 2 uye 3 ndiyo inosarudzika switch. Iyo pombi inochinja inoshandisa iyo yepakati yakatepwa reactor R sezvakaratidzwa mudhayagiramu. Iyo transformer inoshanda kana switch 1 uye S yakavharwa.
Kuti uchinje ku tap 2, switch S inofanira kuvhurwa uye switch 2 inofanira kuvharwa. Kupedzisa shanduko yepombi, switch 1 inoshanda uye switch S yakavharwa. Rangarira kuti diverter switch inoshanda pa-load uye hapana ikozvino inoyerera mune yekusarudza switch panguva yekuchinja tepi. Kana iwe uchibaya shanduko, hafu chete yekuita iyo inomisa ikozvino yakabatana mudunhu.
2.Off-Load/No-load Tap Changer
Iwe unofanirwa kuisa shanduko ye-off-load pane transformer kana shanduko inodiwa mumagetsi isingawanzo. Iwo matepi anogona kuchinjwa mushure mekuparadzanisa zvachose transformer kubva kudunhu. Rudzi urwu rwekuchinja runowanzo kuisirwa pane yekugovera transformer.
Kuchinja kwepombi kunogona kuitwa kana transformer iri muOff-Load kana No-Load mamiriro. Mune yakaoma-mhando transformer, chiitiko chinotonhora chinoitika kunyanya nemhepo yakasikwa. Kusiyana ne-on-load tap kuchinja uko kudzima kwearc kunogumira nemafuta kana transformer iri-kuremerwa, kubaya ne-off-load tap shanduko inongoitwa kana transformer iri mu OFF-Switch mamiriro.
Inowanzo shandiswa mumamiriro ezvinhu apo kutendeuka-reshiyo haifaniri kuchinjwa zvakanyanya, uye de-energizing inobvumirwa mumagetsi mashoma uye pasi-voltage transformers. Mune mamwe, kuchinja kwepombi kunogona kuitwa ne rotary kana slider switch. Inogona kunyanya kuonekwa mumapurojekiti emagetsi ezuva.
Off-load tap ekuchinja anoshandiswawo mune yakakwira voltage transformers. Iyo sisitimu yevashanduri vakadaro inosanganisira isina-mutoro wepombi shanduko pane yekutanga mhepo. Shanduko iyi inobatsira kugadzirisa misiyano mukati mebhendi nhete yakatenderedza chiyero chezita. Mune masisitimu akadai, iyo pombi inoshandura inowanzoitwa kamwe chete, panguva yekuiswa. Nekudaro, inogona zvakare kuchinjwa panguva yakarongwa yekudzima kugadzirisa chero shanduko yenguva refu muiyo system voltage profile.
Izvo zvakakosha kuti iwe usarudze iyo chaiyo mhando yetap shanduko zvichienderana nezvaunoda.
