Chiyero chekushandiswa kweakangwara arc kudzvinyirira mudziyo:
1. Ichi chishandiso chakakodzera 3 ~ 35KV yepakati voltage simba system;
2. Iyi midziyo inokodzera hurongwa hwekugovera simba apo nzvimbo isina kusimba haina kudzika pasi, nzvimbo isina kusimba inodzika pasi kuburikidza nearc kudzvinyirira coil, kana kuti nzvimbo isina zvematongerwo enyika inotarirwa kuburikidza nekupikisa kwepamusoro.
3. Iyi midziyo yakakodzera magetsi emagetsi ane tambo semuviri mukuru, hybrid power grids ane tambo uye tambo dzepamusoro semuviri mukuru, uye magetsi ane tambo dzepamusoro semuviri mukuru.
Basic mabasa ehungwaru arc kudzvinyirira michina:
1. Kana chigadzirwa chacho chiri mukushanda kwakajairika, ine basa rePT cabinet
2. Panguva imwecheteyo, ine basa rekugadzirisa system alarm uye kuvhara;
3. System metal ground fault alarm, transfer system ground fault point basa;
4. Bvisa arc grounding device, iyo system software series resonance function;iyo yepasi voltage uye overvoltage alarm basa;
5. Iine ruzivo rwekurekodha mabasa akadai searm alarm yekubvisa nguva, kukanganisa kwechimiro, kukanganisa kwechikamu, system voltage, open circuit delta voltage, capacitor pasi ikozvino, nezvimwewo, izvo zviri nyore pakugadzirisa kukanganisa uye kuongorora;
6. Kana iyo system software ine imwechete-phase grounding kukanganisa, mudziyo unogona pakarepo kubatanidza kukanganisa pasi mukati meinenge 30ms kuburikidza nechikamu chakakosha-kupatsanura vacuum contactor.The grounding overvoltage yakagadzikana pachikamu chevoltage level, iyo inogona kunyatso kudzivirira maviri-mavara mapfupi edunhu kukanganisa kunokonzerwa ne-single-phase grounding uye zinc oxide arrester kuputika kunokonzerwa nearc grounding overvoltage.
7. Kana iyo simbi yakadzika, iyo yekusangana voltage uye nhanho voltage inogona kuderedzwa zvakanyanya, iyo inobatsira pakuchengetedza kuchengetedzwa kwemunhu (metal grounding inogona kuiswa kana mudziyo unoshanda zvinoenderana nemushandisi zvinodiwa);
8. Kana yakashandiswa mugetsi remagetsi rinonyanya kuumbwa nemitsara yekumusoro, vacuum contactor inovhara yega mushure memasekondi mashanu ekushanda kwechigadzirwa.Kana iko kutadza kwechinguvana, system yacho inodzokera kune yakajairika.Muchiitiko chekukundikana zvachose, chigadzirwa chichashanda zvakare kuti chigadzirise zvachose overvoltage.
9. Kana kukanganisa kwe PT kuchiitika muhurongwa, chigadziro chicharatidza mutsauko wechikamu chekukanganisa kwekubvisa uye kuburitsa chiratidzo chekubatana panguva imwe chete, kuitira kuti mushandisi anogona kuvharira zvakavimbika mudziyo wekudzivirira unogona kutadza nekuda kwePT kubviswa. .
10. Chigadzirwa chacho chakasiyana-siyana che "intelligent socket (PTK)" tekinoroji inogona kudzvanya zvakanyanya kuitika kweferromagnetic resonance, uye kudzivirira zvinobudirira platinum kubva pakupisa, kuputika uye dzimwe tsaona dzinokonzerwa nesystem resonance.
11. Chigadzirwa chacho chine RS485 socket, uye inotora mitemo yeMODBUS yekukurukurirana kuti ive nechokwadi chekuenderana pakati pemudziyo nemavhidhiyo ose ekuongorora maitiro, uye kuchengetedza mabasa ekufambisa data uye kure kure.
Mirayiridzo yekuraira yakangwara arc kudzvinyirira mudziyo
(1) Mutengi anofanirwa kupa iyo yakakodzera yakatemerwa voltage yeiyo sisitimu uye yakakwira ikozvino yeimwe-chikamu chekudzika capacitor cheiyo system sehwaro hwekugadzira michina;
(2) Saizi yekabati inogona chete kupedzwa mushure mekugadzira mainjiniya edu uye nekusimbisa nesaini yemushandisi.
(3) Mutengi anofanirwa kuona mashandisirwo emidziyo (kusanganisira zvakakosha zvinhu uye mamwe mabasa), kusaina inoenderana tekinoroji chirongwa, uye nekuisa pachena zvese zvakakosha zvinodiwa paunenge uchitenga.
(4) Kana zvimwe zvishongedzo zvekuwedzera kana zvikamu zvakasara zvichidikanwa, zita, kutsanangurwa uye huwandu hwezvinhu zvinodikanwa zvinofanirwa kuratidzwa pakurodha.
