6-220kV high voltage Current Limited reactor
Chii chinonzi Current limiting reactor
Ikozvino inomisa mareactor chinhu inductive chikamu chinodzikamisa switching inrush ikozvino, yakakwirira-yakarongeka harmonic uye pfupi-yedunhu kukanganisa ikozvino muhurongwa. Azvino anomisa mareactor anogadzirwa nemhangura kana aluminium coil. Nzira dzekutonhodza dzinosanganisira Air Core yakaoma mhando uye mafuta kunyudza mhando.
Kazhinji inoshandiswa pakugovera mitsetse. Iwo mafeedi ebazi kubva kubhazi rimwe chete anowanzo kubatanidzwa neinogumira ikozvino reactor kudzikamisa pfupi-yedunhu ikozvino yeanodyisa uye kuchengetedza iyo bhazi voltage, kuti irege kuderera zvakanyanya nekuda kwepfupi-dunhu reiyo feeder.

Mashandisiro anoita Current limiting reactors anoshanda
Azvino anomisa mareactor anoshandiswa mugiredhi yemagetsi ndeye Mhepo coil isina magineti inoitisa zvinhu. Inogona kurongwa mumhando nhatu dzegungano: vertical, horizontal uye zigzag. Kana dunhu diki rikaitika musimba remagetsi, kukosha kukuru kweiyo pfupi yedunhu ikozvino inogadzirwa. Izvo zvakanyanya kuoma kuchengetedza kusimba kwakasimba uye kugadzikana kwekushisa kwemidziyo yemagetsi pasina kurambidzwa. Naizvozvo, kuti zvizadzise zvinodikanwa zvekupaza kugona kwevamwe vanopwanya dunhu, mareji emagetsi anowanzo kubatanidzwa munhevedzano kune anobuda edunhu mabreaker kuti awedzere kupfupi-wedunhu impedance uye kudzikamisa pfupi-yedunhu ikozvino.
Nekuda kwekushandiswa kwereactor, kana iri pfupi reketi, kudonha kwevoltage paIrizvino inomisa mareactor yakakura, saka inoitawo basa mukuchengetedza bhazi voltage level, kuitira kuti kushanduka kwemagetsi mubhazi kuve kudiki, kuve nechokwadi chekushanda. kugadzikana kwemidziyo yemagetsi yemushandisi pane isina kukanganisa.
Kuverenga uye kugadzirisa kwehuwandu
Iyo yekuverenga fomula yesimba rereactor ndeiyi: SN = UD% X (kumusoro / √ 3) x In, uye chikamu chemukati ndeye Ampere.

Ndeipi nzvimbo inoshandisa Current-limiting reactors
Chinangwa chekuisa Current-limiting reactors mumagetsi emagetsi uye substations ndechekudzikamisa pfupi-circuit current kuitira kuti midziyo yemagetsi isarudzwe pahupfumi uye zvine musoro. Mareactor anogona kupatsanurwa kuita mitsara reactor, mabhazi reactor, uye transformer loop reactor zvinoenderana nenzvimbo dzakasiyana dzekuisa uye mabasa.
(1) Line reactor. Kuti ushandise mwenje wedunhu rekutyora uye kuderedza chikamu chemuchinjiko weiyo feeder tambo, iyo mutsara reactor inowanzobatanidzwa munhevedzano kune tambo feeder.
(2) Bhazi reactor. Iyo bhazi reactor yakabatana munhevedzano pachikamu chejenareta voltage bhazi kana yakaderera-voltage divi reiyo main transformer. Inoshandiswa kudzikamisa iyo pfupi-yedunhu ikozvino panguva pfupi-madunhu mukati nekunze kwechirimwa. Inonziwo bhazi chikamu reactor. Kana dunhu diki rikaitika pamutsetse kana pane rimwe bhazi, rinogona kudzikamisa pfupi-dunhu ikozvino rinopihwa nerimwe bhazi. Kana izvo zvinodikanwa zvichigona kuzadzikiswa, kuisirwa reactor pamutsara wega wega kunogona kusiiwa kuchengetedza mainjiniya ekudyara, asi ine diki mhedzisiro yekumisa pfupi-yedunhu ikozvino.
(3) Transformer loop reactor. Inoiswa mushanduro yedunhu kuti igadzirise iyo pfupi-yedunhu ikozvino kuitira kuti transformer redunhu rinogona kushandisa chiedza chemagetsi.
Ndezvipi zvakanakira Current limiting reactors
1. Mhepo inogadzirwa nematareji maduku akawanda akaenzana uye tambo dzakawanda, uye inter-turn insulation simba yakakwirira, saka kurasikirwa kwakanyanya kuderera kupfuura iyo simenti reactor;
2. Adopt epoxy resin-impregnated glass fiber encapsulation, uye kusimba pakupisa kwepamusoro, saka ine kuvimbika kwakasimba, huremu huremu, ruzha rushoma, simba remagetsi, uye inogona kumira kukanganiswa kwehombe pfupi-circuit current.
3. Kune nzira dzekufambisa mhepo pakati pezvikamu zvemhepo, iyo convection yakasikwa yekutonhora kushanda yakanaka, uye ikozvino inogoverwa zvakaenzana mumutsara wega wega, uye kusimba uye kugadzikana kwekushisa kwakakwirira;
4. Nzvimbo yekunze yereactor yakaputirwa ne-anti-ultraviolet weather-resistant resin coating, iyo inogona kumira nemamiriro okunze akaoma kunze, uye inogona kushandiswa mukati uye kunze.
