XHQ5 uchungechunge 10KV 5KA Outdoor High voltage Overhead insulated umugqa overvoltage umvikeli
Incazelo Yomkhiqizo
Njengoba izinga lokufakelwa kwemigqa ye-10KV ngokuvamile liphansi, kunzima ukumelana nemiphumela yombani oqondile noma umbani wokungenisa.Uma iphezulu kakhulu, izophinde ibangele i-flashover, ungqimba lokufakelwa luzophulwa, i-arc yamandla aqhubekayo azoshisa lapha, futhi ucingo luzoshaywa ngesikhathi esifushane kakhulu.
Isivikeli se-overvoltage yomugqa sisho okokusebenza kokuvikela imigqa yokuphakama okuphezulu.Ukweqisa kombani okuqondile noma ukukhuphuka kombani okudalwe ukushaya kombani emigqeni ephezulu kungaholela kalula ku-flashover noma ukuwohloka kwama-insulators, okuholela kumafrikhwensi kagesi nama-arcs okushisa aphezulu axhuma ngokushesha izintambo.Ukuze ugweme le ngozi, kuyadingeka ukufaka isivikeli se-overvoltage yomugqa kulayini ongaphezulu.Umsebenzi wawo ukuqondisa umbani wamanje kumvikeli lapho umugqa ongaphezulu ushaywa umbani, futhi unqamule imvamisa yamandla eqhubekayo yamanje ukuze ugweme i-flashover noma ukuwohloka kwe-insulator.Vikela imigqa engaphezulu ekushayweni kombani nasezingozini zokunqanyulwa.
Izici zomkhiqizo
1. Izici zokuvikela ezinhle kakhulu zomkhiqizo, ngomphumela we-synergistic wegebe lochungechunge elakhiwe phakathi kweringi yokukhipha amanzi kanye nentambo evalekile kanye nesici somkhawulo samanje, inganqamula i-freewheeling yamandla futhi igweme ingozi yokunqanyulwa kwentambo evalekile. ngemva kokushaywa kombani;
2. Umkhiqizo Izici zokuvikela ezinhle kakhulu, ngokusebenzisana phakathi kwegebe lochungechunge elakhiwe phakathi kweringi yokukhipha amanzi kanye nentambo evalekile kanye nesici somkhawulo samanje, inganqamula i-freewheeling yamandla futhi igweme ingozi yokunqanyulwa kwentambo evalekile ngemva kombani. isiteleka;
3. Isakhiwo esikhethekile somshini womkhiqizo (Kuhlanganisa uhlaka oluthwala umthwalo kanye nongqimba lwebhafa), ubuchwepheshe bokuhlanganisa isikhombimsebenzisi esiyingqayizivele kanye nenqubo yokubumba yesikhathi esisodwa yejakhethi yenjoloba ye-silicone ukuze kuqinisekiswe ukuthi umkhiqizo ungamelana nokucindezeleka okukhulu kwemishini, ukuvalwa okuthembekile, nokuqhuma. -ubufakazi;
4. Umkhiqizo uphephile futhi uthembekile ekusebenzeni nasekuwunakekeleni.Ngisho noma isivikeli sonakalisiwe ngenxa yezimo ezingavamile, ukuhlanganiswa kokufakwa komugqa ngeke kuthinteke ngenxa yomphumela wokuhlukaniswa wegebe lochungechunge, okuqinisekisa ukusebenza okuphephile kwesistimu yamandla.
Indawo yokusetshenziswa komkhiqizo nokufaka
Sebenzisa imvelo:
1. Ukushisa kwe-ambient: -40 ~ 50 degrees;
2. Ukuphakama: 2000m nangaphansi (isincomo: sebenzisa imikhiqizo ekhethekile ye-plateau ngaphezu kuka-2000m);
3. Imvamisa yamandla: 58-62Hz, (uhlelo lwe-60Hz), 48 -52hz (uhlelo lwe-50Hz);
4. Umoya osendaweni yokufaka akufanele ube namagesi abulalayo amakhemikhali, isitimu, nothuli oluqhumayo;
5. Ukuze kusetshenziswe isikhathi eside ngaphansi kwezimo ezingavamile, umvikeli udinga uku-oda ngokukhethekile, futhi kufanele kucaciswe kusengaphambili:
1) Izinga lokushisa noma ukuphakama kudlula izinga;
2) Kukhona amagesi aswakeme noma abolayo kanye nokungcola endaweni esetshenziswayo (amanzi, insimu kasawoti, isitshalo samakhemikhali, njll.);
3) Imisebe ye-ultraviolet enamandla (ithafa, ukukhanya kwelanga okuqinile nezindawo ezomile, njll.);
4) Izindawo ezingcoliswe kakhulu (indawo yokusebenza yezimayini, indawo yokusebenza yendawo yokwakha, njll.).
Ukufakwa komkhiqizo: faka
ngokuhambisana ne-insulator (PS-15);qala ukhulule ibhawodi engxenyeni engaphezulu yesici esikhawulelayo samanje, cindezela isipikili sokumisa kupuleti lokucindezela eringini yokukhipha amanzi yensimbi engagqwali ungene embotsheni yokuma engaphezulu kwesici esikhawulayo samanje, isikulufu kubhawodi bese uyiqinisa .Bese ubophela isici sokuvimbela ngokuqinile ekuhlanganiseni.Lapho ufaka esigxotsheni, khulula inati empandeni ye-insulator (PS-15), faka imbobo eyindilinga yesixhumi somvikeli kubhawodi empandeni ye-insulator, ukuze indandatho yokudonsa amanzi ibekwe ngokulinganayo nxazonke. i-insulator (PS-15), ukuze ibanga eliphakathi kwabo (Uma igebe phakathi kwendandatho yensimbi engenasici kanye ne-insulator ingalingani, ungalungisa i-angle yendandatho yokukhipha, isikhundla sesixhumi, njll.), futhi ekugcineni uqinise inathi empandeni yesivikelo kanye nebhawodi ekugcineni okungaphansi kwesici esikhawulayo samanje.
Intambo evalekile engaphezulu kufanele ibekwe endaweni eyi-groove phezulu kwe-insulator yenduku (PS-15) (hhayi emgodini oseceleni);igebe phakathi kwendandatho yokukhipha amanzi yensimbi engagqwali kanye nocingo oluvalekile (umgogodla) kufanele ilawulwe ngaphakathi kobubanzi obungu-60-100mm Ngaphakathi, igebe phakathi kweringi yokuphambukisa kanye nesivikeli mandla kufanele lifane futhi lilawulwe ngaphakathi kuka-25±5mm;emigqeni evalekile engaphezulu engaphezulu engahlubuki isendlalelo sokuhlukanisa, ama-arcs endingilizi yezigaba ezintathu kufanele abheke ohlangothini olufanayo futhi kufanele abekwe ngaphandle ukuze kugwenywe izikhala phakathi kwamaringi okuphambukisa.Uma isikhawu sisincane kakhulu, sizoba nomthelela ekuhlanganisweni kokufakwa kwemigqa ephezulu.
Itheminali ephansi ithatha intambo ekhethekile yokubeka phansi, futhi ukumelana nomhlabathi kufanele kulawulwe ngaphansi kuka-30Ω, njengokusebenzisa izinsimbi zensimbi, imicu yensimbi noma insimbi eyisicaba enengxenye engu-50mm2;ezindaweni ezinamagquma nezinye izintaba, ukumelana nesisekelo kukhulu, futhi igridi ekhethekile yokubeka phansi idinga ukwakhiwa.
Kunconywa ukufaka isethi eyodwa phezulu kwesigxobo ngasinye sesisekelo ezindaweni lapho ukulimala kombani kwenzeka njalo;kwezinye izindawo, isethi eyodwa ingafakwa zonke izigxobo ezimbili eziyisisekelo.
