Uhlolojikelele Lomkhiqizo
I-GRM6-40.5 Series iwuhlobo olusha lwe-SF6 gas-insulated compact switchgears. Izinqamuli zesekethe, izinqamuli, nezinye izingxenye zivalwe ezitsheni zensimbi ezinogqinsi ongu-3mm ezigcwele igesi ye-SF6 enengcindezi ephansi. Ngakho, okokusebenza kuhlangene, kuthembekile, futhi kuphephile; mahhala emithelela yemvelo, ukunakekelwa kwamahhala kanye nempilo ende yesevisi, njll.
Ama-switchgear e-GRM6-40.5 Series afanele ukulawula, ukuvikelwa kanye nokuqapha kwe-40.5 kV, isigaba sesithathu, isistimu kagesi ye-busbar eyodwa, esetshenziswa kabanzi ezinkampanini ezikhiqizayo, izimayini, njll.
Izilinganiso Ezisebenzayo
I-IEC 62271-1: I-switchgear ene-voltage ephezulu kanye negiya lokulawula-Ingxenye 1: Ukucaciswa okujwayelekile
I-IEC 62271-100: I-switchgear ene-voltage ephezulu kanye negiya yokulawula-Ingxenye ye-100: Iziphuli-mthetho zamanje ezishintshanayo
I-IEC 62271-102 High-voltage switchgear kanye negiya lokulawula-Ingxenye 102: Izixhumi ezishintshayo zamanje namaswishi omhlaba
I-IEC 62271-103 High-voltage switchgear kanye ne-controlgear-Ingxenye 103: Ukushintsha ama-voltage akalwe ngenhla kwe-1 kV futhi akhuphuke afinyelele futhi ahlanganise nama-52 kV
I-IEC 62271-105 High-voltage switchgear kanye negiya lokulawula-Ingxenye 105: Inhlanganisela yamanje yokushintsha-fuse
I-IEC 62271-200: I-switchgear ene-voltage ephezulu kanye negiya yokulawula-Ingxenye 200: I-AC metal-evalelwe i-switchgear kanye negiya lokulawula lamandla kagesi akalwe ngaphezu kwe-1kV futhi afinyelela futhi ahlanganise nama-52 kV
I-IEC 60044-2: Iziguquli zezinsimbi-Ingxenye 2: Ama-voltage angenayo
I-IEC 60044-1: Iziguquli zezinsimbi-Ingxenye 1: Iziguquli zamanje
Sebenzisa Izimo
Ukuphakama: ≤4000m★
Izinga lokushisa lomoya elizungezile: -25℃~+40℃;
Umswakama womoya ohlobene: isilinganiso sansuku zonke ≤95%, isilinganiso sanyanga zonke ≤90%;
Ukuqina kokuzamazama komhlaba ≤8 isigaba;
Izindawo ezingenawo umlilo, ukuqhuma, ukungcola okubi kakhulu, ukugqwala kwamakhemikhali nokudlidliza okukhulu.
Qaphela★: Umkhiqizi kufanele kukhulunywe naye kusenesikhathi uma ukuphakama kwesayithi kungaphezu kuka-1000 m ukuze kulungiswe umfutho wokwehla kwamandla emali.
