IKhabhinethi Yokusabalalisa Amandla Aphansi we-GGD AC
Ububanzi Besicelo
Ikhabethe le-GGD AC low-voltage power distribution ilungele abasebenzisi bakagesi njengezitshalo zikagesi, iziteshi ezingaphansi, amabhizinisi ezimboni nabanye abasebenzisi bamandla njenge-AC 50HZ, i-voltage esebenzayo elinganiselwe engu-380V, ekalwe manje njengesistimu yokusabalalisa amandla angu-3150A njengamandla, izibani kanye nezisetshenziswa zokuguqula amandla. , Ukusabalalisa nokulawula.Umkhiqizo unamandla okuphuka okuphezulu, ukalwe ukumelana nesikhathi esifushane kuze kufike ku-50KAa, uhlelo lwesekethe oluguquguqukayo, inhlanganisela elula, ukusebenziseka okuqinile, kanye nesakhiwo senoveli.Lo mkhiqizo ungomunye wemikhiqizo emele ye-switchgear yephaneli ehlanganisiwe futhi engashintshi ezweni lami.
Lo mkhiqizo uhambisana ne-IEC439 "Low-Voltage Switchgear and Control Equipment", GB7251.12-2013 "Low-Voltage Switchgear and Control Equipment Ingxenye 2: Qedela Ukushintsha Amandla Nezisetshenziswa Zokulawula" namanye amazinga.

Izimo Zemvelo
1. Izinga lokushisa lomoya elizungezile alikho ngaphezu kuka +40℃futhi hhayi ngaphansi kuka -5℃.Izinga lokushisa elijwayelekile phakathi kwamahora angama-24 akufanele libe ngaphezu kuka +35℃.
2. Ukufakwa nokusetshenziswa kwangaphakathi endlini, ukuphakama kwendawo okusetshenziswa kuyo akumele kudlule i-2000m.
3. Umswakama ohlobene womoya ozungezile aweqi ama-50% lapho izinga lokushisa eliphakeme lingu-+40℃, futhi umswakama ophakeme wesihlobo uvunyelwe ezingeni lokushisa eliphansi: (isibonelo, 90% ku +20℃), kufanele kucatshangelwe ukuthi izinga lokushisa lingashintsha Umthelela wengozi wokujiya.
4. Uma okokusebenza kufakiwe, ukuthambekela okuvela endizeni eqondile akufanele kudlule ku-5°.
5. Izinto ezisetshenziswayo kufanele zifakwe ezindaweni lapho kungekho khona ukundindizela nomthelela omkhulu, nasezindaweni lapho izingxenye zikagesi zingagqwalile.
6. Uma umsebenzisi enezidingo ezikhethekile, zingaxazululwa ngokubonisana nomkhiqizi.
Imodeli Nencazelo Yayo
Amapharamitha Abalulekile Wezobuchwepheshe
1. Amapharamitha kagesi ayisisekelo akhonjisiwe kuThebula 1

2. Isikimu sesifunda esisizayo
Idizayini yesekethe eyisizayo ihlukaniswe yaba izingxenye ezimbili: uhlelo lokuphakelwa kwamandla kanye nohlelo lwesikhungo samandla.
3. Ibhasi elikhulu
Uma isilinganiso samanje singu-1500A nangaphansi, kusetshenziswa ibhasi elilodwa lethusi.Uma isilinganiso samanje sisikhulu kuno-1500A, kusetshenziswa ibhasi elethusi eliphindwe kabili.Izindawo ezigqagqene zamabhasi zonke ziphathwa nge-tin line.
4. Ukukhethwa kwezingxenye zikagesi
a.Ikhabhinethi ye-GGD yamukela ikakhulukazi izingxenye zikagesi ezithuthuke kakhulu ezingakhiqizwa ngobuningi eShayina.Njenge-DW17, DZ20, DW15, njll.
b.I-1ID13BX kanye ne-HS13BX yokushintsha imimese esebenza nge-rotary ayizingxenye ezikhethekile eziklanywe i-NLS ukuze zihlangabezane nezidingo zesakhiwo esiyingqayizivele sekhabhinethi ye-GGD.Ishintsha indlela yokusebenza yomshini futhi igcine izinzuzo zemikhiqizo emidala.Iwuhlobo olusha olusebenzayo lwengxenye kagesi.
c.Isibonelo, lapho umnyango wokuklama ukhetha izingxenye zikagesi ezintsha ezisebenza kangcono kanye nobuchwepheshe obuthuthuke kakhulu ngokwezidingo zabasebenzisi, ngenxa yokuthi ikhabhinethi ye-GGD inokuguquguquka okuhle kokufaka, ngokuvamile ngeke ibangele ubunzima bokukhiqiza nokufaka ngenxa yezingxenye zikagesi ezibuyekeziwe.
d.Ukuze kuthuthukiswe ukuzinza kwesekethe, ukusekelwa kwamabhasi kwekhabhinethi ye-GGD kusebenzisa uhlobo oluzinikele lwe-ZMJ isigxivizo sebhasi esihlanganisiwe kanye nokusekelwa kwe-insulating.I-busbar clamp yenziwe ngezinto ezihlanganisiwe ze-PPO ezinamandla aphezulu, ezinganqamuki ilangabi, ezinamandla okufaka ugesi aphezulu, ukusebenza kahle kokuzicisha, kanye nesakhiwo esiyingqayizivele.Ingahlanganiswa kalula ibe ibha yebhasi eyodwa noma i-double busbar clamp ngokulungisa ibhulokhi yokwakha.Ukwesekwa kwe-insulating kuyisakhiwo esibunjiwe sohlobo lwemikhono esinezindleko eziphansi namandla aphezulu, esixazulula iziphambeko zebanga elinganele le-creepage lemikhiqizo emidala.
Oda Iziyalezo
Lapho u-oda, umsebenzisi kufanele anikeze idatha elandelayo:
1. Imodeli egcwele yomkhiqizo (kuhlanganise nenombolo yesikimu sesifunda esiyinhloko kanye nenombolo yesikimu sesifunda esisizayo).
2. Umdwebo oyinhloko wokulandelana kwesistimu yesifunda.
3. Umdwebo wohlelo lukagesi lwesekethe elisizayo.
4. Uhlu lwezingxenye kukhabhinethi.
5. Ezinye izidingo ezikhethekile ezingahambisani nezimo ezijwayelekile zokusetshenziswa komkhiqizo.
