Izinto ezidingekayo zokuhlolwa kwekhwalithi yamandla
Njengamanje, izinkampani ezihlinzeka ngogesi zinezidingo eziqinile kakhulu ngekhwalithi yamandla.Ukuhlolwa kokusetshenziswa kukagesi kokwandisa ibhizinisi noma ukwakhiwa kwephrojekthi entsha akuseyona nje ukuthi umthamo wesistimu yamandla kanye nokucushwa kwendawo yamandla kungokwesayensi futhi kunengqondo.Umthelela wesistimu yamandla ubeka phambili izidingo zokuhlola ezengeziwe.Ukuze usize amabhizinisi ukuthi aphumelele isicelo samaphrojekthi amasha, i-Power Quality Division ye-Zhejiang Hongyan Electric Co., Ltd. ihlinzeka ngokuhlolwa kwekhwalithi yamandla kanye nezinsizakalo zokuhlaziya amaphrojekthi amasha, okuhlanganisa imigqa yezokuthutha yesitimela emikhulu, Ukuqhuba ukuhlolwa kwekhwalithi yamandla. kanye nokuhlaziya eziteshini zokuthutha umphakathi, amaphrojekthi esithandweni sikagesi esigayweni sikagesi, izisekelo zokukhiqiza amabhizinisi amakhulu, ukuhlelwa kwangaphambili kokusatshalaliswa kwamandla epaki, izakhiwo zezohwebo, njll., ukuze izinkinga zekhwalithi yamandla zilawuleke ngokwesayensi ekuqaleni kwesigaba sokuqala iphrojekthi esikhundleni sokulinda kuze kube ikhwalithi yamandla Ngemva kokuba inkinga igqanyisiwe futhi inomthelela omkhulu, izinyathelo zokulungisa ziyathathwa.
Ukuhlolwa kwekhwalithi yamandla kufaka phakathi ukuhlolwa kwezinkomba zekhwalithi yamandla njengama-harmonics, ukushintshashintsha kwamandla kagesi kanye nokucwayiza, isici samandla, nokungalingani kwezigaba ezintathu ngokulingisa, ukuhlaziya, nokubala umthelela wemithwalo yamandla ohlelweni lwamandla lomsebenzisi kokujwayelekile kwesistimu. amaphuzu okuxhumana., Umbiko wokuhlola ungakhishwa zingakapheli izinsuku eziyi-10 zokusebenza uma okokusebenza kuqediwe.
Ishadi eligelezayo leSikimu Sokuhlola Ikhwalithi Yamandla
Okuqukethwe kokuhlaziya:
Lingisa, hlaziya, futhi ubale umthelela womthwalo wamandla kusistimu yamandla omsebenzisi ezindaweni zokuxhuma ezivamile zesistimu, okuhlanganisa izinkomba zekhwalithi yamandla ezifana nokuvumelana, ukushintshashintsha kwamandla kagesi kanye nokucwayiza, isici samandla, nokungalingani kwezigaba ezintathu.

Izinto okufanele zinikezwe abasebenzisi (izinto ezizonikezwa ukuhlolwa kwekhwalithi yamandla esistimu yamaphrojekthi amasha)
Iqembu eliphathisiwe kufanele linikeze ulwazi olulandelayo futhi linamathisele uphawu olusemthethweni
1. Uhlelo lokusetshenziswa kwamandla, umbiko wocwaningo lokuthi kungenzeka yini, kanye nemidwebo yedizayini (okuhlanganisa umdwebo oyinhloko wesistimu yamandla) eklanywe i-Electric Power Design Institute egunyazwe i-Power Supply Bureau.
2. I-voltage yesistimu yendawo yokungena yomphakathi, umthamo wesistimu ye-short-circuit, umthamo wephrothokholi yesistimu, namandla okuphakelwa kwamandla wesistimu okugunyazwe yisikhungo sokuphakelwa kukagesi.
3. Amapharamitha wobuchwepheshe be-Transformer (umthamo, isilinganiso se-voltage, indlela yokufaka izintambo, i-impedance voltage)
4. Uhlu lwawo wonke amapharamitha womthwalo (ohlelwe ngokwehlukana ngokomthwalo othwalwa yi-transformer ngayinye)
Kubandakanya igama lomthwalo, inani, amandla alinganiselwe, i-voltage;
Ikakhulukazi, izinto ezisetshenziswayo zokulayisha ezingezona umugqa kufanele ziqashelwe ngokukhethekile:
Ngemithwalo engaqondile, njengamandla ahlukahlukene angaphazamiseki (i-UPS yekhompyutha, njll.), izibani zokukhipha igesi (izibani ezonga amandla, izibani ze-fluorescent, izibani zemercury ezinomfutho ophezulu, izibani ze-sodium ezinomfutho ophezulu kanye nezibani zensimbi ze-halide, njll.), impahla yasehhovisi (amakhophi, imishini yefeksi, njll.), izinto zikagesi zasendlini (izikrini zokubonisa, amahhavini ama-microwave, omabonakude, iziqopha-video, amakhompyutha, izibani ezifiphalisayo, izipheko ezilawula izinga lokushisa, ama-air conditioner, njll.), okokusebenza kagesi (imishini yokulungisa i-thyristor , okuhlanganisa izitimela zikagesi, amaseli e-aluminium e-electrolytic, izinto zokushaja, izinto zikagesi ezishintshayo, njll. Imishini yokulungisa kabusha), okokusebenza kokushisela, okokusebenza kokuguqula imvamisa (evame ukusetshenziswa kumafeni, amaphampu amanzi, amakheshi, ama-air conditioner), izigayo eziginqikayo, izithando zikagesi ze-arc, izithando zomlilo ze-calcium carbide, amafrikhwensi amaphakathi, okokusebenza kwe-electroplating, njll. Isitatimende sikasayizi we-harmonic we-harmonic kanye nosayizi wokuhlanekezela wamanje we-harmonic noma umbiko uzonanyathiselwa uphawu olusemthethweni lweyunithi yokukhiqiza.
5. Indlela yokuhlola: (sicela ukhethe okumbalwa noma konke, le nto yinto yokuqala)
