4. Sephetho sa ho sefa: tumellanong le IEC61000, GB/T14549-93
5. Mocheso oa ho sebetsa: -10 ~ +50 (℃);Mocheso oa polokelo: -40 ~ +65 (℃);Mongobo oa tikoloho: 0 ~ 98(%) ha ho condensation;Boima: <2000M
6. Sebopeho: Sebopeho se tloaelehileng, ho kenya fatše, kapa ho iketsetsa bareki (ho ikhethela)
7. Bokhoni ba ho jara: boima bo feteletseng ba 120% ba boleng bo lekantsoeng bo sebetsa ka tloaelo metsotso e 30
8. Mokhoa oa ho kenya: ho kenya ka thoko, ho kenya ts'ehetso, kapa ho ikhethela ha bareki (ho ikhethela), behella ka thōko sebaka sa 100mm sa ho senya mocheso ho pota-pota sefahla sa harmonic.
9. E sebelisoa bakeng sa ho sefa tšitiso e matla ea indasteri, haholo-holo e loketseng inverter.
1. Tsamaiso e pharaletseng ea filthara ea harmonic ka 'musisi oa phetoho ea maqhubu (VSD) le potoloho e' ngoe ea mekhahlelo e meraro e hlahisoang ke li-harmonics tse ka sehloohong;
2. Fokotsa tahlehelo ea harmonic ea tsamaiso ea ente, kahoo ho boloka matla, katleho> 99%;
3. Etsa bonnete ba hore tekanyo ea hona joale le ea ho sotha ha motlakase qetellong ea ho kenya letsoho ea filthara ea harmonic e finyella litlhoko tsa maemo a 1EEE 51.9;
4. Kakaretso ea tekanyo ea hona joale ea ho sotha tlhokahalo (TDD) qetellong ea ho kenya letsoho ea filthara ea harmonic ha e fetise moeli o boletsoeng ho Lethathamo la 10.3 la 1EEE 51 9 standard;
5. Ka lebaka la matla a tlaase haholo a capacitive reactive, a ka sebelisoa hantle ka lijenereithara tsa diesel esita le ha a laolloa;
6. Low capacitance reactive matla hape ha ho hlokahale ho sebelisa capacitive switjha contactor (e ka boela ekeletsoa ha ho hlokahala);
7. Ka har'a mefuta e tloaelehileng ea mojaro, matla a matla a ntse a le pakeng tsa 0.95 le 0.98 (40 ho 100% mojaro);
8. E ke ke ea lumellana le likarolo tse ling tsa tsamaiso ea matla, e ke ke ea amohela li-harmonics ka lehlakoreng la mohala;
9. E ka thibela lekhalo la commutation voltage waveform, ho bula le ho koala libanka tsa capacitor kapa tse ling tse fetohang ka potlako tse hlahisoang ke overvoltage;
10. Ntlafatsa ntlha ea matla ea tsamaiso eohle ka mor'a ho felisa li-harmonics;
11. Tabeng ea feela frequency conversion governor load, e loketseng phepelo ea motlakase ea phepelo ea maqhubu a mangata ka nako e le 'ngoe;
12. Fokotsa frequency conversion governor (VSD) e hlahisoang ke tšitiso ea radio conduction;
13. Li-filters tsa line reactor tsa litlhaloso tse fapaneng li teng bakeng sa AC drive, DC drive kapa lisebelisoa tse ling tse laolehang tsa ho lokisa.
Filter ea "harmonic" e sa sebetseng e ka sebelisoa haholo ka tsela e latelang:
Sesebelisoa sa ho tjhaja ka potlako sa Dc
Setsi sa moea se futhumatsang le se futhumatsang moea
Sistimi ea ho ntša moea le pompo
Lisebelisoa tsa indasteri le liroboto
Ac le DC motor drives, inverters
Sesebediswa se nang le sekotjana se ka pele sa six-pulse
1. Tšebeletso ea ODM / OEM e fanoa.
2. Tiisetso ea taelo e potlakileng.
3. Nako ea ho fana ka potlako.
4. Nako e loketseng ea ho lefa.
Hajoale, k'hamphani e ntse e holisa ka matla limmaraka tsa mose ho maoatle le sebopeho sa lefats'e.Re ikemiseditse ho ba e nngwe ya dikgwebo tse leshome tse ka hodimodimo tse romelwang kantle ho sehlahiswa sa China sa othomathike sa motlakase, se sebeletsang lefatshe ka dihlahiswa tsa boleng bo hodimo le ho fihlella maemo a tlholo ka bareki ba bangata.
