Filter ea Passive Harmonic Bakeng sa Vfd Three Phase 400v

Tlhaloso e Khutšoanyane:

Filter ea passive harmonic e sebelisa molao-motheo oa induction ea electromagnetic le reactor, e khetha filthara e nang le ts'ebetso e phahameng le sesebelisoa sa filthara se nang le linearity e phahameng, 'me e kopanya sistimi ea puseletso ea filthara ho monya likarolo tse kholo tsa sistimi le ho lefella matla a sebetsang. nako yona eo.

Ts'ebetso ea puseletso ea matla a ts'ebetso e matla le ho sefa e kenyelelitsoe ho e le 'ngoe, e ka latelang phetoho ea mojaro ka potlako,' me e na le mesebetsi e meraro e meholo: ho hatella ho fetoha ha hona joale, ho monya harmonic le ho lefella matla a sebetsang.E sebelisetsoa ho fokotsa maqhubu a non-sine wave a hlahisoang ke li-inverters, li-drive tsa servo, UPS, joalo-joalo, ho li-grids tsa matla a indasteri.

Sefahla sa li-harmonic se sebelisoang haholo tsamaisong ea terata ea mekhahlelo e meraro.E sebelisa molao-motheo oa induction ea electromagnetic le reactor, e khetha "filter capacitor" e nang le ts'ebetso e phahameng le sesebelisoa sa filthara se nang le linearity e phahameng, 'me e kopanya sistimi ea puseletso ea filthara ho monya likarolo tsa mantlha tsa sistimi le ho lefa matla a sebetsang ka nako e le ngoe.Ts'ebetso ea puseletso ea matla a ts'ebetso e matla le ho sefa e kenyelelitsoe ho e le 'ngoe, e ka latelang phetoho ea mojaro ka potlako,' me e na le mesebetsi e meraro e meholo: ho hatella ho fetoha ha hona joale, ho monya harmonic le ho lefella matla a sebetsang.E sebelisetsoa ho fokotsa maqhubu a non-sine wave a hlahisoang ke li-inverters, li-drive tsa servo, UPS, joalo-joalo, ho li-grids tsa matla a indasteri.

1. Boemo ba motlakase: mekhahlelo e meraro ea terata e lekantsoeng ka matla a 380-500V, ho kheloha ho amohelehang ± 10%

2. Taolo ea Harmonic: THDi<10%, nomoro ea harmonic 2n-1 = 1 ~ 40

3. Hangata: 50±5 (Hz);Ntho ea matla: bophara ba COS> 0.9

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 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.

Kopo

Filter ea "harmonic" e sebetsang e ka sebelisoa haholo ka tsela e latelang:

Sesebelisoa sa ho tjhaja ka potlako sa Dc

Ac le DC motor drives, inverters

Sesebediswa se nang le sekotjana se ka pele sa six-pulse

Tšebeletso ea bareki

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.
