Magnetic controlled reactors

Chii chinonzi MCR?

Magnetic controlled reactors (MCR) imhando yeshunt reactor ine inogadzirika simba, iyo inonyanya kushandiswa kune reactive simba muripo wesimba system.

MCR ine magineti vharafu yekudzora kupenya kweiyo reactor core, iyo inozadza iyo yese iron musimboti uye inovandudza mashandiro zvakanyanya nekushandura chimiro chechoto chemagneti pahwaro hwechinyakare magineti saturation uye reactor. kuitira kutsvedzerera iyo inoshanda inductance ye electrodeless regulator. Schematic diagram ndeiyi inotevera:

MCR inoshanda sei

MCR yakavakirwa pamusimboti weDC magineti, uchishandisa iyo yakawedzera DC yekuwedzeredza magineti reactor musimboti, nekugadzirisa iyo magineti saturation dhigirii repakati peMCR, kushandura permeability yepakati, kuti iwane inoenderera inogadziriswa reactance kukosha. Iyo shunt magineti yedunhu inoumbwa neiyo musimboti munzvimbo isina unsaturated uye musimboti munzvimbo yakazadzwa yakarongedzwa zvakachinjika papakati peiyo reactor; iyo excitation magnetization yepakati nekuwedzera DC excitation ikozvino inodzorwa nekugadzirisa iyo thyristor inokonzera conduction angle; iyo magnetization degree uye saturation dunhu repakati munharaunda isina unsaturated uye nzvimbo yekuzara inoshandurwa nekugadzirisa iyo nzvimbo kana iyo magineti inopikisa yepakati munharaunda isina unsaturated uye saturation dunhu mushunt magineti wedunhu Iyo magineti saturation degree ye musimboti unogona kuona kuenderera uye nekukurumidza kugadzirisa kwekuita kukosha kubva ku1% kusvika ku100%. Yakasanganiswa ne capacitor, inogona kupa yakanaka uye yakaipa inoramba ichigadziriswa reactive simba, saka inogona kudzora system voltage uye reactive simba zvakanyanya uye nekukurumidza. Nekuti hapana kana kushoma kunokanganisa uye inrush inokonzerwa necapacitor switching, kuvimbika uye hupenyu hwebasa hwechishandiso hunogona kuvandudzwa zvakanyanya. Inogona kubhadhara zvikamu zvitatu zvakasiyana, kunyanya panyaya yekusaenzana kwemasimba matatu-chikamu.

Chii basa reMCR

1. Kuwedzera simba uye kuderedza kurasikirwa kwemutsara kunokonzerwa nekugadzirisa simba , kunatsiridza simba rekushandisa kwevashandisi.simba rinogona kusvika kune zvinodiwa zve 0.90-0.99.

2. Kudzvanya uye kusefa maharmonics, kuderedza kushanduka kwemagetsi, flicker, kukanganisa uye kudzikamisa voltage, kunatsiridza hupenyu hwebasa rematransformer, mitsara yekufambisa uye zvimwe midziyo yemagetsi.

3.As reactive power compensation, MCR inogona kugadzirisa kubuda reactive simba zvakanaka, iyo ine mabasa akawanda kupfuura general reactive power compensation equipment.

4. Deredza kukanganisa kwemagetsi emagetsi emunharaunda zvakadai seasynchronous motor start, magetsi arc furnace operation uye kuvandudza kuchengetedzwa kwehurongwa, kunyanya kune isina simba ikozvino network.

1.no chiito chinhu mukati, icho chisingazokanganisa sisitimu;

2.Stepless regulation inogona kuona inoenderera muripo we reactive simba;

3.Kushanda kwakachengeteka, kuchengetedza pasina uye kusina kutarisirwa;

4.Kurasikirwa kwakaderera (kuzvirasikirwa

5.Low rinoshanda simba kurasikirwa;

6.Small harmonic (pasi pe50% yezvigadzirwa zvakafanana);

7.Kuvimbika kwehutano, hupenyu hurefu hwechigadzirwa (kupfuura makore 25);

8.Convenient kuiswa uye nzvimbo duku yepasi;

9.Strong overload capacity, inogona kuremedza 150% munguva pfupi;

10.No electromagnetic kupindira uye kusvibiswa kwezvakatipoteredza.

Ndeipi nzvimbo inoshandisa MCR

Chitima chemagetsi

Kuremerwa kwemagetsi enjanji yekukwevera substation ndeyenguva pfupi. Kana iyo locomotive yemagetsi ichipfuura, mutoro unongoerekana waonekwa. Mushure mokunge chitima chapfuura, mutoro unonyangarika. Kushandisa yechinyakare switching capacitor kuchaita kuti traction substation ichinje mazana enguva zuva rega rega. Chiito, icho chinopfupisa zvakanyanya hupenyu hwebasa remidziyo yemagetsi, uye asymmetry yechitima chemagetsi chinoita kuti chikamu chayo chekutevedzana chive chakakomba.

Marasha uye Kemikari

Kune huwandu hukuru hwezvinopindirana zvinorema zvinorema senge hoist mumabhizinesi emarasha, ayo asingangove nekuchinja kukuru kwesimba rekuita asiwo kusvibiswa kwakakomba kweharmonic, izvo zvinokonzeresa kukuvadzwa kwemidziyo yemagetsi uye kukanganisa hupenyu hwesevhisi yemidziyo yemagetsi.

Metallurgy

Kuremerwa kwechigayo uye yemagetsi arc furnace mune metallurgical system imhando yemutoro wakakosha. Inogona kuchinja mutoro kubva pamutengo muduku kusvika kune yakakosha zvikuru munguva pfupi (pasi pe1s), uye kuwanda kwekuchinja kunokurumidza zvikuru. Nekuda kweizvozvo, zviridzwa zvekuratidzira mumabhizinesi aya zvinogara zvichitenderera nekumhanya kukuru.

Mhepo purazi

MCR-yakavakirwa SVC zvishandiso zvinoshandiswa kuenderera, kusingabatane, uye kusimba kugadzirisa kwesimba rinoita mumhepo purazi substations, kuvandudza simba reiyo system, nekukurumidza kugadzirisa reactive simba kubuda, uye kusimudzira voltage kudzoreredza.

Power substation

Matambudziko ekushandiswa kwakaderera capacitor uye anonetsa switching manejimendi akapararira. Huwandu hukuru hwemidziyo yeVQC yakaiswa nyore nyore kukonzeresa matambudziko akadai sekugara achichinja-chinja mashandiro emabhangi e-capacitor uye kazhinji pa-load-voltage-regulating switch, izvo zvinoderedza hupenyu hwemidziyo uye kuwedzera njodzi dzekuchengetedza.

Vashandisi vakakosha veindasitiri

Mabhizinesi emachira uye vanogadzira machubhu emifananidzo vane zvakakwirira zvinodikanwa zvemhando yezvigadzirwa zvavanogadzira uye nevoltage yemhando yemagetsi. Kamwe kamwe magetsi anodonha kana kudonha kwechinguvana anokonzeresa huwandu hukuru hwemarara muzvigadzirwa zvavo. Kushandisa MCR-mhando static reactive simba muripo wemidziyo inogona Kuvandudza kunaka kwayo kwemagetsi munguva pfupi.
