Saizi diki, yakareruka, yakachengeteka uye yakavimbika;
Kukwanisa kwakasimba kwekudzivirira kukanganiswa kwemagineti uye kudzivirira kuputika;
MaRelays anogona kugadziriswa zvichienderana nezvinodiwa nevatengi, zvakaita senzvimbo yekuisa, nezvimwewo;

Taura nesu

ruzivo rwechigadzirwa

Hunhu hwechigadzirwa

Chigadzirwa ichi chinoenderana nezvinodiwa neRoHS;

Chikamu chekubata chigadzirwa chakavharwa kuti chisangane nezvinodiwa neIP67;

Saizi diki, yakareruka, yakachengeteka uye yakavimbika;

Kukwanisa kwakasimba kwekudzivirira kukanganiswa kwemagineti uye kudzivirira kuputika;

MaRelays anogona kugadziriswa zvichienderana nezvinodiwa nevatengi, zvakaita senzvimbo yekuisa, nezvimwewo;

Matinji anovharwa mukamuri receramic uye anozadzwa negasi rine simba rekutonhodza rakawanda;

Kuputika kwemagetsi eDC relay permanent arc, kukanganiswa kwemagetsi eDC ane voltage yakakwira, pane zvinodiwa zvepolarity pamucheto wekubatana, uye hapana zvinodiwa zvepolarity pamucheto wekubatanidza coil.

Tsanangudzo yeCoil

Voltage yezita (VDC)	Dhonza-mukati Voltage (VDC)	Kuburitsa Voltage (VDC)	Simba Rakayerwa (W)
12	≤8.4	≥1	5.5
24	≤16.8	≥2	5.5

1) Dhirowa voltage, voltage yekuburitsa inogona kuchinja zvichienderana nekupisa kwemhepo nemamiriro ekushandisa, ndapota cherechedzai;

2) Kuyerera kwesimba remagetsi rinoshandiswa necoil kunofanirwa kuchengetwa pasi pe5%.

Zvishandiso zveChigadzirwa

1. Sisitimu yekuchaja mabhatiri;

2. Midziyo yeDC ine simba guru;

3. kuchengetwa kwesimba rinogona kushandiswazve;

4. Midziyo yeindasitiri nezvimwe zviitiko;

5. Sero remafuta & Sisitimu yezuva;

6. Zvivakwa zvine chekuita nesimba idzva;

7. Mota itsva dzinoshandisa simba uye mota dzemagetsi dzehybrid.

DC relay rudzi rweswitchgear inoshandiswa kudzora magetsi mu direct current circuit, iyo inoshandiswa zvakanyanya muminda yakawanda. Mashandisirwo ayo makuru anosanganisira switch nekudzivirira mabhatiri ekuchaja nekuburitsa mabhatiri mumotokari itsva dzemagetsi, uye nzira yekuchengetedza kudzivirira kutadza kwemidziyo, short circuit uye moto. Pamusoro pezvo, DC relay dzinoshandiswawo muindasitiri otomatiki, masisitimu emagetsi uye transit yechitima, zvakaita sekudzora switch yeHVDC transmission lines, mashandiro emidziyo mikuru yemakanika, uye kutanga, kubhureka uye kumhanyisa kwezvitima.

Zvakanakira chigadzirwa

◆ DC relay permanent magnet arc blowing uye high voltage DC disconnection ine mabhenefiti anotevera:

Kuvandudza kugona kwekudzimisa arc

Tekinoroji yekudzima arc inoputira magineti inogara iripo inogadzira simba remagineti rakasimba pedyo nearc, kuitira kuti arc iputirwe kuita chimiro che spiral, zvichiwedzera kureba kwayo uye kuramba kwayo, nokudaro ichikurumidzisa kupararira kwesimba uye kuzadzisa chinangwa chekudzima arc nekukurumidza. Tekinoroji iyi inogona kuvandudza zvakanyanya mashandiro ekudzima arc erelay uye hupenyu hwebasa hwekubatana.

Wedzera kuramba kwekubata kwekubata

Mumagetsi akakwira eDC system, nekuti DC current haina zero crossing, arc inonetsa kudzima, izvo zviri nyore kutungamira mukubviswa kwemagetsi zvakanyanya, zvichideredza hupenyu hwemagetsi uye kuvimbika kwechigadzirwa. Nekukurumidzisa kumhanya kwekupwanya kwekubatana uye kuvandudza simba remagineti rinoputika, tekinoroji yekuputira arc yemagineti anogara kwenguva refu inogona kuderedza zvinobudirira kukuvara kwearc kune iyo inobatana uye kuvandudza kuramba kwekubata kwekubatana.

Gadzirisa zvinoenderana nemamiriro ekunze ane voltage yakakwira

Iyo DC relay ine voltage yakakwira inofanira kudimbura circuit ine voltage yakakwira, uye tekinoroji ye permanent magnet blowing arc inogona kukurumidza kudimbura mutoro weDC une voltage yakakwira, kudzivirira kuitika kwemamiriro asina kujairika akadai sekunamatira kana kuputika kwerelay, uye kuve nechokwadi chekuti kutyaira kwakachengeteka. Iyi tekinoroji inonyanya kukodzera kushandiswa kwemagetsi akakwira akadai semotokari itsva dzesimba uye mapombi ekuchaja.

Kuvimbika kwakawedzerwa

Kubatanidzwa kwetekinoroji yemagetsi inoputika nemagneti inogara iripo pamwe nekugadzirwa kweHVDC relay kunoita kuti shanduko yedunhu ikurumidze uye yakavimbika. Izvi zvakakosha zvikuru pamashandisirwo ezvinhu akaomarara akadai semotokari itsva dzemagetsi, nekuti zviitiko izvi zvinowanzoda kuti relay ikwanise kudzima dunhu iri pamuganhu wemagetsi makuru.

Kugadzira zvinhu zvishoma uye kureruka

Madhiraivha eDC ane simba guru anoshandisa tekinoroji yekuputira arc inogarogara kwenguva refu anogona kuitwa madiki uye akareruka, ukuwo achizadza hydrogen nekukwanisa kutonhora kwearc yakawanda kuburikidza netekinoroji yekuvharira kuti awedzere kuvandudza mashandiro avo ekudzima arc uye kuvimbika.

Tekinoroji yekubvisa arc yemagineti isingaperi uye kuchekwa kwevoltage yakakwira kune zvakanakira zviri pachena muHVDC relay, kunyanya mukuvandudza kugona kwekudzimisa arc, kuwedzera kuramba kubatwa necontact shock, kugadzirisa mamiriro ekunze ane voltage yakakwira uye kuvandudza kuvimbika. Zvakanakira izvi zvinoita kuti tekinoroji yekubvisa arc yemagineti isingaperi ive chikamu chakakosha cheHVDC relay, kunyanya mukushandisa mota itsva dzesimba uye masisitimu esimba rinodzokororwa.
