Tiudzei pamusoro RCD: chii uye sei akunoita

Munguva ino yakakwirira michina vanhu vari takapoteredzwa kuwanda namano uye zvinoshandiswa, kushanda nokubatsira magetsi. Zvino mukuru nhamba, zvikuru mukana yemagetsi kuvhunduka. Kuti izvi zvisaitike, yakanga yakagadzirwa ne RCD. Chii uye nei uchifanira, isu hunonyatsodonongodza munyaya ino.

sarudzo

Mudziyo (RCD) rakagadzirirwa differential kudzivirira munhu wemagetsi kuvhunduka kana kugunzva zvemagetsi kwedzimba (mhuri midziyo yemagetsi), rakanga kwakapa apo kuputira mhosva.

Kana RCD kunouya

Tinoenda nyaya RCD. Chii uye kuti inoshanda sei? Pashure munhu anobata pasi voltage Appliance kwedzimba, magetsi anotanga kuyerera. Kana zvasvika kukosha 30 Ma, ari RCD igumburwe kunoitika. Somugumisiro, kubva voltage iri kwaita akochonorwa kubva hunenge michina. munhu uyu haanzwi chinhu chinorwadza nezvekufadza kuitika dzakakwirira zvikuru dzenzvimbo (50 Ma). Zvinouraya kuvanhu ari kuitika 100 Ma.

Chii inoitwa RCD

Residual ano redunhu mudariki rinosanganisira transformer kuitika, mumwe actuator (ataure maitiro uye pakumedura levers), vaizviita bvunzo hushande. Yakagozha mano ane mu nechivako dzavo uye gadziriro yacho remagetsi Ivan Kuchin kukosha cutoff ano (kudzivirira pfupi-redunhu dzenzvimbo uye zadzisa).

The kushanda nheyo RCD

Chii? Sei mudziyo iri kusashanda? Zvino isu taurira pamusoro zvose izvi zvikuru zvose. Kushanda RCD akateya transformer musimboti kushanda kuitika (DC). Danho uye kushanda conductors neseri razero transformer ano. Panguva dzekudya uchishandisa midziyo (pamwe sanganisika kuputira) kukosha dzenzvimbo inoyerera kuburikidza navo vari vakaenzana nokukura asi pakatarisana nenhungamiro. Somugumisiro, havana kunyengedza mumwe rinobva nekubudisa iri ichitenderera pamusoro CT, zviri zvakakura nokukura asi pakatarisana mune mirayiridzo kuti chose kukanzura mumwe (pamusoro CT yechipiri ichitenderera kumigumo hapana voltage). Kana kuputira mhosva midziyo chikamu Pasika kondakita pari usabuda kuti zvakohwewa kubudikidza grounding kondakita (kana dzimba iri makateyiwa) kana munhu anobata kuti mudziyo uyu. Somugumisiro, huwandu kuitika inoyerera muna kwazvakarerekera kondakita, kunova duku pane Pasika kufamba. Izvi zvinotungamirira pakuti rinobva fluxes ari transformer ichitenderera akasiyana mune zvikuru. Somugumisiro, migumo CT voltage rinooneka. Pashure ataure kwakabatana kwavari, kutira anotanga kuyerera. Paaizosvika kumahombekombe kusvika 30 Ma, ataure, actuating levers nokuputsa hurongwa. The midziyo iri adzima.

The kwebasa rinofanira RCD

Zviri chete pashure kuziviswa uye troubleshooting pamusoro magetsi, izvo zvakazoita kuti triggering ari mudziyo nokutsikirira pasi cocking levers.

mhedziso

Munyaya ino, isu akatanga imi mune nezvedzinza pamwe RCD: chii, sei akunoita uye chii inoshandiswa. Tinovimba ruzivo urwu unobatsira iwe.
