Differential ano. Differential muchina: unhu, chinangwa

Nokuti zvakareruka kunzwisisa differential ano vanofanira kuonekwa panyama kwacho. Kana pane Kumubata insulated achitungamirira nzira, nei pasina yemagetsi kuvhunduka? Mhinduro yacho iri pachena: voga kunodzivisa ano chokubuda kuburikidza nomuviri womunhu. Asi kana miti kondakita, tatanga kuva insulating substrate uye kubata waya? Kuvhiringidzwa ndiro - hapana zvemagetsi kuvhunduka. The substrate hazvirevi kiya dunhu kuburikidza nomuviri pasi.

Pfungwa differential kuitika

Zvakasikwa kuine muviri muitiro akadai differential ano. Pfungwa iyi ndiyo Vector yakawanda, akaratidza sezvo Verengai dzenzvimbo aripo kutenderera, wakatorwa mupfungwa Zvichakadaro dzomumusha. To akazviratidza razvino differential, muviri muitiro kuitika, inonzi leakage ano. Asi zvinokosha kunge akabvumirana bedzi chivako zvokushandisa, paiva leakage kuitika kuti zvakabatana pasi. Zvikasadaro, kana muviri hauna makateyiwa, ipapo panowanikwa leakage kuitika haakonzeri munhu differential kuitika. Uye residual ano wedunhu mudariki (RCD) zvikasashanda.

Kukurukurirana pakati differential uye leakage pari

Kana kuitika leakage rinowanikwa mudunhu, izvozvo mberi okunze ane conductive zvinhu (housings simbi kuti midziyo yemagetsi, zvikwepa kudziyisa, etc.) Kubva zvikamu pasi voltage (magetsi nematunhu, waya). Munguva idzi pfupi-leakage site havana. Uye saka hapana chokwadi kwemutariri kuita kutyorwa (pachena payo lesion).

Sezvo differential pari apo ayo Express mathematically rinomirira musiyano (vector ukoshi) pakati magetsi panguva panobva goho kuitika uye mushure mutoro, zvinonzwisisika kuti anenge kufanana kuti leakage ano. Asi kana yokupedzisira ariko zvechokwadi mutemo, akadai kuputira, mukuru mwando zvakatipoteredza, kuburikidza raakanga anogona kupfuura, kana zvimwewo, asi differential ano rinowanika kana kubatana pamwe nenyika.

Igumburwe uye vasiri igumburwe differential dzenzvimbo

Under ano igumburwe (kana igumburwe) vanoziva munhu differential aibuda kuitika chinoguma imwe disconnection VDT idonhe chuma.

Kuerera razvino riri bvumidzwa aitenderera mudziyo (RCD) uye actuation yayo rikasaitika anonzi differential vasiri igumburwe iyezvino.

The dzakatakura Dunhu achishandisa kupomba-mhando mudziyo: rectifiers, discrete digitaalinen mano kuti simba kudzora - zvose midziyo ano, kuvapo makuriro dzenzvimbo differential. Asi dzenzvimbo izvi hazvisi dzenzvimbo zvakakanganisika, uye dunhu nemagetsi pane iyi hazvigoni akochonorwa. Naizvozvo RCD igumburwe pachikumbaridzo anosarudzwa akadai kwete vakaitei uchishandisa kukosha necheseri, uye kudzima leakage pari kwazvo kukosha ichi.

RCD kana differential Machine

Kuti adzivirire redunhu pamusoro pasi mhosva dzenzvimbo makuru uwandu, yakatanga chaiyo redunhu kutinhira. Driving mudziyo nguva anoedza kudzorwa redunhu kuti magetsi leakage. Kana Vector Verengai mutsetse dzenzvimbo tsika kuchapfuura razero uye anopinda vasabatwa muganhu, akabva akavhara redunhu. Kwakadaro hurongwa iri uye ari oga-chehupenyu uye zvitatu-danho mitsetse.

Unhu differential haizoshandisi

Various okunatsiridza anodzivirira mano akasiyana mumwe ne:

• patani zvinhu;
• zvinoreva leakage dzemagetsi;
• utetsa Kurongwa;
• nokukurumidza.

Zvichienderana akagadzira zvinhu vari:

• VDT mudziyo (differential chinja), sezvamakaropafadzwa hapana kudzivirira dzakakwirira dzenzvimbo. Ivo vanoita kuti leakage dzenzvimbo, asi kudzivirira zano ravo, nguva tinoda zvinosanganisira fuses.
• RCBOs midziyo apo akapa zvaitika mhando chinja. Ava yezvisikwa Namano hunyambiri basa - kudzivirira remudunhu pfupi uye zadzisa, uyewo leakage kuzvidzora.
• BDT mudziyo pamwe zvichibvira pamotokari muchina panguva kubatana pfungwa. The mudziyo zvichiitirwa iiswe pamwe redunhu mudariki. magadzirirwo ayo ari akashanda nenzira kuti chete kunoita imwe-nguva chokuita kuti muchina.

Zvichienderana Maumbirwe leakage dzenzvimbo yakatanga unodzivirira boka mano dzinotevera okunatsiridza:

• AC - mano zvichishanda rakatumbuka sinusoidal ano. Havadi kupindura differential kupomba dzenzvimbo izvo kuitika panguva apo Somuenzaniso, fluorescent, nezhenje X-ray midziyo, mano kuti processing ruzivo anonongedzera, thyristor converters.
• A - zviridzwa vadzivirirwe kuramba pulsating uye rakatumbuka ano. Havazivi yepamusoro kupomba differential leakage dzenzvimbo. Vanoshanda zvemagetsi nematunhu zvakadai rectifiers, regulators panzvimbo kutendeuka. Kudzivirira nyika leakage pulsed magetsi, izvo ane dzose zvinoriumba voltage.
• B - hurongwa uchishanda shanduka, kugara uye pulsating leakage ano.

Utetsa differential chinja ane marudzi anotevera:

• Low utetsa maitiro kuti chokukuvadza remudunhu kunanga kuonana.
• Systems dzakakwirira-hurongwa wanda. Dzivirirai, kana pane zvave zvakananga kuonana kusvika kondakita.
• Fire-achirwa chiito.

Maererano nguva inodiwa yokuti zano oparesheni:

• Pakarepo chiito.
• High Speed.
• Nokuti vakawanda chinangwa.
• Kunonoka - mhando anyatsosarudza.

kuitika differential kudzivirirwa selector mano anogona chokukuvadza chete chikamu midziyo, uko kukanganisa zvakaitika.

Sei residual ano redunhu mudariki

RCD rinoumbwa panozogadzirika ari muchimiro mhete uye vaviri Coils. windings ava zvakangofanana, zvakaitwa imwe waya muchinjikwa chikamu uye uwandu vachichinjana zvakafanana. Pashure mumwe coils kuitika inoyerera mutoro chiyamuro gwara, uye zvakare kuburikidza mutoro rinodzokera wechipiri ichitenderera. Sezvo mutoro neimwe inopfuura ari yavose sezvavakatarirwa uno, kuti dzenzvimbo vari akapfupikisa panguva kwezvavakaisa panguva goho pamusoro Kirgofu anofanira kuva akaenzana. Somugumisiro, mashoko dzenzvimbo ari windings anosika chete rinobva nekubudisa rinotungamirirwa negwara risiri. Rwako izvi zvaizopedza mumwe uye hurongwa unorambira chete mamiriro. Dai chete paiva leakage kuitika, remagineti achava akasiyana, zvichaita kushanda differential ano ataure, izvo zvichaguma pakuvhurwa magetsi vokukurukura. The yemagetsi mutsetse zvichabviswa zvachose de-kwakapa.

Where zvinoshanda kuchengeteka residual mudziyo ano

Mazuva kuvaka uye magetsi munzvimbo, uyewo yagadziriswa zvikuru kushandiswa namano kuti residual iyezvino. Izvi hunoruramisa nokuwedzera operative kuchengeteka magetsi network, uyewo vasanyanye akuvara. RCDs zvinoshandiswa:

• voruzhinji, zvivako: zvikoro, tsika zvivako, zvipatara, hotels, zvivako mitambo;
• Zvivako uye munhu chokugara mufurati: dzimba, anamapako, hostels, ancillary dura;
• Zvitoro nzvimbo, kunyanya akaita maererano simbi hurongwa;
• Zvivako nokuti administrative zvinangwa;
• maindasitiri mabhizimisi.

Connection mikana Zvirongwa RCD

ano sechokudzivirira Differential kubudisa yakasiyana nenhamba kuongororwa maitikiro. Pane chimwe chinhanho, mbiri-danho uye zvitatu-danho residual ano vematunhu kutinhira.

Kana mutsetse kuroorwa kutotanga uye anofanira chokuita nayo uye RCD kuroorwa redunhu mudariki, zvinoita mutsauko pakati Zvinotaurwa kuisa pakutanga. mano zvose izvi anoiswa pamusoro redunhu panoitwa. Simply yamunenge kupfeka wokutanga otomatiki kutotanga uye residual ano redunhu mudariki pashure. Sezvo mutoro wacho ipapo zvakabatana vokukurukura vose RCD pachinzvimbo danho - iri muchina, panzvimbo razero - iri dziviriro mudziyo.

Kana mukuru mutsetse rakakamurwa wandei mitsetse pamwe mitoro, kuti RCD kuisa pakutanga, uye zvino nokuda mutsetse nerimwe dunhu mudariki. Zvakakosha kuti yavose sezvavakatarirwa ano kuti runogona RCD, yakanga yakareba muchina uchishandisa razvino, zvimwe haana kukwanisa kudzivirira mudziyo pachayo.
