1. Imwe-Core Cable Sheath End Grounding Method, Nei Uchifanira Kuiswa Pamwe Chete Cable Yakaiswa Mukufanana neReturn Line?

Mune simbi sheath magumo epasi tambo tambo, chengetedza kuti induced voltage musheath haipfuure mwero unobvumidzwa.

Inofanirwa kuiswa pamwe netambo yetambo parallel yekuisa conductor, uye migumo miviri yomutyairi wakatsikirirwa, conductor uyu anonzi mutsara wekudzokera.

Kana imwe-chikamu chepasi chikanganiso chikaitika, iyo grounding short-circuits current inogona kuyerera ichidzokera pakati pegadziriro kuburikidza nemutsara wekudzoka.

Seyazvino yekumisa kuburikidza nemutsara wekudzoka unogadzirwa neiyo magineti flux inobvisa chikamu cheiyo magineti flux inogadzirwa netambo conductor grounding current., nokudaro kuderedza iyo induced voltage ye sheath kana pfupi-circuit kukanganisa.

2. Cable Mabasa Anogona Kukamurwa MuMapurojekiti akati wandei?

(1) Site transportation: kusanganisira kurodha nekuburitsa zvinhu zveinjiniya kubva mudura kuenda kunzvimbo yekuvaka, transport, uye isina chinhu backhaul.

(2) Mabasa emunharaunda: kusanganisira kucherwa kwemigwagwa, mugero uye mugero kuvaka, etc.

(3)Kuisa mabasa: kusanganisira kuisa, kugadzira musoro wepakati, achisimudza chivharo, pombi yakavigwa, chikoro, traction musoro kugadzira, etc.

(4) Magumo ese ari maviri epurojekiti: rutsigiro, kuturika zambuko, uye kugadzirwa kwayo kwehwaro uye kuiswa, kugadzirwa kwemusoro wekupedzisira, mafuta ekumanikidza, uye kuisa chiratidzo mudziyo, zita remhando yemagetsi maitiro ekuongorora, etc.

(5) Plugging engineering: kusanganisira kugadzirwa kwemafuta-akazadza tambo yekuisa plugging musoro, kuiswa kwetangi rekupa mafuta, otomatiki drainage uye kusaina mudziyo, etc.

(6) grounding engineering: kusanganisira majoini ekudzivirira, transposition mabhokisi, vadziviriri, grounding box installation, etc.

3. Ndeapi macheki Anofanirwa Kuitwa Kunze kwekugamuchirwa kweCable Lines?

(1) Tsanangudzo dzetambo dzinofanirwa kuenderana nezviga, gadziriro yacho inofanira kuva yakatsvinda, pasina kukuvara, uye zvakakwana, correct, uye mavara akajeka.

(2) Iyo yakagadziriswa bending radius yetambo, chinhambwe chine chekuita uye wiring yesimbi sheath ye-single-core power cable inofanira kusangana nezvinodiwa.

(3) Cable kuguma, musoro wepakati haubvisi mafuta, yakaiswa zvakasimba, mafuta-akazadza tambo yemafuta kumanikidza uye mita calibration kukosha inofanira kusangana nezvinodiwa.

(4) Good grounding.

(5) Iyo cable terminal phase color ndeyechokwadi, uye zvikamu zvesimbi zvebhureketi zvakapendwa zvisina kusimba.

(6) cable mugero uye mugero, zambuko harifaniri kunge risina tsvina, uye ndiro yekuvhara yapera.

4. Ndezvipi Zvinodiwa zveCable Line Positive Sequence Impedance Measurement process?

The the AC kuramba kwetambo conductor uye chikamu chechikamu chematatu akafanana inductances etambo inonzi yakanaka sequence impedance.

Iyo yakanaka sequence impedance yetambo tambo inogona kuyerwa yakanangana netambo tray, uye yakaderera voltage inowanzoshandiswa pakuyera.

Saka, danho-pasi transformer rinodiwa kudzika pasi voltage, the step-down transformer inoshandisa nyeredzi wiring, uye huwandu hwacho hunowanzo 10kVA kana kupfuura.

Kune huwandu hwakawanda hwemitemo yemagetsi, kuyerwa kwemagetsi e AC kunofanirwa kugadzikana kuti ive nechokwadi chekuti kuyerwa kweiyo ikozvino kunosangana nezvinodiwa.

Iyo chaiyo voltage mita yekuverenga kukosha inofanira kunge iri voltage pamagumo etambo, bvunzo ikozvino yakanaka padyo neiyo yakareba inobvumidzwa tambo ikozvino, kuyera uye kuverenga kukosha kwemamita imwe neimwe, vhara yazvino uchiverenga kukosha kwematafura matatu.

5. According To The “Electrical Production Safety Regulations”, Vashandi veMagetsi Vanofanirwa Kuve neMamiriro Ekuti Chii?

Inofanira kuva nemamiriro anotevera.

(1) kuzivikanwa nehutano hwemuviri hwechiremba, hapana zvirwere zvinodzivirira basa.

(2) vane ruzivo rwemagetsi runodiwa, maererano nerudzi rwemabasa avo, uye kushanda kuti ugone mirairo yakakodzera, unyanzvi unyanzvi, uye nzira dzekuchengetedza kuchengetedza, uye akapasa bvunzo.

(3) vane hunyanzvi munzira dzekutanga dzerubatsiro rwe electrocution.

6. Chii Chinofanira Kucherechedzwa Mukuita Kwekutakura Kurodha uye Kuburitsa MaCables?

(1) mukutakura kurodha nekuburitsa, haifanire kuita kuti tambo netambo tireyi zvikuvadzwe, zvinorambidzwa zvachose kusundira tambo yetambo zvakananga kubva kumotokari, iyo tambo senge haifanirwe kunge iri flat transport kana flat storage.

(2) usati watakura kana kukungurutsa tireyi yetambo, inofanirwa kuve nechokwadi chekuti tireyi yetambo yakasimba, cable winding tight, tambo yakazara-mafuta kune tangi yekumanikidza pakati pepombi yemafuta inofanira kugadziriswa, haingakuvadzi, iyo tangi yekumanikidza inofanira kuva yakasimba, chiratidzo chekumanikidza chinofanira kusangana nezvinodiwa.

7. Ndeapi Matanho eCable Fire Kudzivirira?

(1) Kushandiswa kwe tambo dzinodzivirira moto.

(2)Gamuchira tambo yetambo yebhureketi.

(3) Kushandiswa kwezviputi zvinodzivirira moto.

(4) cable tunnel, mezzanine kubuda, etc. isa moto partition wall, moto baffle.

(5) tambo dzepamusoro dzinofanira kudzivirira mapaipi emafuta, uye magonhi asingaputike, zvikasadaro panofanira kuve nekutora pombi dzepanzvimbo kana nzira dzekudzivirira moto.
