Ndezvipi zvinodiwa kuti tambo dzisakuvadzwe zvakanyanya?
Munzvimbo dzine njodzi dzemaindasitiri uko gasi rinobvira, utsi neguruva rinobvira zvinopa njodzi dzekuputika nguva dzose, kusungirirwa kwetambo dzakachengeteka (IS) kunomiririra kudzora kwakagadzirwa kwakagadzirwa kwezvishandiso zvine simba shoma, kutaurirana uye kudzora maseketi. Kusiyana netambo dzemazuva ese, tambo dzakachengeteka dzakagadzirirwa kudzikamisa kuburitswa kwesimba remagetsi mumamiriro ese ari maviri ekushanda uye ekutadza, zvichibvisa zvinhu zvinogona kukonzera kupisa.
Mainjiniya's Core Insight: IS Kukundikana kweCable Kunowanzo dzivirirwa
Kubva mumakore angu eruzivo seinjiniya wemagetsi netambo ndichishanda nemapurojekiti emafuta, makemikari uye emigodhi, ndinotenda zvakasimba kuti kukundikana kwetambo dzeIS hakuwanzokonzereswa nekusakwana kwezvinhu zvakagadzirwa. Pane kudaro, kazhinji kunokonzerwa nekusarudzwa kwedhizaini kusingatevedzeri mitemo, miganhu yemagetsi isina kuteererwa kana kuiswa zvisina kunaka panzvimbo.
Kutevedzera zvakasimba zvinodiwa zvehunyanzvi, zvekuvaka, zvekushandisa uye zvekuisa pasi rose kwakakosha kuchengetedza kuchengetedzeka kwemukati memafuta negesi, makemikari, migodhi uye mashandisirwo ekunze. Chinyorwa chino chinoongorora zvinodiwa zvinofanirwa kutevedzera dhizaini yetambo dzakachengeteka uye hunyanzvi hwadzo, pamwe chete nenyaya dzemapurojekiti chaiwo uye ruzivo rweinjiniya.
Chinodiwa Chekutanga: Kutevedzera Mutemo Wepasi Rose
Kubva pamaonero einjiniya, chinodiwa chikuru chetambo chero ipi zvayo yakachengeteka ndeyekutevedzera mitemo nehunyanzvi zvinozivikanwa pasi rose. Mitemo iyi inogadza zvinodiwa zvakafanana zvekusimbisa dhizaini, kuyedza mashandiro uye kutevedzera mitemo, zvichiita kuti tambo ishande zvakachengeteka munzvimbo dzine njodzi.
Chiyero chepasi rose chehunyanzvi hwemasisitimu akachengeteka, kusanganisira tambo dzinobatanidza, ndeche IEC 60079‑25Inotsanangura zvakadzama zvinodiwa zve capacitance ye wire, inductance, kusarudzwa kwezvinhu uye dhizaini ye structure.
Pakutevedzera mitemo yedunhu: Kuendeswa kweEurope kunoda kutevedzera mitemo ATEX 2014/34/EU murairo (wekupatsanurwa kwenzvimbo dzinoputika); mafomu ekuNorth America anofanira kusangana UL 60079‑11 uye NFPA 70 NEC 504; IECEx Chitupa chinogamuchirwa pasi rose kumapurojekiti anoyambuka miganhu.

Chinodiwa Chehunyanzvi Chekutanga: Kuganhurirwa Kwesimba
Kuganhurirwa kwesimba ndiyo musimboti mukuru wehunyanzvi unotsigira kugadzirwa kwetambo dzakachengeteka. Simba remagetsi rakachengetwa mukati metambo harifanirwe kukwana kuti ribatidze mhepo ine njodzi yakapoteredza—kunyangwe kana paine damburo pfupi kana kuti kutadza kushanda kwechikamu.
Kuti izvi zviitike, mainjiniya anofanirwa kudzora zvakanyanya maparamita maviri akakosha emagetsi: capacitance uye inductance pakureba kweyunitiKune nzvimbo dzine njodzi dzeboka reIIC (semuenzaniso, hydrogen, acetylene), miganhu yekugadzirwa kwayo inowanzo kugona ≤ 200 pF/m uye inductance ≤ 1 μH/m. Aya manhamba anobva pakuverenga simba remasekete kuitira kuti simba guru rinoburitswa panguva yekukanganisa risapfuure simba rekupisa rinopfuta (MIE) rechinhu chinobatidza moto.
Saizi yemuchina wekufambisa magetsi yakaganhurirwawo, nenzvimbo dzakajairwa dzepakati pemagetsi dzinotangira pa0.5 mm² kusvika 2.5 mm² dzichishandisa mhangura yakachekwa mugaba. Kurongeka uku kunoenzanisa kufambiswa kwemagetsi nekuchinjika kwemuchina uye kuganhurirwa kwesimba, nepo simbi ichiputira inodzivirira ngura munzvimbo dzakaoma dzemaindasitiri.

Zvinodiwa pakuvaka: Zvinhu & Dhizaini
Kupfuura zvinodiwa nemagetsi nesimba, kufunga nezvekugadzira zvivakwa kwakakosha kuchengetedza kuchengetedzeka kwemukati menguva yebasa retambo. Zvinhu zvinodzivirira kupisa nekuisa mukamuri zvinofanirwa kusarudzwa nekuda kwekusagona kwazvinoita makemikari, kunonoka kwemurazvo uye kusimba kwemuchina—makemikari epolyurethane (PUR) uye low-smoke zero-halogen (LSZH) anonyanya kufarirwa mumaindasitiri akawanda.
Mainjiniya'Yambiro: Don't Zvisina Kutarisirwa Zvakanyanya Musheya Wezvinhu
Mukuona kwangu, vazhinji vanoshandisa tambo dzePVC vanorerutsa mashandiro etambo dzemugodhi. Tambo dzePVC dzinokurumidza kutsemuka mumiti ine makemikari akawanda, zvichipwanya zvinodzivirira kupisa uye zvichikonzera njodzi dzisingaonekwe dzekuchengetedza.

Kudzivirira & Kupatsanurana Kwedunhu: Dzivisa EMI uye Kusvibiswa Kwemuchinjiko
Kudzivirira uye kupatsanura matunhu zvimwe zvinodiwa nemainjiniya kudzivirira kupindirana kwemagetsi (EMI) uye kusvibiswa pakati pematunhu. Matambo akawanda akachengeteka anowanzo sanganisira kuvharira kaviri (aluminium-polyester foil + high-density copper braid) uye waya yekubvisa mvura kuti ivhurwe.
Kubva pane zvakaitika kwandiri panzvimbo iyi, kusashanda zvakanaka kwekudzivirira uye kutyoka kwekubatanidza waya dzemudhiraivha ndezvimwe zvezvikonzero zvitatu zvikuru zvinokonzera kusagadzikana kwemasaini eIS muzviteshi zvemafuta. Zvakakosha kuti, maseketi eIS anofanirwa kuparadzaniswa netambo dzemagetsi dzisina njodzi mukati, sezvakatsanangurwa muIEC 60079-25, kudzivirira kutamiswa kwesimba kunogona kukanganisa kuchengetedzeka kwemukati.
Kushanda Kwemakanika & Kupisa: Kugara Kwenzvimbo Dzinoda Mari Yakawanda
Zvinodiwa pakushanda kwemakanika nekupisa zvakagadzirwa kuti zvive nechokwadi chekuti tambo dzakavimbika mumamiriro ekushanda akaomarara. Tambo dzakachengeteka mukati dzinofanira kugara dzakakombama, dzakamonyoroka uye dzakakweshwa—dzinowanzoitwa mumarobhoti nemidziyo inofambiswa.
