Nhau dzeZvigadzirwa

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.

Tambo dzakachengeteka mukati dzinofanira kunge dzakapfava sebhuruu (RAL 5015) zvichienderana neIEC 60079-14 kuti dzionekwe nzvimbo ine njodzi.
Kodhi iyi yemavara inosungirwa inobvumira mainjiniya emagetsi kusiyanisa ipapo ipapo macircuit eIS kubva kune tambo dzemagetsi dzisiri dzeIS, zvichidzivirira kubatana kwesimba rine njodzi netsaona.
Dzidza zvinodiwa uye zvisingawanzoitiki.

Waya yakachengeteka (IS) yakagadzirwa kuti ikwanise kutakura simba remagetsi risingakwanise kukonzera moto mumhepo inoputika.

Kusiyana netambo dzisingaputike dzine kuputika, tambo dzeIS dzinodzivirira kuputika zvachose. Dzidza tsananguro yetambo yeIS, zvinodiwa pakuvaka, kodhi yeruvara rwebhuruu, uye maparamita echinhu zvichienderana neIEC 60079-11.

Waya yakachengeteka haigone kugadzira kana kuchengetedza simba remagetsi rakakwana kuti rikwanise kupfuta munzvimbo dzinoputika. Dzidza tsananguro, kuti zvipingamupinyi zvinoderedza simba zvinoshanda sei, nei simba shoma (C) uye simba shoma (L) zvichikosha, uye nei kodhi yeruvara rwebhuruu ichidikanwa pasi rose pakuisa nzvimbo dzine njodzi.

Waya yeIntrinsically Safe (IS) inodzikisa simba remagetsi kudzivirira kuputika munzvimbo dzine njodzi. Kusiyana nemagadzirirwo asingaputike (Ex-d) ane kuputika, waya dzeIS dzinomisa kubatidza nekudzora voltage/current. Dzidza nezve blue sheaths, zvinodiwa zvekudzivirira, uye parameters dzechinhu zvichienderana neIEC 60079-11.

Tambo dzeIntrinsically Safe (IS) dzinodzora simba remagetsi kudzivirira kubatidza munzvimbo dzinoputika dzemugodhi. Dzine maparamita e capacitance/inductance anodzorwa ane coding yebhuruu-ruvara rwebhuruu zvichienderana neIEC 60079-11, sarudzo dzekudzivirira dzakavharirwa Ex-ia/Ex-ib ratings, uye magadzirirwo etambo dze sensor dzinochinjika kuti dzitevedzere kuchengetedzeka kwemugodhi wepasi pevhu.

Tambo dzakatsetseka (ribbon/FFC) dzinochengetedza nzvimbo, dzinobatanidza maconductor akawanda dzakanakira marobhoti uye otomatiki. Dzine FEP insulation (-90°C kusvika +200°C), sarudzo dzeconductor (CU/TC/SPC/NPC), uye dziviriro yakavharirwa kana isina kuvharwa. Gwaro iri rinofukidza kutumira data nekukurumidza, mabhenefiti ekugadzira akaomesesa, uye zvinodiwa zvekusarudza marobhoti anoda kushandiswa.

Kwete, RS485 neCAT6 hazvina kufanana. Tambo dzeRS485 dzakagadzirirwa kutaurirana kwemaindasitiri kure (1,200m) ne120Ω impedance yemanetwork eModbus RTU. Tambo dzeCAT6 dzakagadzirirwa Ethernet inomhanya zvakanyanya (100m, 100Ω impedance) munzvimbo dzehofisi/LAN. Gwaro iri rinoenzanisa maparamita akakosha anopfuura gumi nemaviri kuti abatsire mainjiniya kutsanangura nemazvo.

Tambo dzeRS485 neEthernet dzinoshanda zvakasiyana mukukurukurirana kwemaindasitiri. Gwaro iri rinoenzanisa zvirevo zvavo, zvinodiwa pakudzivirira, uye mashandisirwo akakodzera kuti zvikubatsire kusarudza zvakanaka.

Tsvaga chikonzero nei Tambo dzeRS485 ndivo vanotungamira mumusika mukuita otomatiki kwemaindasitiri. Dzidza nezve impedance (120Ω), zvinhu zvekudzivirira, uye masarudzo akakodzera eModbus neCANopen systems.
