Malinga ndi zofunikira zosiyanasiyana zotsimikizira kuphulika, zida zamagetsi zosaphulika za migodi zimagawika m'mitundu ya migodi, yowonjezereka ya chitetezo cha migodi, mtundu wa chitetezo cha migodi, mtundu wabwino wa migodi, mtundu wodzaza mchenga wamigodi. , mtundu woponyedwa m'malo opangira migodi ndi mtundu wa gasi wamigodi.
- Zida zamagetsi zosaphulika za migodi
Zomwe zimatchedwa kuphulika-zikutanthauza kuyika zigawo zamoyo za zipangizo zamagetsi mu chipolopolo chapadera. Chipolopolocho chimakhala ndi ntchito yolekanitsa zipsera ndi ma arcs opangidwa ndi magawo amagetsi mu chipolopolo kuchokera ku chisakanizo chophulika kunja kwa chipolopolo, ndipo chimatha kupirira kuphulika komwe kumapangidwa pamene chisakanizo chophulika chomwe chimalowa mu chipolopolocho chimaphulika ndi zipsera ndi ma arcs a zida zamagetsi mu chipolopolo, pamene chipolopolocho sichikuwonongedwa, ndipo panthawi imodzimodziyo, chingalepheretse zinthu zophulika mu chipolopolo kuti zisafalikire ku chisakanizo chophulika kunja kwa chipolopolo. Chigoba chapadera chimenechi chimatchedwa chipolopolo chosayaka moto. Zipangizo zamagetsi zokhala ndi chipolopolo chosayaka moto zimatchedwa chipangizo chamagetsi chamoto.
- Kuonjezera chitetezo zipangizo zamagetsi migodi
Mfundo yotsimikizira kuphulika kwa chitetezo chowonjezereka cha zida zamagetsi ndi: kwa iwo omwe akugwiritsira ntchito zida zamagetsi zomwe sizingapange ma arcs, sparks ndi kutentha koopsa pansi pazikhalidwe zogwirira ntchito, kuti apititse patsogolo chitetezo chawo, njira zingapo zimatengedwa mu kapangidwe kake, kupanga. ndondomeko ndi luso la zipangizo, kuti apewe zida kupanga cheche, arcs ndi kutentha koopsa pansi ntchito ndi zinthu mochulukira, ndi kukwaniritsa magetsi kuphulika-umboni. Kuwonjezeka kwa zida zamagetsi zotetezedwa ndikuchitapo kanthu kuti zithandizire chitetezo chake potengera momwe zida zamagetsi zidakhalira, koma sizitanthauza kuti zida zamagetsi zamtundu uwu zimakhala ndi magwiridwe antchito abwinoko kuposa zida zina zamagetsi. Mlingo wachitetezo chachitetezo chowonjezereka cha zida zamagetsi zamagetsi sizitengera mawonekedwe a zida zokha, komanso kukonza malo ogwiritsira ntchito zida. Zida zamagetsi zokhazo zomwe sizipanga ma arcs, sparks and overheating panthawi yogwira ntchito bwino, monga zosinthira, ma motors, zowunikira, ndi zina zotere, zitha kupangidwa kukhala zida zamagetsi zotetezedwa.
- Zida zamagetsi zotetezeka kwambiri pamigodi
Mfundo yotsimikizira kuphulika kwa zida zamagetsi zotetezedwa mwachilengedwe ndi: pochepetsa magawo osiyanasiyana amagetsi amagetsi, kapena kutenga njira zodzitchinjiriza kuti muchepetse kutulutsa mphamvu ndi mphamvu ya kutentha kwa dera, kuphulika kwamagetsi ndi kutentha komwe kumachitika pakugwira ntchito moyenera komanso Zolakwika zomwe zafotokozedwa sizingayatse chisakanizo chaphulika m'malo ozungulira, potero kumapangitsa kuti magetsi asawonongeke. Dongosolo la zida zamagetsi zamtunduwu palokha limakhala ndi magwiridwe antchito oletsa kuphulika, ndiko kuti, "ndizotetezeka", motero amatchedwa otetezeka mwakuthupi (apa amatchedwa otetezeka). Zida zamagetsi zomwe zimagwiritsa ntchito mabwalo otetezeka kwambiri zimatchedwa intrinsically safe electronic equipment.
- Zida zamagetsi zamagetsi zabwino
Mfundo yotsimikizira kuphulika kwa zida zamagetsi zamagetsi ndi: zida zamagetsi zimayikidwa mu chipolopolo chakunja, ndipo palibe gwero la mpweya woyaka moto mu chipolopolo; chipolopolocho chimadzazidwa ndi mpweya woteteza, ndipo kupanikizika kwa gasi wotetezera mu chipolopolo ndipamwamba kuposa kupanikizika kwa malo ozungulira ozungulira, kuti ateteze kusakaniza kophulika kwakunja kulowa mu chipolopolo ndikuzindikira kuphulika kwa magetsi. zida.
Chizindikiro cha zida zamagetsi zamagetsi ndi "p", ndipo dzina lonse la chizindikirocho ndi "Expl".
- Zida zamagetsi zodzaza mchenga zopangira migodi
Mfundo yotsimikizira kuphulika kwa zida zamagetsi zodzaza mchenga ndi: lembani chipolopolo chakunja cha zida zamagetsi ndi mchenga wa quartz, kuyika magawo oyendetsa kapena magawo amoyo pazida pansi pa quartz sand explosion-proof filler layer, kuti pamikhalidwe yodziwika. , arc yopangidwa mu chipolopolo, lawi lofalikira, kutentha kwapamwamba kwa khoma lakunja kwa chipolopolo kapena pamwamba pa mchenga wa quartz sikungathe kuyatsa kusakaniza kozungulira kozungulira. Zipangizo zamagetsi zodzaza mchenga zimagwiritsidwa ntchito pazida zamagetsi zokhala ndi voliyumu yosapitilira 6kV, yomwe magawo ake osuntha samalumikizana mwachindunji ndi chojambulira chikagwiritsidwa ntchito.
