Overview
Nekunyanya njodzi inokonzerwa ne-lithium-ion bhatiri inoitika, Vanhu vanonyanya kunetseka pamusoro pebheteri yekushisa inomhanya, sezvo kupisa kwemhepo kunoitika mune imwe sero kunogona kuparadzira kupisa kune mamwe masero, zvichiita kuti kuvharwa kwebheteri system yose.
Nechinyakare isu tinokonzeresa kutiza kwekupisa nekudziya, kupinza kana kuwandisa panguva yekuedzwa. Nekudaro, nzira idzi hadzigone kudzora kutiza kwekupisa musero yakatarwa, uye haigone kuitwa nyore panguva yekuyedzwa kwemabhatiri masisitimu. Munguva pfupi yapfuura vanhu vari kugadzira nzira nyowani yekukonzeresa kutiza kwekupisa. Iyo Propagation bvunzo mune itsva IEC 62619: 2022 muenzaniso, uye inofungidzirwa kuti nzira iyi ichave inoshandiswa zvakanyanya mune ramangwana. Chinyorwa ichi ndechekuzivisa dzimwe nzira itsva dziri kutsvagirwa.
Laser Radiation:
Laser mwaranzi kupisa nzvimbo diki ine simba rakawanda laser pulse. Kupisa kuchaitwa mukati mezvinhu. Laser radiation inoshandiswa zvakanyanya munzvimbo dzekugadzirisa zvinhu, senge welding, kubatanidza uye kucheka. Kazhinji kune marudzi e laser sezvinotevera:
- CO2laser: carbon dioxide molecular gas laser
- Semiconductor laser: Diode laser yakagadzirwa neGaAs kana CdS
- YAG laser: Sodium laser yakagadzirwa neyttrium aluminium garnet
- Optical fiber: laser yakagadzirwa negirazi fiber ine isingawanzo pasi chinhu
Vamwe vaongorori vanoshandisa laser ye40W, 1000nm wave kureba uye 1mm dhayamita kuyedza pamaseru akasiyana.
Test zvinhu | Test mhinduro |
3Ah Homwe | Thermal runaway inoitika mushure me4.5 maminetsi laser kupfura. Chekutanga 200mV inodonha, wozodonha voltage ku0, ukuwo tembiricha inokwira kusvika 300 ℃. |
2.6Ah LCO Cylinder | Haikwanise kutanga. Tembiricha inongokwira kusvika ku50 ℃. Inoda imwe yakasimba laser kupfura. |
3Ah NCA Cylinder | Thermal runaway inoitika mushure me1min. Tembiricha inokwira kusvika 700 ℃ |
Kuve neCT scan pane isina kukonzeresa sero, zvinogona kuwanikwa kuti hapana chimiro chesimba kunze kwegomba riri pamusoro. Zvinoreva kuti laser inotungamira, uye yakakwirira-simba, uye nzvimbo yekudziya ndiyo chaiyo. Saka laser inzira yakanaka yekuyedza. Tinogona kudzora shanduko, uye kuverenga iyo yekupinza uye kubuda simba nemazvo. Zvichakadaro laser ine zvakanakira kudziyisa uye pinning, sekumhanyisa kupisa, uye zvakanyanya kudzoreka. Laser ine zvimwe zvakanakira se:
• Inogona kukonzera kupisa kwemhepo uye haizopise masero emuvakidzani. Izvi zvakanaka kune thermal contact performance
• Inogona kukurudzira kushomeka kwemukati
• Inogona kuisa simba shoma uye kupisa munguva pfupi kuti iite kuti kupisa kunopera, izvo zvinoita kuti bvunzo dzinyatso kudzora.
Thermite Reaction:
Thermite reaction ndeyekuita kuti Aluminium iite nesimbi oxide mutembiricha yakakwira, uye aruminiyamu inotamira mualuminium oxide. Sezvo iyo enthalpy yekuumbwa kwealuminium oxide yakadzikira kwazvo (-1645kJ/mol), saka inoburitsa kupisa kwakawanda. Thermite zvinhu zviripo, uye fomula yakasiyana inogona kuburitsa huwandu hwakasiyana hwekupisa. Vatsvagiri saka vanotanga kuyedza ne10Ah homwe ine thermite.
Thermite inogona kukonzeresa kupisa kunotiza, asi iyo yekupisa yekupinza haisi nyore kudzora. Vatsvakurudzi vari kutsvaga kugadzira reactor yekupisa yakavharwa uye inokwanisa kuisa pfungwa pakupisa.
High-simba Quartz Lamp:
Dzidziso: Isa mwenje wequartz wepamusoro-simba pasi pesero, uye paradzanisa sero uye mwenje nendiro. Iyo ndiro inoda kudhirwa negomba, kuitira kuti ive nechokwadi chekuita simba.
Muedzo unoratidza kuti inoda simba rakanyanya uye nguva yakareba kuti iite kuti kupisa kwemhepo, uye kupisa kwakaiswa kwete zvakaenzana. Chikonzero chinogona kunge chiri chekuti mwenje wequartz hausi mwenje wekutungamira, uye kurasikirwa kwakanyanya kwekupisa kunoita kuti zvisaite kukonzeresa kutiza kwekupisa chaiko. Zvichakadaro simba rekuisa harisi chairo. Iyo yakanaka yekupisa yekumhanya bvunzo ndeyekudzora iyo inokonzeresa simba uye yakaderera yekuwedzera kukosha kwekuisa, kuderedza pesvedzero yebvunzo mhinduro. Saka isu tinokwanisa kutora mhedziso yekuti quartz rambi haibatsiri ikozvino.
Mhedziso:
Tichienzanisa nemaitiro echinyakare ekukonzeresa sero thermal runaway (sekupisa, kuwandisa uye kupinda mukati), laser propagation inzira inoshanda, ine nzvimbo diki yekudziya, yakaderera yekuisa simba uye ipfupi trigger nguva. Izvi zvinopihwa kune yakakwirira inoshanda simba rekuisa pane shoma nzvimbo. Iyi nzira yakaunzwa neIEC. Tinogona kutarisira kuti nyika dzakawanda dzichatora nzira iyi mukufunga. Nekudaro inosimudza zvakanyanya kudikanwa pamidziyo yelaser. Inoda yakakodzera laser sosi uye radiation-proof zvishandiso. Parizvino hapana nyaya dzakakwana dzekudziya dzekutiza bvunzo, iyi nzira ichiri kudiwa kuongororwa.
