1. Chii chinonzi anArc Mhosva Yakachengetedzwa Circuit Breaker(AFDD)?
Nekuda kwekusabatana kwakashata kana kukuvara kwekudzivirira, iyo "yakaipa arc" ine simba rakawanda uye tembiricha yakakwira inogadzirwa munharaunda yemagetsi, izvo zvisiri nyore kuwanikwa asi zviri nyore kukonzera kukuvara kwemidziyo uye kunyange moto.
Mamiriro ezvinhu anowanzoita kukanganisa arcs
Fault arc, inowanzonzi electric spark, tembiricha yepakati yakakwira zvakanyanya, simbi spatter inoitika, nyore kukonzera moto.Kana parallel arc ikaitika, waya mhenyu uye waya isina kwayakarerekera haina kutarisana zvakananga, chete nekuti iyo yekuvhara ganda kuchembera inorasikirwa nehunhu hwekudzivirira kana kukuvara kweganda, asi chinhambwe pakati pewaya mhenyu uye mutsara wakasarudzika uri padyo, uye ikozvino. inotyora mhepo pakati pewaya mhenyu netambo isina kwayakarerekera, uye pfarivari dzinobuda pakati pewaya mhenyu netambo isina kwayakarerekera.
2. Yakajairika maitiro e low-voltage fault arc:
1. Ikozvino waveform ine yakawandisa high-frequency ruzha
2. Pane kudonha kwevoltage pane fault arc
3. kukurumidza kusimuka kwezvino kunowanzo kuve kwakakura kupfuura mamiriro enguva dzose
4. Yese hafu yenguva kune nzvimbo iyo ikozvino iri pedyo ne zero, iyo inonzi "ikozvino zero area".
5. Voltage waveform iri padyo nerectangle, uye chiyero cheshanduko munzvimbo ino zero yakakura kupfuura iyo pane dzimwe nguva, uye iyo yepamusoro ndeye kana ikozvino yadarika zero.
6. fault arc inowanzoita sporadic, intermittent
7. Ikozvino waveform ine yakasimba randomness
Kudzivirira uye kutonga kwemoto wemagetsi, iyo ndiyo yekutanga njodzi yemoto, iri kuwedzera uye yakakosha.Arc Fault circuit breaker (AFDD), arc kudzivirira switchgear inodzivirira moto wemagetsi pakutanga, inodiwa.AFDD- arc fault circuit breaker, inozivikanwawo searc fault yekuona mudziyo, imhando nyowani yemidziyo yekudzivirira.Inogona kuona kukanganisa kwearc munharaunda yemagetsi, uye kugura dunhu pamberi pemoto wemagetsi, uye zvinobudirira kudzivirira moto wemagetsi unokonzerwa nearc kukanganisa.
3. Ndedzipi nzvimbo dzekushandisa dzeAFDD arc fault circuit breaker?
Arc fault circuit breaker operation mechanism, circuit breaker system, blurt out institution, inspection function keys, terminal blocks, shell frame, senge general structure, hunhu hwayo hunosanganisira magetsi ega ega bvunzo dunhu, magetsi ega emagetsi ekuona akajairika dunhu ( kusanganisira microprocessor), sisitimu yekumisikidza uye kugadzirisa kwakavakirwa paPCB ant colony algorithm, Takura pane yakangwara yemagetsi ega bvunzo, iyo yakajairika mhosva yemagetsi yega kusarura.
Yakasiyana-siyana mashandisiro makuru pasina bofu nzvimbo yakawanda yekuchengetedza chinhu
AFDD arc fault circuit breaker inoshandiswa zvakanyanya munzvimbo dzine vashandi vakaomerwa uye zvinhu zvinopisa zvinopisa senge zvivakwa zvekugara, maraibhurari, makamuri emahotera, zvikoro uye zvimwe zvivakwa zvetsika neruzhinji.Yakabatana nemuviri wayo wakareruka uye wakapfava, hupamhi hwese hungori 36mm, iyo inochengetedza zvakanyanya nzvimbo yebhokisi rekugovera, uye inoenderana nenzvimbo zhinji dzekuisa geographical.Iyo inova sarudzo yakanakisa yeyakajairwa yekudzivirira yemagetsi moto monitoring.
