Chidziviriro cheMagetsi paBhokisi reMagetsi Chinokonzera Matambudziko Here Kana Kuti Chinopa Dziviriro?
Ko Mudziviriri weKukwira pa Bhokisi reMagetsi Kukonzera Matambudziko Here Kana Kuti Kunopa Dziviriro?
Ndakamboona mutengi achirasikirwa ne30 K USD kamwe chete. Munhuwi wemotokari dzakapiswa uchiri kundimutsa husiku.
Chidziviriro che surge chakaiswa papaneru hachikonzeri dambudziko kana ukasarudza voltage yakakodzera wobva warega tekinoroji ine rezinesi ichiisa. Chinocheka spike isati yabva pachigadziko chemita, kuitira kuti michina yako igare yakachengeteka.
Pazasi ndinotsanangura zvese zvatakambotaura nevatengi vakaita saJeff gore rapfuura. Ramba uchiverenga uye uchaziva kuti sei tichiisa mabhokisi madiki aya mukabati rega rega rinobuda mufekitori yedu yeWenzhou.
Chii chinonzi Surge Protector paElectric Box?
Ndichiri kuyeuka nguva yekutanga yandakabata imwe. Yaitaridzika semuchina wakakora wekudzikisa magetsi, asi chikwangwani chakanyorwa kuti “SPD 40 kA”. Ndakabvunza mukuru wangu webasa kuti, “Chinhu ichi chinongova chinja chemhando yepamusoro here?”
Chidziviriro chemagetsi chinoiswa pamagetsi chinoshandiswa nesimbi chinoisa waya zvakananga kubhazi guru. Chinotora kana kutsausa magetsi akawandisa mumasekondi asingasviki makumi maviri nemashanu, saka simba rekuwedzera harisviki kumabreaker ako.
Kusiyana Kwayo Nesimba Remagetsi
Vatengi vazhinji vanosanganisa zvinhu zviviri izvi. Chishandiso chemagetsi chiri padyo nedhesiki rako uye chinokupa nzvimbo dzakawanda dzekubuda nadzo. Chishandiso cheSPD chiri mukati mekabati resimbi uye chinochengetedza nzvimbo yese. Chishandiso ichi chinogona kumira pa1 kA. Chishandiso chedu chebhokisi chinotanga pa20 kA uye chinokwira kusvika ku200 kA. Mukana iwoyo mukuru kana dutu rikaitika.
Mukati meBhokisi
Vhura rimwe chete wobva waona mabhuroko matatu esimbi. Rimwe bhuroko ivaristor. Rinodya spike. Rechipiri ichubhu yegesi. Rinopfuta kana spike yacho yakakura zvakanyanya. Chechitatu ifuse. Rinofa saka mamwe ese anorarama. Vese vatatu vanogara paDIN rail uye vanotora nzvimbo nhatu chete. Nzvimbo diki iyoyo inochengetedza chirimwa chose.
Nhamba Dzechokwadi kubva kuLabhoritari Yedu
Takarova spike ye6 kV pabhodhi rekuyera. Voltage parutivi rwemutoro yaingova 420 V chete apo SPD yaivepo. Pasina iyo, mutoro mumwe chete waiona 2 850 V. Madhiraivha mazhinji aikundikana pa1 800 V. Tafura inoratidza mukaha.

Mudziviriri weKuputika Anoshanda Sei?
Ndaimbofunga kuti zvaive zvemashiripiti. Ipapo mainjiniya wedu akandiratidza girafu imwe chete iri nyore. Mutsetse mutsvuku ndiwo mupendero. Mutsetse webhuruu ndiwo mupendero. Pavanosangana, mupendero unofa.
Chishandiso ichi chinotarisa sine wave. Kana voltage ikasvetuka pamusoro pe1 100 V, inopfupisa tambo kuti iburuke kwemasekondi mashoma. Simba rakawedzerwa rinoshanduka kuita kupisa mukati mevaristor. Wave inodzokera ku230 V uye PLC yako haimbooni kusvetuka.
Matanho Matatu Atinoshandisa muWenzhou
Tinovaka magiredhi matatu. Chikamu chekutanga chinogara pamita. Chikamu chechipiri chinogara pachikamu chidiki. Chikamu chechitatu chinogara padivi pekutyaira.

Nei Kumhanya Kuchirova Saizi
Varistor hombe inoita kunge yakasimba, asi kumhanya kunokunda. Chip yedu itsva ye25 ns inokunda block yekare ye100 ns ka4. Mupata wacho unonzwika mudiki, asi dhiraivha inogona kuvharira mu50 ns. Kumhanya kwakachengeteka.
Zvidziviriro zveKuputika Zvinokonzera Matambudziko Here?
MunaKurume wadarika mutengi akanditumira tsamba achiti, “Jason, SPD yako yakapisa bhazi rangu.” Ndakaenda kunzvimbo iyi nendege ndikawana mugadziri webhazi akashandisa 120 V unit pamutsetse we277 V. Bhazi racho rakafa ndokutora bhazi racho.
Chidziviriro che surge hachizokonzere zvikanganiso kana uchienzaniswa ne voltage, short-circuit current, uye saizi ye waya. 90% yematambudziko emunda anobva pakuiswa zvisiri izvo, kwete chikamu.
