Nzira Yokusarudza Sei Kudzivirirwa Kwakakodzera Kwematatu Echikamu Chekudzivirira?

Ndakamborasikirwa nebhodhi reCNC remadhora zviuru makumi mana ($40,000) nekuti ndakadarika SPD yemadhora mazana maviri ($200). Kuruma ikoko kwakandidzidzisa kusarudza rakakodzera.

Ndinosarudza SPD ine zvikamu zvitatu nekutarisa Uc, In, Imax, Iimp, Up, housing, uye certificates. Chigadziko ichi chinofanira kuenderana nemagetsi esystem yangu, kubata surge yangu yakaipa, uye kukodzera panel yangu.

Ramba uchiverenga uye ndichakuratidza runyoro rwandinopa kune wese mutengi anondikumbira mutengo.

Chii chinonzi 3 Phase Surge Protector?

Ndinotumira zviuru zvemabhokisi aya mwedzi wega wega, asi vatengi vazhinji vachiri kundibvunza kuti chii chiri mukati.

Chidziviriro che surge chezvikamu zvitatu ibhokisi resimbi rine varistors dzesimbi-oxide nemachubhu egasi. Rinofambisa magetsi akawanda pasi kuitira kuti surge isasvike kumamota angu, madhiraivha, kana maPLC.

Mazita andinoita zvikamu zviri mukati

Ndinovhura imwe yemayuniti edu eLeikexing pabhenji rangu. Uchaona varistor nhatu kana ina dzakasungirirwa pakati peL1-L2, L2-L3, L3-L1, uye mutsetse wega wega unoenda pasi. Fuse diki inodziya inogara padhisiki yega yega yevaristor. Kana dhisiki ikapisa zvakanyanya, fuse inovhurika uye mureza mutsvuku unobuda. Mureza uyu unondipa chiratidzo chekuona nekukurumidza chekuenda/kusaenda pandinofamba mumutsara wepaneru.

Sei ndichisarudza 3+1 mode yezvirimwa zvakawanda

Mutengi wangu wekuGerman anoshandisa ma network e400 V TN-S. Anoraira 3+1 mode: varistors nhatu dze line-to-line uye imwe ye N-PE. Iyi mode inondipa dziviriro yakaenzana pa phase ne neutral. Dai ndakashandisa 3-mode chete, neutral-to-earth surge inogona kugogodza PLC yake. Mari yekuwedzera ye $8 yakachipa pane awa imwe chete yekuzorora.

Maitiro andakaita kuverenga zita racho mumasekonzi gumi

Ndinodzidzisa vatengi kuverenga chinyorwa chakaiswa mubhokisi. Tsvagai nhamba shanu idzi:

Kana paine nhamba isipo, ndinokumbira mutengesi kuti andipe bepa rekuyedza. Hapana bepa, hapana kutenga.

Mudziyo wekudzivirira kukwira kweropa wezvikamu zvitatu unoshanda sei?

Ndichiri kuyeuka kekutanga pandakaona 40 kA ichikwira pa oscilloscope. Mhepo yemagetsi yaikwira seroketi.

SPD yangu yezvikamu zvitatu inoshanda seswichi inokurumidza. Kana voltage yemutsara yakwira pamusoro pechikamu chayo checlamp, resistance yevaristor inodonha kubva pa mega-ohms kuenda ku ohms mumasekonzi mashoma. Inopfupisa kukwira kwesimba remagetsi kuenda pasi uye inodzokororwazve kana voltage yadzoka payakajairika.

Mutsetse we clamp wandinodhirowa kune vatengi
