Ibhokisi lokusabalalisa liyingxenye ebalulekile yohlelo lokuphakela amandla, elibhekele ngokuyinhloko ukufaka, ukukhipha, ukusabalalisa, nokuvikela amasignali kagesi, amanje, kanye ne-voltage, ukuqinisekisa ukusebenza okuphephile nokuthembekile kohlelo lukagesi. Okulandelayo ezinye izicaciso ezijwayelekile zobuchwepheshe zamabhokisi okusabalalisa:
1. I-voltage elinganisiwe: Lokhu kubonisa amandla kagesi aphezulu ibhokisi lokusabalalisa elingamelana nawo, ngokuvamile angu-380V noma ama-220V (ezinto ezisetshenziswayo zasendlini).
2. Isilinganiso samanje: Lokhu kubonisa inani eliphezulu lamanje ibhokisi lokusabalalisa elingamelana nalo, ngokuvamile elingu-20A, 30A, 50A, 100A, njalo njalo.
3. Isilinganiso sokuvikela: Lokhu kukhombisa izinga lokuvikela elihlinzekwa yibhokisi lokusabalalisa, elivame ukuhlukaniswa njenge-IP20, IP40, IP54, noma IP65, okubonisa amazinga ahlukene okuvikela.
4. Izinga lokushisa le-ambient elisebenzayo: Lokhu kubonisa ububanzi bezinga lokushisa elingaphakathi lapho ibhokisi lokusabalalisa lingasebenza ngokujwayelekile, ngokuvamile phakathi kuka- -25℃kanye no-+40℃.
5. Umthamo wezintambo: Lokhu kubonisa umthamo omkhulu wezintambo zebhokisi lokusabalalisa.
6. I-Nominal Short{1}}Ikhono Lokuhlukana Kwesekethe: Lokhu kubonisa amandla{2}}okunqamuka kwesekethe we-shunt kanye ne-fuse uma kwenzeka iphutha{3}}elifushane.
7. I-Arc Withstand Time: Lokhu kubonisa ubude besikhathi sokungqubuzana okubangelwa ukuphazamiseka kokuxhumana kwesikhashana. Lokhu ngokuvamile kusetshenziselwa ukuhlola ukusebenza kokuphepha kwebhokisi lokusabalalisa.
Kafushane, lokhu okungenhla kukhona imingcele evamile yobuchwepheshe yamabhokisi okusabalalisa. Izinhlelo zokusebenza ezihlukene zidinga amapharamitha wobuchwepheshe ahluke kancane, ngakho abasebenzisi bangakhetha ngokuya ngezidingo zabo ezithile.
