Ukumelana nokufakwa kwe-insulation kwe-motor kuyipharamitha eyinhloko yokuhlola ukusebenza kwayo kwe-insulation, okuhlobene ngqo nokusebenza okuphephile kwemoto. Ngenxa yezinhlobo ezahlukene kanye namazinga kagesi wamamotho, amazinga amancane okumelana nokufakwa kwe-insulation nawo ahlukile.
Ukumelana ne-insulation yama-motor aphansi-voltage
Ngoba i-low-voltage motors enamazinga kagesi angu-400V nangaphansi, amazinga amancane okumelana nokushisa ami kanje:
Imigqa esanda kubekwa: Ukumelana nokufakwa phakathi kwemigqa naphakathi kwemigqa nomhlaba akufanele kube ngaphansi kwama-megohms angu-0.5.
Izinto zokusebenza nemigqa esebenzayo: Ukumelana nokufakwa kwe-insulation akufanele kube ngaphansi kwe-1 megohm/kilovolt, noma kulingane no-1 kiloohm/volt.
Ukumelana ne-insulation yama-motor amancane naphakathi
Kumamotor amancane naphakathi nendawo, izinga eliphansi lokumelana nokufakwa kwe-insulation nalo alikho ngaphansi kwama-megohms angu-0.5. Leli zinga lisebenza kumishini nemigqa esebenzayo, futhi ukumelana nokufakwa kwe-insulation akufanele kube ngaphansi kuka-1MΩ/kV.
Ukumelana ne-insulationhigh-voltage kagesi motors
Izidingo zokumelana nokufakwa kwama-insulation motors ane-voltage ephezulu ziqine kakhulu. Amazinga athile ami kanje:
Ukumelana nokufakwa kwe-Stator: Ekushiseni kokusebenza, ukumelana nokufakwa kwe-insulation akufanele kube ngaphansi kwe-1 megohm ngekhilovolthi ngayinye.
Ukumelana nokufakwa kwe-rotor: Ukumelana nokufakwa kwayo akufanele kube ngaphansi kuka-0.5 megohms ngekhilovolthi ngayinye.
Ukulinganisa ukumelana nokufakwa kwezimoto
Uma empeleni kukalwa ukumelana nokushisa kwenjini, kungase kube khona umehluko othile ngenxa yereferensi yamazinga ahlukene kanye nomthelela wezici ezifana nezinga lokushisa nokumuncwa kwesilinganiso. Ikakhulukazi lapho inani lokumelana nokufakwa kwe-insulation kanye nesilinganiso sokumuncwa kuseduze nenani elibalulekile, imiphumela yokuhlolwa yama-opharetha ahlukene ingase yehluke. Ngakho-ke, lapho kulinganiswa, imithethonqubo efanele kufanele ilandelwe ngokuqinile, ithuluzi elifanele kufanele likhethwe, futhi izidingo zomkhawulo ezihlukene zezifunda ezibandayo nezishisayo kufanele zihlukaniswe.
Kafushane, izinga elincane lokumelana nokufakwa kwenjini lincike ezingeni layo le-voltage kanye nohlobo. Ukumelana nokufakwa kwe-insulation motors low-voltage motors amancane naphakathi nendawo/i-medium voltage induction motor ngokuvamile kudingeka ukuthi kungabi ngaphansi kwama-megohms angu-0.5, kuyilapho ukumelana nokufakwa kwama-motor-voltage aphezulu akufanele kube ngaphansi kwe-1 megohm ngekhilovolthi ngayinye. Lawa mazinga ahloselwe ukuqinisekisa ukuthi imoto ngeke ibangele izingozi zokuphepha ngenxa yokungangeni ngokwanele ngesikhathi sokusebenza.
