Idivayisi yempendulo yamandla ekheshi ye-IPC ithuthukisiwe isuka kumkhiqizo wesizukulwane sesithathu yaya kumkhiqizo wesizukulwane sesikhombisa. Namuhla, eminyakeni eyishumi kamuva, ngemva kokulungiswa okujwayelekile, abaphathi be-Rongchao bathole ukuqonda okubanzi okwengeziwe kwedivayisi yempendulo ye-IPC yesizukulwane sesikhombisa ye-IPC elevator energy ngokwethulwa kwabasebenzi bezobuchwepheshe. Ngemva kokufunda ngokusebenza komkhiqizo wethu, uMnyango Wezobunjiniyela Bezakhiwo waseRongchao nawo uzwakalise ukuzimisela ukuwushintsha ufake umkhiqizo omusha. Idivayisi yempendulo yamandla ye-IPC yesizukulwane sesikhombisa inemiphumela ebaluleke kakhulu yokonga amandla, ukusebenza okuzinzile, nokuphepha okuphezulu. Ukuzinza kanye nomphumela wokonga amandla walo mkhiqizo bekulokhu kuhamba phambili embonini. Ngenxa yokufakwa kwedivayisi yempendulo ye-elevator yamandla, isistimu yokuqala yokubhuleka kanye ne-braking resistor yekhabhinethi yokulawula ikheshi kuyagcinwa, okungeke kuthinteke idivayisi yempendulo, futhi ngesikhathi esifanayo, kwakha isivikelo sokusekela i-elevator braking. Kodwa-ke, ukufaka idivayisi yempendulo yamandla ekheshi akuwushintshi umzila wokuqala wekheshi, ngakho-ke akukona okokulungisa ikheshi!
Ugesi okhiqizwe lapho ilifthi ikhuphuka ingawumthwalo, yehla ngomthwalo osindayo, noma ukuma ezingeni elifanayo ekuqaleni ibisetshenziswa ukushisisa nge-resistor yokubhuleka. Ngenxa yokuxhumana okufanayo phakathi kwedivayisi yempendulo yekheshi kanye nesistimu yokubhuleka edla amandla yasekuqaleni, isistimu yokubhuleka edla amandla idinga u-680V ukuze iqale. Nokho, idivayisi yethu yempendulo iqala ukusebenza ku-640V, iguqule le ngxenye yamandla e-DC ibe yi-AC futhi iyithumele kumjikelezo oyinhloko wekheshi ukuze iphinde isetshenziswe. Eqinisweni, idluliselwa kwelinye ilifti noma imithwalo ezungezile efana nesiphephetha-moya nokukhanyisa, futhi isetshenziswe eduze. Uma idivayisi yempendulo yamandla yekheshi isebenza, isistimu yokubhuleka edla amandla isesimweni sokuyeka ukusebenza; Uma idivayisi yempendulo yamandla yekheshi ingasebenzi kahle, isistimu yokubhuleka edla amandla izoqala ukusebenza, ukuze ingaphazamisi ukusetshenziswa okuvamile kwekheshi.
