Njengamanje, indlela yokulinganisa yokumelana nebhethri yangaphakathi isetshenziswa kakhulu embonini. Kuzinhlelo zokusebenza zezimboni, ukulinganisa okunembile kokumelana kwangaphakathi kwebhethri kufinyelelwa ngemishini ekhethekile. Ake ngikhulume ngendlela yokulinganisa ukumelana nebhethri kwangaphakathi esetshenziswa embonini. Njengamanje, kunezindlela ezimbili eziyinhloko zokulinganisa ukumelana kwangaphakathi kwebhethri embonini:

1. I-DC yokukhipha indlela yokulinganisa ukumelana kwangaphakathi
Ngokwefomula ephathekayo ethi r=u/I, okokusebenza kokuhlola kuphoqelela ibhethri ukuthi lidlule i-DC enkulu engaguquki yamanje ngesikhathi esifushane (ngokuvamile amasekhondi angu-2-3) (okwamanje kusetshenziswa amandla amakhulu angu-40a-80a) , kanye ne-voltage kuyo yonke ibhethri ikalwa ngalesi sikhathi , Futhi ubale ukumelana kwamanje kwangaphakathi kwebhethri ngokuya ngefomula.
Le ndlela yokulinganisa inokunemba okuphezulu. Uma ilawulwa kahle, iphutha lokunemba kokulinganisa lingalawulwa ngaphakathi kuka-0.1%.
Kodwa le ndlela inezinkinga ezisobala:
(1) Amabhethri amakhulu kuphela noma ama-accumulators angakalwa. Amabhethri anamandla amancane awakwazi ukulayishwa nge-current enkulu ye-40A kuya ku-80A phakathi kwamasekhondi angu-2 kuya kwangu-3;
(2) Uma ibhethri idlula umsinga omkhulu, ama-electrode ngaphakathi kwebhethri azohlukaniswa, futhi i-polarization izoba yingozi, futhi ukumelana kuzovela. Ngakho-ke, isikhathi sokulinganisa kufanele sibe sifushane kakhulu, ngaphandle kwalokho inani lokumelana elilinganiselwe lizoba nephutha elikhulu;
(3) Umthamo ophezulu odlula ebhethrini uzolimaza ama-electrode angaphakathi ebhethri ngokwezinga elithile.
2.Ukucindezela kwe-AC kwehla isilinganiso sokumelana kwangaphakathi
Njengoba ibhethri empeleni lilingana nesiphikisi esisebenzayo, sisebenzisa imvamisa engaguquki nomsinga ohleliwe kubhethri (njengamanje imvamisa ye-1kHz ne-50mA encane yamanje isetshenziswa), bese isampula amandla ayo, ngemuva kochungechunge lokucubungula njengokulungiswa nokuhlunga, Bala ukumelana kwangaphakathi kwebhethri ngokusebenzisa isekethe ye-amplifier yokusebenza. Isikhathi sokulinganisa ibhethri sendlela yokulinganisa ukumelana nokwehla kwamandla kagesi we-AC sifushane kakhulu, ngokuvamile sicishe sibe ngu-100ms. Ukunemba kwale ndlela yokulinganisa nakho kuhle kakhulu, futhi iphutha lokunemba kokulinganisa ngokuvamile liphakathi kuka-1% -2%.
Izinzuzo kanye nokubi zale ndlela:
(1) Cishe wonke amabhethri, kuhlanganise namabhethri amancane, angalinganiswa ngendlela yokulinganisa ukumelana nokwehla kwamandla kagesi we-AC. Le ndlela ivamise ukusetshenziselwa ukukala ukumelana kwangaphakathi kwamaseli ebhethri encwajana.
(2) Ukunemba kokulinganisa kwendlela yokulinganisa ukwehla kwamandla kagesi we-AC kuthinteka kalula yi-ripple current, futhi kunethuba lokuphazanyiswa kwamanje okuvumelanayo. Lokhu ukuhlola ikhono lokulwa nokuphazamiseka kwesekhethi yensimbi yokulinganisa.
(3) Le ndlela ngeke ilimaze kabi ibhethri ngokwalo.
(4) Ukunemba kwendlela yokukala ukwehla kwamandla kagesi we-AC kuphansi kunalokho kwe-DC okukhipha indlela yokukala ukumelana kwangaphakathi.
