Uluhlu lwe-induction yokunyibilika kwesithando somlilo
Indawo enempazamo | Failure performance | Izizathu kunye neendlela zokuhlola | isisombululo | |
Ukungaphumeleli kwebreaker | 1. Xa uvala, kukho isandi sokuvula ngaxeshanye | 1. I-breaker circuit breaker i-short-circuited kwaye ayikwazi ukuvalwa (ngokubanzi kubangelwa ukutshiswa kwe-thyristor) | 1. Faka indawo ye-thyristor kwaye ukhangele isiphaluka esifutshane | |
2. Ukulinganisa ukuba isiphelo esiphezulu se-circuit breaker sinombane kwaye isiphelo esisezantsi asinawo umbane | 2. Ukukhutshwa kwe-undervoltage kutshiswa ngaphandle okanye kungavaliwe | 2. Ukuqinisekisa ukuba isixhobo asikho ixesha elifutshane, ungaqala usibophe ngomtya ukuze singakwazi ukugxumeka. | ||
3. Akukho mpendulo kwaye akukho sandi xa amandla ephakama | 3. Ikhoyili ye-shunt ihlala ivaliwe, khangela ukuba i-coil yokuvula inamandla xa ivala | 3. Unokuqhawula intambo kwelinye icala lekhoyili kuqala, sebenzisa ukuvulwa komatshini, uze ukhangele isiphaluka emva kokuba umveliso ugqityiwe. | ||
4. Ukungaphumeleli kwe-thermal relay okanye isenzo | 4. Unokuqhawula ii-terminals ezimbini ze-relay kuqala, kwaye ukhangele emva kokuba umveliso ugqityiwe | |||
5. Ukusilela koomatshini | 5. Jonga ukuba ingavalwa ngesandla, kwaye ukhangele emva kwemveliso | |||
Ukungena komgca ongenayo | 1. Ukuhamba okubangelwa yisekethe emfutshane kunye nokutshiswa kwe-inductor | 1. Qaphela ukuba i-inductor iyatshisa, okanye umgama phakathi kokujika kwekhoyili usondele. | 1. Gqonkqoza kwiikhoyili ezisondeleleneyo, kwaye ufake izinto zokukhusela ukuze zihlukanise | |
2. Burning KP thyristor caused by too few turns | 2. Jonga inani lekhoyili ejikayo ukuze ubone ukuba zimbalwa kakhulu | 2. Faka endaweni yekhoyili enkulu ye-inductance ngexesha | ||
I-KP thyristor ye-12- pulse rectifier string | 1. I-voltage ye-DC enemigangatho emibini ine-swing enkulu engazinzanga, kwaye i-inverter ayikwazi ukuqaliswa | 1. Jonga ukuba isichasi sokulinganisa umbane esilungisiweyo sonakele | 1. Buyisela i-resistor yokulinganisa amandla ombane, kwaye xa isajikajika, unokudibanisa izichasi ezimbini zebhulorho zibe yibhulorho enye. | |
2. View KP SCR | 2. Khangela ukuba i-rectifier kunye ne-anti-parallel diode yonakele | 2. Faka indawo ye-diode | ||
KP SCR | 1. I-breaker circuit ayinakuvalwa (i-top circuit breaker) | 1. Jonga ukuba i-KP SCR itshisiwe na | 1. Faka indawo ye-thyristor | |
2. Ayinakuqala | 2. Check whether the KP thyristor pulse lamps are all on and the brightness is the same | 2. Ukukhanya akufani, ngenxa ye-3,. 4 ibha yokukhangela i | ||
3. Ingxolo iphezulu xa amandla ongeziwe | 3. Khangela ukuba isekethe ye-SCR iqhelekile na | 3. Iingcingo ezimbini zinokudityaniswa okwethutyana kuqala, kwaye iingcingo zinokujongwa emva kokuba imveliso igqityiwe. | ||
4. Khangela ukuba ukuchasana phakathi kwe-rectifier ye-SCR G kunye ne-K kuqhelekileyo (ngokuqhelekileyo i-10-25R), ukuba ayiqhelekanga, khangela ukuba ingxaki yomgca okanye ingxaki ye-SCR | 4. Qhubela kwiSiqendu 3 ngeengxaki zesekethe, kwaye makutshintshwe ingxaki ye-SCR | |||
Air core reactor | 1. Ngenxa ye-inductance encinci efunekayo kwii-reactors ze-series, i-inductors e-hollow isetyenziswa ngokubanzi, enciphisa ubunzima kunye nomthamo, kunye nokunciphisa iindleko zokugcinwa, kuba umgama phakathi kwe-coil ujiko ude kwaye ubukhulu bodonga lwe-tube alukwazi ukuvutha. kunye nokuvuza kwamanzi. Isiganeko | |||
Reactor with iron core | 1. Umlilo wereactor | 1. Ukulinganisa ukuba ukuchasana kwendandatho yethusi ye-reactor kunye nentsimbi yentsimbi ifutshane (xa umgca we-380V, ukuchasana kufuneka kube mkhulu kune-1K) | 1. Hlulisa i-reactor ukujonga ukuba yeyiphi ikhoyili ejikelezayo emfutshane, kwaye uyilungise okanye uyibuyisele | |
2. Ayinakuqala | 2. Observe whether there is water leakage in the reactor | 2. Disassemble the reactor to check which coil is leaking for repair or replacement | ||
3. Uhambo xa amandla anyuswa xa inokuqaliswa | 3. Nciphisa ukukhanya kwangaphakathi ukujonga ukuba kukho isenzeko somlilo | 3. Ukuba akukho zincedisi okwethutyana kwaye i-reactor ineenguqu ezininzi, i-coil ephukile ingasuswa ngaphandle kokuchaphazela ukusebenza komatshini, kwaye inokusebenza okwethutyana de kube sekupheleni kwemveliso. | ||
