Inkampani yethu inamandla obugcisa owomeleleyo, itekhnoloji ephezulu, inkqubo yolawulo egqibeleleyo, izixhobo zokuhlola umgangatho opheleleyo, kunye nemveliso eyomeleleyo ye-R & D kunye nomthamo wemveliso. Ukuthobela intanda-bulumko yeshishini "ejolise kwintengiso, umgangatho wobomi, ulawulo njengesiseko, isayensi kunye netekhnoloji kuqala, ejolise ebantwini", inkampani ikhuthaza inkcubeko yeshishini lokuthembeka, ukwenza izinto ezintsha, ukusebenza kakuhle kunye nokuvisisana, ikhonza uluntu ngomgangatho ophezulu- iimveliso ezisemgangathweni kunye namaxabiso afanelekileyo, kwaye ihlangabezana neemfuno ezahlukeneyo zabathengi. Umda woshishino wale nkampani usasazwa kuwo onke amanqanaba eegridi zamandla kunye neeprojekthi zamandla amakhulu e-China, kwaye ibonelela ngomgangatho ophezulu we-silicone yerabha ehlanganisiweyo yokugquma ukuxhasa iimveliso kubenzi bezixhobo zombane ezidumileyo kumazwe ngamazwe.

2, Ukwaziswa kwemveliso

I-Fcrgj glue efakwe eludongeni lwe-fiber capacitive bushing ngokuthe ngcembe inciphisa amandla ombane aphezulu ngomgaqo wokwahlula amandla ombane. Ekusebenzeni okuqhelekileyo, isiphelo sesikrini sokugqibela silingana neflange kwaye sisekelwe kwi-flange. Ukuze i-high-voltage lead ikwazi ukudlula eludongeni okanye umgangatho ngokukhuselekileyo kwaye idlale indima yokugquma kunye nokuxhasa ukuphambuka.

Yenziwe ngokujija okuphambili, i-sheath yangaphandle, isiketi seambrela yerabha ye-silicone, isigqubuthelo esilinganayo soxinzelelo kuzo zombini iziphelo, i-flange kunye ne-conductive wire clamp.

3. Ukutyhoboza eludongeni

Umzekelo, intsingiselo ye-fcrgj-24 / 3150: irabha efakwe kwi-fiber capacitive wall bushing ene-voltage elinganisiweyo ye-24kV kunye ne-rerated current ye-3150A.

Intsingiselo ye-fcrgj-252 / 2500: iglue efakwe kwi-fiber capacitive wall bushing ene-voltage elinganisiweyo ye-252kV kunye ne-2500A yangoku.

4. Iimeko zokusetyenziswa:

1. Iimeko zomoya we-Ambient: ubushushu bomoya we-ambient: ubuninzi be-55 ℃, ubuncinane - 60 ℃.

2. Ukukhethwa komgama othile we-creepage kuya kuhambelana nemimiselo ye-GB / T 5582.

Umgama othile weCreepage wahlulwe ngokwamanqanaba ama-4:

Iklasi I: 16mm / kV; Udidi II: 20mm / kV; Udidi III: 25mm / kV; IBakala IV: 31 mm / kV

Iphutha elivumelekileyo elibi elivumelekileyo lomgama we-creepage wangempela we-bushing ngu-0.04l + 1.5mm (L: ubuncinane bomgama we-creepage).

Xa umsebenzisi engenazo iimfuno, ukungagqibeki yi-31mm / kV

5, Iiparamitha eziphambili zobugcisa bemveliso

1. Itheyibhile 1 inika i-voltage elinganisiweyo, i-voltage yokusebenza kwenkqubo, i-current rated current, i-insulation level kunye nezinye iiparameters ze-fcrgj zodidi lwe-bushing.

2. Phantsi kombane we-1.05ur / √ 3 kunye ne-ur, i-dielectric loss factor TG δ ≤0.4%.

3. Umthamo wokukhutshwa kwendawo: ≤ 5pc phantsi kombane olinganisiweyo we-1.05ur / √ 3.

4. Ukunyuka kobushushu ≤ 60K, ukusebenza kwexesha elide kwi-inom elinganisiweyo yangoku

5. Ubushushu obunganyangekiyo okwangoku: ith = 25inom, 3C

6. Ezinye iimeko zobugcisa ziya kuhambelana nemigangatho ye-IEC 60137-2017 kunye ne-GB / T 4109-2008 i-insulating bushings ene-AC voltage ephezulu kune-1000V.

6, Ukuthutha kunye nokuphakanyiswa

1. Ukuthuthwa kwemveliso

1.1 iimveliso zinokuthuthwa ngololiwe, ngenqanawa, ngemoto, ngenqwelomoya kunye nezinye iindlela zothutho. Ikhompatimenti kaloliwe, indawo yeenqanawa kunye nendawo yemoto ethwele iimveliso kufuneka igcinwe icocekile kwaye ingenazingcolisi.

1.2 ukulayishwa kweemveliso kuya kuhlangabezana neemfuno kwimigaqo yothutho, kwaye iimveliso ziya kubekwa ngokuqinileyo. Akukho kungcangcazela, ukungqubana kunye nokunyakaza kuvunyelwe ngexesha lokuthutha.

1.3 ngexesha lokuthuthwa kwemveliso, ukuthambekela akuyi kuba mkhulu kune-30 °.

1.4 emva kokuba iimveliso zigqithiselwe kwisikhululo sesikhululo okanye zithulwe kwi-terminal, ukupakishwa akusayi kudlula imigangatho emithathu, kwaye ezinye izinto azivumelekanga ukuba zipakishwe kunye nazo.

INHLOKO-UHLOBO-1

I-voltage ephezulu ehambelana ne-capacitor ilungele uqhagamshelo oluhambelanayo kwiinkqubo zamandla ze-AC kunye ne-frequency frequency (50Hz okanye 60Hz) ye-1kV nangaphezulu. Zisetyenziselwa ukubuyisela amandla asebenzayo, ukuphucula amandla ombane, ukuphucula umgangatho wamandla ombane, ukunciphisa ilahleko yomgca, kunye nokusetyenziswa ngokupheleleyo kokuveliswa kwamandla kunye nezixhobo zokubonelela.
