Product Description

Iyo inodzivirira capacitor yakabatana mukuenderana neiyo vacuum switch.Kana iyo vacuum switch yakabatana kune inductive mutoro, haingogone kudzikamisa iyo yekushanda overvoltage kune imwe nhanho, asi zvakare inonoke kusimuka nguva yekucheka-kubvisa overvoltage uye re-ignition overvoltage wave musoro uye kuderedza kukwira, nekudaro. kudzivirira iyo Midziyo yemagetsi inodzivirirwa kubva pakukanganiswa kwemateru ekumberi.
Inoshandiswa mu50Hz, 3kV, 6kV, 10kV, 35kV magetsi masisitimu kuti iite inopikisa-capacitance absorber ine resistor.Inoshandisa simba rinotorwa ne capacitor kudzikisa voltage amplitude uye damping mhedzisiro ye resistor kuti attenuate oscillation uye kudzivirira overvoltage.Iyo yekugadzika modhi yeyakarerekera poindi inogumira kuti ive nechokwadi chekuti inoenderana neiyo insulation level yemota uye inovandudza kunaka kwemagetsi emagetsi grid.
Mune zvimwe zviitiko, inogona zvakare kushandiswa seyakakwira-voltage capacitor.Kana yakabatana pakati pemitsetse nepasi, inogona kuderedza overvoltage yemhepo, kukwira kwewavefront uye peak-to-peak value.
Inogona kuchengetedza midziyo yemagetsi kana yakashandiswa nemusungwa;Iyo inoenderana capacitor yeRC overvoltage absorption mudziyo wevacuum wedunhu breaker system.

Technical parameters uye chiyero chechimiro

■ Kuita kwehunyanzvi
● Capacitance deviation: -5%~+10%.
● Dielectric kurasikirwa tangent kukosha tanδ
Pasi rated voltage Un, pa20 ℃:
A. Yefirimu-bepa rinosanganiswa media: tanδ≤0.002.
B. Yepakati yefirimu yakazara: tanδ≤0.0005.
● Rated frequency: fn = 50Hz.
● Iyo capacitor inogona kumhanya kwenguva yakareba pasi pe1.1Un, uye inogona kumira kushandiswa kwepamusoro kwekushanda kunokonzerwa nekuzarura nekuvhara kwevhavha yedunhu neyokutanga peak value ≤2.5 2Un.
● Iyo capacitor inogona kumhanya kwenguva yakareba pasi pe 1.5In, ikozvino ino inosanganisira ikozvino inokonzerwa ne-steady-state overvoltage, inosanganisirawo ikozvino inokonzerwa neharmonics, uye inosanganisirawo ikozvino yakawedzerwa ne capacitance deviation.
● Kutonhorera nzira: zvisikwa convection yemhepo pamusoro pe capacitor shell.
● Kukwirira kwekuisa uye nzvimbo yekushanda haifaniri kudarika 1000m;iyo ambient tembiricha yemhepo yekumisikidza uye nzvimbo yekushanda: mukati -40～+45 ℃;mhepo hama humidity ≤95%.
● Nzvimbo yekuisa uye yekushanda inofanira kunge isina gasi rinoparadza uye chiputi;hapana conductive kana guruva rinoputika uye yakanyanya mechanical vibration.
●Hakufaniri kuva neguruva rakawanda uye tsvina pamusoro pechiso checeramic sleeve ye capacitor.Kana kubuda kwemafuta kunowanikwa, kushanda kunofanirwa kumiswa.

Zvigadzirwa zvechigadzirwa uye chiyero chekushandiswa

Iyo capacitor inonyanya kuumbwa negoko uye musimboti.Goko racho rakasungirirwa nendiro yesimbi yakatetepa, chivharo chine wire outlet porcelain sleeve, uye mativi ese emadziro akasungwa neAngle mahwendefa ekuiswa.Iyo musimboti inounganidzwa kuita yakazara nechikamu, insulating chikamu uye yakasimba hoop, uye chikamu chepakati chinoputirwa ne electrode yakaparadzaniswa nayo.
Yepamusoro-yemhando yepamusoro uye yepamusoro-inoshanda insulating zvinhu zvinosarudzwa seyakasimba midhiya, uye yakakosha yepamusoro-vacuum evaporation process inoshandiswa kufefetedza simbi kuumba chaiyo mota chimiro.Iyo inogadzirwa kuita capacitor unit pamushini wekutenderedza otomatiki, uye wozoitwa capacitor ine patented tekinoroji, uye wozoshandiswa munhevedzano ine yakakosha isiri-inductive resistor.

Mamiriro ekushanda:

1. Ambient tembiricha yemhepo: -40～+45℃, hunyoro husingapfuuri 95%.
2. Hapana gasi rinopisa uye mhepo munzvimbo yekuisa, hapana guruva rinoputika kana rinoputika uye kudengenyeka kwakaoma kwemagetsi.
3. Kuisa nzira: vertical installation.
