Chotsukira ma vacuum circuit cha RDV6-12 chamkati chokhala ndi mphamvu zambiri

Tanthauzo la Chitsanzo

Zachilengedwe

a) Kutentha: Max +40C, Min -10C (30C, malo osungira ndi mayendedwe)
b) Kutalika: 2000m. Zofunikira zapadera ziyenera kufunsidwa ndi ife.
c) Chinyezi chofanana: avareji ya tsiku siyenera kupitirira 95%, avareji ya mwezi siyenera kupitirira 90%. Ndipo kuthamanga kwa nthunzi yokhuta kwa tsiku sikuyenera kupitirira 2.2kPa, avareji ya mwezi siyenera kupitirira 1.8kPa. Ndipo mu tsiku lotentha kwambiri, kutentha kumakhala kozizira,
Kuundana kwa madzi n'kovomerezeka.
d) Mlingo wa chivomerezi: osapitirira mlingo wa 8
e) Ikani malo: popanda moto, kuphulika, fumbi, dzimbiri la mankhwala, zoonekeratu

Ntchito yoyambira ndi khalidwe

1. Chipinda chozimitsira mpweya cha Vacuum Arc chimagwiritsa ntchito zinthu zolumikizirana ndi Cu Cr, komanso kapangidwe kake kolumikizana ndi mphamvu ya maginito yotalika yomwe imakhala ndi mphamvu yochepa yowonongeka, Mphamvu ya dielectric yokhazikika imachira mwachangu pambuyo pozimitsira mpweya, kutseka kochepa, kupanga ndi kuswa mphamvu, komanso moyo wautali wamagetsi.
2. Pakati pa ndodo yotetezera kutentha ndi chipolopolo cha ceramic cha chipinda chozimitsira moto cha vacuum arc. Pogwiritsa ntchito rabara ya silicon yamadzimadzi, onjezerani mphamvu yolimbana ndi kugwedezeka. Chikwama cha ambulera chokhala ndi mtunda wautali wokwera pamwamba pa ndodo, kuti chiwongolere mphamvu yolimbana ndi kugwedezeka kwa magetsi ndi kugwedezeka kwa mphezi, chingakwaniritse zofunikira zazikulu zaukadaulo pamalo okwera kwambiri.
3. Njira yogwirira ntchito ndi njira yosungira mphamvu ya Spring yomwe imakonzedwa pa ndege, ili ndi ntchito zosungiramo zinthu pamanja komanso zosungiramo zamagalimoto, kuti ipititse patsogolo kukhazikika kwa ntchito.
4. Njira yotsekera ma circuit iyi imagwiritsa ntchito, yomwe imagwiritsidwanso ntchito ngati njira yokhazikika ya magnetic actuator, njira iyi imachepetsa 60% ya zinthu poyerekeza ndi masika wamba, imachepetsa kuchuluka kwa zolakwika chifukwa cha zinthu zina.

Malo oyeseraMalo ogwirira ntchito

Chotsekera cha circuit cha mtundu wa drawer cha Fig1 mkati mwa mfundo zamagetsi (zoletsa kugwedezeka, kutseka, kudzaza kwambiri)

Magwiridwe antchito a makina onani Table2

Deta yaukadaulo yogwiritsira ntchito makina onani Gome 3.

Chithunzi 2 Chotsukira dera chokhazikika mkati mwa chithunzi chamagetsi

Zindikirani:

1. Ulendo wa ngolo yonyamula katundu m'kabati ndi 200mm

2. Manambala omwe ali m'mabulaketi akuyimira miyeso yonse ya ma circuit breakers okhala ndi current yovomerezeka yoposa 1600A

Chithunzi 3 Fotokozani miyeso ya chotsukira dera cha ngolo yonyamula anthu
