Chidule Chatsatanetsatane cha Zizindikiro Zolakwika za Cable

Mafotokozedwe Akatundu

Chizindikiro cha grounding short circuit cha awiri-mu-one chili ndi nthambi zambiri komanso zolakwika pafupipafupi. Kupeza zolakwika za mzere ndi vuto lalikulu kwa ogwira ntchito yokonza chingwe chamagetsi. Kupeza cholakwika cha nthaka nthawi zina kumatenga theka la tsiku, ndipo ena amachipeza usiku m'mawa, ndipo ena ku Inner Mongolia. Kuti mupeze masiku angapo. Chifukwa chake, kuyika chizindikiro cha cholakwika kungathandize kwambiri kudalirika kwa magetsi, kuchepetsa mphamvu ya ogwira ntchito, ndikufupikitsa nthawi yozimitsa magetsi.

Mawonekedwe:

1. Perekani thandizo ndi zosavuta pothetsa mavuto mukalephera kugwiritsa ntchito chingwe.
2. Malinga ndi kukula kwa katundu wa mzere ndi kufalikira kwa momwe mzerewo ukugwirira ntchito, malo oyenera oyika chizindikiro cha cholakwika amatsimikiziridwa.
3. Pamene mzere ukuyenda bwino, chizindikirocho chimakhala mu mkhalidwe wokonzanso popanda chizindikiro chilichonse.
4. Pamene vuto la short circuit kapena ground fail lichitika mu mzere, chizindikirocho chimatembenuza chokha mbale ya chizindikiro masana ndipo chimakhala chizindikiro chofiira cha alamu; ogwira ntchito yokonza vuto la mzere amatha kupeza malo olakwika malinga ndi momwe chizindikirocho chilili.
5. Nthawi yokhazikika yokonzanso zinthu ku fakitale ndi maola 12 (nthawi yokonzanso zinthu ikhoza kusinthidwa malinga ndi zomwe makasitomala akufuna).
6. Katunduyu amathandiza kwambiri kuthetsa vuto la mzere ndipo n'zosavuta kudziwa komwe vutolo lachitikira.
7. Fupikitsani nthawi yozimitsa magetsi ndikuwonjezera mphamvu zamagetsi.
8. Palibe chifukwa chozimitsa kukhazikitsa kwa chinthucho, zida zaukadaulo zoyikira zimaperekedwa kwaulere, ndipo kusokoneza kumakhala kosavuta.

Mfundo Yogulitsa

Kuzindikira kwafupipafupi: Dera lozindikira limasintha mwadzidzidzi mphamvu yamagetsi ikachitika vuto lafupipafupi, ndipo kusintha kwadzidzidzi kumakhala kwakukulu kuposa mtengo winawake (womwe ukhoza kukhazikitsidwa malinga ndi momwe chitetezo cha relay chimakhalira) mkati mwa nthawi inayake kuti magetsi agwe ndi kuzimitsidwa.
Kuzindikira nthaka kumazindikira kusintha kwa magetsi, ma capacitor currents ndi momwe zinthu zilili pa nthaka, kuzindikira kusintha kwa harmonic, ndi kudziwa bwino ngati nthaka ikuchitika.

15kV 200Achivundikiro choteteza chotetezedwandi gawo lowonjezera la bushing yamoyo. Imapereka chivundikiro choteteza ku bushing yamoyo komanso chivundikiro choteteza fumbi komanso chinyezi cha malo olumikizira opanda chaji.

200Achivundikiro choteteza chotetezedwaikhoza kuyikidwa pa ma bushing a 200A, mabasi ndi zida zopachikira pakhoma. Pamene mabasi ndi ma chingwe olumikizirana asungidwa kuti azigwiritsidwa ntchito powonjezera, ayenera kutsekedwa ndi zipewa zotetezera kutentha za 200A.

kapangidwe ka mankhwala

Chitsulo choteteza kutentha: Njira yapadera komanso ukadaulo wosakaniza umatsimikizira kuti rabala yathu yoteteza kutentha ya EPDM yokonzedwa kale ndi yapamwamba kwambiri.
Gawo lakunja lothandizira mpweya: rabara yoyendetsera mpweya ya EPDM yokonzedwa kale imakwaniritsa muyezo wa IEEE592.
Diso lokhazikika: diso lokhazikika lolumikizidwa ndi gawo lakunja loyendetsa mpweya, lomwe limagwiritsidwa ntchito pokhazikitsa nthaka.
Mphete yogwirira ntchito: Mphete yogwirira ntchito yachitsulo chosapanga dzimbiri yokhala ndi malo omangira masika.

Zolumikizira zamtundu wa European style 630A cross and T-shaped zimagwiritsidwa ntchito makamaka polumikiza switch bus ya ring network cabinet yokhala ndi insulation komanso yotsekedwa bwino, mogwirizana ndi bushing ya switch cabinet, komanso yoyenera mabokosi a nthambi okhala ndi switch. switch cabinet imakhala ndi insulation yonse komanso yotsekedwa bwino, kupewa zolakwika zomwe zimadza chifukwa cha kuwonekera kwamagetsi okwera kwambiri nyengo yoipa. Chogulitsacho chopangidwa ndi busbar ndi D ndi cross joints chimatchedwa busbar system, yomwe ndi njira yabwino kwambiri ya ring network cabinet. Ubwino waukulu ndi: mtengo wotsika komanso magwiridwe antchito odalirika. Kutalika kwa bus bar kumatha kusinthidwa malinga ndi zomwe kasitomala akufuna. D ndi cross connections zitha kupangidwa kukhala zinthu zotetezedwa kapena zosatetezedwa malinga ndi zomwe makasitomala akufuna.
