17.5kV Ring Main Unit

Kufotokozera Kwachidule:

Gulu lalikulu la SS lopangidwa ndi gasi, compact ring main unit ndi SF6 gas-insulated medium-voltage switchgear yopangidwa ndi Seven Stars Electric. Chogulitsacho chimatenga mawonekedwe osinthika omwe amatha kukonzedwa mosasamala malinga ndi mapangidwe osiyanasiyana ndipo ndi kuphatikiza koyenera kwa bokosi wamba ndi gawo lowonjezera, lomwe limatha kukwaniritsa zosowa zamagawo osiyanasiyana achiwiri kuti agwiritse ntchito compact switchgear.
Zida za switchgear za SS ndi makina osindikizidwa kwathunthu, okhala ndi magawo onse amoyo ndi masiwichi otsekeredwa m'mipanda yazitsulo zosapanga dzimbiri. Iwo sakhudzidwa ndi zochitika zachilengedwe ndipo amapereka ntchito yodalirika. Zogulitsazo zimadziwika ndi mawonekedwe ophatikizika, ntchito yopanda kukonza, komanso moyo wautali, zomwe zimakwaniritsa zofunikira pakugwirira ntchito mkati ndi kunja. Zogulitsazo zadutsa chiphaso cha mayeso amtundu wa High Voltage Apparatus Testing Center ndipo amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana kuphatikiza magawo ogawa, ma switchgear amtundu wa bokosi, mabizinesi amakampani ndi migodi, ma eyapoti, njanji, malo ogulitsa, nyumba zapamwamba. , misewu ikuluikulu, njanji zapansi panthaka, ngalande, ndi mkhalidwe woipa wa chilengedwe.

★maola 24 pafupifupi kutentha kwakukulu: +35°C
★Chinyezi: Chinyezi chapakati chapakati (muyezo wa maola 2 4) 95%
Kuchuluka kwa chinyezi chachibale (muyezo wa mwezi umodzi) 90%
★ Pankhani yoyika popanda kuchepetsa kuthamanga kwa gasi: kutalika kwake ndi 1500 m
Seven Stars SS series- switchgear ntchito panja:
★Utali:≤4000m
★Kutentha kozungulira: kutentha kwakukulu: +50 °C; Kutentha kwapakati mkati mwa 24h sikudutsa +35 ° C
★Chinyezi chozungulira: 24h chinyezi chachifupi sichidutsa 95%; Chinyezi chapakati pamwezi sichidutsa 90%
★Malo oyika: mpweya wozungulira umakhala wopanda mpweya wophulika komanso wowononga, ndipo palibe kugwedezeka kwamphamvu pakukhudzidwa kwa malo oyika, mulingo woipitsa sudutsa THE lll. mlingo mu GB/T5582;
★Kuthamanga kwa nthaka komwe kumachitika chifukwa cha zivomezi: pansi pa njira yopingasa. 3g, Molunjika pansipa. 15g pa

PRODUCT STRUCTURE DIAGRAM

Seven Stars SS mndandanda- Mapangidwe a mphete ali ndi mawonekedwe ophatikizika mpaka mayunitsi 4 omwe amatha kukonzedwa ngati tanki imodzi yophatikizika popanda kulumikizana kulikonse.
ili ndi zosinthira zonyamula katundu komanso zopumira zotchingira / s zodzaza ndi gasi wa SF6 mkati mwa thanki yachitsulo chosapanga dzimbiri yomwe imaphatikizidwa ndi mpanda wa lP54
Kapangidwe kameneka kamalola kuti pakhale malo ochulukirapo opangira chingwe chosavuta (750 mm kuchokera ku bushings kupita ku chingwe cholumikizira) ndi m'lifupi mwa chipinda cha chingwe 400 mm.
Ndipo nthawi yomweyo kusunga kutalika kwabwino kwa makina ogwiritsira ntchito ndi chipinda chowongolera
