YCM7YV mndandanda zamagetsi pulasitiki mlandu dera wosweka (apa amatchedwa: dera wosweka) ndi oyenera otsika-voteji mphamvu magulu ndi AC 50Hz, oveteredwa kutchinjiriza voteji 800V, oveteredwa opaleshoni voteji 400V ndi pansipa, ndipo oveteredwa ntchito panopa mpaka 800A. Wowononga dera amakhala ndi nthawi yotalikirapo yodutsa motalikirapo, malire anthawi yocheperako pang'onopang'ono, kuchedwa kwanthawi yayitali, kuchedwetsa kwakanthawi kochepa, nthawi yayitali nthawi yomweyo komanso chitetezo chamagetsi. Nthawi zonse, dera

breaker imagwiritsidwa ntchito pakusintha pafupipafupi kwa mabwalo komanso kuyambitsa pafupipafupi

motors. Mndandanda wa ophwanya ma circuit uli ndi ntchito yodzipatula, ndipo chizindikiro chake chofanana ndi "   "

Muyezo: IEC60947-2.

Zinthu zogwirira ntchito

1. Kutentha kwa mpweya wozungulira

a) Mtengo wapamwamba sudutsa +40 ℃;

b) Kutsika kwa malire sikudutsa -5 ℃;

c) Mtengo wapakati pa maola 24 sudutsa +35 ℃;

2. Kutalika

Kutalika kwa malo oyikapo sikudutsa 2000m.

3. Mikhalidwe ya mumlengalenga

Chinyezi chachibale cha mlengalenga sichidutsa 50% pamene yozungulira

kutentha kwakukulu ndi +40 ° C; imatha kukhala ndi chinyezi chambiri chocheperako

kutentha; pamene mwezi pafupifupi kutentha osachepera wa wettest

Mwezi ndi +25 ° C, mwezi uliwonse kutentha kwakukulu kwa mwezi ndi +25 ° C. Chinyezi chachibale ndi 90%, poganizira za condensation yomwe imapezeka pamadzi

mankhwala pamwamba chifukwa cha kusintha kwa kutentha.

4. Digiri ya kuipitsa

Digiri ya 3 yoyipitsidwa, zida zomwe zimayikidwa mu chophwanyira dera zili ndi digiri yoyipa 2.

5. gulu unsembe

Dera lalikulu la wophwanya dera liyenera kukhala gawo loyika III, ndipo gawo lothandizira ndi gawo lowongolera lidzakhala gulu loyika II.

6. Kuyika zinthu.

Zowononga ma circuit nthawi zambiri zimayenera kuyikidwa molunjika, nthawi zambiri ndi mawaya okwera, ndipo mphamvu ya maginito yakunja pamalo oyikapo sayenera kupitirira kasanu kagawo kakang'ono ka geomagnetic mbali iliyonse.
