Zusammenfassung: | FIELD: electrical engineering; heavy-power cables. SUBSTANCE: electric cable has insulated conductors one of which is used as neutral conductor shorted out by outside conducting parts; neutral conductor is arranged to meet condition , where a12 is distance between gravity centers of neutral conductor sections and closest phase conductor, mm; P is perimeter of phase conductor cross-sectional area, mm. EFFECT: eliminated danger of neutral conductor overheating in case of reduction in its sectional area due to specific current distribution at single-phase short circuit. 1 dwga |
