摘要 |
FIELD: railway transport. ^ SUBSTANCE: invention relates to longitudinal supply wire systems of non-traction consumers arranged near ac electrified railways. Proposed high-voltage wire system contains three-phase traction transformer connected with contact system and rail-earth and longitudinal power supply line connected with power consumer through electrical meter and consisting of two wires-phases under electromagnetic influence of contact system. Said line is additionally provided with third wire-phase grounded at substation and three-contact switch designed for simultaneously switching off three wires-phases at system supply cutoff mode. All three wires-phase are arranged on supports of contact system or on separately standing supports from field at equal distance from contact system. Electrical meter is made in form of three-element energy meter one element of which is connected to grounded wire-phase in direction of consumer. Use of proposed system reduces asymmetry of voltages at consumers and provides possibility of use of three-element energy meters and precludes emergency situations owing to no resonance conditions with no power losses for resonance. ^ EFFECT: increased economy of system. ^ 1 dwg |
