| 成果简介 | NOVELTY - Invention relates to power supply lines for vehicles. Method of control over circuit breakers of catenary lines of double-track section of alternating current of traction power supply consists in the fact that at moment of short circuit in traction network according to accelerated protection with device for comparison of absolute values of currents in contact circuits of even and odd paths on one half-zone the circuit breaker with highest short-circuit current is determined and it is accepted as emergency. Short-circuit control device is used to determine the presence or absence of short-circuit in the contact system, and if the short-circuit has been eliminated, a command is given from the short-circuit control device to block the disconnection circuit of the controlled station disconnectors. Maxi-selector determines the highest current of one of the controlled disconnectors of the sectioning post of one line of the contact system of the half-zone, if it is determined that short circuit has not been eliminated, then according to the maximum current of the maxi-selector of one line of the contact network, the half-zone of the inter-substation zone is disconnected only one controlled disconnector of this line during the current pause, and then switches of the traction substations are switched on according to the standard automatic reclosure, except for one – the emergency one. USE - Vehicles. ADVANTAGE - Simplification of disconnector switching process. 1 cl, 1 dwg |
