Abstract

The invention discloses a control method adopted during passing through a third rail non-electric interval. The control method comprises the following steps that the working conditions of a vehicle are obtained; when the vehicle is under the traction or zero-position working condition, a nest step is executed; when the voltage reduction rate of a middle busbar of the vehicle is up to a preset reduction rate, disconnection of a high-speed circuit breaker is controlled; a traction invertor is controlled to disconnect a short-circuit contactor; when it is detected that the voltage of the middle busbar is recovered to reach a normal value, the high-speed circuit breaker is closed. The invention further discloses a control system used during passing through the third rail non-electric interval. In addition, the invention further discloses an electrical vehicle provided with the control system. By the adoption of the control method, the middle busbar of the vehicle is prevented from suffering from larger impact current, and it is effectively ensured that the vehicle smoothly pass through the third rail non-electric interval.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a control method for passing through a third-rail non-electric section. The invention also relates to a control system for passing through the non-electric section of the third rail; in addition, the invention also relates to an electric vehicle with the control system. Background technique [0002] Urban rail transit using the third rail power supply generally has more non-electrical sections for insulation and breaking, and the length of the non-electrical sections generally ranges from 2 to 40 meters. The power supply of urban rail vehicles will be temporarily interrupted when passing through the non-electric zone. At present, there are no known effective measures to effectively solve the problem of passing through the non-electric zone. [0003] In order to ensure the continuity of its power supply and flow, the electric passenger car generally uses its multi-car fixed forma...
