Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the embodiment of the present invention provides a method for a suspended rail vehicle to cross the non-electric zone of a turnout, which is applied to a DC-powered suspended rail vehicle, including: before the vehicle crosses the non-electric zone, generate a first-level position command and send it to the traction system, so that the traction system turns off the traction device and the electric braking device according to the first level command; after the vehicle passes through the no-electric zone, a second level command is generated and sent to the traction system, so that the The traction system resumes normal traction and braking according to the second level command.

[0026] Specifically, in thi...

Abstract

The invention provides a method and device for a suspension type railway vehicle to pass through a turnout non-electric area, and relates to the technical field of suspension type railway vehicles. The method for the suspension type rail vehicle to pass through the turnout non-electric area is applied to the direct-current power supply suspension type rail vehicle and comprises the steps that before the vehicle passes through the non-electric area, a first-level instruction is generated and sent to a traction system, and therefore the traction system can close a traction device and an electric braking device according to the first-level instruction. According to the technical scheme, the traction device and the electric braking device are closed before the vehicle passes through the non-electric area, arc discharge caused by the fact that the vehicle passes through the non-electric area with a traction load is prevented, and the situation that traction blocking is caused by overheat protection of a chopper resistor of a traction box due to the fact that braking energy cannot be fed back when the vehicle is electrically braked in the non-electric area is prevented. Therefore, the situation that the vehicle cannot be self-started after passing through the non-power area is avoided, and the vehicle can smoothly pass through the non-power area.

Description

technical field [0001] The invention relates to the technical field of suspended rail vehicles, in particular to a method and device for a suspended rail vehicle to pass through a non-electric zone of a turnout. Background technique [0002] Suspended rail transit is a new type of traffic system, and its infrastructure is quite different from traditional rail transit. There are many forms of track turnouts, such as movable type and translation type, and it may be inconvenient to install power supply rails inside the turnout, which causes the suspended rail vehicle to pass through the dead zone. Due to the existence of the dead zone, the suspended rail vehicle must perform necessary protection actions in the dead zone to prevent the large arc from damaging the current receiver and the power supply rail when crossing the dead zone, and also to prevent the arc generated when passing through the dead zone. Damage caused by high current to the vehicle. Contents of the inventio...
