Special three-phase or DC rigid three-dimensional grid for electrified sliding operation of vehicles

Abstract

The invention relates to a rigidity three-dimensional power grid which comprises a box body steel groove, a plurality of three-phase power supplies, a sliding contactor and an electric connecting component. The three-phase power supplies are all arranged on the box body steel groove and are used for providing power. The three-phase power supplies comprise an insulation cushion layer paved on the box body steel groove, a power supply track paved on the insulation cushion layer and a sliding contactor track shaped like a Chinese character 'ji'. The sliding contactor track shaped like a Chinese character 'ji' is arranged on the power supply track and is used for being connected with the sliding contactor in an abutting mode. The sliding contactor can be connected with any three-phase power supply in an abutting mode in a falling-off mode and slide on any three-phase power supply in an electrically-connected mode, and the sliding contactor is used for conducting power to a vehicle to drive the vehicle to run. The sliding contactor comprises a first sliding contactor contact component, a second sliding contactor contact component and a track-changing power device. The sliding contactor contact components carry out track changing action under driving of the track-changing power device between adjacent three-phase power supplies. According to the rigidity three-dimensional power grid, the application rate of various vehicles which run in a sliding-contact mode in various highways and urban traffic can be improved, and the safety of vehicle sliding-contact running is improved.

Problems solved by technology

The fuel vehicles currently used have serious exhaust emissions and loud voices, which endanger human health and lead to increasing pollution in urban traffic structures.

Compared with fuel vehicles, battery electric vehicles have certain advantages in energy saving and environmental protection, but they still have insurmountable disadvantages. Their limited storage capacity restricts the mileage and the use of heating and air conditioning, and the weight of the battery itself and occupied space has reached the limit, the service life is short, and the storage capacity is decreasing year by year

The battery has its own loss in the process of charging and discharging, and the power is obviously insufficient in the later stage of driving, and it cannot be used up

In addition, after the battery is scrapped, it will also cause secondary pollution.

The trackless electric vehicle improves the battery electric vehicle and uses the erected cable to supply power, but the vehicle is not easy to change the power supply line, the flexibility is not high, and it is mostly used for fixed-line buses, and its popularity is not high

And the cost of erecting power supply cables is high, and it is easy to cause safety hazards, and at the same time affects the landscape above the city

In recent years, there has been some improvement in the technology of trolley electric vehicles, but generally only involves the improvement of the devices, and there is less research on the power supply grid, and it is still not widely used in practice.
