Abstract

The invention discloses a bow net electric contact characteristic testing device which comprises a motor, a motor control system, a power transmission system, a drive wheel, a driven wheel, a contact net wire, a contact net wire tension adjuster, a pantograph type current collector and a pantograph type current collector lifting controller, wherein the drive wheel is connected with the driven wheel through the contact net wire in a transmission manner, the contact net wire between the drive wheel and the driven wheel is in a flat state, and the pantograph type current collector is in dynamic contact with the contact net wire under the control of the pantograph type current collector lifting controller. The invention has the advantages that the contact net wire in contact with a bow net contact section is in the flat state and is in flexible contact with the pantograph type current collector; and the tension of the contact net can be adjusted, thus the electric contact state of the bow net can be really reflected.

Description

technical field [0001] The invention relates to a pantograph-catenary electrical contact characteristic test device, which belongs to the technical field of electrified railways. Background technique [0002] The pantograph-catenary relationship is currently one of the bottlenecks restricting the development of my country's high-speed electrified railways. Ensuring good contact between the pantograph and the catenary wire is a key core issue that needs to be solved urgently in the pantograph-catenary relationship. The electric locomotive is in sliding contact with the pantograph slide through the catenary wire, and obtains electric energy from the catenary. With the increase of train running speed, the influence of factors such as the irregularity of the catenary wire, the vibration along the catenary, the vibration of the pantograph bow, and the irregularity of the track will also intensify, making the electrical contact between the pantograph and the catenary Severe deter...
