Problems solved by technology

The experimental device disclosed in the above documents can only simulate the static contact and separable electrical contact between the pantograph slide plate and the contact wire, but cannot simulate the sliding electrical contact between the pantograph slide plate and the contact wire
Moreover, the experimental device disclosed in this document can only provide high-voltage power supply (25Kv or above). For the study of pantograph-catenary electrical contact, in order to simulate the situation that a large current passes through the panto-catenary contact point, the experimental device needs to be able to provide a large current (1000A above)

Abstract

The invention discloses a bow net electric contact simulation experiment apparatus. The apparatus comprises a contact network, a pantograph, two supports used for installing the contact network, a mobile dolly, a load box arranged on the dolly and a heavy current generating device used for providing power for the whole simulation experiment apparatus. The heavy current generating device, the contact network, the pantograph and the load box are connected in series so as to form an electrical loop. The contact network comprises a contact wire and a suspension structure. The pantograph comprises a slide plate and a support structure. An internal portion of the dolly is provided with a stepping motor used for driving the dolly to move horizontally. A current controller, a pantograph controller and a dolly controller are connected to a master control computer through a network or an on-site bus communication interface. The experiment apparatus is constructed by the pantograph and the contact network, can provide a heavy current to carry out an experiment and can support three kinds of static, slide and detachable electric contact forms.

Description

technical field [0001] The invention relates to the technical field of simulation experiment devices for electric locomotives and trains, in particular to a pantograph-catenary electrical contact simulation experiment device. Background technique [0002] In electrified railways and urban rail transit systems, electric trains use pantographs to obtain electrical energy from the overhead catenary. Pantograph can be divided into single-arm bow and double-arm bow, both of which are composed of pantograph slide plate, upper frame, lower arm rod (lower frame for double-arm bow), bottom frame, bow spring, transmission cylinder, supporting insulator, etc. components. [0003] The pantograph is installed on the top of the carriage, and the pantograph slide plate keeps sliding contact with the contact wire that provides electric energy during the train running. The two subsystems, pantograph and catenary, are coupled together through pantograph-catenary contact force to form an int...
