Electric phase separation self-actuated switching control device used for pantograph passing neutral section

Abstract

The invention discloses an electric phase separation self-actuated switching control device used for an electrified railway pantograph passing neutral section. The electric phase separation self-actuated switching control device is formed in a manner that an online phase separation section is connected with a switching control compartment by high-voltage cables 18, 19 and 20, wherein the switching control compartment is arranged at a line side. As the online phase separation section forms symmetrical power supply delay process sections L1 and L2, linked power supply sections L8 and L9, switching limit process sections L6 and L7 and pantograph envelope sections L3 and L4 capable of meeting requirements of any speed zones and any pantograph rectification manners, signal acquisition contact lines 5 and 6 are lapped by utilizing a pantograph, control signals are provided by signal acquisition units 16 and 17, program control is performed on working conditions of normally-opened switches 21 and 22, a normally-closed switch 23 and a resistor 25 by a control system 26, and all functions required by the pantograph passing neutral section are automatically completed on line. The pantograph passing neutral section problem is completely solved by a contact network, and an effect that the passing neutral section is irrelevant to driving is achieved. The electric phase separation self-actuated switching control device used for the electrified railway pantograph passing neutral section is suitable for any zones, speed zones, locomotive crews or motor train units and pantograph rectification manners, and has the characteristics that the safe reliability is high, the service life is long and the operation cost-effectiveness is low.

Description

technical field [0001] The invention relates to an automatic electrical phase separation device for the catenary for electrified railway pantograph over-phase separation, especially the problem of over-phase separation of the pantograph caused by the segmental phase-separation power supply of the catenary, which can be completely solved by the catenary itself Electric split phase self-changing control device. Background technique [0002] There are two existing technologies that are closest to the present invention at present, the "electric phase-splitting automatic switching device" of Hitachi Corporation of Japan and the "phase segmentation automatic switching device" of Xi'an Science Research Institute, according to the Science and Technology Information Institute of the Ministry of Railways ( 95) Xin Yan Zi No. (037) "Research on Traction Power Supply System for High-Speed ​​Railways Abroad" and "High-Speed ​​Electrified Railway" published by Southwest Jiaotong Universit...

Problems solved by technology

Its common shortcomings: the overall structural form of equipment integration in multiple departments, the equipment of each department must cooperate and coordinate with each other to complete all the functions required by the phase division, and the responsibility for failure is unclear, which is not conducive to systematic maintenance and management , safety and reliability are difficult to guarantee; special locomotives are required, and both locomotives need to be modified, which affects the scope of application; the beginning and end of the signal collection area are not the actual positions of the first and last bows of the train, the signal collection method is not reasonable enough, and the signal position is not accurate; switch Equipment such as equipment and control systems not only occupy the space in the facility, but are easily restricted by environmental conditions, and the investment cost is large, the service life is short, and the operation efficiency is high, which is difficult for users to accept.
