Embodiment

[0060] An interlocking control method for a dual-stream system test line, which is applied to an interlock control system for a dual-stream system test line, and is mainly used in subway test lines. The system is basically as attached. figure 1 , figure 2 Shown: Includes:

[0061] DC load module: used to supply the DC power of the DC bus to the catenary or the contact rail through the first power supply loop, and also used to return the DC power flowing through the catenary or the contact rail to the DC bus through the first return loop;

[0062] In this embodiment, the DC bus bar includes a positive bus bar and a negative bus bar, and is used for providing a DC power of 750V or 1500V.

[0063] The contact rail includes a positive monorail, a ground rail and a negative monorail. The catenary includes static and dynamic catenary. The static adjustment catenary includes the subway static adjustment line and the rails, which are used for the static adjustment of the trains pa...

Abstract

The invention relates to the technical field of rail transit control, and in particular to an interlocking control method for dual-current test lines, which includes the following steps: when selecting DC power supply, close the first switch so that the DC power of the DC bus is supplied to the catenary or contact network. rail; and close the second switch to return the DC power flowing through the contact network or contact rail to the DC bus; when selecting AC power supply, close the third switch to boost the AC power input from the power supply line and supply it to the contact network; and close the fourth switch to return the alternating current flowing through the contact network to the step-up transformer; interlock the third switch of the same type and the first switches corresponding to the contact network and contact rail; The fourth switch of the type, and the second switch corresponding to the contact network and the contact rail respectively perform interlock control. The invention can realize interlocking control of relevant control switches to avoid power supply conflicts in trains and cause train safety accidents.

Description

Technical field [0001] The invention relates to the technical field of rail transit control, and in particular to an interlocking control method for a dual-flow test line. Background technique [0002] With the continuous development of the times, my country's subway track construction is constantly improving, making our travel more convenient and greatly improving safety. In order to further improve the convenience of people traveling in various areas of the province and city, in the future subway construction plan, the number of subway construction is gradually increasing, and the distance is from near to far. It is planned to gradually cover from the provincial capital center to surrounding districts and counties. [0003] At present, most subways use DC power supply because the distance in the urban area is short, the line loss is small, and the speed adjustment is convenient. In the track construction that gradually covers the provincial capital center to surrounding d...
