Embodiment Construction

[0017] The electric pantograph control circuit of this embodiment, such as figure 1 As shown, the electric pantograph control circuit is characterized in that it includes: a rising front bow train line 120, a rising middle bow train line 125, a rising rear bow train line 122, a lowering front bow train line 121, a lowering middle bow train line 126, Lowering bow train line 123, lowering bow notification train line 124, wake-up relay COR1, pantograph selection knob switch PCCS with four gears, lifting bow knob switch RLPS, pantograph selection knob switch PCCS has three pairs of input and output Terminals, lifting bow knob switch RLPS has three pairs of normally closed contacts and three pairs of normally open contacts. The three output terminals of the bow selection knob switch PCCS are respectively connected to the front bow control wire 1100E, the middle bow control wire 1100F, and the rear bow control wire 1100G. At points 13 and 14, the forward bow control wire 1100E and ...

Abstract

The invention relates to a control circuit for electrical pantographs. The control circuit comprises seven train lines, a wake-up relay, a pantograph selection knob switch, and a pantograph ascending and descending knob switch. The selection of the pantographs and the execution of the pantograph ascending and pantograph descending are separated in the controlling of the electrical pantographs, and are respectively executed by the pantograph selection knob switch and the pantograph ascending and descending knob switch; the pantograph selection knob switch is arranged in a wall separating cabinet of a driver cab, and is used for selecting a front pantograph, a back pantograph, a middle pantograph and an entire pantograph; and the pantograph ascending and descending knob switch is arranged in a driver desk, and is used for selecting the pantograph ascending and pantograph descending. The driver can select the pantograph needing to act by operating the pantograph selection knob switch according to requirements, and can complete the designated action of the pantographs by operating the pantograph ascending and descending knob switch. The control circuit solves the problem of control of single pantograph and centralized control of three pantographs in a subway vehicle with three electrical pantographs, the control is simple and convenient, the influences on the equipment installation and the operation habits of the driver are avoided, and the additional cost is not caused.

Description

technical field [0001] The invention relates to an electric pantograph control circuit. Background technique [0002] In previous subway projects, two pantographs were generally used for one train. The control method of the electric pantograph generally uses a knob to perform the operation of lifting the bow, which can realize the selection of one or more pantographs and the execution of the pantograph lifting. The specific functions include: [0003] ? Front bow selection and bow raising execution of pantograph; [0004] ? Backbow selection and bow lift execution of pantograph; [0005] ? Pantograph double-bow selection and bow-raising execution; [0006] ? The pantograph lowering operation, no matter how many pantographs are raised, the bow will always be lowered. [0007] Since some subway projects are divided into short-term and long-term planning, for example, the early stage of the project is 4 car formations, and the long-term passenger flow will be expanded to 6 ...
