DC1500V three rail plane arrangement structure
Technical field
The utility model relates to a kind of plane arrangement structure that is applicable to subway DC1500V three rail electric power systems.
Background technology
The floor plan of subway DC1500V three rail electric power systems and the safe reliability of engineering have directly gets in touch, and also is subjected to the restriction of factors such as gauge, tunnel structure and comprehensive pipeline simultaneously.Because of adopting first in China, its floor plan does not have corresponding experience to use for reference for the DC1500V third rail system, and state's external schema is different inapplicable because of power supply voltage.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of later-model DC1500V three rail plane arrangement structure are provided, and can be applicable to the metro construction of China better, satisfies the needs of metro operation, improves the safety and the reliability of engineering simultaneously.
For achieving the above object, the technical solution of the utility model is as follows: DC1500V three rail plane arrangement structure, three rails of arranging along route are arranged, this route comprise at least the elevated line section, a kind of in lower curtate, special sector and the station section; Select different arrangement structures according to different sections, three rails of elevated line section are installed on the right side of train direct of travel; Three rails of ground lower curtate are installed on the left side or the right side of train direct of travel; Three rails of the special sector layout of taking to change sides; Three rails of station section are arranged in the opposite of platform.
Above-mentioned special sector comprises track switch.
The utility model is by adopting said structure, and requirement is runed in the driving that makes DC1500V three rail electric power systems can satisfy subway fully, improves the safety and the reliability of system simultaneously, reduces accident probability.
Description of drawings
Fig. 1 is the plane arrangement structure scheme drawing of lower curtate station, the ground DC1500V of place three rails;
Fig. 2 is the elevated line section station DC1500V of place three rail floor plan pattern diagram;

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
The specific embodiment
DC1500V three rails are arranged along underground route, and are selected different arrangement structures according to different sections.
At the elevated line section, three rails are arranged in the right side of train direct of travel.
At the ground lower curtate, three rails are arranged in the left side or the right side of train direct of travel.
As depicted in figs. 1 and 2, at the station of underground or elevated line section, three rails 1 are arranged in the opposite of platform 2.
As shown in Figure 3, at special sectors such as track switches, three rails 1 adopt the arrangement structure of changing sides.
