Embodiment 2

[0052] Embodiment 2. The difference between embodiment 2 and embodiment 1 is that only a finisher room and a DC switch room are provided in the cabinet, and the AC incoming line busbar is arranged between the DC switch room and the rectifier room to reduce AC input. The space occupied by the line busbar and the rear space of the rectifier room can be used to install other devices.

Embodiment 3

[0053] Embodiment 3. The difference between embodiment 3 and embodiment 1 is that the secondary equipment room and the DC switch room can also be set up and down in layers, making full use of the height space at the position of the DC switch room.

Abstract

The present invention relates to a traction rectification switch device in the field of substations and a traction substation using the traction rectification switch device. The traction rectificationswitch device comprises a cabinet body, a mounting frame for setting a rectifying device side by side in a vertical direction is arranged in the cabinet body, the cabinet body is internally providedwith a DC switch chamber for the insulating isolation of the rectifying device along a side perpendicular to a plane where the mounting frame is located, and a DC isolating switch is installed in theDC switch chamber. An input side of the rectifying device is connected to an AC wire inlet bus, an output side is connected to the DC isolating switch through a DC busbar, and a DC isolating switch chamber supplies power to a traction locomotive through a DC feeder cabinet. Compared with the prior art, the rectifying device and the DC isolating switch are integrated in the same cabinet body, the switch device has the advantages of compact structure, convenient operation and maintenance and high safety and reliability, the volume of the rectification switch device is greatly reduced, and the floor space of the traction substation is reduced, and the investment cost of substation construction is reduced.

Description

technical field [0001] The invention relates to a traction rectification switchgear in the field of substations and a traction substation using the switchgear. Background technique [0002] With the country's new urbanization construction centered on regional urban agglomerations and central cities, in order to solve the traffic pressure caused by population growth, public transportation such as subways, light rails, and trams have become the only way to solve urban traffic problems. The decentralization of approval authority for trams has stimulated the enthusiasm of domestic third-tier cities to build rail transit projects. Traction substations are used to supply power for urban rail transit. For example, a subway traction power supply system disclosed in the Chinese utility model patent with the notification number CN206452103U includes a rectifier cabinet and a DC switch cabinet. The important equipment in the system, most of the rectifier cabinets and DC switchgears in...
