Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to an intelligent box-type DC traction transformer substation. Background Art

[0002] The DC traction substation is an important part of the electrified traction power supply system, which is mainly used to provide stable and reliable DC power to the electric power. This type of substation usually adopts a modular and integrated design, and installs the substation equipment, control system, cooling system, etc. in one or more standard boxes to meet the needs of railway traction power supply;

[0003] After searching, the Chinese patent disclosed a box-type DC traction substation (authorization announcement number CN210137128U) including a high-voltage equipment box, a rectifier transformer box and a DC and control equipment box arranged in sequence. The high-voltage equipment box includes a first module and a second module that are interconnected. The first module is used to arrange the high-voltage switch cabinet, and the second module is used to arrange the rectifier cabinet and the discharge cabinet; the rectifier transformer box is used to arrange the rectifier transformer; the DC and control equipment box includes a first compartment, a second compartment and a third compartment that are isolated from each other. The first compartment and the second compartment are both used to arrange the distribution transformer, and the third compartment is used to arrange the DC equipment and the control equipment. Although the above patent technology can reduce the difficulty of production and manufacturing through a modular structure, transportation is more convenient, and the risk of hoisting operation is reduced, reasonable segmentation and isolation are used to reduce the scope of accidents, and the space for internal maintenance and repair is guaranteed;

[0004] However, in the actual application of this patented technology, the above-mentioned device cannot intelligently dissipate internal heat when in use.

On the other hand, continued temperature increase can cause equipment damage and even cause safety accidents such as fires, posing a threat to personnel safety and nearby facilities.
