Title:
VEHICLE-MOUNTED DIRECT-CURRENT POWER SUPPLY APPARATUS AND FRACTURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/088424
Kind Code:
A1
Abstract:
A vehicle-mounted direct-current power supply apparatus (100). The apparatus is arranged on a carrier vehicle and comprises a high-voltage input unit (110), a rectification unit (120) and an output control unit (130), which are respectively provided with a protection cabinet, wherein the high-voltage input unit (110) is arranged on a chassis portion of the carrier vehicle, and is used for executing a voltage reduction operation on an external input power supply and outputting a voltage, which has subjected to voltage reduction, to the rectification unit (120); the rectification unit (120) is arranged on a gooseneck portion of the carrier vehicle, and is used for executing a rectification filtering operation on the voltage input from the high-voltage input unit (110), so as to form a plurality of paths of direct-current power sources; and the output control unit (130) is arranged between the gooseneck portion and chassis portion of the carrier vehicle, and is used for outputting the plurality of paths of direct-current power sources outward. The situation where a power supply apparatus having a skid-mounted design needs to be subjected to unloading, transferring and hoisting operations on site is avoided, and the problems of a large occupied area and a large number of occupied vehicles as a result of power supply apparatuses which are designed on a one-to-one basis are solved.
