Title:
ELECTRICALLY-DRIVEN FRACTURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/155065
Kind Code:
A1
Abstract:
An electrically-driven fracturing system is disclosed. The system comprises a main power generation device (100), a first auxiliary power generation device (200), a switch device (300), and an electrically-driven fracturing device (400). The switch device comprises a low-voltage switch group (310) and a high-voltage switch group (320); the electrically-driven fracturing device comprises a fracturing motor (420) and a fracturing auxiliary device (410); rated power generation power of the main power generation device is greater than that of the first auxiliary power generation device, and a rated output voltage of the main power generation device is greater than that of the first auxiliary power generation device; the high-voltage switch group comprises an input end and an output end, the low-voltage switch group comprises an input end and an output end, the input end of the high-voltage switch group is connected to the main power generation device, the output end of the high-voltage switch group is connected to the fracturing motor, the input end of the low-voltage switch group is connected to the first auxiliary power generation device, and the output end of the low-voltage switch group is connected to the fracturing auxiliary device. According to the electrically-driven fracturing system, system down caused by power-off or faults of the power generation device can be avoided, power supply safety is improved, and damage to equipment is reduced.
