Title:
INTEGRATED STEP-DOWN POWER SUPPLY DEVICE AND WELL SITE POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/036670
Kind Code:
A1
Abstract:
The present invention aims to provide a step-down power supply device, comprising: a first switch cabinet used for receiving an alternating current having a first voltage and controlling connection and disconnection between the first switch cabinet and a power grid; a transformer used for receiving the alternating current from the first switch cabinet, reducing the voltage of the received alternating current to a second voltage, and outputting the second voltage; a second switch cabinet used for receiving the second voltage from the transformer and outputting the second voltage; and a heat sink used for performing centralized heat dissipation on at least two of the first switch cabinet, the transformer and the second switch cabinet, wherein the first voltage is higher than the second voltage. According to the present invention, the size of the step-down power supply device can be reduced while the heat dissipation efficiency is improved.
