Abstract

According to the direct current socket and the power supply method thereof, a primary winding of an isolation transformer is connected to an external direct current power supply, high-voltage direct current electric energy output by the direct current power supply is directly transmitted to the isolation transformer for voltage reduction processing, and finally low-voltage direct current electric energy meeting user requirements is output to a direct current power supply port. When the direct-current electric appliance takes electricity, the direct-current power supply port only needs to be inserted, the control device can control the operation states of the switching device and the rectifying device in combination with the output direct current output to the direct-current power supply port by the isolation transformer, and therefore power supply control over the direct-current electric appliance is achieved. According to the scheme, the direct-current electric energy is subjected to voltage conversion at the power taking place of the direct-current electric appliance, the direct-current electric energy obtained through conversion does not need long-distance transmission, the problem that large voltage drop is caused in the transmission process is avoided, and the situation that the power supply voltage transmitted to the direct-current electric appliance from the tail end of the power transmission line is lower than the rated voltage value is avoided.

Description

technical field [0001] The present application relates to the technical field of DC power supply, in particular to a DC socket and a power supply method thereof. Background technique [0002] The distributed local energy Internet includes clean and renewable new energy power generation equipment, energy storage equipment, new energy appliances, energy management and control equipment, etc. It is a supply-demand linkage system integrating power generation, power storage, power distribution, and power consumption. In this type of system, new energy power generation provides DC energy, and new energy appliances directly use DC energy for energy storage charging and discharging, that is, the link of AC conversion is canceled, forming a pure DC power generation ecology, and energy utilization efficiency is greatly improved. Ascension is a new green and low-carbon power system. At the same time, in terms of household electricity consumption, household appliances are low-voltage D...
