[0002] In the low-voltage direct-current power supply technical field, the power supply of the protection, automation, stability, and splitting devices of the substation and power plant is crucial. In the existing low-voltage direct-current system, according to the low-voltage direct-current screen manufacturer's instructions and practical experience, the electrical life of the low-voltage direct-current equipment is usually 10-15 years. When the service life is approaching, the low-voltage direct-current system of the whole station needs to be transformed. However, in the actual situation, the original positive and negative terminal of the power supply of the protection, automation, stability, and splitting devices has only one terminal, which leads to the fact that when the low-voltage direct-current system is replaced without power failure, temporary power supply of the bypass power supply cannot be realized.

[0003] In the related art, when the low-voltage direct-current feeder screen is replaced, if temporary power supply cannot be provided, for the interval of a single set of protection device configuration, the interval needs to be accompanied by the protection of the device power supply inlet for replacement, which not only affects the reliability of power supply, but also increases the difficulty and cost of maintenance. For the interval of double protection configuration, the protection needs to be turned off for replacement of the device power supply inlet, which is large in operation amount and poor in operability.
