Abstract

The invention provides a temporary power supply for a power distribution automatic terminal device. The temporary power supply comprises a device box, wherein a holder is arranged at the rear side of the upper part of the device box; a solar cell panel is hinged at the upper end of the holder; and a drive device for driving the solar cell panel is arranged between the holder and the solar cell panel. Through adoption of the technical scheme, according to the temporary power supply and the method, in a solar cell panel power supply mode, the influence resulting from a territory is very low, the normal working of a power supply terminal device is ensured under exceptional circumstances until line power-cut overhauling is carried out and factory maintenance personnel arrive. The increase of the line power-cut times and a terminal device offline rate resulting from singly processing device hidden troubles such as a PT device fault can be avoided, and the power supply reliability of the line is improved.

Description

technical field

[0001] The invention relates to the field of electrical equipment, in particular to a temporary power supply for power distribution automation terminal equipment and a method for using the same. Background technique

[0002] The existing power distribution automation terminal equipment normally uses PT AC power supply mode. When a line failure occurs or a PT burns out to cause a power outage, it will be temporarily powered by the battery for no more than two days. After the battery runs out of power, the terminal will be offline. And lose all protective functions. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the above defects, provide a temporary power supply for power distribution automation terminal equipment and its use method, reduce the offline rate of power distribution terminals and the number of power outages caused by line equipment failures such as line PTs, and improve power supply ...
