Description

Technical Field

[0001] The utility model relates to the technical field of substations, in particular to an auxiliary charging device for substations. Background Art

[0002] A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of electricity, and adjusts voltage. It connects power grids of various voltage levels through its transformers. In a substation, various components are required. These devices are of many types, including transformers, switches, four small devices, reactive devices, and other equipment and auxiliary devices, such as surge arresters, insulators, high-voltage bushings, guide wires, grounding devices, secondary equipment, high-voltage DC equipment, etc. These devices are collectively referred to as substation equipment. In order to ensure that the substation can continue to operate during a power outage, a rechargeable battery is installed inside the substation cabinet.

[0003] The patent with the patent announcement number CN206650479U discloses an auxiliary charging device and system, which relates to the technical field of electronic equipment, wherein the auxiliary charging device includes: a battery, a permanent magnet arranged on the inner side of the tire, and a coil group arranged on the fixed part of the vehicle body, so that when the tire is rotating, the coil group can cut the magnetic flux lines in the magnetic field generated by the permanent magnet, and the coil group can generate current in the process of cutting the magnetic flux lines. Since the battery is connected to the coil group, the current flows into the battery in real time to replenish the battery, thereby reducing the number of times the power battery pack charges the battery through voltage conversion, effectively reducing the heat loss in the voltage conversion process, and saving electric energy in the voltage conversion process. The above patent has the following shortcomings: although the patent can reduce the power loss of the substation cabinet during charging, when the substation cabinet is placed outdoors, its charging port may be soaked by rainwater on rainy days, causing the substation cabinet to short-circuit and be damaged. In view of this, we propose an auxiliary charging device for substations. Utility Model Content
