Technical Field

[0001] The utility model relates to the technical field of transformer box devices, in particular to a transformer box with a protective structure. Background Art

[0002] A transformer substation is a box that transforms, concentrates, and distributes the voltage and current of electric energy in a power system. To ensure the quality of electric energy and the safety of equipment, voltage adjustment, flow control, and protection of transmission and distribution lines and major electrical equipment are also required in the substation. Since transformer substations are installed outdoors and are easily damaged, they need to be protected to increase their service life.

[0003] At present, the existing utility model can install the mounting plate on both sides of the transformer box body by screws, and at the same time, through the action of the spring inside the fixing rod, it can play a buffering role when the protective plate is hit by the outside. The setting of the protective plate can play a good protective role for the transformer box body used outdoors, avoiding damage to the transformer box body caused by external reasons and affecting the use, and the setting of the warning strip can also play a good warning role at night, thereby improving the protective effect of the transformer box body. Through the work of the electric push rod, the slider will move inside the moving groove, so that the moving plate connected to the connecting plate will move outside the transformer box top. A scraper is set on the lower surface of the moving plate, so that the transformer box top can be cleaned by the scraper when the moving plate moves, so as to avoid dust or pollutants falling on the transformer box top and affecting the service life of the transformer box body.

[0004] For example, the authorization number CN219498635U discloses an outdoor transformer box with a protective structure, wherein protective mechanisms are symmetrically arranged on both sides of the transformer box body, and the protective mechanisms include mounting plates installed on both sides of the transformer box body by screws, and a protective plate is arranged on one side of the mounting plate; a cleaning mechanism is slidably arranged on the outside of the transformer box top, and the cleaning mechanism includes a moving plate slidably installed on the outside of the transformer box top, and a scraper is arranged on the lower surface of the moving plate on the upper surface of the transformer box top.
