The invention belongs to the technical field of lightning protection transformers and relates to an outdoor application-oriented transformer with a lightning protection function. The outdoor application-oriented transformer with the lightning protection function comprises a bottom plate and a top plate; two transformers are arranged between the bottom plate and the top plate; a lightning arresteris arranged between the bottom plate and the top plate; the lightning arrester is located between the transformers at the two sides; damping devices are uniformly arranged at the top of the top plate;and a standby conductive plate is arranged at the tops of the damping devices. According to the outdoor application-oriented transformer with the lightning protection function of the invention, mainconductive poles are adopted, and the main conductive poles are matched with the lightning arrester, and therefore, long-time lightning protection is carried out; when the main conductive poles are damaged accidentally, for example, the rod bodies of the main conductive poles are fractured, and the arc ball bodies of the main conductive poles are damaged, or a main conductive plate fails to realize lightning protection because the main conductive plate is damaged by lightning, temporary lightning protection can be carried out through standby lightning rods, the standby conductive plate and a standby grounding lead, and therefore, the lightning protection effects of the transformers in strong wind days are guaranteed, and influence on the use of an electric appliance caused by the damage ofthe transformers which is further caused by lightning stroke can be avoided.
Description
technical field [0001] The invention relates to the technical field of lightning protection transformers, in particular to an outdoor transformer with lightning protection function. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It is widely used in the power construction industry. However, when the existing transformer encounters thunderstorms, it often encounters lightning strikes, resulting in a rapid rise in the power voltage, resulting in transformers and In order to avoid the damage of electrical appliances, lightning rods or lightning arresters are widely used on the top of transformers for lightning protection. However, thunderstorms are often accompanied by strong winds. For this reason, lightning rods are prone to be affected by strong winds. Under the environment, it is constantly under stress, which leads to a decrease in the service life of the lightning rod. Therefore, it ...
