Description

Technical Field

[0001] The utility model relates to the field of high-voltage power engineering, in particular to a protective device for a high-voltage power transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. When the transformer is installed outdoors, the terminals and wires on the transformer are exposed. The connection between the wires and the terminals is easily corroded by rain or other objects from the outside, causing damage to the connection, affecting the normal use of the transformer. A transformer protection device with publication number CN220155318U was found in the patent office database. Although it can protect the connection between the wires and the terminals, making the connection less susceptible to erosion by rain or other objects, and the protection device is easy to install and disassemble, and easy to transport, the heat dissipation fins on the side of the transformer cannot protect it, and the heat dissipation holes are too small, making it inconvenient to quickly open them to dissipate heat from the transformer in summer.
