Description

Technical Field

[0001] This invention relates to the field of transformer lightning protection technology, and specifically to a lightning protection device for a 10kV transformer. Background Technology

[0002] Transformer lightning protection refers to a series of technologies and measures to protect transformers from damage caused by lightning overvoltages. Lightning is a powerful natural phenomenon. When lightning strikes a power system directly or occurs nearby, it generates extremely high voltages. These voltage waves can intrude into the transformer along the transmission lines, posing a great threat to the transformer's insulation system and potentially causing insulation breakdown, damage, or destruction of the transformer.

[0003] When a transformer is in operation, it may attract nearby lightning during thunderstorms, which could damage the device. Therefore, it is necessary to install lightning protection devices on the transformer to ensure its normal operation. Summary of the Invention

[0004] The purpose of this invention is to provide a lightning protection device for a 10kV transformer in order to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a lightning protection device for a 10kV transformer, comprising a transformer body, wherein a lightning protection component is provided on the top of the transformer body; A top insulation plate is installed on the top of the transformer body; Electronic component boxes are provided at both ends of the transformer body; The transformer body is provided with heat dissipation components on both sides, and the heat dissipation components include heat dissipation fins and heat dissipation fans located at the bottom of the heat dissipation fins. The transformer body is provided with a mounting base at its bottom, and the mounting base includes multiple sets of mounting beams and a fixed mounting base plate; The lightning protection component includes a lightning rod mounting base, on which a lightning rod bottom insulating plate and multiple lightning rod mounting positions are provided, and a lightning rod is provided in one of the lightning rod mounting positions.

[0006] Preferably, the top insulating plate has downward-curved arc-shaped structures on both sides.

[0007] Preferably, the electronic component box is provided with mounting brackets on both sides, the mounting brackets are "L" shaped, the mounting brackets are welded to the transformer body and fixedly connected, and the electronic component box is fixedly installed to the mounting brackets by bolts.

[0008] Preferably, the transformer body and heat dissipation components are located below the top insulating plate.

[0009] Preferably, multiple sets of mounting beams are evenly distributed at the bottom of the transformer body, and the fixed mounting base plate is located at the bottom of the mounting beams.

[0010] Preferably, the mounting beam is welded to the bottom of the transformer body, and the fixed mounting base plate is welded to the mounting beam.

[0011] Preferably, the fixed mounting base plate is provided with fixed mounting screw holes, and the fixed mounting base plate is perpendicular to the mounting beam.

[0012] The beneficial effects of this invention are: 1. By installing a top insulation plate on the top of the transformer body, current and voltage can be effectively prevented from being transmitted to the transformer body, thereby reducing the impact of lightning strikes on the transformer body; 2. The combination of heat dissipation fins and bottom cooling fan allows for rapid airflow and dissipation of heat inside the transformer body, thus accelerating heat dissipation efficiency; 3. By setting the top insulation plate as an arc-shaped structure with both sides curving downwards, rain and snow can slide off quickly in rainy or snowy weather, preventing them from accumulating.

Electronic component boxes 2 are respectively provided at both ends of the transformer body 1, and electronic components are respectively installed inside the two electronic component boxes 2. Heat dissipation components are provided on both sides of the transformer body 1, and the heat dissipation components include heat dissipation fins.
