Abstract
This utility model relates to an inverter anti-islanding protection device, belonging to the field of inverter technology. It includes an inverter anti-islanding protection device body and four air inlet pipes fixedly installed on the device body. Each of the four air inlet pipes has a limiting ring fixedly connected inside. A connecting ring is placed on the front of each of the four limiting rings. A filter screen is fixedly connected inside each of the four connecting rings. Each of the four air inlet pipes has two mounting slots on its front, and contact plates are placed inside each of the eight mounting slots. This inverter anti-islanding protection device filters the air through the filter screen, minimizing dust entry into the device body and improving protection effectiveness. The gap fit between the positioning rod and the positioning hole allows for convenient fixing of the connecting rings, facilitating easy disassembly, replacement, and cleaning of the filter screen, making it more convenient and practical.
