Abstract

This utility model relates to the technical field of arc flash protection devices. It provides a high-voltage busbar arc flash protection device, including a main body with terminals mounted on its side wall, an end cover, a mounting base, an installation mechanism, and an arc flash sensor. The end cover is fixedly mounted on the main body and has a display screen and control buttons. The mounting base is located on one side of the main body and has multiple fixing bolts running through it. The installation mechanism is located between the mounting base and the main body for fixing the main body. The arc flash sensor is mounted on the main body. The main body contains a controller and an arc flash protection main controller. This technical solution addresses the problem of low installation and disassembly efficiency in existing arc flash protection devices.
