This utility model discloses a
current transformer with a protection device, belonging to the field of
power equipment technology. It includes a
current transformer body, with two ventilation windows on both the front and rear sides of the outer surface of the
current transformer body. Each ventilation window is equipped with a cleaning structure. Each ventilation window is connected to a first inner window and a second inner window located inside the current
transformer body via an air duct. Several shock-absorbing structures are installed at the bottom of the current
transformer body, all mounted on a base plate. Side plates are also provided on the side surfaces of the current
transformer body. This utility model, through the synergistic effect of the ventilation windows, cleaning structures, fan, dust suppression net, shock-absorbing structures, and
moisture-proof pads, achieves heat dissipation, dust prevention, shock absorption, and
moisture protection for the current transformer, effectively improving the reliability and environmental adaptability of the equipment and extending its service life.
