The Role Of Drop-out Fuses In Circuit Protection Should Not Be Underestimated.
In power distribution networks, the 11kv drop out fuse manufacturer fuse is widely used on the high-voltage side of pole-mounted transformers or branch lines. This device has a simple structure, consisting of an insulating support and a fuse tube. The stationary contacts are fixed to both ends of the support, and the fuse tube connects the moving contact to the current-conducting part.
During operation, when an abnormal increase in current (such as a short circuit or overload) causes the fuse to melt, the arc within the fuse is quickly extinguished by the arc-extinguishing mechanism inside the fuse tube. After losing tension, the fuse tube "falls" under the action of gravity and a spring, cutting off the circuit and creating a clear break point. Thus, the faulty section can be quickly isolated.
The 33kv drop out fuse fuse is suitable for 10kV distribution lines and the primary side of transformers. This deployment method is particularly important for branch lines or terminal lines. In many cases, areas difficult to cover with relay protection can have their protection range extended by the 33kv fuse fuse.
The cover drop out fuse fuse requires relatively less investment and is easy to install outdoors. Its insulating support and weather-resistant structure are ideal for overhead lines and outdoor environments. This characteristic makes it the most common short-circuit protection switch in rural power distribution networks or branch lines.
