Expulsion fuse cutout is the most commonly used short-circuit protection switch for 11-38kV distribution line branch lines and distribution transformers. It is widely used in 11-38kV distribution lines and the primary side of the distribution transformer is used for protection and equipment switching and switching operations. Throughout this process, drop fuses can be reduced to very small outages because they are usually installed on 10-38 kv overhead line branch networks. It has obvious breakpoint, and has the function of protecting current. The effect is similar to that of a power switch, so it is a more distinctive protector
