Brief analysis of the advantages of drop-out fuse products

Drop-out fuses are a common short-circuit protection switch. They are economical, easy to operate, and highly adaptable to outdoor environments. They are widely used in 10kV distribution line branches and distribution transformers to protect the primary side and perform equipment switching operations.

Fuse can be said to be a relatively common device in the circuit. As a protective device, this device is actually a relatively typical device. As one of the more famous drop-out fuses, it mainly uses certain connecting components to connect with the fuse. When the current in the circuit is overloaded, this device generates a thermal effect by itself to disconnect the fuse inside the fuse, thereby disconnecting the circuit and playing a role in protecting the circuit. In this process, since the drop-out fuse is generally installed on the branch line of the 10kV distribution line, the scope of power outage can be reduced. Because it has an obvious disconnection point and has the function of isolating the current, it acts a bit like a switch, so it is also a relatively distinctive protection device.

Its practicality is also one of the higher ones among fuses, but it also has certain defects. The station transformer drop-out fuse is exposed to the outdoors for a long time and will break due to severe corrosion and aging. This is its advantage and disadvantage.
