An 11 kV dropout fuse is a protective device used in electrical power distribution systems operating at 11,000 volts (11 kV). Here's an overview of its key features and functions:
Voltage Rating: The fuse is specifically designed to operate at 11 kV, making it suitable for medium-voltage power distribution systems.
Protective Function: The primary function of the dropout fuse is to protect the electrical system from overcurrent conditions, such as short circuits or overloads. It operates by interrupting the flow of current when the current exceeds a predetermined threshold.
Construction: A typical dropout fuse consists of a fuse element enclosed within a protective housing. The fuse element is usually made of a material with a low melting point, such as copper or silver, which melts when subjected to excessive current flow.
Mounting: Dropout fuses are usually mounted on insulating supports or brackets, either indoors or outdoors, depending on the application and environment.
Installation: These fuses are installed in series with the distribution lines or equipment they are intended to protect. They are often installed in conjunction with other protective devices, such as circuit breakers or reclosers, for comprehensive protection.
Operational Principle: The fuse operates based on the principle of thermal protection. When the current exceeds the rated value, the fuse element heats up due to the Joule effect. Eventually, the fuse element melts or "drops out," interrupting the circuit and isolating the faulty section from the rest of the system.
Resetting: Unlike circuit breakers, most dropout fuses are designed for one-time use and must be replaced after they operate. Once the fuse element melts, it must be replaced with a new fuse to restore protection to the system.
Visual Indication: Some dropout fuses are equipped with indicators that show when the fuse has operated, making it easier for maintenance personnel to identify and replace the faulty fuse.
