Main functions of high-voltage fuses

High voltage fuse is a device used to protect electrical equipment and lines in the power system from overcurrent or short circuit faults. Its main function is to quickly cut off the fault current in the event of a line fault (such as current overload or circuit short circuit, etc.), thereby avoiding or reducing damage to equipment and lines, as well as harm to personnel and the environment. In addition, high-voltage fuses can also be used to switch no-load lines or transformers, and as isolating switches.
After understanding the main functions of high-voltage fuses, let's take a look at where they are mainly used.
The places where high-voltage fuses are used mainly include substations, power plants, industrial enterprises, and various public facilities.
High voltage fuses are mainly used as protective elements for transformers, buses, and other equipment in substations to prevent the expansion of faults and causing equipment damage or casualties.
High voltage fuses are used in power plants as protective elements for generators, excitation systems, steam turbines, and other equipment to prevent equipment damage or shutdown caused by overloads or short circuits.
In industrial enterprises, high-voltage fuses can also be used as protective elements for high-voltage motors, frequency converters, welding machines, and other equipment to prevent overloads or short circuits from causing fires or explosions.

For equipment such as public facilities, high-voltage fuses can be used as protective elements for public facilities such as rail transit, urban water supply, and hospitals to ensure public safety and service quality.
