Product Description

High voltage current limiting fuse, also known as high breaking capacity fuse, is one of the important protection equipment in power system. Their main
Features to include:
1, the ability to break the short circuit current is strong: can quickly cut off the current before the short circuit current reaches the maximum value, thus limiting the influence of the fault.
2, significant current limiting effect: by cutting off the current before the short circuit current reaches the maximum, effectively reduce the impact of short circuit current on the power system.
The structure of high voltage current limiting fuses usually includes:
Ceramic housing: provides mechanical protection and insulation properties.
Melt: Generally made of sterling silver, the melt can be filament or ribbon, depending on the rated current. The ribbon melt will have equal distance notches, and the shape and spacing of these notches have an important effect on the performance of the fuse.
Quartz sand: acts as an arc extinguishing medium to help extinguish the arc during the fusing process.
High voltage current limiting fuses work by using the melting and vaporization of the melt to quickly cut off the circuit, thereby protecting critical power equipment such as generators and transformers from short-circuit current damage. However, this fast cut-off process may produce high temperature, high voltage and overvoltage, which may cause equipment failure or the misoperation of the relay protection device.
High voltage current limiting fuses have been used for more than a century, their structure is simple, low cost, and they have good overload and short circuit protection. With the introduction of new materials, new processes and new structures, such as the combination of vacuum fuse and arrester or load switch, its protection performance has been further improved, making it widely used at home and abroad
