Principle and Function of Fuse Cut Out
The high-voltage drop-out fuse consists of three parts: insulating support, dynamic and static contacts, and fuse tube. The static contacts are installed at both ends of the insulating support, and the fuse tube is composed of an inner arc suppression tube and an outer phenolic paper tube or epoxy glass fiber cloth tube.
Drop-out fuses are suitable for power systems with a frequency of 50/60Hz and a rated voltage of 35KV and below, and are installed on the high-voltage side of distribution transformers or on the main lines of distribution. The main function is where the protection performance is not high, it can be used in conjunction with the isolating switch to replace the automatic air switch; it can also be used in conjunction with the load switch to replace the expensive circuit breaker. It also has short circuit protection, overload and isolation circuits.
Electric Fuse Switch General
1.Made of high quality material, it has long service life. The fusant is made of pure copper strip. The fusion tube is made of high strength china. The extinguishing medium is made of pure quartz sand.
2.Easy installation and maintenance. The terminal of fusant contacting with the end-plate (or the connecting plate) use the technology of spot welding.
3.Safe indication. The fuse with the indicator can be show the fusing when the indicator pop-up.
4.Durable and reliable
