Fuses

0470002.DRSNP(DR Sun Power) is a kind of new special high voltage fuse, which is developed by Beijing DR Sun Power S&T Co., Ltd. It is a low voltage and high current distributed fuse with unique structure and principle. It can be widely used in important circuits of high voltage AC, DC, high voltage power and other circuits, and can provide safe and reliable protection for power system.

The main application field of 0470002.DRSNP includes solar energy application, wind power application, electric locomotive, high voltage DC, electric power and other high voltage power fields. It can provide reliable protection for the system.

0470002.DRSNP has the advantages of small size, light weight, no clearing, no arc extinction, stable performance and current uniform distribution. It is the best choice for protecting power system and other important power supplies, which can reduce the secondary power failure caused by over-current and reduce the maintenance cost of power failure.

The working principle of 0470002.DRSNP is similar to traditional fuse, but it is more reliable. It consists of a set of flame arrester, a set of metal mesh and two sets of current switch. The circuit of the fuse is a parallel circuit which has the function of overcurrent protection. When the current is too large, the current switch is turned on to reduce the current, and the flame arrester can effectively extinguish the arc.

Compared with traditional fuse, the 0470002.DRSNP has better performance. Its current uniform distribution can ensure that the maximum current of the fuse circuit will not exceed its rated current, and its arc extinguishing performance is better than that of traditional fuse. It can effectively reduce the power system failure rate.

In conclusion, 0470002.DRSNP is a very convenient, reliable and safe fuse with wide application. It can provide reliable protection and reduce system failure rate, which has significant advantages compared with traditional fuse. It is the best choice for protecting power system and other important power system.
