Description

Description:

High voltage current limiting fuse WKNHO-12-250A is suitable for AC 50HZ, rated voltage 3.6-12KV systems, and can also be used in conjunction with other electrical appliances (such as switches, contactors, etc.) as overload or short-circuit protection for electrical equipment such as motors, transformers, and capacitors, etc. Protect.

High voltage current limiting fuse WKNHO-12-250A is required to fuse very quickly when the fault current flows, so as to achieve the purpose of limiting the short-circuit current. Therefore, there are some high-speed fusing metals in the middle of the fuse, and its resistance is relatively large, and the measured resistance of the fuse is also large. Non-current-limiting fuses do not have this requirement. The fuses in a switch cabinet should be the same, and two different fuses should not appear. High-voltage fuses have the following differences from high-voltage current-limiting fuses:

High-voltage fuses are the simplest protective devices. They are used to protect electrical equipment from overload and short-circuit current damage; The fuse should be selected series; the fuse we often say is the fuse class. It is mainly used for overload and short- circuit protection of high-voltage transmission lines, voltage transformers, voltage transformers and other electrical equipment.
