XRNP 6KV 12KV 40.5KV 50KA High voltage current limiting fuses for protection of voltage transformers
Product Description:
High voltage current limiting fuses are used for voltage transformer protection. Fuses are the simplest protective devices used to protect electrical equipment from overload and short-circuit currents; Choose different types of high-voltage fuses according to installation conditions and purposes, such as outdoor drop type and indoor type. For some special equipment high-voltage fuses, special series should be selected; The fuse we often refer to is a fuse type.
This product is used for overload and short circuit protection of voltage transformers in indoor AC 50Hz, rated voltage 3.6-40.5kV systems.
Model Description:
Technical parameters and Installation size:
Product Structural features:
1. There is a range between the minimum breaking current and the minimum melting current of ordinary current limiting fuses. In this range, it cannot effectively break the current and may even cause the fuse to explode, and the area will further widen as the fuse is reduced in capacity. Due to this deficiency, ordinary current limiting fuses must rely on switches or other combination devices to break the current in this section. However, for the full range protection fuse of the F series, there is no need to combine it with other electrical appliances due to the absence of this cell.
2. The protection feature of the F series full range protection fuse is that it has a greater ability to withstand transformer surge currents and is closer to the overload withstand curve of the transformer. The safety method and selec1. There is a range between the minimum breaking current and the minimum melting current of ordinary current limiting fuses.
