This manual explains the construction, principle and operation of the SHK SHK‑FUR high‑voltage current‑limiting fuse assembly. It details the fast‑acting fuse (FU) and nonlinear resistor (FR) combination that can interrupt fault currents within 1‑2 ms, limiting over‑voltage and protecting downstream equipment.
The document also covers typical applications such as hydro‑power plant auxiliary branches and excitation transformer high‑voltage sides, provides ordering information, installation, commissioning, and maintenance procedures, and lists the technical specifications and model options available. This manual is written in Chinese.
| Breaking current | 160 kA |
|---|---|
| Operation time | 1‑2 ms |
The device interrupts the fault within 1‑2 ms, cutting off the current rapidly.
It can break fault currents up to 160 kA.
It is used for hydro‑power plant auxiliary branches and for protecting excitation transformers on the high‑voltage side.
