1. The product has the signal uploading function, i.e. after the fuse is blown, the action signal of fuse may be directly transmitted to the engine room, facilitating the comprehensive control of wind field and preventing the phase-deficient operation of transformer;
2. The metal parts and body on the outer tube of fuse (fiber wound coil) shall be sealed with the thread and sealing ring, completely solving the leakage of oil due to the different hot and cold factors of metal and non-metal materials.
3. With the full range protection, the fault current between the rated current and maximum breaking current may be protected to provide the transformer with the safe and reliable full range protection.
