Product Application of DC fuse

This series of products are pin fuse, with small size, high breaking ability characteristics. Suitable for wide temperature range, can tolerate high strength mechanical vibration and impact, wide temperature impact and a reinforcement learning load, suitable for road vehicles industry application, can be used as short circuit and backup protection for electric vehicle driving power system, power conversion system, energy storage and power battery, energy storage capacitor, frequency conversion controller, charger, wire and other vehicle devices and equipment.

Product Structure

The melting tube of the DC fuse is made of high -temperature resistance ceramic material, which has high fire performance and solid hardness.
Seal the melt in the melting pipe and make 99.99 % sterling silver into a variable cross -section melt. The melting tube fills the chemical treatment of high -purity quartz sand and specially treated chemical materials as an arc to extinguish the agglomeration.

Working conditions

Normal working conditions

a) The fuse is installed separately in natural air without ventilation. Except for the connecting wires, there are no other heat-generating parts or heat-dissipating parts within 1m.

b) The fuse connection terminal should ensure stable and reliable electrical contact. The contact resistance should not significantly affect the operation of the fuse.

c) The fuse can be installed vertically, horizontally or obliquely. If you rely on spring pressure to ensure the electrical connection of the fuse, you should choose a suitable location during installation to avoid the adverse effects of gravity and vibration on the electrical connection.
