20A-800A 750V 50Ka High Speed New Energy Electric Vehicle Battery
Fuse
This products are round tube bolted fuses, which have the
characteristics ofsmall size, high breaking capacity, resistance to
current impact, and canwithstand high-strength mechanical vibration
and impact, wide temperaturerange impact, and strong chemicalload,
and are suitable for the road vehicleindustry Application, can be
used for short circuit and backup protection ofelectric vehicle
drive power system, power conversion system, energystorage and
power system, frequency conversion controller, charger, wireand
other vehicle devices and equipment.
Purpose and use
This series of fuses are suitable for lines with rated DC voltage
below 1000V, rated current of 100A-200A and breaking capacity of
20kA. They are widely used in chargers. Comprehensive protection of
charging pile, on-board battery, on-board circuit system and
inverter. At the same time, it has the characteristics of strong
current limiting capacity, large breaking capacity and fast
short-circuit breaking speed. It can withstand temperature shock,
mechanical vibration shock, current shock, chemical load, etc. This
series of products conform to ISO 8820, JASO D622 and GB / T31465
standards.
Normal working conditions
Normal operating conditions of ambient air temperature: - 5 ℃ ~ 40 ℃; allowable operating conditions: - 40 ℃ ~ + 125 ℃;Relative humidity: 5% ~ 95%;Atmospheric pressure: 61.6 kPa ~ 106.2 kPa.
3. Use category
Full range fast fuse(gR)
Structural characteristics
The melting tube of the product is made of high-temperature resistant ceramic material, with high flame-retardant performance and strong hardness.
The melt is sealed in the melting tube with a variable
cross-section melt made of 99.99% pure silver. The melting tube is
filled with chemically treated high-purity quartz sand and
specially treated chemical materials as arc extinguishing medium.
The contact surface is silver plated to ensure reliable electrical
performance, greatly reducing temperature rise and power
consumption; Both ends of the melt are firmly connected with the
contact by spot welding, which greatly enhances the safety and
reliability of breaking short circuit fault current
