Second, the high voltage load switch model meaning example
For example, FN2- 10R/400 type refers to: load switch, indoor type, design serial number 2, rated voltage 10KV, with fuse (installed at the top of the switch), rated voltage 400 A.
Third, the classification:
1)? According to the installation position, it is divided into indoor type and outdoor type;
2)? According to the arc extinguishing methods, it can be divided into gas generation type, compressed air type, compressed air type, oil immersion type, vacuum type and SF6 type.
3)? According to the fusion or not, it can be divided into fusion and non-fusion.
Although the high-voltage load switch has the advantages of high breaking capacity, safety, reliability and long service life, these are also based on the harsh use environment. For example, it can only be used in places where there is no conductive dust, corrosive gas and water vapor, and there is a danger of fire and explosion and frequent violent vibration. Otherwise, it will not only fail to ensure proper and reasonable results, but also lead to a series of failures and losses, which will seriously lead to additional disasters and troubles. In addition, consumers also need to refer to the manufacturers of high-voltage load switches to learn.
