The advantages of High Voltage High Current Switches
High voltage refers to the power system which deals with voltage above 36KV. Higher voltage level results in higher arching during switching operations. The main component of high voltage high current switch gear is the high voltage circuit breaker, so it is essential for the high voltage circuit breaker to possess special features for safe and reliable operations. Cases of faulty tripping and switching operation of high voltage circuits are very rare. The last fifteen years has witnessed a radical change in the high voltage circuit breaker technology.
In comparison to linear switching supplies, not only is the high voltage switching direct current power supplies more advantageous, but its increased efficiency, dependability and a state of art schematic diagram, have resulted in these high voltage units to be lighter in their overall weight as well. The light weight is due to the fact that these devices do not come equipped with the traditional, heavy and low frequency transformers. There is also lower generation of variable heat as these high voltage, high current switches are more efficient.
The compact design and the process of easy installation of these switches make this an ideal replacement of power fuses to achieve three phase protection. High voltage, high current switches have been developed to overcome some of the limitations of fusing for substation power transformers. They also provide protection for transient overloads and excess voltages at a competitive cost. In addition to the above benefits, these high voltage, high current switches also provide protection from power transformer faults based on differential, sudden pressure and over current relay schemes. It also provides protection from critical operating constraints such as low oil level, high oil level or winding temperature and pressure relief device operations. The straightforward mechanical design ensures and guarantees long life and repeatable operation.
