Large Current Solid State Switch 10KV~35KV (power electronic breaker)

Brief introduction of large current solid state switch 10KV~35KV

Developed with international leading technology, our solid state switch 10KV~35KV has been a new breakthrough in large current control.

Due to restrictions from physical structure of traditional circuit breaker, it is difficult to increase the switching capacity of the circuit breaker by a large margin. Besides, when moving and fixed contacts break, the arc between them lengthens the turn-off time, which fails to meet the demand for real time, reliable and flexible control of modern power system.

Rongxin solid state switch 10KV~35KV is developed by completely new principle and technology. It has the merits of resistance to high voltage, large current, high surge- resistant capability, large turn-off current and short turn-off time, etc. With stable performance and long life time, our large current solid state switch 10KV~35KV is widely used in modern power system so as to achieve quick, accurate and flexible control of the power system. In addition, it solves the technical difficulty of cutting large current within short time by breaking any short-circuit current that is above 60kA within 10-20ms. Therefore, Rongxin large current solid state switch 10KV~35KV emerges as one of the ideal high power switching devices, filling the blank in the industry.

Rongxin solid state switch 10KV~35KV is widely used as the substitute for imported current switches, and helps to create more value for enterprises.

Rongxin large current solid state switch 10KV~35KV has wide application in distribution circuit of 10KV~35KV. It is extensively used in place of mechanical circuit breaker in order to enhance automatic level of power grid and ensure safety of the power system. The large current solid state switch 10KV~35KV can also be applied in independent power system, such as ships and offshore drilling platforms, factories and mines. As it improves quality of power system, maintains equipment safety and ensures energy efficiency, it is largely adopted instead of imported products by electrical enterprises and power consumers to reduce their cost.

Technical features

b. With no arcing during the switching process
c. Integrated design of relaying protection and the switch (no need of original relaying protection)
d. Single-phase operating mode
e. Telemonitoring and remote control
f. No extra cooling device
g. Maintenance free

Performance index
Rated voltage/current: 10kV－35kV/1000A－3000A
Voltage drop of steady- state operation approximately 0 ( <0.1% )
Turn-off current:  < 200kA (Any short-circuit current over 60kA can be switched in one cycle)
Turn-off time:  10-20ms
Recovery time:  Approximately 0, and thus the large current solid state switch 10KV~35KV is suitable for power system with high-speed reclosure and multiple faults.
