800vac Solar Photovoltaic Power Generation System Solution-JAC Electric
As users have lower and lower cost requirements for solar photovoltaic power generation systems, JAC Electric has designed a solar photovoltaic module inverter with a DC side voltage of 1500VDC from the comprehensive consideration of safety, reliability, economy and related equipment. , The inverter AC side voltage is 800VAC, the inverter transmission cable is connected to the low-voltage side GLBM3HU 800VAC circuit breaker of the ZGS booster box-type substation, and the low-voltage power distribution panel of the ZGS booster box-type substation is composed of GLBM3HU 800VAC molded case circuit breakers and GLBW1 800VAC Frame circuit breaker, 0.8KV step-up transformer and high-voltage cabinet (the high-voltage side voltage is 10KV or 35KV)
The advantage of this scheme designed by JAC Electric is to save the cost to the greatest extent. It adopts string photovoltaic inverters (when one of the inverters needs to be replaced or repaired, it does not require large-scale power outages and repairs, only the ZGS booster box-type substation is needed. The corresponding inverter GLBM3HU 800VAC molded case circuit breaker can be repaired after disconnection, without affecting the operation of other inverters)
