FAQ：
Q1: How to ensure the safety of 1000V HVDC system?
A: Triple protection design:
A fast fuse is configured on the DC side to cut off the short circuit within 15ms
Positive and negative double insulation monitoring, leakage current > 30mA automatic power off
The grounding resistance of the cabinet is less than 0.1Ω and passes the IEC63056 voltage test
Q2: Is the energy consumption of the liquid cooling system too high?
A: Adopt variable frequency pump + zone temperature control strategy:
Standby power consumption < 200W, full load power consumption < 1.2kW
Compared with the traditional scheme, energy saving 40%, comprehensive energy efficiency > 88%
Q3: What is the effect of 2000 m high altitude on heat dissipation?
A: Performance is ensured through three optimizations:
The liquid cooling pipe pressure is increased to 1.5 times the standard value
The radiator area is increased by 20% to compensate for the decrease in air density
The fan speed is adjusted intelligently to maintain the heat transfer efficiency
Q4: How to achieve rapid expansion?
A: Support "stacking between cabinets" technology:
Four SE418L-215Ks can be connected in parallel up to 860kW/1.672MWh
Parallel circulation < 1%, no additional balancing controller required
Q5: What operations are required for routine maintenance?
A: Intelligent maintenance-free design:
The internal resistance detection is performed automatically every 6 months, and the abnormal cell is marked automatically
The liquid cooling pipe is equipped with self-cleaning function, and the coolant is not replaced for 5 years
The fire prevention system self-checks every month, and the results are sent to the operation and maintenance platform
