Selection guide and cooperation support
1. Selection criteria
Select the appropriate equipment based on the operating scenario (normal operation/fault operation) and load type (inductive/capacitive/resistive), and provide a detailed selection table in the document (example: inductive load selection under normal operation scenario):
Load type, current range, and equipment adaptation notes
No load transformer ≤ 0.03I, circuit breaker, contactor, switch isolator, recloser with neutral grounding transformer
When the motor is running and the circuit breaker and contactor are started, the current is ≤ 7Ir (cos π≤ 0.3)
Compensation reactor ≤ 2000A, transient recovery voltage rise rate of circuit breaker ≤ 6kV/μ s
2. Siemens cooperation and support
Collaboration Plan: Provide standardized testing systems (compliant with IEC 62271-200), design drawings, technical consulting, production training, and software tools (engineering design/document management) for switchgear manufacturers;
Supporting equipment:
SIMOPRIME: Medium voltage air insulated switchgear, compatible with SION 3AE circuit breakers, 7.2kV-24kV;
SIVACON S8: Low voltage distribution panel, rated current ≤ 7000A, in compliance with IEC 61439-2;
