Introduction
Analysis of the core content of the standard
This standard applies to the design and manufacture of high-voltage shore power boxes (cabinets), with a system nominal voltage range of 1-15kV, a rated current of ≤4000A, and a frequency of 50/60Hz. It mainly regulates key technical requirements such as equipment classification, safety protection, and electromagnetic compatibility.
Comparison of key technical requirements
| Technical indicators | Fixed type | Removable type |
|---|---|---|
| Protection grade | IP42(indoor)/IP56(outdoor) | Same requirements |
| Electrical clearance | According to 7.2kV system≥90mm | |
| Five-protection interlocking | Mechanical interlocking as the main one | Electromechanical double interlocking |
Typical application cases
The cruise ship shore power system adopts HSPB-12/1250/31.5-60-C equipment to meet the 11kV/60Hz power supply requirements, and is equipped with 25kA short-circuit withstand capability and differential protection. Efficient power supply is achieved through the combined installation in Appendix A.3.
Standard evolution background
With the update of the IEC/IEEE 80005-1 international standard, this standard adds electromagnetic compatibility test (Table 9) and internal arc protection (5.3.2.5) requirements, which strengthens the compatibility with ship-shore systems.
Implementation suggestions
- Refer to Table 2 to match the rated parameters according to the ship type when selecting
- The installation method should be selected in combination with the cable management system location (Appendix A)
- Perform 6.12 withstand voltage test and 6.22 electromagnetic compatibility test regularly
