电气间隙与爬电距离计算器

Design-condition checklist

请与安全工程师依据适用标准评估电气间隙和爬电距离的设计条件。距离数值暂不可用。

电气间隙与爬电距离 — 设计条件检查清单(数值计算器暂不可用)

电气间隙和爬电距离的数值结果暂不可用。先前的模型缺少经核实的 IEC 标准原文和完整的设计条件模型,因此已停用,等待审查。

Prepare these design conditions for review by a qualified safety engineer:

  • 工作电压与波形
  • 冲击电压与瞬态条件
  • 污染等级与环境
  • 过电压类别
  • 绝缘类型
  • 材料组别及层压板供应商提供的、经核实的 CTI(不得根据 FR-4 推断)
  • 运行海拔高度
  • 适用的产品标准

重要安全提示

Consult the full applicable safety and product standards and have the design reviewed by a qualified safety engineer. This checklist does not determine required distances or establish compliance.

电气间隙与爬电距离常见问题

Why are numeric distances unavailable?

电气间隙和爬电距离的数值结果暂不可用。先前的模型缺少经核实的 IEC 标准原文和完整的设计条件模型,因此已停用,等待审查。

Can FR-4 be assigned one material group?

No. Obtain the actual laminate CTI and material classification from the supplier and review it against the applicable standard.

Who should determine the required distances?

A qualified safety engineer should assess all design conditions against the applicable standards.
