Power Cad Drafter

该 Skill 从用户提供的勘测数据、手绘草图或设计任务书出发，按公司电力施工图设计规范推断负荷、变压器、主接线、接地等设计参数，调用脚本生成单线图、平面布置图、接地平面图与电缆走向图四张 DXF 图纸，再用规则审计引擎对照规范条款输出 Markdown 审计报告，并打包图纸、参数、报告与设备清单。

Auto-generate electrical CAD drawings from survey data and auto-audit against power codes

Power CAD Drafter

Auto-generate DXF construction drawings for 10kV and below power distribution projects, and auto-audit against the company design code and national standards.

Trigger

  • User provides survey data, hand-drawn sketches, or design task brief
  • User requests electrical single-line diagrams, layout plans, or system diagrams
  • User requests drawing review or verification

Prerequisites

python3 -m pip install ezdxf pyyaml

Company code must exist: workspace/电力行业施工图设计规范V1.0.md

Workflow

1. Parse Input Data

Extract structured survey data from user input or parse hand-drawn sketches via vision.

Recommended input format (YAML/JSON):

project:
  name: "XX小区配电工程"
  type: "residential"
survey:
  building_floors: 18
  units_per_floor: 6
  total_area_sqm: 25000
  substation_dimensions: [8.5, 6.2]

2. Design Parameter Inference

Infer design parameters per the company code:

Item Input Output Rule
Load calculation Area, units, load density Demand factor method
Transformer Load, location Dry/oil, D,yn11, standard capacity
Main wiring Load grade, transformer count Single bus / sectionalized
Grounding Substation location TN-S (indoor), TN-C-S (outdoor)
Cable Transformer capacity, routing Ampacity + thermal + voltage drop
Room layout Equipment count, dimensions Aisle width, fire rating, noise

3. Generate DXF Drawings

Run scripts/dxf_generator.py to produce:

Drawing Suffix Content
Single-line diagram _single_line.dxf 10kV and 0.4kV primary system
Layout plan _layout.dxf Equipment positioning, dimensions, aisles
Grounding plan _grounding.dxf Grounding electrodes, equipotential bonding
Cable routing _cable.dxf Trench/bridge paths, cable labels

4. Auto-Audit

Run scripts/audit_engine.py to check against the code and produce a Markdown report.

Core checklist:

  • Load grade matches power supply configuration
  • Transformer capacity ≤ limits (dry ≤1250kVA public, oil ≤630kVA public)
  • Wiring group D,yn11
  • HV switchgear IP ≥ IP4X, five-prevention interlock
  • LV breaker breaking capacity ≥ short-circuit current
  • TN-S grounding mandatory for indoor substations
  • Substation roof fire rating ≥ grade 2
  • Aisle width ≥ 1.5m (fixed) / 1.8m (drawer)
  • Bare conductor height ≥ 2.5m
  • Cable sections ≥ minimums (service ≥10mm² copper, main ≥150mm²)
  • Grounding resistance ≤ 4Ω (≥100kVA transformer)
  • Meter height 0.8–1.8m
  • Reactive compensation 20%–40% of transformer capacity

Report format:

| Category | Item | Result | Design | Required | Clause | Remark |
|----------|------|--------|--------|----------|--------|--------|
