Substation strain gantry

Pair of substation strain gantries span apart: square lattice columns on piers, box lattice girders, earth-wire peaks with shield wires, anti-climb guards and earth bonds. Each phase of each bay has cap-and-pin glass strain strings (disc count by voltage) and a stranded conductor with about 3 % sag, twin-bundled at 420 kV. Bay width, column height and phase spacing scale with kv.

Installation

Copies onshore/busbar-gantry.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { BusbarGantry } from './components/deck-twin/onshore/busbar-gantry'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <BusbarGantry />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

Single-line: a thick horizontal line (busbar) with bay connections dropping from it at dots; on substation layouts and elevations the gantry is a pair of lattice columns with a girder carrying strain insulator strings and the bus conductors.

A thick line with feeders = busbar. Double-busbar stations show two parallel thick lines with a coupler bay between them.

Or fetch /r/busbar-gantry.json, or copy a ready-made instruction:

Add the Deck Twin "Substation strain gantry" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add busbar-gantry` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info busbar-gantry` for its props, ranges and ports. Render <BusbarGantry /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
