HV disconnector with earthing switch

Outdoor three-pole disconnector on four tubular columns and cross beams. Centre-break: two rotating post insulators per phase on bearings, carrying contact arms that meet in the middle (male and finger contacts) and swing 90° to the same side as open goes to 1. Pantograph: a support insulator and a rotating operating insulator, with scissor arms folding as it opens. Each phase has a hinged earthing blade that rises to the terminal when earthed and the main contacts are open. Motor operating mechanism with drive shaft and interphase coupling rods; manual earthing-switch mechanism.

Installation

Copies onshore/disconnector.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 { Disconnector } from './components/deck-twin/onshore/disconnector'

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

Props

P&ID

Single-line: a switch blade with a short bar across the fixed contact (disconnector), usually next to an earthing switch drawn as a second blade going to the earth symbol (three shortening lines).

tag QBtag QCIEC 60617 (single-line diagram); IEC 62271-102

Bar on the contact = disconnector (isolator, no load breaking); × = circuit breaker. Some drawings tag disconnectors DS. ANSI device numbers are 89 for the disconnector and 57 for the earthing switch.

For agents

Machine-readable entry with props, ranges, defaults and ports:

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

Add the Deck Twin "HV disconnector with earthing switch" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add disconnector` (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 disconnector` for its props, ranges and ports. Render <Disconnector /> 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.
