HV circuit breaker (live tank SF6)

Outdoor live-tank SF6 circuit breaker: three poles on a common base frame carried by two tubular columns on piers. Each pole has a support insulator, a cast mechanism head with the lower terminal pad, an interrupter insulator and a top flange with the upper terminal. At 420 kV the head is a T with two horizontal interrupters, grading capacitors and corona rings. SF6 density monitors, gas piping, interphase linkage, and a spring operating-mechanism cubicle under the frame. Insulator heights and phase spacing follow the rated voltage.

Installation

Copies onshore/hv-circuit-breaker.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 { HvCircuitBreaker } from './components/deck-twin/onshore/hv-circuit-breaker'

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

Props

P&ID

Single-line: a switch blade (a line at an angle) with a small × on the fixed contact, in the feeder between busbar and line or transformer; often drawn inside a bay with disconnectors on either side.

tag CBtag QAIEC 60617 (single-line diagram); IEC 62271-100

IEC symbols: × on the contact = circuit breaker; a bar across the contact = disconnector; a blade to the earth symbol = earthing switch. ANSI drawings use a square box with device number 52. QA / QB / QC are IEC 81346-2 class letters for breaker, disconnector and earthing switch.

Or fetch /r/hv-circuit-breaker.json, or copy a ready-made instruction:

Add the Deck Twin "HV circuit breaker (live tank SF6)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add hv-circuit-breaker` (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 hv-circuit-breaker` for its props, ranges and ports. Render <HvCircuitBreaker /> 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.
