Product Description

 

General

SF6 live tank Circuit Breaker outdoor sf6 circuit breaker 126kv using SF6 gas as arc extinguishing and insulating medium, using the most advanced self-energy arc extinguishing technology in the world, equipped with a new type of spring operating mechanism, it has the characteristics of long electrical life, low operating power, low noise and high reliability.

Service environment

  • Ambient temperature :-40 ° C ~+40° C;

  • Altitude: no more than 3000m;

  • Wind speed: not more than 34m/s;

  • Daily temperature difference: not more than 25°C;

  • Sunshine intensity: not more than 0.1w/cm2;

  • Monthly average relative humidity: not more than 90%;

  • Seismic acceleration: horizontal is not more than 0.2g, vertical is not more than 0.1g;

  • Ice thickness: no more than 10mm;

  • Air pollution degree: not more than GB5582 level IV;

  • Installation occasion: outdoor.

Key Feature

  • Circuit breaker adopts three-phase porcelain bottle pillar structure, outdoor design, three-phase with an SRCT36-C spring operating mechanism, centered arrangement, three-phase continuous movement, so the appearance is novel and exquisite.

  • The circuit breaker uses SF6 gas as insulation and arc extinguishing medium, and the three SF6 gas poles of the circuit breaker should be connected during operation, and the pressure and density of the circuit breaker should be monitored by a pointer density relay.

  • The principle of self-energy arc extinguishing is adopted, and the optimal design is carried out in the circuit breaker motion system, so the mechanical efficiency is effectively improved.
