126kV vacuum interrupting environmentally friendly GIS is independently developed by TBEA Shangkai Company. The product adopts three-phase common box design and includes main components such as circuit breaker, three-position isolating grounding switch, fast grounding switch, current transformer, voltage transformer, busbar, bushing, and cable terminal. The circuit breaker adopts vertical layout, the operating mechanism is placed above the circuit breaker body, and the circuit breaker body is equipped with three-phase vacuum interrupters as arc extinguishing units, filled with clean air as the insulating medium. The remaining modules are filled with clean air as the insulating medium and arc extinguishing medium for small current breaking, truly achieving "zero carbon" and "zero fluorine" switchgear, without the need for special gas recovery and treatment devices, and lower operation and maintenance costs throughout the life cycle.
Product Features
- Adopts large-capacity vacuum interrupter, with the ability to break large currents while enhancing current-carrying capacity in clean air medium;
- Friendly to the environment and operators, no toxic by-products after breaking, truly achieving GWP=0;
- The ultra-low liquefaction temperature of clean air can be applied to low-temperature conditions and can be used in ambient temperatures of -55℃ without heating devices.
