Sf6 Gis Gas Insulated Switchgear

sf6 gis gas insulated switchgear uses SF6 gas as the insulating medium to insulate primary equipment other than transformer in a substation, such as circuit breaker, isolation switch, ground switch, voltage transformer, current transformer, lightning arrester, bus bar, cable terminal, inlet and outlet bushing, etc. Optimized design organically combined into a whole. This kind of equipment has been widely used in power system because of its high integration and closure.

Zi Kai sf6 gis gas insulated switchgear Feature And Application

Feature

Small footprint: Due to the fully enclosed structure and highly integrated design, SF6 GIS equipment can significantly reduce footprint and reduce land costs.

High reliability: the live part is all sealed in the inert SF6 gas, which is not affected by the external environment, greatly improving the reliability of the equipment.

Good safety: the live part is sealed in the grounded metal housing, there is no danger of electric shock; At the same time, SF6 gas is a non-burning gas and has no fire risk.

Easy maintenance: Due to its reasonable structure layout and advanced arc extinguishing system, it greatly improves the service life and maintenance cycle of the product and reduces the maintenance workload.

Small electromagnetic interference: the charged part is closed with a metal shell, shielding electromagnetic and static electricity, low noise, strong anti-radio interference ability.

Application

Substation: As one of the main equipment of substation, gis gas insulated switchgear can significantly reduce the footprint of substation and improve the reliability and operation efficiency of equipment.

Urban power grid: In the process of urban power grid transformation and upgrading, gis gas insulated switchgear equipment has become one of the preferred solutions because of its small footprint and easy maintenance.

Industrial field: In industrial production environments, gis gas insulated switchgear equipment can ensure the stability and reliability of power supply, and meet the demand for high-load and high-reliability power.
