SF6 End-of-life Vacuum CHINT

SF6 End-of-life Vacuum. Sulfur hexafluoride (SF6) is one of the most stable gaseous chemical compounds due to its inertness (Its inertia is comparable with nitrogen (N2) gas) and incombustible nature. It has been more than 6 decades since SF6 is being used in electrical equipment. In fact, Switchgear amounts to 90% of the electronic equipment that uses SF6.

As SF6 is an insulation gas with excellent electrical characteristics, it is possible to distribute and transmit energy with highest electrical safety. If pressure rises inside a compartment, as a result of an internal fault or lightning, the monitor detects this fast-rising pressure and instantly communicated with the control and protection

The fluoroketone-based SF6 alternative gas mixture is a chemical compound developed for switchgear applications by ABB in collaboration with 3M. It has a dielectric performance similar to SF6 when utilized in indoor applications, but with very low Global Warming Potential (GWP)*. Get Price

This solution presents the following advantages: fully environmentally friendly, safe for people, easy to operate, high expecting life and same footprint as current SF6

SF6 gas can be found for example in switchgears and circuit breakers of power transmissions and distribution network facilities. Gas switchgear draining and SF6 gas recycling At the end of the life cycle of the gas switchgear, proper recycling must be done carefully to prevent the gas from entering the atmosphere due to

2019-4-18quenching media including SF6, are normally installed inside a metal enclosure (traditional metal-enclosed switchgear).Another design is the SF6 insulated metal-enclosed switchgear, where the SF6 gas provide the main insulation of the equipment. Vacuum or SF6 interrupters can be used. A particular case,

2020-11-30In SF6 circuit-breakers, contact resistance increases progressively during life. Vacuum interrupters are built from materials that can be recovered and recycled at the end of life. They do not contain greenhouse gases, nor do they present potential health hazards due to the products of decomposition.

2020-7-6End-of-life of GIS is either specified by the end user, reflecting the intended time until replacement of the equipment should be done, or the end-of-life of GIS is specified by the equipment manufacturer stating a minimum lifetime (which can be extended), or by an increased failure rate indicating end-of life. 2-End-of-life of the insulation gas mixture is reached: Non-SF6 gases or gas mixtures may age during lifetime e.g. due to decomposition and reach an end-of-life

SF6 insulated vacuum circuit breaker panel of KEMA ring main unit With the laser cutting and puching machines imported from TRUMPF(Germany), the accuracy of re-location can be 0.02mm; the cutting deviation can be less than 0.05mm, which ensures that before welding the gaps between plates of gas tank are smaller than

Additionally, such regulations also dictate the handling of SF6 gas at switchgear’s end-of-life. Furthermore, a study carried out by Environment Protection Agency demonstrated that the lower and upper bound weighted-average leak rate of HV Circuit Breakers lie between 0.2 to 2.5 percent per year.
