Description
[technical field]
The utility model relates to the switch of urban electricity supply network ring main unit, specifically is meant a kind of environment-friendly type all insulation single-phase switch module.
[background technology]
In the Medium voltage switch or circuit breaker field, just have only the notion of a no oiling in China, refusal oil switch technology worries that fire works the mischief to personal safety, and the SF6 switch that endangers personal safety equally is widely used in the power supply plan.SF6 gas can produce the gas of harmful health through electrode discharge; Simultaneously, when switch reached useful life, reclaiming was again a link that must take into full account.The existing output in 1 year of SF6 switch of China is hundreds thousand of, and the gas leakage and the problem of scrapping will be serious day by day after moving 10～20 years.Does the problem that faces at present comprise: can use the gas that the technology of present stage can be waste and old with these to reclaim? how to bear the cost recovery of great number? not domestic in earlier stage not predicting in problems such as the recovery of reclaiming SF6 gas, processing.Therefore, should adopt an effective measure and crack this difficult problem.It is contemplated that,, can significantly reduce the discharging of SO2, CO2 if all change all SF6 switches into vacuum switch (in intermediate voltage electric power system, the SF6 switch can replace with vacuum switch or solid insulation switch fully).
But still there are following drawbacks in two kinds of patterns of SF6 gas type on-load switch and vacuum circuit-breaker: 1, use SF6 gas type on-load switch to the environment structure potential hazard, SF6 combines with water, can produce the goods and materials poisonous to human body, atmosphere is produced heavy damage, and gas is difficult to recycle; 2, it is long that vacuum circuit-breaker has the life-span, and structure member is simple, dielectric strength recovers fast, do not have the contamination hazard of SF6 gas to environment, but owing to integrally-built reason, its profile is comparatively huge, and need complicated control and protection loop, overall cost height.3, no matter SF6 gas type on-load switch or its three-phase of vacuum circuit-breaker all are integrated, and can only change the maintenance cost height to whole equipment during single-phase breaking down.
Therefore, angle analysis-by-synthesis based on technical feasibility, energy-conserving and environment-protective, need a kind of advantage that SF6 gas type on-load switch and vacuum circuit-breaker are comprehensively arranged, having that all insulation, volume are little, convenient for installation and maintenance, pressing solidly the body insulation technology in the environmental protection notion, the environment-friendly type be made up of single-phase module is the big trend and direction of whole switch industry.
[utility model content]
