    摘 要:由于環(huán)保氣體絕緣開關(guān)設(shè)備是完全密封的,其散熱工況極差,針對(duì) 12 kV/4 000 A 環(huán)保氣體絕緣開關(guān)設(shè)備研發(fā)中的熱傳遞與散熱問(wèn)題,開發(fā)了一種組裝式斷路器。對(duì)斷路器的內(nèi)部結(jié)構(gòu)設(shè)計(jì)進(jìn)行了優(yōu)化,增大有效的散熱面積,同時(shí)優(yōu)化風(fēng)道與風(fēng)機(jī)布局來(lái)進(jìn)一步擴(kuò)大散熱面積,強(qiáng)化外部熱對(duì)流交換。試驗(yàn)結(jié)果表明,溫升值完全控制在標(biāo)準(zhǔn)要求的范圍內(nèi),開發(fā)的 12 kV/4 000 A 環(huán)保氣體絕緣開關(guān)設(shè)備滿足溫升標(biāo)準(zhǔn),確保了開關(guān)柜運(yùn)行的可靠性。

    Abstract: Due to the fact that environmentally friendly gas insulated switchgear was completely sealed, its heat dissipation conditions were extremely poor. An assembled circuit breaker was designed, which aimed at the problem of heat transfer and heat dissipation in the development of 12 kV/4 000 A environmentally friendly gas insulated switchgear. In this paper, the internal structure design of circuit breaker was optimized, heat dissipation area effectively was increased and air duct and fan layout was optimized, which further expanded the heat dissipation area and strengthened the external heat convection exchange. The test results show that the temperature rise is completely controlled within the standard requirements, and the developed 12 kV/4 000 A environmentally friendly gas insulated switchgear meets the temperature rise standards, ensuring the reliability of the switchgear operation.
    Key words: environmentally friendly gas insulated switchgear; heat transfer; heat dissipation area; heat convection exchange; temperature rise control
