東軟載波(300183.SZ)取得一項發明專利 涉一種保護電路
格隆匯 04-21 18:25

格隆匯4月21日丨東軟載波(300183.SZ)公佈,公司於近日取得一項發明專利,並取得了國家知識產權局頒發的相關專利證書,涉一種保護電路。

該發明公開了一種保護電路,屬於電路技術領域。該保護電路包括欠壓保護電路,耐高壓保護電路,過流檢測和過流關斷保護電路;所述過流檢測電路與外部輸入電源IN12V相連;所述耐高壓保護電路與過流檢測電路相連;所述過流關斷保護電路分別與過流檢測電路和欠壓保護電路相連。其同時有過壓保護和欠壓保護電路,當低壓電力線電壓過高,防止後級電路過壓損壞;當電壓過低時,使能關閉發送電路,防止設備異常導致電路損壞,從而更加適於實用。

該專利技術可以使載波通信模塊適應各類現場已運行的電能表(電源方式、供電電壓及帶載能力不同,且部分表型供電電壓會隨電網電壓波動),增加保護電路,在電網電壓過高時保障載波模塊電源穩定性,在電網電壓過低時自動降低載波輸出功率,減少載波模塊對電能表電源的消耗,同時提高了載波通信對於電力線負載變化適應性。

該發明專利技術目前已應用於公司智能電網解決方案和產品,不會對公司目前經營產生重大影響。專利的取得有利於公司充分發揮公司技術在智能電網解決方案的主導作用和知識產權優勢,完善了公司技術和產品在智能電網的產品線,形成持續創新機制,提升公司的核心競爭力,為公司拓展智能電網市場起到積極作用。
