Description

一种节能安全开关
技术领域    本实用新型涉及一种电子产品,尤其是一种电路控制部件。
背景技术    目前,市场上的开关都是人工手动控制的开关,当突然断电时无法将开关关闭,因此当再次通电时开关依然保持闭合,此时突然通电时的不稳定电流很容易烧损电器。如果家里无人时来电,开关闭合后也会使得电器启动而工作,消耗电能并存在安全隐患。另外,现在的开关也无法对漏电隐患提供保护措施,其安全性较低,无法满足人们需求。
发明内容    本实用新型的目的是提供一种在停电后可自动断开并能提供漏电保护的节能安全开关。
本实用新型所述开关由继电器KM、变压器、动合开关SB1、动断开关SB2、继电器开关KM1、继电器开关KM2组成;动合开关SB1与继电器开关KM1并联后与继电器KM和变压器串联组成支路,该支路与继电器开关KM2并联后再与动断开关SB2串联组成所述开关。
正常使用前,使用者闭合动合开关SB1和动断开关SB2,动断开关SB2闭合后将该开关接入电路,动合开关SB1闭合后将继电器KM接入电路,然后动合开关SB1自动断出电路,继电器KM通电后开始工作,吸合继电器开关KM1、KM2,此时电流流经动断开关SB2、继电器开关KM2后流出,变压器、继电器KM、继电器开关KM1保持接通状态,动合开关SB1被断出电路,此时可正常供电工作。当突然停电时,继电器KM失去电流而停止工作,使得继电器开关KM1和KM2均断开,由于动合开关SB1已经断出电路,因此该开关电路均被断开,即使此时恢复供电,该开关也不会导通。变压器用于降低动合开关SB1和继电器KM支路的电压,防止动合开关SB1漏电时对人产生的危害。
与已有技术相比,本实用新型的有益效果为:设计合理、方便实用、安全可靠,停电后可自动断开电路,避免浪费电能,提高安全性。
附图说明    图1为本实用新型的电路示意图。
具体实施方式    在图1所示的本实用新型的电路示意图中,所述开关由继电器KM、变压器、动合开关SB1、动断开关SB2、继电器开关KM1、继电器开关KM2组成;动合开关SB1与继电器开关KM1并联后与继电器KM和变压器串联组成支路,该支路与继电器开关KM2并联后再与动断开关SB2串联组成所述开关。
