Description

一种漏电保护开关 技术领域
本发明涉及漏电保护装置技术领域，特别是涉及一种漏电保护开关。
背景技术
现有市内面上家庭使用的漏电保护开关，在使用当中，其漏电保护过程通常是通过串接在家用电网中，当连接于漏电保护开关的用电设备，其火线、或者零线存在漏电现象，零线、火线电流不平衡，漏电流大于漏电保护开关设定的限制电流，其限制电流参数，可参照相关的国家标准及行业标准，此时，漏电保护开关动作，断开漏电保护开关中的断路部件，使连接漏电保护开关的用电设备断开输入电源，从而确保人员使用用电设备时，起到安全防护的作用。目前城市部分旧的楼房及农村部分楼房，其家用电网没有安装地线，以及安装地线的楼房由于地线老化，导致家庭电网接地总线断路，当串接于漏电保护开关的用电设备的火线、或者零线碰触到用电设备的金属壳体，或者人体可触及的导电部件，此时现有漏电保护开关不会断开输入电源，从而会造成人员使用用电设备过程中存在安全隐患。
技术解决方案
本发明要解决的第一个技术问题是：如何使连接于漏电保护开关上的用电设备，在没有地线，或者地线断路的情况下，当其火线、或者零线碰触到用电设备的金属壳体，或者人体可触及的导电部件时，断开输入电源，确保用电设备的使用安全。为了解决上述技术问题，本发明所述漏电保护开关，其带电控制装置的测试端与地线端口电连接；带电控制装置的感测端经感测部件与零线、火线靠近组合，并相互绝缘；或者感测端经元件与零线、火线电连接。当漏电保护开关的地线端口带电时，带电控制装置可以输出控制信号给断路控制电路，断路控制电路控制断路部件断开，从而使得不论火线、还是零线触及用电设备的金属壳体，或者人体可触及的导电部件，漏电保护开关都会断开其输入电源。
本发明要解决的第二个技术问题是：如何使连接于漏电保护开关的用电设备，在家用电网地线总线断路情况下，其金属壳体碰触到其它电源端口的火线、或者零线时，确保漏电保护开关断开断路部件，从而避免用电设备的金属壳体带电，引起漏电保护开关的地线端口带电，造成连接家用电网其它用电设备连接地线的金属壳体也带电，影响其它用电设备使用的安全性。为了解决上述技术问题，本发明所述漏电保护开关，其带电控制装置的测试端与地线端口电连接；带电控制装置的感测端经感测部件与零线、火线靠近组合，或者感测端经元件与零线、火线电连接。以及漏电保护开关设有地线断路开关，从而使得连接于本发明漏电保护开关的用电设备，当其金属壳体碰触到与漏电保护开关并接的其它电源端口的火线或者零线，可以断开其地线断路开关，从而避免连接本发明漏电保护开关的用电设备金属壳体带电，引起家用电网中其它电源端口的接地线端口带电，从而降低人员使用用电设备的安 全隐患。
本发明要解决的第三个技术问题是：如何使连接漏电保护开关的用电设备，在正常工作的情况下，检测其金属壳体带电，漏电保护开关警示功能是否正常，同时还不影响用电设备的安全性。例如1：电冰箱通常采用压缩机制冷，其金属外壳与地线端口相连接，由于压缩机不可以频繁开启与关闭，否则容易损坏。在不用断开电冰箱的输入电源，测试电冰箱外壳带电时，检查漏电保护开关警示效果是否正常。例如2：在有限治疗仪器设备中，患者治疗过程中不能够断电，既要确保患者正常治疗，又必须对仪器进行检查，同时还不能因漏电伤害到患者，从而使治疗仪器利用率最大化，以及检查人员不必等待患者使用完治疗仪器后再检查，从而提高检查人员的工作效率。为了解决上述技术问题，本发明所述漏电保护开关，其带电控制装置的测试端经元件与地线端口电连接，带电控制装置的感测端经感测部件与零线、火线靠近组合，或者感测端经元件与零线、火线电连接。例如：带电控制装置的测试端设有测试开关A、电阻A、电阻D，感测端设有电阻D、电阻E；连通测试开关A，此时零线端口、火线端口分别经电阻D、电阻E，再通过测试开关A与测试端相连接，通过高阻抗电阻隔离，将火线端口、零线端口连接到用电设备金属壳体，此时的漏电流很小，在220V的市电中可以设置在0.01mA及以下，提示用户用电设备壳体带电，漏电保护开关警示功能正常；既不会对人体产生伤害，也不会导致外部串接的漏电保护开关动作，断开供电电源，影响用电设备正常使用。
本发明要解决的第四个技术问题是：如何使连接漏电保护开关的用电设备，在家用电网中有地线，或者没有地线时，当火线或者零线碰触到用电设备的金属壳体时，都要确保漏电保护开关断开断路部件，更好的确保用电设备使用的安全性。为了解决上述技术问题，本发明所述漏电保护开关，设有地线检测电路，控制开关，当检测到地线正常时，可以使用现有漏电保护开关零线、火线电流不平衡时，超过设定限制电流，断开断路部件；当检测到地线断路时，可以使用本发明所述带电控制装置电路，实现用电设备金属外壳碰触到零线或者是火线时，断开漏电保护开关的断路部件，更好的确保用电设备使用的安全性。
