JNYC系列永磁及防晃电交流接触器
J恒压交流接触器工作原理:恒压式交流接触器是用恒压控制板驱动经过改进的电磁铁机构而形成的一种新型微功耗接触器。其工作原理就是:交流吸合,直流保持。瞬间通电时,恒压控制板驱动线圈一个220V的吸合电压,在吸合的瞬间切换成DC5V给线圈供电。传统接触器的缺点:1:电压跌落到正常工作电压80%就处于临界状态,跌落到80%以下就造成接触器断开。2:电压不稳定造成线圈噪音及发热,从而引发温升,使接触器线圈烧毁3:由于主触头振动卡住,造成触头短路烧毁。4:合闸线圈长期通电,严重消耗电能恒压交流接触器的优点:1,可靠性、动作频率与寿命(不会触头卡住烧毁)由于恒压控制板的原理,恒压交流接触器避免因电磁线圈温度过高烧掉绝缘漆造成短路现象,从而影响生产,造成危害。其吸合与释放是传统交流接触器的2~3倍,而且在额定电压30%~~130%电压波动范围内,仍能可靠吸合。其吸合释放动作干净、不打颤。由于线圈的保持始终是DC5V,所以不存在电压不稳造成触头打颤产生电弧使触头溶蚀而无法释放以及触头卡死造成触头短路烧毁的现象。其工作频率远超传统接触器,是在行车正反转等高频率、恶劣环境中使用的***佳选择。2,节电率大于90%传统接触器是通过线圈的持续通电来保持线圈的磁性才能起到吸合的作用,所以传统接触器在吸合的过程中持续的保持电流的通过,持续的消耗大量的电能,而恒压交流接触器在通电一刹那即切换成DC5V来维持接触器线圈的吸合,只需要很小的保持电流,释放时只需要切断电源即可完全释放。3,不受网电压波动影响,可选择释放电压。交流接触器在低压电动机控制系统中的应用非常广泛,占了相当大的比例。由于电磁式交流接触器的工作原理特点,当电网出现晃时,会造成电磁或交流接触器工作线圈短时断电或电压过低,导致靠电流维持吸的动、静铁芯吸力小于释放弹簧的弹力,使接触器释放产生跳闸停机的重要原因。电磁式交流接触器的动作特性:国际IEC标准规定、额定电压的80%为临界可靠吸合电压。临界释放电压为额定工作电压的20—70%现场使用中电磁式交流接触器一—般在标称的电压50%释放,所以因“晃电”导致电磁式交流接触器不受控制而自然跳闸停机是原理所致。恒压接触器的吸合电压为额定电压70%-130%,而保持吸合的电压为额定电压30%-130%,也可定制。所以恒压接触器不因为外部电压的变化而造成断开,影响生产。NYC-3F/1A,JNYC-3F/1B,JNYC-3F/1C,JNYC-3F/1D,JNYC-3F/1E,JNYC-3F/1F,JNYC-3F/1H,JNYC-3F/2A,JNYC-3F/2B,JNYC-3F/2C,JNYC-3F/2D,JNYC-3F/2E,JNYC-3F/2F,JNYC-3F/3A,JNYC-3F/3B,JNYC-3F/3C,JNYC-3F/4D,JNYC-3F/4E,JNYC-3F/5H,JNYC-3F/1A-KS,JNYC-3F/1B-KS,JNYC-3F/1C-KS,JNYC-3F/1D-KS,JNYC-3F/1E-KS,JNYC-3F/1F-KS,JNYC-3F/1H-KS,JNYC-3F/2A-KS,JNYC-3F/2B-KS,JNYC-3F/2C-KS,JNYC-3F/2D-KS,JNYC-3F/2E-KS,JNYC-3F/2F-KS,JNYC-3F/3A-KS,JNYC-3F/3B-KS,JNYC-3F/3C-KS,JNYC-3F/4D-KS,JNYC-3F/4E-KSJNYC-3F/5H-KS,JNYC-1S/1A,JNYC-1S/1B,JNYC-1S/1C,JNYC-1S/1D,JNYC-1S/1E,JNYC-1S/1F,JNYC-1S/1H,JNYC-1S/2A,JNYC-1S/2B,JNYC-1S/2C,JNYC-1S/3A,JNYC-1S/3B,JNYC-1S/4D,JNYC-1S/4E,JNYC-1S/5H,JNYC-1S/1A-KS,JNYC-1S/1B-KS,JNYC-1S/1C-KS,JNYC-1S/1D-KS,JNYC-1S/1E-KS,JNYC-1S/1F-KS,JNYC-1S/1H-KS,JNYC-1S/2A-KS,JNYC-1S/2B-KS,JNYC-1S/2C-KS,JNYC-1S/3A-KS,JNYC-1S/3B-KS,JNYC-1S/4D-KS,JNYC-1S/4E-KS,JNYC-1S/5H-KS,JNYC-4F/1A,JNYC-4F/1B,JNYC-4F/1C,JNYC-4F/1D,JNYC-4F/1E,JNYC-4F/1F,JNYC-4F/2A,JNYC-4F/2B,JNYC-4F/2C,JNYC-4F/2D,JNYC-4F/2E,JNYC-4F/2F,JNYC-4F/3A,JNYC-4F/3B,JNYC-4F/3C,JNYC-4F/3D,JNYC-3U/1A,JNYC-3U/1B,JNYC-3U/1C,JNYC-3U/1D,JNYC-3U/2A,JNYC-3U/2B,JNYC-3U/2C,JNYC-3U/3A,JNYC-3U/3B,JNYC-3U/3C,JNYC-3U/4A,JNYC-1U/1A,JNYC-1U/1B,JNYC-1U/1C,JNYC-1U/1D,JNYC-1U/2A,JNYC-1U/2B,JNYC-1U/2C,JNYC-1U/2D,JNYC-1U/3A,JNYC-1U/3B,JNYC-1U/3C,JNYC-1U/3D,JNYC-1U/4A,JNYC-1U/4B,JNYC-1U/4C,JNYC-1U/4D,JNFH-A,JNFH-B,JNFH-E-I,JNFH-E-II)
