The single-phase three-phase fireproof power saving switch is a power switch for electronic monitoring, remote control, power supply, overload, short circuit, leakage protection, tripping and closing. No electrical sparks are generated when the trip is switched on and the electric contacts are burned out. Switch can overload or short-circuit trip protection, can reduce the power failure caused by fire more than 90%, reduce inductive load, reactive power loss 30%. Every year hundreds of millions of power users in the country to save hundreds of billions of electricity bills. The main points of the switch principle is that when the power is overloaded or shorted, the large current induces the VK voltage. In 1/50 seconds, the electromagnetic switch is tripped by an electric spark, and no fire is caused. This switch reduces annual casualties of thousands of fires, and reduces property losses by several billion yuan, which is unprecedented, great progress in the power industry. Fire protection and energy saving switch is a new type of electric appliance which combines energy saving, environmental protection, disaster prevention and disaster reduction. Because of the technology high grade products, can be sold all over the world for years, sales of billions, hundreds of billions of yuan output value.

技术介绍
闸刀保险丝20年前国内外家庭用电开关大都是闸刀串保险丝,大多数用电家庭 不能正确安保险丝,把保险丝加大几倍使用,一旦供电线路短路或过载大电流,保险丝不能 快速熔断,就会引发电火灾害。空开电源开关20年前国内外出现了叫“空开”的电源开关,空开是仿制用了上百 年的“马达起动开关”中的螺线管短路大电流吸起电磁性杆冲动弹簧来跳闸保护用电器的。 空开要有20-30A大电流才跳闸保护。由于“空开”结构是多个弹簧相串连接而成,可靠性 差,加上跳闸,合闸大电流有很强的电火花烧蚀电触点,有时不跳闸等等防火性能差。空开没有过载电流大小调节,更没有功率因素补偿节电的高性能,老空开应更新 换代用“防火节电开关”,为全国和世界防火节电也是我们研发“防火节电开关”的目的。发 明内容本“防火节电开关”带有电子监控遥控,当用电线路或电器发生过载或短路漏电 时,在1/50秒内电磁双向开关跳闸断开电源供电,保护线路及用电器。断开电源不产生火 花烧坏触点。本开关能减少用电故障引发的火灾90%以上。本开关具有功率因素调节功 能,因而可减少感性无功损耗30%,提高供电设备多供电30%,这对节能减排贡献巨大,每 年在全国5亿个用电家庭和工业节省电能上仟亿元以上。本“防火节电开关”最基本原理如图1的防火节电开关监控线路原理图用来电子 监控,遥控电源过载、短路、漏电、跳闸、合闸的电源开关。本单相开关工作原理是由图2组合控制单相开关,由图3组合三相开关,A、B、C 三相中任和一相发生用电过载或短路时,其大 ...
