温控加热管|电热棒|发热管|选购|作用

随着科学的发展,时代的 进步经济全球化的今天,人们的 生活质量不断提高,对家电产品的造型、功能,特别是 安全性要求越来越高。目前,具有热保护功能的电加热管电热管的过热保护功能)产品广 泛应用在充气式便携浴缸、电热油汀、电热水器等产品中。具有热保护功能的电加热管起到了 产品的温度控制及过热安全保护作用。

具有热保护功能的电加热管电热管的过热保护功能)大部分 采用热熔断器又称温度保险丝来作为控制器件,当电热管工作温 度超过热熔断器的额定温度时,热熔断器能迅速中断电热管的通电电路,避免电热管过热产生的火灾及电热管损毁等危害。

电热管的过热 保护热熔断器的特征:具有一 次性动作切断电流,电流中断能力达250 VAC/25A,电阻值低,尺寸小。
电热管的过热 保护功能热熔断器的工作原理:热熔断 器的有效触发机件是一粒由独特配方制成的不导电热敏丸。在正常的操作温度下,固态的 热敏丸顶住弹簧,使触点保持接触。当达到 某一预定的温度时,热敏丸会熔化,使得压缩弹簧放松,而断路 弹簧便推动触点离开接触引线,电路就被断开。

With the development of science, the progress of the era of economic globalization today, constantly improve people’s quality of life, the electrical appliances product modeling, function, especially the safety requirements more and more high. At present, with thermal protection function of the electric heating tube 电加热管(overheating protection function of the electric heating pipe) 电热管的过热保护功能are widely applied in the portable inflating bathtub, electric oil heater, electric water heaters and other products. With thermal protection function of the electric heating tube to temperature control and overheat safety protection products.

With heat protection function of the electric heating tube电加热管 (overheating protection function of the electric heating pipe) 电热管的过热保护功能most of the use of thermal fuse and fuse as temperature control device, when the rated temperature of electric heating tube over heat fuse, thermal fuse can quickly break through electric circuit of the electric heating pipe heating pipe, to avoid overheating fire and electric heating tube damage hazards.
Characteristics of hot electric heat pipe thermal fuse protection: one-time action to cut off the current, current interruption capacity of up to 250 VAC/25A, low resistance, small size.
Electric heating tube overheating protection thermal fuse works: thermal fuse trigger mechanism is not conductive thermal a unique formula made by the pill. At normal operating temperature, pellet solid against the spring, the contact contact. When it reaches a predetermined temperature, thermal pill will melt, the compression spring to relax, and break the spring drives the contact point from the contact wire, the circuit is disconnected.
