KSD301系列突跳式温控器工作原理

温控开关,温控器工作原理(Operation Principle)

KSD301系列突跳式温控器(简称:KSD301温控器)是小型带外壳的双金属片温控器.属温度继电器类器件。利用碟型双金属片在温度作用下产生瞬间跳动的原理.通过机构的作用。使触点迅速动作,达到断开或接通电路的目的。其工作温度固定,无须调整:动作可靠干脆.电弧小;使用寿命长;无线电干扰少。
KSD301 snap action thermostat series is a small-size bimetal thermostat series with a metal cap,which belongs to thermal relays’family.The main principle is that one function of bimetal discs ls snap action under the change of sensing temperature.The snap action of disc can push the action of the contacts through the inside structure,then caused on or Off of the circit finally.The main characteristics are the fixation of working temperature,the reliable snap action,less flashover,longer working life and less radio interfernce

注意事项(Cautions)

1、温控器应工作于空气相对湿度不大干90%、无腐蚀性气体、可燃性气体和导电尘埃存在的一般室内环境。
2、温控器采用接触感温时。应使其封盖紧贴被控器具的发热部位。并应在封盖感温表面涂上导热硅脂或其他性能类
似的导热介质。
3、不可把封盏顶部压塌或使其变形。以免动作温度改变或影响其他性能。
4、不得让液体渗入温控器内部,壳体必须避免受到过大的力以防止出现裂纹;壳体应保持清洁。防止导电物质污染, 以免应绝缘性能降低而发生短路击穿。
5、手动复位产品在复位时力量不可过大,以刑能按下复位柄为宜。一般应小于20N,以免损坏温控器内部结构。
6、使用过程不能折弯接线端子。否则将影响电气连接的可靠性。
1.The thermostat should work in environments with humidity not higher than90%.free of caustic.flammable gas and conducting dust.
2.When the thermostat is used to sense the temperature of solid items.its covel should be clung to the heating part of such items.Meanwhile.heat-comducting stilicon grease or other media of similar nature should be applied in to the cover surface。
3.The top of the covel must not be pressed to sink or be distored so as to avoid adveres effect on the thermostat’s temperature sensitivity or its other functions.
4.Liquids must be kept out of the Thermostat’s inner part,The base must avoid any foree that could lead to crack;it should be kept clear and away from the pollution of electric substance to prevent insulation weakening that leads to shortclrcuited damages.
