溫控開關(guān)，溫控器工作原理(Operation Principle)

KSD301系列突跳式溫控器(簡稱:KSD301溫控器)是小型帶外殼的雙金屬片溫控器．屬溫度繼電器類器件。利用碟型雙金屬片在溫度作用下產(chǎn)生瞬間跳動的原理．通過機構(gòu)的作用。使觸點迅速動作，達(dá)到斷開或接通電路的目的。其工作溫度固定，無須調(diào)整：動作可靠干脆．電弧??；使用壽命長；無線電干擾少。
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

注意事項(Cautions)

1、溫控器應(yīng)工作于空氣相對濕度不大干90％、無腐蝕性氣體、可燃性氣體和導(dǎo)電塵埃存在的一般室內(nèi)環(huán)境。
2、溫控器采用接觸感溫時。應(yīng)使其封蓋緊貼被控器具的發(fā)熱部位。并應(yīng)在封蓋感溫表面涂上導(dǎo)熱硅脂或其他性能類
似的導(dǎo)熱介質(zhì)。
3、不可把封盞頂部壓塌或使其變形。以免動作溫度改變或影響其他性能。
4、不得讓液體滲入溫控器內(nèi)部，殼體必須避免受到過大的力以防止出現(xiàn)裂紋；殼體應(yīng)保持清潔。防止導(dǎo)電物質(zhì)污染， 以免應(yīng)絕緣性能降低而發(fā)生短路擊穿。
5、手動復(fù)位產(chǎn)品在復(fù)位時力量不可過大，以刑能按下復(fù)位柄為宜。一般應(yīng)小于20N，以免損壞溫控器內(nèi)部結(jié)構(gòu)。
6、使用過程不能折彎接線端子。否則將影響電氣連接的可靠性。
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．
