HKW9700-D-E系列熱保護(hù)器
HKW9700-D-E型熱保護(hù)器具有體積小、外殼絕緣、動(dòng)作靈敏、壽命長(zhǎng)等特點(diǎn)，
適用于新能源電池，電機(jī)、電源，光燈鎮(zhèn)流器、變壓器、汽車馬達(dá)、集成電路及
一般電氣設(shè)備的過(guò)熱過(guò)流雙重保護(hù)作用。
HKW9700-F-H thermal protector has small dimension; insulation shell;
sensitive and long life time. Its widely use in new energy battery;
motor; power; ballast; transformer;integrated circuit and
electrical equipment’s overheat and overload double protection.
2結(jié)構(gòu)特點(diǎn)Structural features
HKW9700-D-E系列熱保護(hù)器是采用一定幾何形狀的雙金屬片，無(wú)需輔助機(jī)構(gòu)，僅靠雙金屬片的自身感溫和電流熱效應(yīng)，使雙金屬元件的狀態(tài)發(fā)生快速變化，直接帶動(dòng)觸點(diǎn)實(shí)現(xiàn)自動(dòng)切斷和接通電路，起到過(guò)熱、過(guò)載保護(hù)作用。
HKW9700-F-G thermal protector use unique bimetal and don’t need more auxiliary parts. Using bimetal Self-sensing temperature and Current thermal effect to change the bimetal’s shape to control the electric circuit cut off or contact on. Overheat and overload double protection.
