結構特點Featur or structure

KSD-9700系列熱保護器是由碟形高靈敏雙金屬元件、動觸頭、靜觸片、固定底座、外殼、耐溫導線等組成。工作時雙金屬元件處于自由狀態(tài)，動觸頭與靜觸片閉合，電路導通。當使用電器因故障發(fā)熱而使溫度上升至熱保護器的動作溫度時，雙金屬元件受熱產(chǎn)生內(nèi)應力而動作，推開動觸頭離開靜觸片而斷開電路，從而切斷故障電器電源起到保護電器作用。當被保護電器溫度下降到熱保護器的額定復位溫度值時，雙金屬元件恢復到初始狀態(tài)觸點閉合，電器恢復正常工作。該產(chǎn)品具有電阻小、感溫快、動作、、體積小等優(yōu)點。

   KSD-9700 seri thermal protector consists of dish shape high sensitive bimetallic elemeng,movable contact-head,static contact-piece,soleplate,outer case,ghermal ristant lead and so on.When operation,the bimetallic element is in free state and movable contact-head and static contace-piece are closed and the circuit is on.When the electric appliance is in operation is in operation and produc heat caused by some troubl and temperature is raised to the rated action temperature of the product,the bimetallic element produc inner stus and acts quickly and push the movable contact-head and make the vontact point off and the power supply is rurned off the electric appliance s.in this way the thermal protection is made.When the temperature of electric appliance to be protected is dropped to the rated ret temperature.The bimetallic element rtor to its primary state and contact point is closed .The electric appliance rtor its work.The product has many advantag such as all in ristor,puick in temperature feeling,fast in action.Safe and reliable.compact and so on.

應用范圍Product application

溫度檢測方法：將試樣兩引線分別接在測試設備的夾具上，通上10mA左右的電流（不過100mA），用一發(fā)光二管指示電流的通斷，然后將試樣放入測溫設備內(nèi)，（測試設備內(nèi)溫度應均勻，加熱升溫速度可控制）溫度計探頭應貼近試樣，控制檢測設備溫度以0.5～1℃/min的速率升溫,當發(fā)光二管熄滅時,記下溫度計讀數(shù)即為試樣的動作溫度。

TT METHOD:Sample is connected to the fixture of the equipment,and placed into the tt equipment (Hot current of air in the space of tt should be equipped with a stirrer and temperature is controllable).A detect current about 10mA(no more then 100mA)is ped through the sample and a thermometer is placed junction to the sample to monitor the opening temperature .The temperature of the tt equipment is raised at the rate of 0.5～1℃ per minute until the sample functioned.
