RS-9700熱保護(hù)器RS-9700SeriesThermalProtector結(jié)構(gòu)特點FeaturesorstructureRS-9700系列熱保護(hù)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(dǎo)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(dǎo)通。當(dāng)使用電器因故障發(fā)熱而使溫度上升至熱保護(hù)器的動作溫度時，雙金屬元件受熱產(chǎn)生內(nèi)應(yīng)力而迅速動作，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(hù)電器作用。當(dāng)被保護(hù)電器溫度下降到熱保護(hù)器的額定復(fù)位溫度值時，雙金屬元件恢復(fù)到初始狀態(tài)觸點閉合，電器恢復(fù)正常工作。該產(chǎn)品具有電阻小、感溫快、動作迅速、安全可靠、體積小等優(yōu)點。 RS-9700seriesthermalprotectorconsistsofdishshapehighsensitivebimetallicelemeng,movablecontact-head,staticcontact-piece,soleplate,outercase,ghermalresistantleadandsoon.Whenoperation,thebimetallicelementisinfreestateandmovablecontact-headandstaticcontace-pieceareclosedandthecircuitison.Whentheelectricapplianceisinoperationisinoperationandproducesheatcausedbysometroublesandtemperatureisraisedtotheratedactiontemperatureoftheproduct,thebimetallicelementproducesinnerstuessandactsquicklyandpushesthemovablecontact-headandmakethevontactpointoffandthepowersupplyisrurnedofftheelectricappliancestop.inthiswaythethermalprotectionismade.Whenthetemperatureofelectricappliancetobeprotectedisdroppedtotheratedresettemperature.Thebimetallicelementrestorestoitsprimarystateandcontactpointisclosed.Theelectricappliancerestoresitswork.Theproducthasmanyadvantagessuchassmallinresistor,puickintemperaturefeeling,fastinaction.Safeandreliable.compactandsoon.應(yīng)用范圍Productapplication適用于各種家用電器和電子產(chǎn)品。如馬達(dá)、日光燈鎮(zhèn)流器、電池充電器、變壓器、園筒形線圈、電蒸氣浴機(jī)、電熱水器、辦公自動化設(shè)備等的過熱保護(hù)。Beapplicabletoallkindsofhomeappliancesandelectronicsproducts.SuchasElectricMotors,FluorescentBallasts,BatteryChargers,Transformers,Solenoids,Heatingpads,OA-MachinesETC.技術(shù)參數(shù)Technicalparameters:動作溫度Actiontemperature復(fù)位溫度Resettemperature 動作溫度Actiontemperature復(fù)位溫度Resettemperature45+/-5℃40+/-6℃105+/-5℃80+/-15℃50+/-5℃43+/-6℃110+/-5℃80+/-15℃55+/-5℃45+/-6℃115+/-5℃85+/-15℃60+/-5℃50+/-10℃120+/-5℃90+/-15℃65+/-5℃50+/-10℃125+/-5℃95+/-15℃70+/-5℃50+/-10℃130+/-5℃100+/-15℃75+/-5℃55+/-10℃135+/-5℃105+/-15℃80+/-5℃55+/-10℃140+/-5℃110+/-15℃85+/-5℃55+/-10℃145+/-5℃115+/-15℃90+/-5℃60+/-10℃150+/-5℃120+/-15℃95+/-5℃65+/-10℃155+/-5℃125+/-15℃100+/-5℃75+/-10℃160+/-5℃130+/-15℃特殊規(guī)格可根據(jù)客戶要求定做Thespecificationcanalsobemanufacturedasrequest.額 定電壓 RatedVoltage:AC250V/AC125V;額 定電流 RatedCurrent:1~10常態(tài)電氣強(qiáng)度 Electricintensity:﹥800V常態(tài)接觸電阻 Contactresistance:﹤30m?絕 緣電阻 Lnsulationresistance:﹥100M?響 應(yīng)速度 Responsespeed:≦1℃/min壽 命次數(shù) Numberofautomaticcycles:﹥6000(阻抗負(fù)荷ResistiveLoad)溫度檢測方法：將試樣兩引線分別接在測試設(shè)備的夾具上，通上10mA左右的電流（不超過100mA），用一發(fā)光二極管指示電流的通斷，然后將試樣放入專用測溫設(shè)備內(nèi)，（測試設(shè)備內(nèi)溫度應(yīng)均勻，加熱升溫速度可控制）溫度計探頭應(yīng)貼近試樣，控制檢測設(shè)備溫度以0.5～1℃/min的速率升溫,當(dāng)發(fā)光二極管熄滅時,記下溫度計讀數(shù)即為試樣的動作溫度。TESTMETHOD:Sampleisconnectedtothefixtureoftheequipment,andplacedintothetestequipment(Hotcurrentofairinthespaceoftestshouldbeequippedwithastirrerandtemperatureiscontrollable).Adetectcurrentabout10mA(nomorethen100mA)ispassedthroughthesampleandathermometerisplacedjunctiontothesampletomonitortheopeningtemperature.Thetemperatureofthetestequipmentisraisedattherateof0.5～1℃perminuteuntilthesamplefunctioned.
