加熱管|單頭電熱管|引線|電極|結構

一、接殼單頭電熱管概述
A single head electric heat pipe, connected with the shell outline
接殼單頭電熱管結構:電熱管由一端引出單線,另一端與元件連接。 又為分軟線出頭、螺桿出頭、螺孔出線(直接用螺釘旋入接線端) 電壓:6-440V正常36V、55V 推薦規格:6︿14×60︿100
The shell single head electric heat pipe heating pipe line structure: by the end of lead, and the other end connected elements. And for the soft head, screw head, screw outlet (directly with the screw is screwed into the terminal voltage: 6-440V) normal 36V, 55V specification: 6 * 60 ^ 100 ^ 14
二、接殼單頭電熱管電阻的計算
Two, the calculation of shell single head electric heat pipe resistance
舉例:220V1500W’的電熱管
For example: 220V1500W’electric heating tube
P=1500瓦(功率) U=220伏(電壓) 求:I(電流)
P=1500 tile (power) U=220 V (voltage) ask: I (current)
I=P/U=1500/220≈6.82安
I=P/U=1500/220 = 6.82
歐姆定律 求:R(電阻)
Ohm’s law for: R (resistance)
R=U/I=220/6.82≈32.27歐
R=U/I=220/6.82 ≈ 32.27 Euro
三、電熱管的常用試驗及檢驗
Three, the electric heating tube of common test and inspection
1、電阻檢驗、冷態耐壓檢驗、冷態絕緣檢驗。
1, resistance test, cold pressure test, cold insulation test.
2、功率檢驗、熱態絕緣檢驗、熱態耐壓檢驗、泄漏電流檢驗。
2, power test, thermal insulation test, thermal pressure test, leakage current test.
3、潮態試驗、鹽霧試驗、壽命試驗及其它力學試驗。
3, the tide state test, salt spray test, life test and other mechanical test.
四、接殼單頭電熱管的性能要求
Performance requirements for four, with single head electric heat pipe shell
1 升溫時間在試驗電壓下,元件從環境溫度升至試驗溫度時間應不大于15min2 額定功率偏差在充分發熱的條件下,元件的額定功率的偏差應不超過下列規定的范圍;
1 heating time in the test voltage, components from the environment temperature to test temperature and time should be no more than 15min2 rated power deviation in the full heating conditions, scope of components of the power rating of deviation should be no more than the prescribed;
2、經受通斷電的能力元件應能在規定的試驗條件下經歷2000次通斷電試驗,而不發生損壞
The ability to withstand switching element 2, should be able to experience the 2000 on-off test in the test of the prescribed conditions, without the risk of damage
3、過載能力元件在規定的試驗條件和輸入功率下應承受30次循環過載試驗,而不發生損壞
3, overload ability element in the test conditions and input power should be subjected to 30 cyclic overload test, without being damaged
4、耐熱性元件在規定的試驗條件和試驗電壓下應承受1000次循環耐熱性試驗,而不發生損壞
4, heat resistance element in the test conditions and test voltage shall be subjected to 1000 cycles of heat resistance test, without being damaged
五、接殼單頭電熱管使用注意事項
Five, the shell single head electric heat pipe use matters needing attention
1、元件應存放于干燥外,若因長期放置而絕緣電阻降到低于1兆歐時,可在200℃左右的烘箱中干燥若干小時(或將元件低壓通過數小時),即或恢復絕緣電阻。
1, elements must be stored in a dry, if the long-term placement and insulation resistance is reduced to less than 1000000000000 in Europe, but in the oven at 200 ℃ drying in several hours (or low pressure through hours), or restoring insulation resistance.
2、發現管子表面有結碳時,必須除盡后再用,以免降低效率,甚至燒壞元件。
2, found the tube surface with carbon, to eliminate after use, so as not to reduce efficiency, and even burned element.
3、熔化瀝青、石蠟等固態油類時應降低電壓使用,等熔化后再升至額定電壓。以防止電量集中降低元件使用壽命。
3, melting asphalt, paraffin solid oils should reduce the voltage used to melt, then to the rated voltage. To prevent energy concentration reducing component life.
