一、接壳单头电热管概述
A single head electric heat pipe, connected with the shell outline
接壳单头电热管结构:电热管由一端引出单线,另一端与元件连接。 又为分软线出头、螺杆出头、螺孔出线(直接用螺钉旋入接线端) 电压:6-440V正常36V、55V 推荐规格: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、接壳单头电热管电阻的计算
Two, the calculation of shell single head electric heat pipe resistance
举例:220V1500W’的电热管
For example: 220V1500W’electric heating tube
P=1500瓦(功率) U=220伏(电压) 求:I(电流)
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
欧姆定律 求:R(电阻)
Ohm’s law for: R (resistance)
R=U/I=220/6.82≈32.27欧
R=U/I=220/6.82 ≈ 32.27 Euro
三、电热管的常用试验及检验
Three, the electric heating tube of common test and inspection
1、电阻检验、冷态耐压检验、冷态绝缘检验。
1, resistance test, cold pressure test, cold insulation test.
2、功率检验、热态绝缘检验、热态耐压检验、泄漏电流检验。
2, power test, thermal insulation test, thermal pressure test, leakage current test.
3、潮态试验、盐雾试验、寿命试验及其它力学试验。
3, the tide state test, salt spray test, life test and other mechanical test.
四、接壳单头电热管的性能要求
Performance requirements for four, with single head electric heat pipe shell
1 升温时间在试验电压下,元件从环境温度升至试验温度时间应不大于15min2 额定功率偏差在充分发热的条件下,元件的额定功率的偏差应不超过下列规定的范围;
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、经受通断电的能力元件应能在规定的试验条件下经历2000次通断电试验,而不发生损坏
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、过载能力元件在规定的试验条件和输入功率下应承受30次循环过载试验,而不发生损坏
3, overload ability element in the test conditions and input power should be subjected to 30 cyclic overload test, without being damaged
4、耐热性元件在规定的试验条件和试验电压下应承受1000次循环耐热性试验,而不发生损坏
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、接壳单头电热管使用注意事项
Five, the shell single head electric heat pipe use matters needing attention
1、元件应存放于干燥外,若因长期放置而绝缘电阻降到低于1兆欧时,可在200℃左右的烘箱中干燥若干小时(或将元件低压通过数小时),即或恢复绝缘电阻。
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、发现管子表面有结碳时,必须除尽后再用,以免降低效率,甚至烧坏元件。
2, found the tube surface with carbon, to eliminate after use, so as not to reduce efficiency, and even burned element.
3、熔化沥青、石蜡等固态油类时应降低电压使用,等熔化后再升至额定电压。以防止电量集中降低元件使用寿命。
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.
