4 电气特性:(Charactcrristics of Electrical Appliancos) |
4.1负载容量:额定电流测100%,能继续通电无任何熔化现象. |
4.1 Loading Capacity :The listed electrical (Included) add 100% for following,add it\'s |
available to let current kurrcnt.Keep on flowing without any melding. |
|
4.2温度特性:进行上项测试须1.5小时后继续维持原加之电流,每隔十分钟测试一次,连续测三次,温度不得 |
升高,若使用热偶式测量方法(Tbermocouple mcthod)则本体温升在70°C以下,若使用温度计测量方法 |
则在 50°C以下. |
4.2Temperature:Proceed the prcceding test for 1.5 houres ,Keep testing it with the original |
current every 10 minutes.Continue to test it for 3 times The temperature is not allowed to |
be higher The main temperature is below 70°C by way of Thermocouple Method While it keeps |
below 50°C by way of Thermometer Mcthod. |
|
4.3电阻测量:调整保险丝之额定电流达10%时,在保险丝两端使用高阻抗电压表测量降压值,以计算电阻值或 |
电桥方式测量(额定电流2.5安培含以上者,无须测量电阻值) |
4.3Resistance Measuring:Adjust the fuse upto listed electrical current 10%,we measure on two |
ends of the fuse with high voltage meter and caculare the resistance value with electrical |
brige way.(If the listed currecct equal or more the 2.5 Amp,it\'s not necessary to measure |
the resistance value) |

5. 机械特性(Mechanical Properties): |
乃经下述实验证明(Terminal Connections & Lead Solderability) |
|
5.1 拉力强度(Terminal Strength) |
当施加轴向拉力__1.1____磅于两端导线(或套盖)___5___分钟后,无松动或损坏现象发生. |
Lead and/or caps are soldcred(adhcrcd) to with stand axial pulling force of__1.1___pounds |
for___5___mine.without loosening or any harmfulness to firmly arlachment. |
|
5.2 回转强度(Torsion Strength) |
① 固定一端铜头,另一端施加720g/cm 的力左右摇动,铜头不得松动及发生任何本体的损坏. |
After being subjecteed to 720g/cm torsion to one cap while other terminal fixed ,no any |
damage or loosmning resulted. |
|
②一端导线弯折90度,本体以原轴旋转360度(5秒),三次不同方向之旋转后,导线或结合处不发生损坏. |
One lead bent through 90°the bady be clamped and rotated through 360°at a rate or(5 sec) |
about the original axis,Vophisical damage to leads or connections resulted after 3 time |
successive-altematero-tations. |
|
5.3 弯折强度(Bending Strength): |
导线经过两次反方向之弯折后(弯折90度同折回原位置之一次弯折)不发生损坏. |
After two bends of Opposite directions(bending through an angle of 90°and back is detined |
as one bond ) of lead ,Nodamage are to be visualized. |
