| 3. 材料(material) |
| 3.1 陶瓷管本体:陶瓷管清晰. |
| 3.1 glass tube:transparenr glass in
which the fuse is clear and perspectable .nobreaking or |
| deformation. |
| page1 of 3 |
| 3.2 两端铜盖:须以导电良好之黄铜底材料. |
| 3.2 tow brass and caps:made of brass
of good conductiviry. |
|
|
|
|
|
|
|
|
|
|
| 3.3 铜盖处理:铜盖部分镀镍 |
标示Zui后若加"s"者表示须镀银 |
| 3.3coating of brass caps plaring the
surfacc with nickel if the indicaron is added with "s". |
| it needs to be plared
with silver. |
|
|
|
|
|
|
|
|
|
|
| 3.4铜盖强度:铜盖和玻管本体间的扭力Zui小720g/cm. |
| 3.4slrength of brass caps:the minimum
tortion beteen brass caps and glass tube is 720g/cm. |
|
| 4 电气特性:(charactcrristics of
electrical appliancos) |
| 4.1负载容量:额定电流测,能继续通电无任何熔化现象. |
| 4.1 loading capacity :the listed
electrical (included) add 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. |
