机械特性Mechanical characteristics
拉力强度试验Tensile test将保险丝固定好后,对保险丝引线施加5N的拉力,持续1分钟。试验过后,保险丝没有任何破损现象。Exert the axial pulling force of 5N to the both ends of lead wire for 1 minute. After the test the fuse shall be no damage and loosening. 电气特性Electrical characteristics实验条件Test condition所有测试环境温度为25±5℃。All electrical characteristics tests are conducted at an ambient temperature of 25±5℃.分断能力Interrupting rating test保险丝能承受的分断能力:35A或10倍的额定电流当中较大的。分断能力测试后测得保险丝的绝缘阻抗值大于0.1ΜΩ。The fuse interrupting capacity:35A or 10 times the rated current whichever is greater. After interrupting, the insulation resistance between the fuse terminations shall be not less than 0.1ΜΩ.3温度上升试验:通1.5倍额定电流15分钟,然后每隔15分钟增加0.1倍额定电流。测得保险丝断开时任何部位的温升不得超过135℃,周围环境温度为25±5℃。Temperature Rising Test: The rated current of 1.5 times is applied for 15 minutes. After the first 15minutes, the current is increased by 0.1 times the rated current every 15 minutes until the fuse operates. The temperature rising on the fuse surface is not higher than 135℃. 时间-电流特性 Time-Current Characteristics额定电流的% % of ampere rating 熔断时间 Opening time210%2 min Max275%400 ms~10 s400%150 ms~3 s1000% 20 ms~150 ms 耐久性测试 Endurance test 对保险丝通过相关标准规格单规定的额定电流1小时,然后截断电流15分钟,将该循环重复100次。试验过后保险丝没有任何破损现象。 A ampere rating specified in the relevant standard sheet is passed through the fuse for a period of 1h.The current is then switched off for a period of 15 minutes. This cycle is repeated 100 times. After the test the fuse shall be no damage and loosening.
