PV引出端强度试验机/光伏组件引出端强度试验机
一、IEC 61215-2005标准
引出端强度试验
10.14.1 目的
确定引出端及其与组件体的附着是否能承受正常安装和操作过程中所受的力。
10.14.2 引出端类型
考虑三种类型的组件引出端:
— A型:直接自电池板引出的导线;
— B型:接线片、接线螺栓、螺钉等;
— C型:接插件。
10.14.3 程序
预处理:在标准大气条件下进行1h的测量和试验。
10.14.3.1 A型引出端
拉力试验:如GB/T 2423.29 Ua的试验所述,满足下列条件:
— 所有引出端均应试验;
— 拉力不能超过组件重量。
弯曲试验:如GB/T 2423.29 Ub的试验所述,满足下列条件:
— 所有引出端均应试验;
— 用方法1实施10次循环(每次循环为各相反方向均弯曲一次)。
10.14.3.2 B型引出端
拉力和弯曲试验:
a) 对于引出端曝露在外的组件应与A型引出端的试验一样,试验所有引出端;
b) 如果引出端封闭于保护盒内,则应采取如下程序:
— 将组件制造厂所推荐型号和尺寸的电缆切为合适的长度,依其推荐方法与盒内引出端相接,利用所提供的电缆夹小心将电缆自密封套的小孔中穿出。盒盖应牢固放置原处,再按A型引出端的试验方法进行试验。
转矩试验:如GB/T 2423.29 Ud的试验所述,满足下列条件:
— 所有引出端均应试验;
— 严酷度1。
除固定的指定设计外,螺帽、螺丝均应能松启。
10.14.3.3 C型引出端
将组件制造厂推荐型号和尺寸的电缆切为合适的长度与接插件线盒输出端相接,然后按与A型引出端相同的试验方法进行试验。
10.14.4 最后试验
重复试验10.1和10.2。
10.14.5 要求
应满足下列要求:
— 无机械损伤现象;
— 输出功率的衰减不超过试验前测试值的5%;
绝缘电阻应满足初始试验同样的要求。
IEC 61215-2005 standard
Terminal strength test
The purpose of 10.14.1
Determination of terminal attachment and assembly body whether can bearnormal installation and operation of the force.
10.14.2 terminal types
Consider three types of component terminations:
A: direct self lead battery plate leads;
B type: lugs, connecting bolts, screws etc.;
C type: socket connector.
The 10.14.3 program
Pretreatment: Measurement and test of 1H in standard atmospheric conditions.
10.14.3.1 A terminal
Pull test: Test of GB/T 2423.29 Ua said, meet the following conditions:
All terminations shall test;
Pull can not exceed the weight of components.
Bending test: Test of GB/T 2423.29 Ub said, meet the following conditions:
All terminations shall test;
1 implementation of the 10 cycles (each cycle method for the opposite directionof bending a).
10.14.3.2 B terminal
Tension and bending test:
A) for the test component terminations exposed and A terminations, test allterminations;
B) if the end is enclosed in the protective box, should adopt the followingprocedure:
The cable factory assembly recommended types and sizes of cutting to length,according to the recommended method and box end connected, clip carefullycable from small seal in using the cable provided. The cover shall be firmlyplaced in place, test method according to the A terminal test.
Torque test: Test of GB/T 2423.29 Ud said, meet the following conditions:
All terminations shall test;
- severity 1.
In addition to the specified design permanently fixed to the outer, nuts, screws are loose and should be able to.
10.14.3.3 C terminal
The cable assembly factory recommended types and sizes of cutting withappropriate length and output connector line box, and then press test method forthe same leads end and A test.
10.14.4 final test
The test was repeated 10.1 and 10.2.
10.14.5 requirements
Shall meet the following requirements:
No mechanical damage phenomenon;
Decay of maximum output power does not exceed the test before the test value of 5%;
Insulation resistance shall meet the requirements of initial trials of the same.
