Description
Technical field
It the utility model is related to battery line production auxiliary detection technique, the especially solar cell in photovoltaic apparatus equipment
Testing lines device.
Background technology
Generally the wiring system for connecting photovoltaic module and inverter will not be considered as critical component, still, failing to adopting
With the private cable of application of solar energy, it will have influence on the service life of whole system.
Solar cables are a kind of beam crossover link cables, and rated temperature is 120 DEG C, can be resisted in corresponding device
Extreme climate environment and it is subjected to mechanical shock.According to international standard IEC216, solar cables, in outdoor environment, it is used
Life-span is 8 times of rubber cable, is 32 times of PVC cables.These cables and part not only have optimal weather resistance, resistance to purple
Outside line and ozone attack, and can bear larger range of temperature change (such as：From -40 DEG C to 125 DEG C).In solar energy
It is necessary in system using special solar cable and part.
For photovoltaic application, the material that open air uses should be according to ultraviolet, ozone, dramatic temperature change and chemical erosion
Depending on situation.Low-grade material is used under this kind of environmental stress, cable cover(ing) will be caused frangible, or even cable insulation can be decomposed
Layer.All these situations all can directly increase cable system loss, while the risk that cable short circuit occurs can also increase, Cong Zhongchang
Phase sees that the possibility that fire or personnel's injury occurs is also higher.
In fact, during installation and maintenance, cable can connect up on the sharp edge of roof structure, while cable must bear to press
Power, bending, tension force, it is stretched across load and brute force attack.If cable cover(ing) insufficient strength, cable insulation will be by
It is badly damaged, so as to influence the service life of whole cable, or cause short circuit, fire and personnel to injure going out for the problems such as dangerous
It is existing.
The characteristic of photovoltaic cable is determined by its cable special isolation material and protective cover material, and we term it crosslinking PE, warp
Cross after irradiation accelerator irradiation, the molecular structure of CABLE MATERIALS can change, so as to provide the performance of its aspect.Resistance to mechanical
In fact, during installation and maintenance, cable can connect up load on the sharp edge of roof structure, at the same cable must bear pressure,
Bending, tension force, it is stretched across load and brute force attack.If cable cover(ing) insufficient strength, cable insulation will be by tight
Damage again, so as to influence the service life of whole cable, or cause short circuit, fire and personnel to injure going out for the problems such as dangerous
It is existing.

T2951.31-2008)；Temperature (140 ± 3) DEG C, time 240min, k=0.6, depth of cup are no more than insulation and sheath total thickness
The 50% of degree.And carry out AC6.5kV, 5min voltage test, it is desirable to do not puncture.Sample is in 90 DEG C of temperature, relative humidity 85%
1000h is placed under environment, is cooled to after room temperature compared with before experiment, tensile strength change≤- 30%, the change of elongation at break
Rate≤- 30%.Acid and alkali-resistance solution trial (GB/T 2951.21-2008), two groups of samples are dipped in the grass that concentration is 45g/L respectively
In acid solution and the sodium hydroxide solution that concentration is 40g/L, temperature is 23 DEG C, time 168h, and compared with soaking before solution, tension is strong
Spend rate of change≤± 30%, elongation at break >=100%.Low-temperature impact test (8.5 in GB/T 2951.14-2008) will
Ask, -40 DEG C of chilling temperature, time 16h, quality of dropping hammer 1000g, impact block quality 200g, height of drop 100mm, surface should not
There is eyesight visible crack.Low temperature bend test (8.2 in GB/T 2951.14-2008) requirement, chilling temperature (- 40 ± 2) DEG C,
Time 16h, 4~5 times of a diameter of outside diameter of cable of coupon, around 3~4 circles, jacket surface should not have eyesight visible crack after experiment.
Due to no special test equipment, at present, solar cables test implementation method is with light tight test box, tune
