Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is refer to, the one kind for the photovoltaic module PID test devices that Fig. 1 is provided for the utility model embodiment is specific
The structural representation of implementation method；The annexation one of the earthing clamp that Fig. 2 is provided for the utility model embodiment and hold-down bars
Plant the structural representation of specific embodiment.
In a kind of specific embodiment, the photovoltaic module PID test devices, including
Support 10, the support 10 is used to place photovoltaic module to be tested, and the top of the support 10 is provided with fixation
Rod 20, is provided with two earthing clamps 30 on the hold-down bars 20, for connecting ground wire and the photovoltaic module to be tested
Ground hole；
Pin 40, the pin 40 is disposed or positioned on the support 10, in the photovoltaic module to be tested
After being placed into the support 10, the relative position of the photovoltaic module to be tested and the support 10 is fixed.
The photovoltaic module PID test devices, by the way that support 10 is integrated with earthing clamp 30, it is only necessary to by photovoltaic module
It is placed on support 10, is fixed using pin 40, the ground connection string holes of photovoltaic module, external test is being clamped using earthing clamp 30
The positive pole exit of positive source tryoff instrument connection coupling assembly is tested, simple, convenient, simple structure.While by
In screw and dead earth line need not be used, testing efficiency, Security of test are improve.
It is due to being integrated with support 10 and earthing clamp 30, it is only necessary to place the assembly on support 10 and solid with pin 40
It is fixed, and by a ground connection string holes for the clamping photovoltaic module of earthing clamp 30, another earthing clamp 30 clamps ground wire, it is possible to
External test power supply test.
In the utility model, two earthing clamps 30 on same hold-down bars 20 are electrically connected by hold-down bars 20.
Due to being directed to various sizes of photovoltaic module in test process, earthing clamp 30 is generally required relative to the position of hold-down bars 20
Change, therefore, typically grounded wire clamp 30 can be movable on hold-down bars 20, in a specific embodiment, the earthing clamp
30 are detachably connected with the hold-down bars 20.
Further, it is also possible to earthing clamp 30 is fixed on hold-down bars 20 using connecting line, as long as two earthing clamps 30
Between can be conductive.
In the utility model, hold-down bars 20 is provided on support 10, because photovoltaic module is vertical mode,
Mean hold-down bars 20 height can only than the test of photovoltaic module when numerical value it is highly high.The height of so support 10 is also necessary
Height when must similarly be tested than photovoltaic module to be tested is high so that the overall height of photovoltaic module PID test devices
Degree is higher, and mobile or transport is inconvenient, takes volume larger.
To save making material, because the side of support 10 need not support the weight of photovoltaic module substantially, can be by it
Be designed as it is telescopic between, i.e., launch in test, hold-down bars 20 rises, tested.Be completed, or transport,
Shunk during carrying, it is very convenient.
To further facilitate transport, the connection end of hold-down bars 20 and support 10 can also be designed as rotatably.Not
When being tested, hold-down bars turns to the side portable box with support, the bottom of whole stent collapses to support, so whole photovoltaic
The volume of component PID test devices becomes very small, almost be able to can just be carried with a tool box, very convenient, and
During test, photovoltaic module PID test devices are launched, hold-down bars 20 is turned into specified location and is fixed, then can just enter
Row is tested.
During due to module testing, typically can simultaneously each piece of photovoltaic module is tested, therefore the support 10 top
End is provided with many hold-down bars 20 be arrangeding in parallel.
Due to can typically set multiple hold-down bars 20, for convenience of managing, also for easy for installation, multiple can typically be fixed
Rod 20 is arranged on same installing frame, and then installing frame is installed on support, it is only necessary to adjust installing frame opposite brackets 10
Angle, very simply, conveniently.
In the utility model, the photovoltaic module being placed on support can be that placement can also dorsad be placed in the same direction,
It is general to manage for convenience, photovoltaic module is placed in the same direction.Disposably batch of photovoltaic module is placed on support, gear is used
Bar is fixed to photovoltaic module memory, rotates the installing frame for being used for installing hold-down bars, and then connection ground connection is empty can be tested.
During placing modules, because the frame of component may rub with the bottom of support 10, mill is caused
Damage so that the result of PID tests is inaccurate, to avoid the generation of this case, the support 10 includes being arranged on the rolling of bottom
Wheel 50, the rotation direction of the roller 50 is parallel with the axis direction of the hold-down bars 20.
Because polylith battery component placed side by side is tested simultaneously, rubbed to avoid adjacent battery component from contacting being formed
Wipe, or test result impacted, separating part is additionally provided with the roller 50, by the roller 50 be divided into it is described
The equal region of the quantity of hold-down bars 20.
In a kind of specific embodiment, the roller 50 is nylon roller.
For convenience of mobile support 10, the photovoltaic module PID test devices also include being arranged on the bottom of the support 10
Multiple rigid castors 60.Certainly, the photovoltaic module PID test devices are reached after precalculated position, it is necessary to castor is fixed, this
Sample can just reduce component or so, and vigorously dynamic generation to cell piece ruptures hidden danger.
In a kind of specific embodiment, the support 10 is stainless steel stent.
Certainly, in the utility model, the effect of support is to place and support to be test for photovoltaic module, with other parts
The photovoltaic module of placement is fixed, as long as ensureing enough mechanical strengths, the material to support is simultaneously not specifically limited.
In sum, the photovoltaic module PID test devices, by the way that support is integrated with earthing clamp, it is only necessary to by light
Volt component is placed on support, is fixed using pin, and the ground connection string holes of photovoltaic module, external test are being clamped using earthing clamp
The positive pole exit of positive source tryoff instrument connection coupling assembly is tested, simple, convenient, simple structure.While by
Testing efficiency, Security of test are improve in screw, dead earth line need not be used.
Photovoltaic module PID test devices provided by the utility model are described in detail above.It is used herein
Specific case is set forth to principle of the present utility model and implementation method, and the explanation of above example is only intended to help
Understand method of the present utility model and its core concept.It should be pointed out that for those skilled in the art,
On the premise of not departing from the utility model principle, some improvement and modification can also be carried out to the utility model, these improve and
