Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, specifically to a novel testing fixture for a photovoltaic combiner monitoring device. Background Technology

[0002] The description of the background technology in this utility model pertains to related technologies and is used merely for illustration and to facilitate understanding of the content of this utility model. It should not be construed as the applicant explicitly believing or presuming that the applicant believes it to be prior art on the filing date of the first application.

[0003] During the commissioning phase, the photovoltaic combiner monitoring device needs to calibrate the current. The calibration method is to use a standard source to increase the current of each current sampling channel, and then the core unit collects the analog quantity of each channel and processes the data to make the current displayed by the device consistent with the actual value.

[0004] The structure of existing test fixtures is as follows Figure 1-4 As shown, due to the directional nature of the current input to the sampling module of the photovoltaic combiner monitoring device, the current input to the initial side of the first copper rod needs to be led back to the initial side of the second copper rod via a wire, and the end side of the second copper rod needs to be led back to the initial side of the third copper rod via a wire, and so on. In this way, each current sampling channel needs to be connected to a wire. The large number of wires placed in the storage box makes it necessary to exert a certain amount of force each time the moving beam is pulled. Moreover, long-term and repeated testing may lead to poor wire contact and other problems, affecting the reliability and lifespan of the testing fixture. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a novel testing fixture for photovoltaic combiner monitoring devices. This novel testing fixture for photovoltaic combiner monitoring devices has a simple structure, can perform large-scale testing, and is reliable and durable.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A novel photovoltaic combiner monitoring device testing fixture includes: a testing fixture body, slide rails on both sides of the testing fixture body, and two movable beams that can slide along the slide rails. Corresponding copper rods are fixed to the two movable beams, with terminals at both ends of each copper rod. The copper rods are divided into upper and lower layers, with each layer corresponding to the previous one. The ends of the upper and lower layers of copper rods are connected to the ends of the corresponding copper rods in the other layer. The beginning of the upper layer copper rod is connected to the beginning of the next adjacent lower layer copper rod. The beginning of the first lower layer copper rod and the beginning of the last upper layer copper rod are connected to the two ends of a standard power supply.

[0008] Furthermore, a positioning beam is provided above the slide rail.

[0012] By employing the above-described solution, this utility model possesses at least the following beneficial effects:

[0013] This invention eliminates the need for a wire storage box, saving the back-and-forth wiring for each copper rod. With fewer wires, the force required to push and pull the copper rods along the guide rail is reduced, making testing convenient and quick. The simplified fixture structure, resulting in greater reliability and durability, is also due to the reduced wiring. The sampling module is divided into upper and lower layers, increasing the number of sampling modules that can be tested simultaneously. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the embodiments are for the purpose of making it easier for those skilled in the art to understand the technical solution of the present invention, and should not be regarded as limiting the scope of protection of the present invention.

[0024] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of the present invention, which can be substituted or combined with each other. Therefore, the present invention can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present invention should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0025] Combined with appendix Figure 1-8 The existing testing fixture operates as follows: The movable beam 2 is opened, the photovoltaic combiner monitoring device current sampling module is placed inside, and then the movable beam 2 is closed to ensure good contact between the copper rods 3 on both sides. A standard current is applied to the copper rods 3 using a standard source, and the sampling module collects the corresponding current value and processes the data.

[0026] Because the current input of the sampling module of the photovoltaic combiner monitoring device is directional, the current added to the initial side of the first copper rod 3 needs to be led back to the initial side of the second copper rod 3 by a wire, and the end side of the second copper rod 3 needs to be led back to the initial side of the third copper rod 3 by a wire, and so on. In this way, each current sampling channel needs to be connected to a wire. A large number of wires are placed in the wire storage box 7, which makes it necessary to exert a certain force each time the moving beam 2 is pulled. Moreover, long-term and repeated testing may lead to poor wire contact and other problems, affecting the reliability and life of the testing fixture.

[0027] The present invention provides a novel testing fixture for a photovoltaic combiner monitoring device, comprising: a testing fixture body, on both sides of the testing fixture body being provided with slide rails 1, and on the slide rails 1 being provided movable beams 2 that can slide along the slide rails 1, there being two movable beams 2, and on each of the two movable beams 2 being fixed corresponding copper rods 3, the two ends of the copper rods 3 being terminals 5, the copper rods 3 being divided into upper and lower layers, the upper and lower layers of copper rods 3 being one-to-one, the ends of the upper and lower layers of copper rods 3 being connected to the ends of the copper rods 3 of the other layer corresponding to them; the beginning of the upper layer of copper rods 3 being connected to the beginning of the next adjacent lower layer of copper rods 3; the beginning of the first copper rod 3 of the lower layer and the beginning of the last copper rod 3 of the upper layer being connected to the two ends of a standard power supply respectively.

[0028] In some embodiments, a positioning beam 4 is provided above the slide rail 1.

[0029] In some embodiments, the number of copper rods 3 in both the upper and lower layers is 12.

[0030] In some embodiments, the movable beam 2 is provided with a handle 6.

[0031] In some embodiments, the current sampling module is divided into two groups, upper and lower, with the two groups of sampling modules arranged in opposite directions.

[0032] In the right view, copper rod 3 represents the beginning, and in the left view, copper rod 3 represents the end. Connect one end of the standard source to the beginning of copper rod 31, connect the end of copper rod 31 to the end of copper rod 32, connect the beginning of copper rod 32 to the beginning of copper rod 33, connect the end of copper rod 33 to the end of copper rod 34, and so on. Connect the beginning of the last copper rod 3 to the other end of the standard source. In this way, all copper rods 3 can be connected in series.

[0033] The current sampling modules are divided into two groups, one above the other, with the lower sampling modules arranged in the opposite direction to the upper ones.

[0034] By applying current from a standard source, all current sampling modules can acquire one current signal, and the direction of the current entering the sampling module is consistent, thus achieving unified calibration and testing of multiple sets of currents.

[0035] This invention eliminates the need for the wire storage box 7, saving the back-and-forth wiring of each copper rod 3. With fewer wires, the force required to push and pull the copper rod 3 along the guide rail is reduced, making testing more convenient and faster. The simplified fixture structure, resulting in better reliability and durability, is also due to the reduced wiring. The sampling module is divided into upper and lower layers, increasing the number of sampling modules that can be tested simultaneously.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
