Embodiment Construction

[0021] The embodiment of the automatic pairing test system of the combiner box of the present invention includes a DC voltage test part, a DC voltage test part, and a test tool for fixedly installing the tested part. The DC voltage test part includes a standard DC current source, and the DC voltage test part includes a standard DC voltage source. The DUT consists of a measurement board and a manifold. Such as Figure 1-3 As shown, the test tooling includes a base on which a set of spring test pins 6 are provided for conductive insertion of corresponding terminals of the DUT during testing. The spring test pins include input spring test pins and output spring test pins. , to connect the corresponding input voltage source and current source, eliminating the need for wiring operations for each test.

[0022] The base 1 is provided with a placement plate 5 for placing the tested piece, the lower end of each spring test pin 6 is fixed on the base, the upper end of the spring test...

Abstract

The invention discloses a combiner box automatic pairing testing system and a testing tool thereof. The combiner box automatic pairing testing system comprises a direct voltage testing part, a direct voltage testing part, and a testing tool used for fixed installation of tested work pieces constituted by measuring plates and manifolds. The testing tool comprises a base, which is provided with a group of spring testing needles used for conductive inserted connection with terminals of tested work pieces during the test. Each spring testing needle comprises an input spring testing needle and an output spring testing needle. The base is also provided with a pressing mechanism used for pressing the tested work pieces tightly, after the tested work pieces are disposed on the spring testing needles. During the use, the to-be-tested work pieces are directly connected with the spring testing needles disposed on the base in an inserted manner, and the conductive connection between the corresponding terminals of the to-be-tested work pieces and the spring testing needles is completed. The bottom parts of the spring testing needles are connected with a voltage source or a current source by leads, and then during the test, the tested work pieces are only required to be connected with the spring testing needles in an inserted manner, and wiring operation is saved, and therefore testing efficiency is improved.

Description

technical field [0001] The invention relates to an automatic pairing test system for a combiner box and a test tool thereof. Background technique [0002] Photovoltaic combiner box is an essential device for building a photovoltaic grid-connected power generation system. In addition to completing the photovoltaic string confluence function, it can also collect various parameters in the box, such as string current, bus voltage, temperature inside the box, and the status of lightning protection devices. It is uploaded to the monitoring room of the photovoltaic power station through the bus, and can send an alarm signal to the background in the event of a sudden failure and automatically perform corresponding fault protection actions. During the production and debugging process of the combiner box, the measurement board and the manifold board need to be paired for testing. The debugger needs to connect 6 external 5V power lines, 2 external communication lines, and 2 300 DC volt...
