Description
Technical Field
The utility model relates to a high-voltage testing device, in particular to a high-voltage testing platform device of a photovoltaic module.
Background
High voltage testing of photovoltaic modules generally refers to qualification and pattern certification of photovoltaic modules having voltages above 1500 vdc and up to 2000 vdc. This work should be related to the performance of the photovoltaic module, but also to safety aspects and construction requirements. The object tested primarily covers photovoltaic panels, connectors, cables.
Safety requirements of photovoltaic modules with system voltages up to 1500V DC are specified in IEC61730-1, structural requirements are specified in IEC61730-1, and test requirements are specified in IEC 61730-2. While the IEC 61215 series of standards describes the performance and pattern authentication of photovoltaic modules with system voltages up to 1500 vdc.
The new specifications shall specify additional requirements for construction and testing of 61730-1 and-2 series photovoltaic modules above 1500V DC and below 2000V DC, as well as new requirements for IEC 61215 series performance and pattern certification.
The main safety aspect of photovoltaic modules that meet the 1500 vdc system voltage is electric shock. The dc module should also meet arc and shock conditions when the system voltage increases to 2000V. Thus, careful reconsideration of the photovoltaic module and its underlying components is required for clearance, creepage distance and solid insulation requirements. Accordingly, various tests for evaluating the safety of the photovoltaic module and its components, such as surge voltage, wet leakage, insulation thickness dimensioning and insulation tests, must be modified accordingly.
In addition, the Potential Induced Degradation (PID) of the photovoltaic module also creates additional risks that may affect its reliability for long-term operation. The risk of the photovoltaic module PID increases with increasing system voltage. Early photovoltaic modules exhibited significant degradation in the field. Thus, if the direct current system voltage of the photovoltaic module is up to 2000V, its PID sensitivity should also be ensured.
As photovoltaic module manufacturers continue to seek ways to increase solar cell, module, and system level efficiency and reduce cost, it is expected that nearly all photovoltaic modules in the next few years must meet the requirements of higher system voltages.
The existing high-voltage test of the photovoltaic module adopts a high-voltage power supply to be applied to the photovoltaic panel to be tested or other elements one by one so as to test the withstand voltage safety performance of the photovoltaic panel to be tested, but the test mode is difficult to effectively fix each test piece to be tested, batch test is not suitable, any error is caused by the ectopic position of the test process, the test efficiency is low, and a standardized test platform is required to be developed as key auxiliary equipment for the high-voltage test of the photovoltaic module.
