Abstract
The invention provides a parameter acquisition cabinet. The parameter acquisition cabinet integrates a parameter acquisition point of a test inverter, acquisition equipment and the like into a cabinet body. The acquisition equipment can accurately analyze each parameter of a grid-connected inverter and a charger. By using the parameter acquisition cabinet, test data acquisition of the different power-capacity photovoltaic grid-connected inverters and the chargers can be realized. By using an existing domestic and oversea grid-connected inverter and charger performance detection system, a manual mode is usually used to test during a test process so that system safety is poor. By using the parameter acquisition cabinet of the invention, the above problem is solved. In the prior art, a special data acquisition apparatus is not arranged, tedious wiring and clearing can cause a long detection period so that efficiency is low, test data consistency can not be guaranteed and the test is not convenient. The parameter acquisition cabinet can satisfy test demands of various kinds of occasions, and a grid-connected inverter and charger test and other functions can be completed.
