Problems solved by technology

At present, the domestic testing of inverter products mainly relies on manually testing the technical parameters of the product item by item, which brings many problems during the test operation: 1. The wiring test is cumbersome and the test space is limited; 2. It is difficult to ensure accurate and stable measurement. 3. The efficiency of manual testing by workers is low, with an average of 24 units tested per day, and the product pass rate is only 85%, resulting in slow testing speed, low product output, and unstable performance indicators

Abstract

The invention relates to an inverter function test system and a test method. The inverter product is connected to the product inlet J through a wire. Under normal conditions, the charging data of the 120VAC battery B2 to be charged and the data Charging data, 120VAC fully charged battery B1 charging data, 277VAC fully charged battery B1 charging data, inverter discharge voltage meter VAC2, inverter discharge frequency table Hz measured 120VAC no-load inverter data, battery charging current meter IDC1, Inverter discharge voltmeter VAC2, inverter discharge frequency meter Hz, inverter lamp load ammeter IAC2 measured 120VAC full-load inverter data, battery charging current meter IDC1, inverter discharge voltmeter VAC2, inverter discharge frequency meter Hz, inverter lamp The load ammeter IAC2 measures the 277VAC full-load inverter data, records them in the test table and compares them with the standard data, and then transfers the product to the next process. The test items are complete, and the parameters are stable, clear and accurate.

Description

technical field [0001] The invention relates to the field of electronic product testing, in particular to an inverter function testing system and testing method, which are used to improve the testing efficiency of inverter products and ensure the consistency of product technical parameters. Background technique [0002] New energy, as one of the strategic emerging industries that China is accelerating its cultivation and development, will provide solid technical support and industrial foundation for the large-scale development and utilization of new energy. The demand for inverters is increasing year by year, and the country has stricter requirements on the technical parameters of inverters. At present, the domestic testing of inverter products mainly relies on manually testing the technical parameters of the product item by item, which brings many problems during the test operation: 1. The wiring test is cumbersome and the test space is limited; 2. It is difficult to ensure...
