Problems solved by technology

[0004] It can be seen that in the existing test scheme, it is necessary to test the AC power distribution cabinet and the DC power distribution cabinet separately, which is time-consuming and power-consuming.
In addition, the mass production test in the factory involves the connection and disconnection of each power distribution cabinet, which requires a large amount of work

Abstract

The application discloses a test system and a test method for a power distribution cabinet, which relate to the field of electrical test. The power distribution cabinet test system includes an AC power supply, a tested AC power distribution cabinet, a rectifier, a tested DC power distribution cabinet and a load; the AC power supply, a tested AC power distribution cabinet, a rectifier, a tested DC The cabinet and the load are connected in series in sequence; the output voltage level of the rectifier device matches the DC power distribution cabinet under test; the load is adjusted to control the AC power distribution cabinet under test and the DC power distribution cabinet under test carry out testing. The application can save test time and reduce test power consumption.

Description

technical field [0001] This application relates to the field of electrical testing, in particular to a testing system and testing method for a power distribution cabinet. Background technique [0002] In industries such as petrochemical, electric power and data centers, various types of AC and DC power distribution cabinets are widely used to manage and distribute power. After the factory completes the production and manufacture of the power distribution cabinet, it is necessary to test the power distribution cabinet, which involves on-load testing, that is, energizing the power distribution cabinet and then running it with load to test the electrical and heat resistance of each component of the accessory cabinet . [0003] Due to the different electrical characteristics of AC and DC power distribution cabinets, they generally need to be tested separately under load. Such as figure 1 As shown in , the input of the AC power distribution cabinet is connected to the AC power...
