Embodiment 1

[0016] Embodiment 1, wherein the power supply to be aged is a UPS power supply, and the intelligent power supply aging method is implemented when the voltage is at high voltage, low voltage and normal voltage, including the following steps:

[0017] Step 1, first connect the aging power supply to the controller, and input the rated power and parameters in the manual of the aging power supply, such as inputting the voltage operation schedule and load operation schedule in the controller, where the voltage is high voltage , low voltage and normal voltage.

[0018] When the aging power supply is connected to the controller, the aging operation controller will read the rated power of the aging power supply through the RS232 communication interface, and then the aging operation controller will automatically select the appropriate input voltage connected to the aging power supply according to the situation, and the appropriate The output load connected to the source being aged. At ...

Embodiment 2

[0036] Embodiment 2 is different from Embodiment 1 in that the power source to be aged is an EPS emergency power source, and the aging method of the power source is the same.

[0037] The following is the relevant experimental analysis:

[0038] (1) When the EPS emergency power supply has a certain capacity, input different voltages and loads, and the ambient temperature is 50°C.

[0039] Take the capacity of the EPS emergency power supply as 10KVA, divide the mains power into normal output and fault states, input different voltages and loads, observe the temperature, output voltage and output frequency of the UPS power supply, and the results are shown in Table 3:

[0040] table 3

[0041]

[0042] From Table 3, the UPS temperature in this experiment is basically stable at about 50°C, and the internal electronic components work normally within this temperature. At the same time, when the mains input is within the rated input voltage (187V-242V) of the EPS emergency power...

Abstract

The invention relates to the technical field of power electronic detection, and particularly relates to an intelligent power supply aging method. The method comprises the following steps: 1, a voltage operation schedule and a load operation schedule are inputted to a controller; 2, in conditions in which an aged power supply has no input voltage and no load, the controller acquires rated information of the aged power supply; 3, in conditions in which the aged power supply has input voltage but no load, the controller sends a command to a switching unit, and corresponding voltage is accessed; and 4, in conditions in which the aged power supply is connected with loads and has input voltage, the aged power supply simulates user environments and is connected with loads of different natures in stages, the controller acquires state information B of the aged power supply in the load state, and whether the aged power supply is normal is judged. Abilities of bearing different loads and adapting to different user environments by the power supply under high voltage, low voltage and normal voltage can be intelligently detected.

Description

technical field [0001] The invention relates to the technical field of power electronics detection, in particular to an intelligent power supply aging method. Background technique [0002] A power source is a device that converts chemical energy into electrical energy. The size of the power supply, whether the current and voltage are stable, and whether the frequency is stable are all criteria for judging the stability of a power supply. The power aging test is a necessary inspection before the power supply leaves the factory. Through the power aging test, the stability of the power supply during the use of the customer terminal can be accelerated. Power aging is a non-destructive screening test technology that can eliminate early product failures. It simulates a test environment under high temperature and harsh conditions for long-term aging of high-performance power supplies to improve product safety, stability and reliability. process flow. At present, the power aging ...
