Description

Technical Field

[0001] The utility model relates to the technical field of UPS, in particular to a UPS power supply testing device. Background Art

[0002] UPS, or uninterruptible power supply, is an uninterruptible power supply with an energy storage device. It is used to supply power to equipment with high requirements for power stability. In communications, data storage equipment, control equipment and their emergency protection systems, the quality and stability of UPS power supply are very important to the product. Therefore, after the UPS power supply is produced, its battery performance needs to be tested. When the power supply is normal, UPS, as an AC voltage stabilizer, stabilizes the power supply and supplies it to the electrical equipment. At the same time, UPS will charge the battery. When a power outage occurs, UPS will use the battery's DC power to continue to supply AC power to the electrical equipment through inverter switching conversion, thereby achieving the function of keeping the electrical equipment working normally.

[0003] However, in actual usage, the UPS is electrically connected to multiple electrical devices. During the power outage and inversion process, the time intervals from power outage to power on of multiple electrical devices are different. Even when the power on and power off states are switched back and forth repeatedly, it may cause internal circuit failure of the UPS or inverter abnormality, resulting in individual ports electrically connected to electrical devices being unable to normally transmit the AC power generated by the inverter, which in turn causes individual electrical devices to be unable to use electricity normally during a power outage. Currently, there is no dedicated testing device for this purpose. Utility Model Content

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 and Figure 3 As shown, a UPS power supply testing device includes a UPS body 1 and a power supply 2, and also includes a test cabinet 4, wherein the test cabinet 4 is provided with at least one test cavity 5 which is evenly arranged from top to bottom, wherein partition plates 9 are fixedly connected between adjacent test cavities 5 in the test cabinet 4, wherein LED bulbs 6 are provided at the upper ends of the partition plates 9, and the UPS body 1 is electrically connected with at least one power-on wire 7 which is respectively electrically connected to each LED bulb 6, and the power-on wire 7 runs through the test cabinet 4.

[0022] Through the above structure, multiple LED bulbs 6 can be used to electrically connect to each power transmission port of the UPS body 1. How to test the reliability and power efficiency of the UPS body 1 through the status of the LED bulbs 6, the specific structure is as follows:

[0023] like Figure 1 and Figure 4As shown, the test cabinet 4 has photosensitive sensors 10 matched with each LED bulb 6 in the test cavity 5, and the test cavity 5 is adhered with a shading plate matched with the LED bulb 6, which can improve the accuracy of data detection of the photosensitive sensors 10 in each test cavity 5. The test cabinet 4 is provided with a data processing module electrically connected to the photosensitive sensor 10 and a control module electrically connected to the data processing module. The test cabinet 4 is provided with at least one data recording screen 8 matched with each photosensitive sensor 10, and the data recording screen 8 is electrically connected to the control module. The power supply 2 is periodically powered on and off at a certain frequency, and the control module is electrically connected to the power supply 2. The power supply 2 is provided with a display screen 3 for displaying the frequency and number of power-on and power-off, so as to facilitate observation of the total number of power-on and power-off cycles of the power supply 2.

[0024] Through the above structure, with the cooperation of the photosensor 10, the data processing module and the control module, the time delay of each LED bulb 6 lighting up can be detected when the power supply 2 is powered on and off for multiple cycles, and whether each power transmission port of the UPS body 1 is abnormal can be detected.

[0025] Embodiment 2

[0026] like Figure 1 and Figure 2 As shown, the test cabinet 4 is provided with an explosion-proof transparent window that matches the test cavity 5, and the test cabinet 4 is provided with at least one cooling fan that matches each test cavity 5.

[0027] Through the above structure, the explosion-proof transparent window can prevent fragments of the LED bulb 6 from flying out of the test chamber 5 and causing harm to the staff when the LED bulb 6 explodes, thereby improving the safety of the staff. The cooling fan can dissipate the heat generated by the LED bulb 6, further improving safety.

[0028] During the specific implementation of the utility model, when the UPS body is tested, the power-on and power-off frequencies of the power supply are preset, and the LED bulbs are electrically connected to the power transmission ports of the UPS body respectively. During the testing process, when the power supply is powered on, the UPS body works as an AC voltage stabilizer and charges the internal battery, and each LED bulb lights up normally. When the power supply is powered off, the UPS body works as an inverter and switches to an inverter working state to supply power to each LED bulb. If each power transmission port of the UPS body transmits power normally, the internal circuit of the UPS body works normally, and the UPS body switches to an inverter working state with high efficiency, the LED bulb always remains in a normally lit state.

[0029] During the detection process, when the power supply is cut off, the control module receives the data of the power supply cutoff, and the photosensor detects the brightness in each test cavity. If the brightness remains unchanged, the UPS body is working normally. The data processing module receives the data detected by the photosensor, and transmits the processed data to the control module. The control module determines the working state of the LED bulb according to the data of the photosensor and the signal of the power supply cutoff, thereby determining whether the power transmission port of the UPS body is working abnormally; if the LED bulb goes out first and then lights up, the power-on efficiency of the power transmission port electrically connected to the LED bulb becomes low, and at the same time, it can be determined when the LED bulb lights up based on the detection data of the photosensor, thereby obtaining the power-on delay data of the power transmission port; after the power supply is energized and deenergized for multiple cycles, if the UPS body fails and causes the power transmission port to fail, the LED bulb electrically connected to the transmission port will go out, so that the reliability and power-on efficiency of the UPS body can be detected after multiple cycles of energization and deenergization.
